The specific embodiment

With reference to the accompanying drawings, Reference numeral 1 generally refers to the knitting footwear machine of circle according to the present invention.For clearer, in Fig. 1, omitted the some parts relevant with the structure of this machine.

Machine 1 comprises syringe 10, is making a plurality of longitudinal grooves on the outer surface of this syringe 10 or on the shell, and pin 12 slides along these longitudinal grooves.According to a kind of embodiment, pin 12 is upwards promoted by pillar 16 or needle selection device, if necessary is plugged with intermediary element 17 betwixt.

Pin 12 is provided with pinhock 13 and relevant tongue piece 13 ' at the top, and is provided with coil holding device in the position far below these.For example, described coil holding device comprises shoulder or the projection 14 that substantial horizontal is extended.Advantageously, be close to this shoulder 14 below, each needle set is fluted 15, thereby allows inner drift to link to each other with outside drift with the formation transfer stitch.

Needle selection device 16 is equipped with recess, and this recess can engage with the panel 18 of the needle selection device actuator 19 of equal number, and described panel 18 is activated separately according to pattern to be formed.

Above syringe 10 and be eccentric in syringe 10, the dials 20 that is essentially circular is installed, it is engaged in the rotating shaft 21 of itself.Be provided with a plurality of grooves on the upper surface of dials 20, these grooves accommodate inner drift 22 slidably.Advantageously, described groove is not to be arranged in the radial direction just, but suitably tilts along the direction opposite with direction of rotation, thereby constitutes the big envelope of circumference.This layout allows reliable functioning more, because it has determined the gradient of inner drift, this gradient is particularly conducive to when lifting coil, inserts the needle in the concave indentation 15.

Inner drift 22 is provided with the designated bossing 23 that is used for being bonded on corresponding needle track 24, and this needle track 24 is formed on the lid 25 of dials 20.Described needle track is equipped with panel 26,26 ', the leaving and returning of this panel 26, the described inner drift 22 of 26 ' control (Fig. 3).

Be eccentric in this syringe, attached plunger carrier hat 30 is installed, but it have the eccentricity opposite with the eccentricity of this dials on the same plane that limits by dials 20.The outside drift 31 that is provided with bossing 32 radially slides along the needle track 33 of the correspondence on the lid 34 that is arranged on attached hat 30, and this bossing 32 is designated to be used for being bonded on this corresponding needle track 33.Described needle track 33 is provided with panel, and this panel is controlled the footpath of described outside drift 31 and marched forward and withdraw.

Syringe 1 has the sinker support hat 40 that has radial groove in top-supported, is placed with sinker 42 in these radial grooves so that slip sinker 42.

Circular machine 1 is equipped with the electronic needle selecting apparatus 45 that at least one is used to select sinker 42, and this electronic needle selecting apparatus 45 can be controlled each independent sinker advancing radially, as will be described hereinafter.Each sinker has at least one needle selection device heel 43.Electronic actuators is equipped with the identical needle selection apparatus or the slide plate 46 of quantity of the needle selection device heel of quantity and sinker.Each needle selection apparatus can drive electronically, goes up and make its center radial displacement towards syringe with each heel that acts on sinker.

Advantageously, there are at least three, are preferably four needle selection device heels, and therefore have four needle selection device slide plates, to guarantee during the rotation of this syringe, correctly and reliably selecting each sinker.Obviously, during use, each sinker 42 has independent needle selection device heel 43, and adjacent sinker is positioned over different height places with their heels separately.

In other words, it is the individual drive unit 46 of N that the electronic needle selecting apparatus 45 of sinker is equipped with quantity, and its shape that is comb is vertically stacked each other, can optionally be activated.This sinker is equipped with single needle selection device heel 43, so that N adjacent sinker is presented in the differing heights place with their heels separately, these height are corresponding with the position of N drive unit 46.

Each sinker 42 is provided with barring-on plane 47 to form plain loop or transfer stitch (when not selecting this sinker), and be provided with top beak shape thing 48 to form the looped pile coil, perhaps as forming the transfer stitch (when selection is arranged in the sinker of forward location) that has than macropore in explanation after a while like that.

