Summary of the invention
The purpose of this invention is to provide the possibility that is used on mounting rod, installing and locating thread sensors, realize the simple and safe indication of silk thread fracture thus, and realize the safe shutdown of machine in this case in simple mode.
Utilization realizes this purpose according to the line feeding equipment of claim 1:
Line feeding equipment of the present invention comprises at least one thread sensors with silk thread sensory rod, and described silk thread sensory rod can preferably be positioned at the position that can select at random at least along keeping bar to be installed to the maintenance bar.Described silk thread sensory rod is supported on the thread sensors movably, and in this case, there is and keeps the primary importance of tensioning in it and distinguish between the silk thread fracture or the lax second place at silk thread.It comprises with keep on the bar or among or on the shell or among the position sensor contactless position pick-up of cooperating mutually.For example, described position sensor comprises a mechanical transmission component, and this mechanical transmission component is independent of the installation site of thread sensors and can is driven or be moved by the silk thread sensory rod along keeping bar to extend also.If the silk thread sensory rod is positioned at its primary importance, then described driving element also is positioned at its primary importance.If the silk thread sensory rod is positioned at its second place, then described driving element also is positioned at its second place.Described switching device preferably only is to be linked together with driving element so that the single switch that is driven by described driving element.If driving element is positioned at its primary importance, then switching device is in its first state.If driving element is positioned at its second place, then switching device moves to its second state, and this second state is different from first state.
Yet position sensor also can be without any removable driving element.For example, each thread sensors is associated with switching device, for example be fixedly placed on the reed contact that keeps on the bar and be associated.Can also keep arranging a plurality of reed contacts on the bar, these reed contacts are closely close mutually, to such an extent as to drive each thread sensors by at least one reed contact all the time, and regardless of the position of sensor on the maintenance bar.In this case, all reed contacts constitute the position sensor according to Patent right requirement 1 together.Can also arrange reed contact in adjustable mode.In addition, can will keep bar be configured to make it to move around with respect to the shell of line feeding equipment.And, can will keep bar to be configured to and can to pull it to be similar to flexible mode.
In other line feeding equipment, also can use thread sensors with above-mentioned design, promptly can with the shell of line feeding equipment or its special shell mechanism (such as, for example keep bar) those thread sensors of connecting with engaging.For this reason,, the shell of line feeding equipment is connected to suitable mounting structure, promptly is connected to the maintenance bar with the same in the situation of the line feeding equipment that describes in detail by exemplary embodiment.In the enclosure portion and/or bar inner or on the various maintenance structures or among switching device is set, described switching device is to drive by shell wall.
In addition, one or several position sensor can be set, it is driven by the gathering-device of different thread sensors via mechanical fixation.Described gathering-device can be the device that for example conducts magnetic field, for example the magnetizable metal line.Near if the magnetic field the magnetizable metal line that outwards pivots and enter in the thread sensors, then described metal wire conducts to magnetic field switch element such as for example sealing contact-relay (reed contact) or conducts to another magnetic field sensor, thereby drives described sensor.
Therefore, the position of switching device monitoring driving element.Can start driving element by one or more silk thread sensory rods.Under the situation of using driving element, about the response position actuating logic OR computing of silk thread sensory rod.Do like this, described response position is by the obtained position of corresponding silk thread sensory rod when silk thread ruptures or relaxes.In case have only one to arrive its response position in a plurality of silk thread sensory rods, then driving element leaves its off position with regard to deflection.Switching device detects this situation and produces corresponding signal.This corresponding signal can be used for operating the signal lamp that preferably is arranged on the line feeding equipment.Therefore described signal lamp responds, and thus, which thread sensors has received where unimportant signal and this thread sensors of silk thread fracture or silk thread tensioning deficiency are positioned at definitely.Signal can also be transferred to the machine controlling organization and be used for making knitting machine to shut down.
Basically, the silk thread sensory rod can be the element that is supported in the mode that can move at random.Yet, preferably the silk thread sensory rod is supported for it can be rotated around pivot axis.Do like this, it is neat that pivot axis preferably is parallel to the maintenance pole pair.Preferably, be provided with in order to towards the response position of silk thread sensory rod and the pre-tightening apparatus of pretension silk thread sensory rod.Pretightning force is resisted mutually therewith, and the silk thread sensory rod is by current silk thread push operation position.In most of the cases, (be lower than 1g with extremely low thread tension; Under extreme case, reach 0.8g to 0.6g) come elasticity of supply line.At operating position, this minimum thread tension is enough to thread sensors is remained on its obtained position.Along with reducing of thread tension, the silk thread sensory rod rotates to response position around pivot axis.
