Description
Technical field
The present invention relates to a kind of yarn feeding apparatus as described in the preamble according to main claim.
Background technology
Known yarn feeding apparatus (or abbreviate as " thread-carrier ") according to various operate.
First type is defined as the constant-tension thread-carrier, and the constant-tension thread-carrier can make described parameter (the peculiar parameter of yarn) remain requirements in the operational phase of giving the weaving loom send yarn and invariable.
Second type is defined as the storage type thread-carrier, and the storage type thread-carrier can be loaded into the programmable amount of thread on swing roller or the rotating member, then, is extracted out by weaving loom in this amount of thread semifinished piece production process.
Another kind of type definition is the constant basis thread-carrier, can guarantee that therefore it is constant giving the amount of thread of delivering to weaving loom in process of production.
The also known member or the cutter that can when entanglement occurring, cut off to the yarn that send; These equipment are controlled via electric pulse or the electromagnetic valve controlled by the control unit that often is associated with weaving loom usually.
These thread-carriers generally include the shell that is associated with rotating member, can be about this rotating member reel a circle or multiturn yarn.Yarn debatching from it self the package, to arrive weaving loom (loom, knitting machine, hosiery machine) when leaving thread-carrier, at the weaving loom place, suitable known members receives this yarn and handles this yarn to manufacture a finished product.
Based at least one measurement parameter (for example operating the torque rating of the electric actuator of this member) that can be relevant with rotating member or with at least one relevant measurement parameter of inherent characteristic (for example the tension force of yarn or yarn are to the speed of sending of giving of weaving loom) of yarn, send the correct yarn of control setup monitoring to be sent (no matter being sent) by giving of being associated with the thread-carrier shell by the yarn that the constant-tension or the mode of constant basis obtain.
Though known thread-carrier is correctly carried out the function that their plans should be carried out, but there is such technical limitation in they: if do not keep constant or meet and exceed predetermined threshold value by the parameter (for example yarn tension or speed) of thread-carrier monitoring, then thread-carrier forms rapid tension force in leaving the yarn of thread-carrier increases.This tension force increase can reduce the quality of finished product, perhaps damages some mechanical component (for example spicule on the knitting machine) that cooperates with yarn in the article of manufacture process.
And the tension error that surpasses predetermined threshold (characteristic of the yarn of handling) can cause the yarn deterioration, also can make yarn compare the variation (burr, elongate fiber, fiber extraction etc.) on the recurring structure with its standard feature in addition.
For example, in the situation of constant-tension thread-carrier, if the tension force in entering the yarn of thread-carrier surpasses the torque peak (for example because doff, debatching or obstructing problem) of the actuator (electro-motor) of rotating member, then this actuator can not keep the constant of tension force, and therefore in leaving the yarn of thread-carrier, stay the marking that rapid tension force increases, and therefore near the point that yarn is incorporated into weaving loom, also stay the marking.
In the situation of storage type thread-carrier, if needing motor or actuator that the moment of torsion that approaches maximum rating is provided the required tension force of yarn debatching from package, then this thread-carrier equipment is banked up wire turn on the cylinder with very high tension force.This causes thus in the defective separation between the wire turn (i.e. compacting between the wire turn of banking up under the high tensions), makes the quality that can not guarantee production process when the wire turn of weaving loom at these high tensions of extraction.
For the constant basis thread-carrier, if surpass maximum motor torsional moment at the tension force that yarn debatching from package is required, it is constant that then actuator device can not keep the rotative speed of rotating member, thereby cause rapid tension force to increase in the actuator exit, the tension force that causes entering in the yarn of weaving loom increases.
This means that for all aforesaid thread-carriers the goods by described weaving loom production all are defective and/or can not meet the parameter of expectation.
DE4016964 has described a kind of yarn in knitting machine and has been sent member, wherein, is provided with cutting equipment along the path of giving the yarn of delivering to weaving loom.In this equipment, yarn cooperates with movable link, moves the cutter control member that is contained in equally in the described equipment to start in the situation that the tension force of this movable link in yarn increases suddenly.