In addition, each sinker has top teat 49, and this top teat 49 is controlled by relevant panel, and has determined the normal radial displacement of this sinker.

Syringe 1, dials 20 and attached hat 30 are with identical rotating speed and along identical direction rotation.According to a kind of embodiment, their rotation is by the single motor unit controls.For example, Fig. 3 shows the gear 50 that transfers the motion to the attached hat 30 of outside plunger carrier.According to a kind of embodiment modification, dials or outside hat need not inevitable by gear control, but can be driven and by powering with itself actuator of main motor synchronous by motor independently.

The result, when syringe being made for toothed portion when rotation arranged by what be located at its lower end, attached hat 30 receives its motion from the main shaft of aforesaid gears, simultaneously, the dials 20 that supports by relevant central shaft 21 again by means of other gear or with the independently motor rotation of main motor synchronous.

Fig. 3 also shows the center 10 ' of syringe disconnected from each other, the center 24 ' of dials needle track 24 and the center 30 ' of attached hat 30.

Fig. 4 shows the main yarn of seeing from the top and supplies with thread-carrier 54, and as the embodiment example, shows other thread-carrier 57 that is used to supply with the thread-carrier of ELASTANE YARNS 56 and is used for coloured yarn.

As from the view Fig. 4 as can be seen, this machine can be divided into three independently workspaces basically, each workspace is wide approximately 120 °.From main yarn drainage area or doff the district the position, the first district A that is provided with electronics sinker needle selection apparatus 45 is used to select to form the looped pile coil or the sinker of the transfer stitch widened, the second district B subsequently that is provided with the actuator needle selection apparatus of pin 19 is used to carry this coil and therefore by lifting the district and the district of doffing is delimited, and the 3rd district C subsequently is used for any other operation such as being inserted with dyed yarn line and/or cotton thread or so-called hand pick or restricted yarn.

In regional A, the function of this machine is as follows.

If digitalized needle selecting machine actuator and non-selected sinker 42 then normally form plain loop or transfer stitch, each yarn of being given by main thread-carrier 54 all drops on the barring-on plane 47 of sinker.

In order to select the sinker of requirement, before the sinker that the processor unit of programming based on the style of these article optionally instructs in drive unit or the slide plate 46 to have heel 43 in the position corresponding with described control body arrives, will itself be positioned in the position of interfering with described heel.Have the back sinker of selector heel with the differing heights place of last sinker will be selected by corresponding different driving device, these drive units are activated by this processor.

Selected thus sinker occupies forward location, in this position, in first thread-carrier 60 that at least one is used for main yarn 61 and second thread-carrier, 62 (see figure 7)s that at least one is used for loopy yarn 63 in advance suitably behind the location, main yarn 61 is shelved on the barring-on plane 47, and loopy yarn 63 is shelved in the top beak shape portion 48 of sinker 42.Thus, in delegation, formed the looped pile coil of the coil that is used for required and predetermined number.

Should be noted in the discussion above that therefore the formation of looped pile coil be totally independent of the selection of pin.Obviously, above-mentioned selection step makes even utilizes the different feeds on the same line circle to realize that same looped pile style becomes possibility.

According to a kind of embodiment modification, at least two thread-

carriers

60,62 of main charging 54 are arranged on sustained height place and close (Fig. 8) basically, thereby under the situation of having selected sinker, the yarn of all feedings is all dropped on the top beak shape thing 48 of these sinkers.In the area B subsequently of this machine, be used for transfer stitch if select with the corresponding pin of selected sinker, then form the transfer stitch that has than macropore, just, formation has the transfer stitch in the hole bigger than the situation of common appearance, and the width in this hole is determined by the height of the top beak shape thing of this sinker.

In order to achieve this end, can use special sinker 42 ', with the width (Fig. 8) in the hole of strengthening this transfer stitch with the top beak shape thing 48 ' that is higher than conventional sinker.

In the zone that refers to, is used for carrying coil by letter b of this machine, function following (Fig. 9 a to Fig. 9 d).