Pre-tightening apparatus is weight element (weight element) preferably.This weight element contacts with the pivot axis of silk thread sensory rod, thus along the described sensory rod of direction tensioning of its activation point.The pre-tightening apparatus of being represented by weight has progressive effect, that is to say, along with the increase of angle of pivot, the torque that acts on the silk thread sensory rod increases.This in addition can be arranged in the magnetic intensity and the more reinforcements of bar of the magnet of screw rod.
In case silk thread has been pivoted to response position, then can not be pivoted back to its operating position by silk thread (tension force is about 1g) again.This must manually carry out.By checking indicator lamp, which the line feeding equipment (" resilient roller ") that the operator can pick out knitting machine has caused the position of shutting down and can come this equipment.Consider the position of silk thread sensory rod, which rhizoid line of operator's identification line feeding equipment has caused shutdown.Therefore, pre-tightening apparatus has represented to make the silk thread sensory rod to be parked in the locking device of response position.
Preferably, described weight element being arranged as can be adjusted.This means the distance that to regulate weight element and pivot axis.For example, weight element can be the nut that is placed on the respective threaded rod.Screw rod can be configured to have the permanent magnet in magnetic field, and described magnetic field moves driving element when magnet itself is mobile.Alternately be, screw rod can be made by nonmagnetic substance, and the nut that is maintained on the screw rod can be configured to permanent magnet.Can also be independent of weight element, permanent magnet is provided on thread sensors, described magnet is set to start driving element.Preferably, mechanical transmission component is to be suspended to the bar that it can swing back and forth, and described bar extends along the whole length that keeps bar.Preferably, described bar is positioned at the interior volume that keeps bar.The pivot axis of described bar preferably is parallel to the maintenance bar, that is to say, is parallel to the latter's longitudinal direction.Preferably, form by for example soft magnetic materials such as steel or iron as the described bar of driving element.
Preferably, the weight by driving element itself make driving element under its off position by pretension, thus, it freely is suspended on as pendulum at the dead-center position place and keeps in the bar.Because one magnetic field in the thread sensors, described bar can move away this position.
Preferably, come connecting wire line sensor and driving element with magnetic field.This magnetic field can come from and be connected to thread sensors and the therefore permanent magnet that supported of removable mode.Can also arrange one or more permanent magnets in a fixed manner, in this case, a minimum thread sensors is connected to magnetic closure member (magnetic closure element), and this magnetic closure member is independent of the position (operating position or response position) of thread sensors and changes being connected between permanent magnet and the driving element.In addition, driving element itself can be configured to permanent magnet, so that for thread sensors provides the soft magnetism control member, it causes the attraction of driving element once more near mechanical transmission component the time, therefore makes driving member deflection.Driving element and thread sensors can also be configured to permanent magnet or for they provide permanent magnet.

The specific embodiment
Fig. 1 illustrates line feeding equipment 1, and this line feeding equipment 1 is set to supply with a minimum rhizoid line 2 in controlled mode to knitting machine or another silk thread that does not specifically illustrate consumption machine.Do like this, silk thread 2 is rolled out from line roller 3.
Line feeding equipment 1 comprises shell 4, and an end of shell 4 is provided with the anchor clamps 5 that are used for install machinery ring (machine ring) 6.Machine ring 6 is annular retaining devices on knitting machine for example, in the above, be equipped with many have shown in design or also have the line feeding equipment 1 of other design.Do like this, shell 4 is radially outstanding from machine ring 6.
Being arranged on the shell 4 is the axle 7,8 that can see in Fig. 2 especially, passes shell described axle horizontal and also rotatably is supported in the shell 4.In the axle 7,8 at least one is connected to pulley 9 via the transmission connection piece that does not specifically illustrate, described pulley is disposed near the upside of the shell 4 the anchor clamps 5 and is set to come transmission by belt or by motor.Preferably, come two axles of transmission 7,8 by pulley 9 along same direction.Pulley 9 is around preferably rotation 10 rotations of orientation vertically.
Axle 7,8 is arranged to and is parallel to each other, and is set to hold one or more bobbins.Fig. 2 only is illustrated in the line roller 3 of a side of shell 4 as example.In the axle 7,8 each can be held one or two, also can randomly hold a plurality of bobbins in shell 4 both sides.
Below shell 4, preferably be parallel to axle 7,8 ground and be furnished with maintenance bar 11, described bar has the approximate length that is equivalent to the length of axle 7,8 or surpasses described length slightly.Do like this, keep the bar 11 outstanding both sides that surpass shell 4.For example fairlead 12 can be clipped in the appropriate location on the described maintenance bar, thus, a rod 13 can project upwards from each described fairlead.The rod 13 of fairlead 12 is set to anti-principal vertical line roller 3 and skids off axle 7,8.
Extend extension 14 in a downward direction from the bottom of shell 4, described extension supporting keeps bar 11.Signal lamp 15 can be arranged on the top or the bottom of extension 14.Alternately, this signal lamp can also be arranged in another some place, for example at 16 places, end away from anchor clamps 5 of shell 4.Signal lamp 15 is used for signaling such as, error condition such as silk thread fracture for example.