Control member can be the mechanism of for example lever system or micro-switch, and this mechanism provides power for when closure the cutter actuator member.Say in essence,, always must have the motion of wanting the movable link that yarn cooperates with it in order to realize the startup of this control member.
Yet, this scheme is subjected to the influence of the entrained Residual oil that is accumulated in dirt in the cutting equipment or dust and enzymolysis of yarn, this dirt, dust or Residual oil may both can disturb the motion of movable link, also can disturb the motion of control member, thereby hinder and correctly start cutter when needed.Even in the situation of fine motion control member, any dirt or other sediments also can cause false contact, this can cause when not required and carry out cutting operation (thereby causing tangible problem), perhaps causes and does not carry out cutting operation, thereby bring counter productive on weaving loom is produced.
Summary of the invention
The objective of the invention is to solve with the yarn that enters thread-carrier in the relevant technical matters of tension variation, therefore the constant-tension in the yarn that this variation causes can not keeping withdrawing from makes weaving loom produce defective goods.
Special purpose of the present invention provides a kind of thread-carrier equipment that is provided with the yarn cutting element, and this thread-carrier equipment can solve the problem of pointing out previously.
Another object of the present invention provides a kind of thread-carrier equipment of the type of setting forth previously, and this thread-carrier equipment in use is that failure-free and its size are less, makes it possible to easily to be placed on it on the weaving loom or near the weaving loom.
Another purpose provide a kind of can occur off-square give send tension force whenever all interrupt give the thread-carrier equipment that send yarn to weaving loom, described interrupt operation is not directly to take place in the effect that is used on the control member of cutter by yarn, the effect of yarn can cause starting undesirably cutter, and perhaps cutter is not blocked on yarn.
Special purpose of the present invention provides a kind of equipment of the type of setting forth, this equipment can be given and send yarn and directly monitor any yarn property (for example tension force, speed or give the amount of sending) simultaneously or monitor any yarn property (for example giving the characteristic of the member that send yarn) indirectly, and based on this monitoring, this equipment can start cutting element so that the yarn that whenever all interrupts that does not meet expectation value in this characteristic that monitors is given and to be sent, and the start-up operation of described member with under the situation that the control member that is used for described cutting element cooperates does not take place at yarn.
For the expert of this area will be that conspicuous these and other purpose will obtain by the feeding apparatus according to claims.
Description of drawings
The accompanying drawing that the present invention provides by the mode with the indefiniteness example will become more apparent, in the accompanying drawing:
Fig. 1 is the lateral plan of thread-carrier formed according to the present invention;
Fig. 2 is the block diagram of the equipment of Fig. 1; And
Fig. 3 is the diagram of circuit of operating mode that the equipment of Fig. 1 is shown.
The specific embodiment
With reference to described accompanying drawing, Fig. 1 illustrates equipment 1, and equipment 1 in this example can be by with yarn F debatching and give with constant tension force and to send yarn F from corresponding package (not shown).
Yet, equipment of the present invention can be a kind of like this general-duty thread-carrier: this thread-carrier can guarantee that the characteristic of the yarn that send of giving is (except that tension force, also comprise speed or quantity) constancy, wherein said characteristic is the parameter of the member by the described equipment of monitoring for example and directly or indirectly assessment is as mentioned below.
Equipment 1 comprises the box-type shell 1A of the functional element that holds this equipment.The functional element of this equipment comprises the rotating member 2 that is subjected to actuator 3 controls.The electro-motor of actuator 3 for operating under the control of programmable control unit 5, this control unit 5 is preferably the microprocessor type that is embedded among the shell 1A.
Control unit 5 also cooperates with tension pick-up or measurement member 8, the tension force of this tension pick-up or measurement member 8 and yarn F mutual action and measurement yarn F.This sensor for example is a force transducer.According to the tension force of the yarn F that measures by tension pick-up 8 and according to this tension force and the comparative result that is stored in the predetermined value in the memory cell, this control unit 5(is in known manner) actuator or motor 3 are sent instruction (actuator or motor 3 are quickened or slow down), leaving arrow K among equipment 1(Fig. 1 so that make) and keep constant towards the tension force of the yarn of weaving loom T guiding.