According to the style of these article, this processor instruction needle selection device actuator is promoted to the pin 12 of requirement far above normal operation height place highly, to form transfer stitch.During the starting stage, (be used to carry the district of lifting of coil, Fig. 9 a) promotes selected pin C to place this coil and this coil is kept being hooked in the shoulder that is arranged on each pin or other holding device 14 of coil.In this position, pin C utilizes horizontal cut himself to be arranged at the height place (depending on that this coil is to the right or is moved to the left) at inner drift or outside drift 31 places.Subsequently, this drift begins the motion of leaving of its level.When pin C did not temporarily work, drift will itself be inserted in this breach, and therefore same the insertion in this coil.Pin C reduces himself, thereby this coil is stayed (Fig. 9 b) in this drift.After pin C being reduced fully, because outside plunger carrier hat or dials be with respect to the skew of syringe, drift is towards next (or last) pin D displacement, and this next (or last) drift does not temporarily work.Pin D rises and himself is inserted in the coil of being carried by this drift (Fig. 9 c) subsequently.Pin D continues to rise, and this drift utilizes the return movement of level coil to be stayed (district of doffing of transfer stitch, Fig. 9 d) on the pinhock of pin D simultaneously.

Therefore, because dials causes these pins with respect to these drifts about pitch that staggers with respect to the degree of eccentricity of syringe, therefore, when the inside drift that uses for dials, this coil is transferred to previous pin along the direction of advancing from a pin.Vice versa, owing to there be the relative degree of eccentricity of hat with respect to syringe, therefore, when the outside drift that uses for this attached hat, coil moved to next pin from a pin.

Be passed to these drifts for the ease of coil from these pins, the breach 15 of pin 12 is formed by the laterally inclined lateral trench with respect to described pin.

Like this, in the area B of this machine,, coil or a plurality of coil can be transferred to previous or next pin from one or more pins respectively, can make that obtaining transfer stitch becomes possible operation by selecting these pins.

In a word, make the knitting technology weave that obtains following type become possibility according to machine of the present invention.

By the main thread-carrier of supplying with being set with formation looped pile coil and by selecting the pin that is used for transfer stitch required in sinker required among the regional A and the area B simply, we have formed looped pile coil and the transfer stitch that designs on same circular coil, just, along the circumference of these article that constitute by looped pile coil and transfer stitch under the situation that does not have any mechanical constraint, realized fully by designing institute to be formed exert one's influence staggered.

Supply with thread-carrier and be arranged side by side by leading in sustained height place basically, and by in sinker required among the regional A of simple selection and the area B with the corresponding pin that is used for transfer stitch of sinker that selected, we have formed the transfer stitch that has than macropore.

Same by in area B, selecting and the corresponding pin of unselected sinker, we are under the situation without any mechanical constraint power, on same circular coil, formed and have than the transfer stitch of macropore and have the transfer stitch in normal hole, and realized fully by style to be formed exert one's influence staggered.

Therefore, following coil staggered realization on same circular coil:

-jersey (unselected sinker and pin), looped pile coil that designs and transfer stitch (having normal hole);

-jersey (unselected sinker and pin), and have transfer stitch than macropore (only selecting and the corresponding pin of having selected of sinker);

-jersey (unselected sinker and pin) has the transfer stitch in normal hole, has the transfer stitch than macropore.

Figure 10 and Figure 11 show socks 70, two examples of 70 ', on these socks 70,70 ', on same tubular portion, can find out at least one zone that constitutes by coloured knitting knop cloth 71,71 ', at least one zone 72 that constitutes by transfer stitch, 72 ' (having normal hole) respectively, the zone 73 that constitutes by the substrate knop cloth and the zone 74 that constitutes by jersey.

Figure 12 more properly shows the part of a pair of Lingerie 80, goes up in this section, and the zone that is made of the transfer stitch that has normal hole 81 as can be seen on same tubular portion alternately occurs with the zone that is made of the transfer stitch that has than macropore 82.

Those skilled in the art can be when remaining in the protection domain of claims, and utilization modifies, changes and replace some element to satisfy accidental needs with other embodiment of the embodiment functional equivalent of this machine.For example, can use electromagnetic actuator to replace the pneumatosphere actuator.
