Description

Produce the circular jersey knitting machine of pluse cloth

Technical field

The present invention relates to produce the circular jersey knitting machine of pluse cloth, this knitting machine is made of at least one knitting system, this knitting system comprises has an abdomen and that holds bottom line to hold the radially movable sinker of the nose of plush thread on it, these sinkers are controlled by cam, comprise locking pin cam radially and/or radially the locking pin cam each several part and at the radially movable stretcher of the plush loops of tensioning plush loops when radial motion is done at the knitting machine center, the sinker nose is in inserting original plush loops that forms when sinker is pulled out at the knitting machine center, and this knitting machine further comprises and being arranged in the syringe, knitting device by the control of the cylinder cam system of lifting that comprises a cam path and drop-down part.

Background technology

Produce the principle of knitting machine of pluse cloth known have multiple.What relate to here is the monolateral knitting machine that forms knitted fabric and plush loops with pin and special sinkers.For example known have a kind of principle, knitted fabric is formed on the sinker abdomen of two-faced machine as is known in this principle, and plush loops is formed on to be arranged in to be had pair plush loops tuck, plush thread and bottom line are correctly held on the sinker nose of inclined protrusions of pin on sinker abdomen top, the end face.The problem of this principle is that the length of very difficult generation uniform fabric, particularly plush loops is different in size.

It is also known for a kind of principle of in a groove, using two sinkers, it is also known for other irrelevant with theme of the present invention, as not constitute background technology of the present invention principle in addition.

In addition, it is also known for a kind of principle, referring to ES 459450 (with United States Patent (USP) 4,194,374 and 4,346,572).According to this principle, use the pin in the syringe and use the generation of the sinker in radial groove pluse cloth on the sinker bed.In this embodiment, on the yarn feeding position, sinker is pulling down to the limit from knitting machine center outward direction, so plush thread surrounds on the sinker nose, and bottom line surrounds on the sinker abdomen, and the sinker abdomen is provided with an inclined-plane climbs in the pinhock bottom line.The sinker of this original position is pulled out described bed to machine axis diametrically and is entered the kinking position and continue kinking in the described position of inclined-plane under pinhock that is used for bottom line is creeped.Tensioning plush loops then, use the projection on the sinker end face to pull out sinker, when pin is positioned at the highest raised position above backshank closed plush loops.Knit goods gos deep in the sinker larynx between sinker abdomen and the sinker nose when pulling out sinker, and the sinker nose inserts in original plush loops that forms simultaneously, is aligned in so once more on the same diameter.Can produce the knit goods very uniformly that is difficult to produce by another principle like this.The motion of pin is realized that by a cylinder cam system motion of sinker is realized by the camming of control sinker.These cammings and yarn held in the pin and sinker in being arranged in the actual knitting machine of guiding piece be known.

Fixedly connected with needle cam with one, the top has the stationary cam of a needle cam supporter that sinker is pulled down to original position, the needle cam cover is obliquely installed around the sinker bed.At first the stationary cam in the heel is pulled out to the kinking position to sinker forward from the drop-down position of maximum before the sinker by acting on, and stops the motion of sinker in this position.Pull out sinker with a plush loops stretcher then, the part of this stretcher is an active pointer cam, this active pointer cam rotates around the adjustment cam that is arranged on the pin in the needle cam with one when knitting machine is regulated, and this active pointer cam is on the sinker heel curre and pull out sinker with the tensioning plush loops.Two projections are arranged on this stretcher, and first projection is carried out tensioning above pinhock or pin chest, and second projection is carried out tensioning above backshank.Be next stationary cam after the tensioned portion of this movable cam, the original position of kinking in drawing under the sinker, this cycle carries out repeatedly by heel curre.With the motion of the synchronized movement of sinker by camming control pin.The fixed part of this cam rises to tension position to pin, one hole of transmitting plush thread is arranged in this position upward guide piece, the slowly drop-down pin from the maximum lift position simultaneously makes needle latch be covered by the line guiding piece and tensioning and plush thread can not come under the pinhock unintentionally.Pin pulls down to the position that is used for by the tuck in the book yarn very steeply then, with a pointed short arc it is risen to tuck position, and its ascending motion this moment stops, and pin leaves the cam fixed part in the horizontal direction.Drop-down inertia force can closed needle latch during at the plush thread tuck but very steep.Therefore the cam fixed part must long enough and the respective shapes of thread guides must make and make that it covers needle latch at this moment, prevent its tensioning.In addition, the guiding piece of this structure and camming require to use the sufficiently long pin of tensioning length to guarantee at the plush thread tuck, so cam length must be very long, and the knitting system quantity on the knitting machine must reduce.After leaving stationary cam, pin moves on on the movable draw-down cam, the pull-down section of this pin impact cam groove here, and carry out this kinking.