As the alternative or the additional aspects of aforementioned schemes, unit 5 can cooperate with the speed sensor 10 that operationally is associated with rotating member 2; In this way, give the send speed of yarn F to weaving loom T can be measured in unit 5, and therefore can measure give the send amount of yarn to weaving loom T.
Yarn cutting element or abbreviate cutter 13 as and also be connected to unit 5, and based on the variation of the variation of at least one monitoring parameter in yarn tension and the speed or the moment of torsion that absorbed by motor 3 (for example electric current that is absorbed by motor 3 or other known method), this cutter 13 can be by described unit starting.Cutter be enabled in yarn F do not act directly on the cutter act on the mechanical component that is connected to described cutter or the situation on the electric components (for example micro-switch) under take place; Based on yarn property (the directly or indirectly yarn property of measuring) or based on sending relevant value with described giving, described startup always and only takes place by the intervention of unit 5.Therefore, only and always based on functionally interrelating with described yarn but be not the instruction that is directly generated by this yarn, cutter acts on this yarn.
By this way, no longer can influence the signal that the Cutting Control device starts, therefore provide more the failure-free yarn to sending and controlling by the dirt of yarn transmission, dust etc.
Control unit 5 has at least one the certain threshold level in the described parameter that is stored in its memory cell (not shown).If yarn F will stand braking (for example owing to being stuck in the braking that causes in package or the bobbin) the process of its debatching from package, in the then aforementioned parameter of being monitored at least one changes its value (for example, the moment of torsion that is absorbed by motor increases the yarn with the braking that stretches) until reaching threshold value.In this case, for prevent yarn F to be different from the tension force (this tension force is stored in the unit 5) of having programmed thus tension force leave the potential problem that equipment 1 causes the goods of producing for weaving loom T, unit 5 starts cutter 13, and this cutter 13 cuts off the yarn F of access arrangement 1.
This cutter be known type and comprise shell 20, shell 20 preferably mechanically is attached to the shell 1A of equipment 1 and has movable cutting element, this movable cutting element is operated and in a known way by electric control (for example by electromagnet control), in order to block yarn F when needed and to cut off this yarn F.
Therefore, as long as the unit 5 of equipment 1 detects in the tolerance interval that the parameter of being monitored no longer is in value and arrives and/or surpass predetermined threshold, before then the tension force increase in leaving the yarn F of equipment 1 can cause that defective goods form, the cutting element of this unit starting cutter 13 (and preferably, this unit suspends this weaving loom T).In two kinds of situations, described unit all starts cutter 13.
Especially, in the situation of constant-tension thread-carrier, when unit 5 detected equipment and can not guarantee the constant-tension of the yarn F that withdraws from, this unit 5 started cutters and suspends weaving loom.To reach at yarn F before the tension force of the defective goods of feasible formation, moment of torsion by monitoring motor or actuator, or its current draw (may pass through regular time or programmable during the time when moment of torsion for example surpasses based on the predetermined value of maximum nominal torque or programmable value, unit 5 detects and enters " critical " district), or the tension force that leaves the yarn of thread-carrier (may pass through regular time or programmable after the time when this tension force for example surpasses based on the predetermined value of the tension force of setting or programmable value, unit 5 detects and enters " critical " district this moment), unit 5 can also be intervened in advance.
In the situation of storage type thread-carrier, as long as the yarn tractive torque that unit 5 detects on rotating member is non-constant, then this unit 5 starts cutter and suspends weaving loom.The current draw that acts on the motor torsional moment on the rotating member 2 or be used to load the yarn wire turn by monitoring simply (may pass through regular time or programmable after the time when it for example surpasses based on the predetermined value of maximum nominal torque or programmable value, unit 5 detects and enters " critical " district), or be present in to sending number of wire turns on the cylinder (when owing to cause this number of wire turns less than for example having passed through regular time or programmable after the time based on the predetermined value of the number of wire turns of setting or programmable value from the tractive force of the yarn of package, unit 5 detects and enters " critical " district), this equipment can be intervened in advance.
