Description
Technical field
The present invention relates to straight-bar machines, especially relate to the traversing control of needle-bar.
Background technology
In straight-bar machines, front and back possess for example a pair of needle-bar, and the needle-bar that for example makes one side with respect to the opposing party's shog freely.By making the needle-bar can be mutually traversing, and the scope that expansion can make coil move can weave various knitted fabrics.Herein, traversing by servomotor control needle-bar, in the time not making shog, by servomotor as servo brakes.But for as servo brakes, need to carry out excitation to the coil of servomotor, need electric power.And on the other hand, the major part of the braiding process of knitted fabric (stroke of cam carrier), according to the difference of knitted fabric, for example 80% left and right is the traversing process that there is no needle-bar.
Therefore not carrying out in the traversing process of needle-bar, consider to make the brake (servo brakes) based on servomotor to cut off, and utilize other brakes to fix needle-bar.But inventor has discussed this point, find, on needle-bar, sometimes apply sliding force from knitted fabric or cam carrier, even in not traversing process, while utilizing brake braking, needle-bar also may move absent-mindedly.In braking based on brake, after moving, needle-bar can not reset into original position in addition.So braiding is still proceeded when needle-bar is positioned at the position different from weave data.On the other hand, by servo brakes, can reset into original position.Therefore need investigation to switch under what conditions servo brakes and other brakes.
In addition about robot etc., known, be arranged on the brake outside servomotor, during not utilizing servomotor driving shaft, servomotor is cut off, make brake connect (patent documentation 1:JP2000-308990A).The excitation that does not need thus servomotor, has realized electric power saving.But, for the situation of straight-bar machines, only do not utilize servomotor driving shaft, do not carry out traversing, while switching to brake from servomotor, sometimes as mentioned above can be owing to from the power of knitted fabric or cam carrier, needle-bar being moved absent-mindedly.
Patent documentation 1:JP2000-308990A
Summary of the invention
Problem of the present invention is to prevent the neglectful movement of needle-bar, and reduce and will make the servomotor of shog as the frequency of servo brakes, thereby realize electric power saving.
The invention provides a kind of straight-bar machines, at least one pair of needle-bar before and after possessing, by traversing use and be also used as the servomotor of servo brakes, make at least one party's needle-bar freely traversing along the length direction of needle-bar with respect to the opposing party's needle-bar, the pin of the cam carrier operation needle-bar by moving back and forth on described at least one pair of needle-bar and making knit fabric, be provided with: brake, for forbidding the traversing of traversing needle-bar freely; And sliding force calculating part, obtain the sliding force that puts on traversing needle-bar freely from knitted fabric or cam carrier for the weave data based on knitted fabric.Sliding force is herein in addition so that the power that the mode of shog applies becomes the reason that needle-bar moves absent-mindedly from servomotor.It is characterized in that, possesses output interface, for below the sliding force of obtaining is the first setting and while not making shog by described servomotor, remove the excitation of described servomotor and described brake is connected, make shog in the time that the sliding force of obtaining exceedes the first setting and by described servomotor time, to described servomotor excitation and cut off described brake.
The present invention provides a kind of electric power saving control method of straight-bar machines in addition, for straight-bar machines is carried out to electric power saving control, at least one pair of needle-bar before and after described straight-bar machines possesses, by traversing use and be also used as the servomotor of servo brakes, make at least one party's needle-bar freely traversing along the length direction of needle-bar with respect to the opposing party's needle-bar, the pin of the cam carrier operation needle-bar by moving back and forth on described at least one pair of needle-bar and making knit fabric, straight-bar machines possesses brake, for forbidding the traversing of traversing needle-bar freely, the electric power saving control method of described straight-bar machines is carried out following steps: the weave data based on knitted fabric is obtained the sliding force that puts on traversing needle-bar freely from knitted fabric or cam carrier, below the sliding force of obtaining is the first setting and while not making shog by described servomotor, remove the excitation of described servomotor and described brake is connected, make shog in the time that the sliding force of obtaining exceedes the first setting and by described servomotor time, to described servomotor excitation and cut off described brake.