Then on the kinking position pin enter in the central cam of next stationary cam.

The major defect of such scheme especially is the structure of camming.By rotating cam is used as the plush loops stretcher, impact when not occurring over just the sinker heel curre and carrying out the transition to the very steep front end of plush loops stretcher but also occur in the sinker heel curre when stretcher carries out the transition to stationary cam, wherein the very steep rake of sinker two heel collision cam paths.So the many impacts that generate have limited the running speed of knitting machine.Another shortcoming of this embodiment is that the adjusting that changes stretcher also changes the position of this point, thereby pulls out sinker after the kinking again forward.In syringe system, change the position that kinking just changes this point then, thereby the beginning lift pins is bumped in the central cam in the pin heel.Relative position is changed like this, pin has promptly taken place begun to promote the change that begins the timing of tensioning translation with sinker and discharge old pile loop, closed bottom line simultaneously.Therefore need the delay of lengthening locational pin of kinking in, thus the needing length and cause the minimizing of the knitting system number on the knitting machine of lengthening camming.Because the structure of guiding piece, particularly owing to transmit the position in hole of plush thread so the knitting system number on the knitting machine further reduces, the free space that this need use longer cam fixed part and shorten draw-down cam, thus must do draw-down cam suddenly rather than transition gradually.The minimizing of knitting system number makes knitting machine productivity ratio descend.Another shortcoming of this embodiment is, central cam that each heel collision is very steep and draw-down cam cause in the syringe system impacts, and the bad result of all these is that the productivity ratio of running speed decline and knitting machine further descends.

The objective of the invention is to eliminate or alleviate at least these shortcomings of prior art.

The specific embodiment

Be example explanation the present invention with one single circular jersey knitting machine below, this knitting machine is installed on the frame with comprising the suitable method that illustrated since the supporter 1 of cylinder bed 2 supporters 1 this cylinder bed 2 and machine axis coaxial rotation.One cylinder bed 2 is arranged on the supporter 1 of cylinder bed 2, the bed 3 of a sinker 8 is arranged on the cylinder bed.Cylinder bed 2 is around the cyclinder needle cam support 4 that a coaxial setting is arranged, movable and stationary cam 5 or needle cam 52 are housed on the cyclinder needle cam, 51, cam 5 or needle cam 52,51 influence the heel 61 of pin 6 when cylinder bed 2 is rotated, thus the motion of control pin 6 on the direction parallel with machine axis.

Bed 3 tops and the machine axis of sinker 8 are provided with sinker 8 cammings coaxially, control the radial motion of sinkers 8 when the bed 3 of the sinker 8 that is connected with cylinder bed 2 rotates with sinker needle cam 9.

The sinker needle cam 9 of control sinker 8 comprises stationary cam radially and/or for example uses needle cam 7 and/or the supporter 10 of sinker needle cam 9 or the needle cam 91 and the radially activity plush loops stretcher 92 that needle cam 7 is fixedlyed connected of screw and sinker 8.

Needle cam supporter 10 is provided with around the bed 3 of sinker 8, and the needle cam 7 of sinker 8 is installed on its bottom surface in a preferred embodiment.

Plush loops stretcher 92 inserts the radially step 922 in the gap between the locking pin cam 91 and needle cam 7 at it near having on front of machine axis in a preferred embodiment.One projection 923 of aliging with radial groove in the needle cam 7 is arranged on plush loops stretcher 92 end faces.The bottom surface of the end face of the bed 3 of the close sinker 8 of plush loops stretcher 92 is provided with the cam path 924 of plush loops stretcher 92, its vertical walls affect sinker 8 heel curres 81, and control its radial motion.Plush loops stretcher 92 relative machine axis are radially regulated by set screw 925, and are resetted by spring 926.

The knitting of sinker 8 and pin 6 is known.

Find out this camming embodiment that controls sinker 8 from following to knowing the explanation of knitting machine function especially.Be explanation knitting machine function, Fig. 1 illustrates original position, and this moment, sinker 8 was moved to initial answer position downwards, promptly from the machine axis maximum distance position.Sinker 8 is pulled out by the part 911 of locking pin cam 91 radially and is entered the kinking position during from the running of this position knitting machine, and its radial motion here stops and by the part 912 of locking pin cam 91 radially sinker being remained on the stop position.Radially locking pin cam 91 directly forms a part of 913 at rear, kinking position on a close side of machine axis, by this part, by before sinker, acting on heel 82 the back, pull out sinker 8 than the gradient of the cam path subsequently of plush loops stretcher 92 littlely.