In order to detect silk thread fracture, as by Fig. 1 and Fig. 2 and by the independent diagram among Fig. 6 conspicuous, use one or more thread sensors 17.Keeping bar 11 is to design in order to hold thread sensors 17 especially.Described maintenance bar has one, two grooves preferably.In this exemplary embodiment, this is first undercut groove 18 that is configured on the side that keeps bar, and described bar has the preferably cross section of approximate ellipsoidal, and longitudinally is straight.Preferably, first groove 18 is undercutting.It has L shaped cross section.Downside keeping bar 11 preferably is provided with second groove 19 as engagement grooves, and it has the cross section of approximate U-shaped.Keep bar 11 to surround a hollow space 20, this hollow space 20 is preferably extended along the whole length that keeps bar 11 with constant cross section.Yet, can also make to keep bar 11 not have groove.Can thread sensors be installed on non-directly (nonpositive) or direct (positive) mode and keep bar 11.
On the end of branch 23, arm 23a, 23b preferably interconnect via part 25 equally, and described part 25 is provided with towards the zone of part 24 bendings, and described zone is coupled in the groove 19.Two branches 22,23 interconnect at one end and two of being gone out mutually in line by appearance support eyelets 26,27.For example be supported on pivotally in the described eyelet by the thread silk thread sensory rod 28 of bending metals.For this reason, but the hub switch side of silk thread sensory rod be set to contact with silk thread 2.For this reason, it can be provided with the line roller 29 of for example ceramic or even plastics, and described line roller is supported on the silk thread sensory rod 28, so that rotatably motion.Can the line roller be set to have axial length greater than its diameter.This allows silk thread to have certain horizontal mobility, therefore allows silk thread to move back and forth at axle 7 at described silk thread when line roller 3 rolls.
Silk thread sensory rod 28 preferably is connected to towards the pre-tightening apparatus 30 of response position pretension silk thread sensory rod.For example, response position is shown in Figure 4.For example, pre-tightening apparatus 30 is weight element 31, and this weight element 31 for example takes to be placed in the form of the nut on the screw rod 32.This screw rod radially leaves rotation 33 and extends, and described rotation is limited by the support eyelet 26,27 that is used for silk thread sensory rod 28.At this moment, being oriented to of pivot axis 33 is parallel to maintenance bar 11.
Screw rod 32 and/or weight element 31 are configured to permanent magnet.From magnetic field that permanent magnet sends be arranged in hollow space 20 or also cooperate mutually alternatively at the driving element 34 that keeps bar 11 outsides.As for example illustrating individually among Fig. 5, driving element 34 is bars 35, and it preferably is made up of soft magnetic materials (for example steel), and extends on the whole length of hollow space 20.This bar is supported for and can pivots around pivot axis 36, being oriented to respect to pivot axis 33 or with respect to the level of the longitudinal direction that keeps bar 11 and parallel direction of described pivot axis.In addition, being oriented to of pivot axis 36 is parallel to groove 18,19.At its non-operating state, bar 35 vertically hangs from rotation 36 owing to the weight of itself.Rotation 36 can be represented that described bar 35 is supported in the recess that is arranged in the end cap 37,38 that keeps bar 11 (Fig. 2) movably by the corresponding extension of bar 35.Mode with low friction supports described bar 35.For this reason, integral hinge or sheet spring supporter are set.
From keeping bar 35 to extend tab 39, this tab is at its end upper support permanent magnet 40.Preferably, tab 39 is oriented to radially towards pivot axis 36 and leaves bar 35.Permanent magnet 40 produces magnetic field.Sealed contacts 41 or other magneto sensor form switching device 42 with permanent magnet 40.Switching device 42 is formed for the position sensor 43 of the position of each silk thread sensory rod 28 with driving element.
Can be provided for opening and closing the sealed contacts 41 of signal lamp 15.In addition, for example, can described contact be connected to control device, so that one response in described control device transmission signal notice thread sensors 17 via being arranged on the one or more circuits on the machine ring 5.
Line feeding equipment 1 described so far is set to following operation:
Under operator scheme, axle 7,8 is with substantially at the uniform velocity rotation.Line roller 3 is with constant speed line feeding.In order to detect the existence of silk thread 2, thread sensors 17 is arranged the position of online roller 3 belows.For this reason, the operator is hooked to the part 24 of retainer 21 in the groove 18 and part 25 and groove 19 is locked together.At this moment, branch 22,23 is setovered slightly mutually also leaves mutually.Conspicuous as the position institute from Fig. 1 to Fig. 4, against the downside tensioning downside branch 23 that keeps bar 11.As a result, retainer 21 is maintained at and keeps on the bar 11.Can move this retainer 21 along retainer 11 along the longitudinal direction.Particularly downside branch 23 ought be compressed slightly downwards,, this retainer 21 can be moved so that loosen clamping when action of two branches 22,23 slightly.