In the present invention, obtain the sliding force that puts on traversing needle-bar freely from knitted fabric or cam carrier.In addition in the present invention, to switch the braking based on servomotor or the braking based on other brakes in order differentiating, particularly can to utilize other brakes to press sliding force and prevent the careless movement of needle-bar in order to differentiate, obtain sliding force.The precision of the sliding force of therefore, obtaining is the degree that can carry out this differentiation.And below the sliding force of obtaining is the first setting and while not making shog by servomotor, if remove the excitation of servomotor and brake connected, can utilize brake braking time, remove the excitation of servomotor, can reduce power consumption.When sliding force exceedes the first setting in addition, and while making shog by servomotor, to servomotor excitation, brake is cut off, therefore the in the situation that of needs necessarily to servomotor excitation.And then switch servomotor or other brakes based on weave data, therefore can expect control in the future.That is, not only can differentiate at each time point that brake based on servomotor is suitable or other brakes are suitable, can also, to predicted conditions such as next process or next but one processes, therefore can more reasonably control.The switching of brake can also can be in process midway according to process unit, for example also can be in process sliding force be more than the first setting interval using servomotor as brake, other in process are interval uses the brakes beyond servomotors.
About obtaining sliding force, also can utilize the device beyond the straight-bar machines of knitting design system etc. by weave data.Whether the sliding force of obtaining is in addition below the first setting and whether makes shog by servomotor, also can obtain by knitting design system according to weave data.Therefore also can be by knitting design system, determine to use brake or other brakes based on servomotor, make straight-bar machines storage, by the output interface of straight-bar machines, switch brake and other brakes based on servomotor.
Described brake is preferably by switching on and cuts off, connect by the releasing of energising with the brake without excitation mode work.If like this, do not produce power consumption when brake is connected, can further realize electric power saving.
In addition preferably, also possess the sensor of the sliding force for measuring deformation gauge etc., described output interface is the excitation of more than the second setting forbidding removing servomotor at the sliding force of obtaining by described sensor, and brake is cut off.Can obtain the sliding force that acts on needle-bar according to weave data.But, if utilize the supervision such as deformation gauge to put on the power of needle-bar, can obtain the sliding force that puts on needle-bar in reality, in the time of the load producing outside imagination, also can tackle.Whether identical other the second setting is with the first setting all can.For example, when being thought of as control based on weave data and being principle, sensor-based control and being the security means of preparation, make the second setting be greater than the first setting.
Preferably, the pin number of described sliding force the calculating part gait of march based on cam carrier and needle selection on traversing needle-bar freely, obtains the sliding force that puts on needle-bar from cam carrier.The pin number of needle selection is more, puts on the more increase of power of needle-bar from cam carrier, and the gait of march of cam carrier is larger, puts on the more increase of power of needle-bar from cam carrier.Therefore can obtain sliding force by the pin number of the gait of march of cam carrier and needle selection.
Particularly preferably be, the needle gage number of described sliding force calculating part based on traversing shog freely and the radical across the stocking yarn between the needle-bar of front and back, obtain the sliding force that puts on needle-bar from knitted fabric.Radical across the stocking yarn between the needle-bar of front and back represents the degree needle-bar of front and back being linked mutually by stocking yarn, and traversing needle gage number represents that each yarn will make the power of shog.Therefore can be according to the needle gage number of traversing shog freely with across the radical of the stocking yarn between the needle-bar of front and back, obtain knitted fabric and make the power of shog.
In addition preferably, be provided with correction unit, by to servomotor excitation and when making knit fabric, compared with the sliding force that utilizes sliding force calculating part to be obtained by weave data by the value of exciting current of servomotor or the sliding force of the output torque detection of servomotor, differ defined terms when above compared with the sliding force of being obtained by weave data at the sliding force of measuring, change the first setting.