This part 913 is used for pressing down old pile loop and new bottom line 126 coils that form of tensioning.Be subjected to the gradient of the track 916 on its front end 921 of the ratio of slope of machine axis of track 915 of sinker 8 of this part 913 controls smooth at the plush loops stretcher.

When sinker 8 heel curres 81 contact stretchers 92 front ends 921, the control of sinker 8 is passed on the stretcher 92.The heel 81 of the radially motionless sinker 8 of stretcher 92 collisions, 82 o'clock, the sinker 8 that is drawn by the difference of the angle of the angle of part 913 and stretcher 92 front ends 921 is fallen the angle on the stretcher 92, because the gradient of transition part is regulated thereby reduced greatly than known configurations.Even the very big advantage of this embodiment is the change of the adjusting of plush loops stretcher 92 subsequently, do not change sinker 8 from pulling out that yarn kinking position begins yet.This makes the structure of cylinder cam system also can accurately control the tensioning of bottom line 126 and improve knitting quality.Beginning to pull out among this embodiment of sinker 8, beginning lift pins 6 after the yarn kinking, thereby keep the base fabric loop length constant, the tangential displacement of the camming of last available whole sinker 8 (around the displacement of machine axis) is cooperating between metering needle 6 and the sinker 8 when tensioning base fabric coil, and everything all is independent of the adjusting of plush suede stretcher 92.

In plush loops maximum tension district, stretcher 92 has at first above the chest of the hook of pin 6 and/or pin 6, then above the tail of pin 6 the tensioning projection of closed plush loops to 928,929.In another unshowned embodiment, stretcher 92 can be divided into two parts diametrically, with first and second parts, also available first tensioning projection 928 and the 929 independent regulation tensionings of the second tensioning projection.Form the rear end 927 of stretcher 92 then, retract the littlely drop-down gradually sinker 8 of the gradient of the drop-down position of initial maximum under these rear end 927 usefulness continue than drop-down sinker 8 in radially fixing needle cam 91 subsequently, sinker.In next camming, repeat this whole period of motion of sinker 8.The structure of cam path has also limited impact greatly at sinker 8 when stretcher 92 carries out the transition to next radially fixing needle cam 91, this moment sinker 8 heel collision next one locking pin cam 91 radially.

The motion of knitting hour hands 6 is by the cylinder cam system control that is provided for two each systems on the needle cam.Have on first needle cam 4 on needle cam 5, the second needle cams 4 that are called central cam 13 needle cam 5 that is called draw-down cam 14 is arranged.

Front end 131 that the gradient of central cam 13 is very flat and steeper subsequently lifting parts 134 upwards rise to extreme higher position on central cam 13 end faces 132 to pin 6, here the direction of motion of pin 6 changes, pin 6 is drop-down by the subsequent section 133 of central cam 13, it is steep that the gradient of part 133 begins the constant substantially subsequent section than central cam 13 simultaneously, therefore stop the drop-down of pin 6 by the more smooth arc 135 of the highest hoist point curvature of ratio of curvature pin, in the rear end that follows front end 141 closely 136 that carries out the transition to draw-down cam 14 of central cam 13, on tuck position, continue horizontal movement with the heel 61 of hour hands 6.Before the rear end 136 of central cam 13, stop pin 6 drop-down smooth curvature and be designed so that very big bounce does not take place in the heel 61 of pin 6 on the wall of central cam 13, so the heel 61 of pin 6 is left central cam 13 with horizontal movement substantially and entered draw-down cam 14.In this embodiment, need not to use longer horizontal component stabilization needle 6 in the prior art, therefore can shorten the length of camming greatly, improve the quantity of knitting system on the knitting machine.