At thread-carrier is in the situation of constant basis type thread-carrier, as long as no matter unit 5 detects and can not guarantee constantly when giving the amount of sending for any reason, then this unit 5 starts cutters 13 and suspends weaving loom.As the fwd situation, the actual speed of moment of torsion or rotating member by monitoring motor 3 is (in the operating process of weaving loom T, when its less than for example having passed through regular time or programmable after the time based on the predetermined value of the speed of setting or programmable value, unit 5 detects and enters " critical " district), unit 5 can be intervened in advance.Fig. 3 illustrates the diagram of circuit that can understand the interference method of control unit 5 in more detail.
According to the content shown in this figure, in frame 1, unit 5 carries out initialization for the required variable that send yarn F (constant-tension, constant basis, or be used for the variable of the proper operation of storage type thread-carrier) in the mode that limits in advance to being used to monitor to weaving loom T.For example, in frame 1, the value scope of the value scope of the tension force of unit 5 qualification yarn F or the driving torque of actuator or motor 3 is sent yarn F for giving to weaving loom T with the suitable tension force of correct article of manufacture, and the corresponding value of being measured and being detected by described unit must remain in this value scope.
In frame 2, the parameter (for example tension force or moment of torsion) of being monitored by unit 5 is measured.For example, if tension force is monitored, then the signal that is derived from sensor 8 is analyzed; If the parameter of being monitored is a moment of torsion, then for example measure the electric current that absorbs by motor 3.
In frame 3, whether the value of the parameter that unit 5 checks are measured surpasses preset threshold, in the situation of driving torque, this preset threshold can be the constant that depends on specified motor torsional moment or programmable value (the same with the situation of the measurement of the amount of thread of tonometry or absorption).If comparative result shows the observed reading of the parameter of being monitored less than threshold value, then treatment step turns to frame 4, at frame 4 places, the alarm count device (not shown) that is connected with unit 5 is reset.Then, treatment step turns back to frame 2.
If situation is opposite, promptly the parameter of being monitored has the value above threshold value, and then treatment step turns to frame 5, and at frame 5 places, the alarm count device increases.Then, treatment step turns to frame 6, and at frame 6 places, whether the value of unit 5 monitor counters surpasses predetermined value.This operation is carried out based on " time filter " of this value of definition (being the value above threshold value of the maximum of the parameter of being monitored).If the value of counting machine is less than time filter, then treatment step returns frame 2; Alternatively, treatment step turns to frame 7, and at frame 7 places, unit 5 starts alarm signals (vision and/or the sense of hearing) and suspends weaving loom T.Then, treatment step promptly turns to frame 8, and at frame 8 places, unit 5 starts cutter 8.Then, treatment step returns frame 2.
According to the thread-carrier that is adopted, the diagram of circuit of Fig. 3 obviously can be based on different monitored parameterses or parameter and is changed, for example, based on be present in number of wire turns on the rotating member, leave equipment 1 yarn tension force etc. and change.
Rely on the present invention, realized control overall manufacturing.And if in the upstream of thread-carrier the yarn entanglement takes place, then these yarn entanglements can not have influence on its side that withdraws from by any way, thereby can not cause the quality problems in the finished product or stitching be formed the damage of member.This scheme can also be preserved the quality and the technological characteristics of yarn.
Should be pointed out that according to the present invention unit 5 also preferably suspends weaving loom T except starting cutter, thereby make weaving loom T normally stop and can not consuming yarn storage on the thread-carrier.
Described and proposed various embodiment of the present invention.Yet according to fwd explanation, other embodiment also is possible (for example the shell 1A of cutter 13 and equipment 1 separate this embodiment), and these embodiments fall in the scope of appended claim.