When starting, in the colder situation of straight-bar machines, the sliding force larger than the sliding force of being obtained by weave data acts on needle-bar sometimes.The needle tray that stays in straight-bar machines at dust in addition, the sliding force larger than the sliding force of being obtained by weave data acts on needle-bar sometimes.On the contrary start from braiding through long-time and straight-bar machines is warmmer, needle tray cleaned clean in the situation that, sometimes only have the sliding force effect less than the sliding force of being obtained by weave data.
Therefore for example in the time that braiding starts in 1～2 process left and right to servomotor excitation, for example, with maximum needle selection number braiding, mensuration puts on the sliding force of servomotor from needle-bar during this period.Even if the speed of cam carrier is during this period for example certain, also can between several speed, change.The sliding force that puts on needle-bar can be by the output torque detection of the value of the exciting current of servomotor or servomotor.And the ratio of the sliding force of for example obtaining the sliding force of mensuration and calculated by weave data or poor, at this than departing from defined terms above in the situation that from 1, or poor absolute value departs from situation more than defined terms, change first setting relevant with the sliding force of obtaining from weave data.In for example, more than the large defined terms of sliding force that the ratio of sliding force of measuring is obtained by weave data situation, reduce the first setting.

Detailed description of the invention
Below represent the optimum embodiment for carrying out an invention.Scope of the present invention should add the possibility of the change based on known techniques and make an explanation in the record of claim.
[embodiment]
In Fig. 1～Fig. 4, represent the straight-bar machines 2 of embodiment.In Fig. 1, the 4th, front needle-bar, the 6th, rear needle-bar, possesses respectively a large amount of knitting needles, between needle-bar 4,6, has tooth mouth 8.Herein, needle-bar 6 is freely traversing to the left and right directions of Fig. 1, and front needle-bar 4 is fixing, but also can be freely traversing together.Before and after upper and lower, possess in addition in the straight-bar machines of four needle-bars etc. of the needle-bar of needle-bar or barring-on portion material and also can be suitable for the present invention.In this situation, by before and after 4 needle-bars etc. separately, before and after making, a side 2 needle-bars etc. are traversing.
Cam carrier 10 moves back and forth to the left and right of Fig. 1 on needle-bar 4,6, and this stroke of 1 time is called to 1 process or 1 braiding process.Cam carrier 10 is selected the pin of needle-bar 4,6, and utilizes the pin of the pin of triangle control selection call in person and operate.Now, from cam carrier 10, via pin, sliding force acts on rear needle-bar 6.The 12nd, toothed belt, is driven the servomotor of use to drive by not shown cam carrier, and the 14th, the servomotor of traversing use, also uses as servo brakes, makes rear needle-bar 6 traversing.The 15th, measure the sensor of sliding force, the deformation gauge for example arranging at the axle of needle-bar or servomotor etc.While using deformation gauge as sensor 15, even if also can obtain sliding force in the time that servomotor cuts off.In addition as sensor 15, also can be to monitor the current sensor of value of the exciting current of servomotor 14 or the sensor of the output torque of mensuration servomotor 14, if but the load from weave data applies imagination can not be corresponding in the time that servomotor cuts off.
The 16th, brake, is using the type as brake work without excitation mode, by the effect of excitation brake off device.Represent the structure of brake 16 in the lower-left of Fig. 1.The 20th, axle, is carved with not shown screw thread at central portion, engages with the nut of being located at rear needle-bar 6, and while utilizing servomotor 14 that axle 20 is rotated, rear needle-bar is traversing to the left and right.The 22nd, brake disc, the 24th, exciting coil, the 26th, spring, the 27th, friction plate, during to coil 24 excitation, friction plate 27 overcomes the repulsion of spring 26 and separates brake off device from brake disc 22.While making to stop to the energising of coil 24, friction plate 27 is by repulsion and brake disc 22 crimping of spring 26, and brake is connected.Therefore the power consumption while not having brake to connect, power consumption in the time that brake is removed.