Stopping gradually of pin 6 because thereon inertia force of effect is opened pin 6 tongues and stayed open and bounce-back and vibration do not take place, thereby the pin 6 that needle latch is opened bottom line 126 and plush thread 127 feeding knitting systems the time before the guide portion 12 of the guiding piece 11 of yarn 126,127 by and the guide portion 12 of needle latch collision thread guides 11 enter limit 121.But the top that stops the arc 135 of the drop-down cam path of pin 6 preferably be positioned at thread guides 11 guide portion 12 enter limit 121 front ends 122, after the terminal of this arc 135 is positioned at this top.Bottom line 126 is as is known in the larynx 85 of the hole 123 feeding sinkers 8 of ground warp vertical direction (promptly parallel with machine axis 3) in the guiding piece 11 of the present invention's structure like this, the inclined hole 124 of plush thread 127 through 123 the place aheads, hole of supply bottom line 126 be supplied and be output make this plush thread accurately import hook point than pin 6 low, than the high position of the nose 84 of sinker 8.But on guide portion 12 lateral surfaces (far away from pin 6) of guiding piece 11 projection 125 is arranged, this projection is preferably as the pin of elastomer 128 being introduced the larynx 85 of sinker 8.But elastomer 128 through being contained on the thread guides 11 the pulley supply and around above-mentioned projection 125 rotations and be fed into along thread guides 11 outsides in the larynx 85 of sinker 8 of hook below of pin 6.Use this embodiment of the invention in knit goods, can add elastomer 128 from one side with by plush thread 127 very well from another side, because these fiber 128 feedings are in the exact position that is used for correctly holding between the yarn 126,127 by bottom line 126.At Fig. 7 a, the projection of the groove 1250 that guiding elastomer 128 is arranged on it can be arranged on lateral surface of thread guides 11 in 7b illustrated embodiment.This projection 125 also can be other suitable components in not shown embodiment.

In draw-down cam 14, the heel 61 of pin 6 is driven on the steep slightly end face of draw-down cam 14 front ends 141 through the front end 141 of horizontal direction, and pin 6 is quickened to enter pull-down section 142 by the curvature subsequently of draw-down cam 14, and the kinking of traversing.In another not shown embodiment, there is two-sided width to be reduced to and the identical guide portion of pin 6 heel 61 width that an appropriate clearance is arranged on the front end 141 of draw-down cam 14.Draw-down cam 14 front ends 141 are followed by the part 142 that pin 6 is pulled down to kinking of draw-down cam 14.

On this position, do short stay at some back, the end pin 6 that reaches kinking 143, pin heel 61 enters the rear end 146 that lifting parts also arrives draw-down cam 14 then, pin 6 beginning here promotes with the gradient identical or more smooth with the gradient of camming central cam 13 rear ends 131 subsequently, thereby pin 6 heel 61 angles that drop on the central cam 13 reduce greatly, thereby the impact of pin 6 when draw-down cam 14 is transferred on the draw-down cam 13 also reduces greatly.Here a great advantages is, when changing kinking, puts 143 non-displacements, and pin 6 begins to promote against this point from this kinking, and these hour hands 6 are pulled out sinker 8 again by the suitable part of the radially locking pin cam 91 of controlling sinker 8 motions after kinking.Inclined-plane in easy flights 86 closed new bottom line 126 coils that form on the abdomen 83 of sinker 8 keep its appropriate length to produce high-quality knit goods like this.

In this embodiment of knitting machine of the present invention, can use known central authorities control pin 6 sinking depths.But the needle cam 4 of cylinder cam system is contained on cyclinder needle cam 4 supporters 41, and its position on the machine axis direction is controlled in known mode by the sinking depth central control unit.Change the position and the kinking in all systems of all draw-down cam 14 so simultaneously.For the tensioning plush loops, must be when changing central kinking and regulate in the tensioning process pin 6 remain unchanged according to the high position of sinker 8.Therefore, the needle cam 5 of the cylinder cam system that is made of the cam path lifting parts, the central cam 13 usefulness jockeys that promptly are installed in place on the parts 42 on the cyclinder needle cam 4 that moves along the machine axis direction are connected with the cam of cam support 10 or sinker 8 cammings.Use disc spring 46 and screw 45 these jockeys on sinker 8 needle cams 7 supporters 10 bottom surfaces to be made of an arm 44 in a preferred embodiment, this arm 44 is supported face 47 and presses down on the one end.One groove 441 is arranged on the other end of arm 44, and a clutch disk 421 that is fixed with on it on parts 42 tops of central cam 13 of pin 6 inserts in this groove along the direction parallel with machine shaft.According to the position of sinker 8 these parts 42 on the machine axis direction, with the invariant position of the central cam 13 of hour hands 6, the central cam 13 of pin 6 moves relative to sinker 8 and draw-down cam 14 according to the motion of cyclinder needle cam 4 supporters 41.If the central cam 13 of pin 6 begins to stop to limit the motion according to draw-down cam 14 during this moves, surpass linking arm and be depressed into the deflection that spring strength on sinker 8 needle cams 7 supporters 10 causes the end of the linking arm 44 that is connected with clutch disk 421, thereby prevent the knitting machine parts damages.