When thread sensors 17 being installed as required and having placed silk thread 2, therefore motion on the online roller 29 of described silk thread is pressed onto silk thread sensory rod 28 in the operating position.Fig. 1 to Fig. 3 illustrates operating position.On described operating position, silk thread sensory rod 28 extends downwards relatively sharp.Described silk thread sensory rod is with screw rod 32 bevels.Therefore, screw rod 32 and alternatively the gravity of weight element 31 produce the torque that silk thread sensory rod 28 is pressed against silk thread 2.
For example, be designed to the maintenance bar 11 that the magnetic field penetration of the screw rod 32 of permanent magnet is made up of for example plastics or nonmagnetic substance, and the hollow space 20 that enters described bar.Yet because relatively large distance between screw rod 32 and the bar 35, magnetic field is minimally or do not influence the position of bar 35 only.Therefore, described bar hangs down basically vertically.With reference to position shown in Figure 3, the permanent magnet 40 that is connected to described bar and sealed contacts 41 are at a distance of relatively large distance.Therefore, sealed contacts 41 do not respond.
If silk thread 2 relaxes or breaks, then the pre-tightening apparatus 30 with weight element 31 and/or screw rod 32 forms is pivoted on the response position silk thread sensory rod 28.Fig. 4 illustrates this response position.As the result of pivoting action, the screw rod 32 that is configured to permanent magnet move to now bar 35 near.The magnetic field penetration of described bar keeps the wall of bar 11 and makes bar 35 deflections.Described bar 35 moves towards screw rod 32.Similarly, permanent magnet 40 moves towards sealed contacts 41, and therefore described sealed contacts 41 respond.Thus, can engage light 15.
At the axial location that keeps on the bar 11, this operation all takes place regardless of thread sensors 17.The installation of thread sensors 17 only need place it in and keep on the bar 11.Do not need to set up and electrically contact.
As indicated in the mode of strictness signal among Fig. 5, the operating principle that is proposed is worked under the situation of using a plurality of thread sensors in an identical manner and independently.Even the only approaching described bar 35 in screw rod 32a, 32b or the permanent magnet, described bar also can outwards pivot, and permanent magnet 40 is moved and close sealed contacts 41.Therefore, bar 35 or driving element 34 are formed for the mechanical OR contact of one response in a plurality of thread sensors.
Though invade in respect of dust in advance in actual applications, various thread sensors 17 can be positioned on the maintenance bar 11 and operation thereon under the situation of non-interference.Do not need to set up and electrically contact.Bar 35 automatically detects the position of all thread sensors.Therefore, even have only the thread sensors of an installation to respond, described bar also can form a sensor that in fact responds.It is evident that the technical solution of proposition is characterised in that it is simple especially and healthy and strong.
Fig. 7 illustrates another embodiment of the present invention.This embodiment does not need the bar that supported movably.Here, position sensor 43 is the chains that for example are configured to each sensor composition of sealed contacts 44 to 49, described sealed contacts 44 to 49 are arranged to close mutually, and make each magnetic field of magnet of different thread sensors 17 drive at least one in the sealed contacts 44 to 49 all the time, regardless of each thread sensors 17 in the vertical installation site that keeps on the bar 11.Under the simplest situation, as shown in the figure, it is electrically connected in parallel.With one driving in the sealed contacts 44 to 49, be that the closure of its contact is thought signal.Even when having only a silk thread sensory rod 28 outwards to pivot, this also can take place.
Alternately, can also use the sealed contacts that comprise normally-closed contact, open when the intensity of described normally-closed contact in the magnetic field that penetrates them increases.For example, then these type of sealed contacts are connected in series simply.Sealed contacts 44 to 49 can be arranged in and keep on the bar 11, or even in its inner space.This structure can also be applied to other line feeding equipment, and the thread sensors 17 of design shown in wherein can locating and it comprise the shell with suitable maintenance or mounting structure.Each keep structure near with the number of expectation-described in above-mentioned exemplary embodiment-arrange sealed contacts 44 to 49, have in other words, can drive their mode by the magnetic field of each thread sensors 17.
Line feeding equipment 1 according to the present invention comprise keep bar 11, driving element 34 to be supported in a movable manner on this maintenance bar 11 or among.This element with equate and preferably the mode of magnetic detect at least one response in a plurality of thread sensors 17.Can come to determine to keep the position and the number of the thread sensors 17 on the bar 11 as required.When one in the thread sensors respond, be its silk thread sensory rod when moving to response position, driving element deflection takes place leave its off position.The deflection of driving element is detected by switching device 42 and can be indicated by signal lamp 15.