The control part 18 of straight-bar machines is stored weave data and resolves, the control signal of needle selecting device and triangle etc. on mobile control signal, the cam carrier of the control signal of output servomotor 14, the control signal of brake 16, cam carrier.The electric power saving control part 30 of embodiment is located in control part 18.
In Fig. 2,30 is electric power saving control part, and 32 utilize the weave data of weave data storage portion stores knitted fabric, and they are positioned at control part 18.Weave data analysis unit 34 carrying out each Cheng Qian parsing weave data that wove, for example, before braiding starts, is first read in and is resolved whole braiding process.Even the object of resolving have the rear needle-bar 6 of traversing state with respect to front needle-bar 4 with the quantity of the amount of several needle gages traversing, the stocking yarn transition of which direction to the left and right, across the radical of the stocking yarn between the needle-bar of front and back etc.Needle gage is the interval between the pin on needle-bar.For example storage forms traversing state between the needle-bar of front and back of time point of coil as traversing state originally in addition, but also can ignore these data.And obtained the loop length of coil by weave data, store if necessary material, the thickness etc. of stocking yarn as the data beyond weave data.These data are stored in storage part 36.
Correction unit 47 by the sliding force of being obtained by weave data and to servomotor 14 excitations and when making knit fabric, compared by the value of exciting current of servomotor 14 or the sliding force of the output torque detection of servomotor, differ defined terms when above at the sliding force of measuring and the sliding force obtained by weave data, change the first setting, and storage the first setting after changing.
The in the situation that in the time of starting, straight-bar machines 2 being colder, the sliding force larger than the sliding force of being obtained by weave data acts on rear needle-bar 6 sometimes.The needle tray that stays in straight-bar machines 2 at dust in addition, the sliding force larger than the sliding force of being obtained by weave data acts on rear needle-bar 6 sometimes.On the contrary start from braiding through long-time and straight-bar machines 2 is warmmer, needle tray cleaned clean in the situation that, sometimes only have the sliding force effect less than the sliding force of being obtained by weave data.
Therefore for example in the time that braiding starts with 1～2 process left and right to servomotor excitation, for example weave with maximum needle selection number, measure during this period the sliding force that puts on servomotor from needle-bar.Even if the speed of cam carrier is during this period for example certain, also can between several speed, change.This braiding does not need each knitted fabric to weave in addition, for example, in the time starting working every day etc., for straight-bar machines 2 can be woven according to the coil of the size of weave data, with adjust cam carrier 10 triangle " loop length routine " simultaneously.The sliding force that puts on rear needle-bar 6 can be by the output torque detection of the value of the exciting current of servomotor 14 or servomotor 14.In addition, to put on the sliding force of servomotor and while weaving in order measuring from knitting needle in the time that braiding starts etc., also can not use stocking yarn and the sky braiding that only makes pin move up and down.
The ratio of the sliding force of obtaining the sliding force of mensuration and calculated by weave data or poor, at this, than departing from rated condition when above from 1, or poor absolute value departs from rated condition when above, changes first setting relevant with the sliding force of being obtained by weave data.For example, when the large rated condition of sliding force obtained by weave data of ratio of sliding force measured is above, reduce the first setting.In the time that little defined terms is above, also can increase the first setting on the contrary, also can not change in addition the first setting.
The storage key element relevant with the sliding force of needle-bar 6 from cam carrier 10 acts in storage part 38.As this key element, have from pin number and the speed of cam carrier etc. of rear needle-bar 6 needle selections.Sliding force is will make the traversing power of rear needle-bar 6 along left and right directions, has the power that acts on from cam carrier 10 and the power from knitted fabric effect.Traversing by rear needle-bar 6, coil is compared position while formation when traversing to the left and right, from stocking yarn backward needle-bar 6 effects have sliding force.About this power, stronger across more this power of quantity of the stocking yarn between the needle-bar 4,6 of front and back, compare in addition and form coil when coil traversing distance (quantity of needle gage) is stronger to the left and right.And high according to the tension force of the less stocking yarn of the loop length of coil, material is thick and stiff etc. also can grow.In addition while replacing to form coil, be the traversing distance of benchmark, also can only use current traversing distance.Sliding force calculating part 40,42 becomes the sliding force from knitted fabric by suitable table, mapping, function etc. by these data transformations.
Sliding force calculating part 42, according to the gait of march of cam carrier and described pin number, calculates the sliding force of needle-bar from cam carrier 10 is applied to.Be the pin heel that cam carrier utilizes triangle control pin, this hour hands heel presses on cam carrier 10 and produces sliding force., start from the little state of the impact of cam carrier (cam carrier reversion or carry out the pin of needle selection few), to when inweaving portion etc. and select the state transitions of multiple pins, sliding force acts on sharp herein, therefore sometimes after needle-bar 6 traversing.Equally in process midway, even if the pin of selecting is counted cataclysm, also effect has sliding force.The gait of march of cam carrier is larger, and these sliding forces are larger.Traversing command storage unit 44 is stored having or not of traversing instruction.
Detection unit 46 carries out additional calculation to the sliding force of being obtained by sliding force calculating part 40,42.In addition sliding force has direction.In each 1～2 process of carrying out traversing process and front and back thereof, unconditionally make servomotor 14 connect, brake 16 is cut off.Be below the first setting and carry out, in the process beyond 1～2 process of traversing process and front and back thereof, making servomotor 14 cut off (releasing excitation) at the sliding force being added, make brake 16 connect (this also removes excitation).In addition the first setting uses and proofreaies and correct complete value in correction unit 47.Like this, taking process as unit, in storage part 48, storage makes which connection in servomotor 14 or brake 16.
Output interface 50 monitors the situation of carrying out of braiding, in for example 1 mistake Cheng Qian of carrying out each process, from storage part 48 sense datas, if the sliding force of being obtained by sensor 15 is below the second setting, according to the Data Control servomotor 14 of storage part 48 and brake 16.If sliding force exceedes the second setting, after needle-bar 6 in carry out traversing during, or make rear needle-bar 6 traversing power absent-mindedly because certain reason is applied with, therefore make in the latter case servomotor 14 connect, and brake 16 cut off.
In step 1～step 4 of Fig. 3, represent by the method for needle-bar 6 after cam carrier 10 pushings.Cam carrier reversion and while starting needle selection, the pin heel of pin is operated and presses by cam carrier, sliding force effect.This power with to inweave the pin number operating by cam carrier 10 in portion proportional.Another extrinsic process midway, in the time that the length of regulation changes the pin number of needle selection, to the proportional sliding force effect of variation of pin number.
In Fig. 4, represent from the mechanism of the sliding force of knitted fabric effect.The 52nd, before and after the transition yarn of 4,6 of needle-bars, the 54th, the coil of front needle-bar 4, the 55th, the coil of rear needle-bar 6.Fig. 4 coil 55 is observed traversing to the right in the past, by the tension force of yarn, makes rear needle-bar 6 to the traversing power effect in the left side of Fig. 4.The radical of this power and transition yarn 52 is proportional, and with proportional from forming the traversing distance starting when coil 55, the loop length of coil 55 is shorter stronger.Therefore according to these factors, can calculate from the sliding force of knitted fabric effect.
Obtain in an embodiment following effect.
1), the in the situation that needle-bar 6 being traversing absent-mindedly after not worrying, servomotor 14 is cut off, the excitation of brake off device 15, thus realize electric power saving.
2), by weave data, can obtain the switch data of servomotor 14 and brake 16 in advance.
3) from sensor 15 obtain practical function in the sliding force of needle-bar, in the time that sliding force is large, make servomotor 14 connect.
