The links-links circular knitting machine that is used for hosiery or analog generally includes bottom cylinder and top cylinder, bottom cylinder has vertical axis, and top cylinder is arranged on bottom cylinder top and coaxial with bottom cylinder, and these syringes can be actuated to each other and rotate around common axis rigidly.

A plurality of axial grooves are formed on the side of bottom cylinder and on the side of top cylinder.The axial groove of top cylinder is aimed at the axial groove of bottom cylinder.Sliding part is contained in each axial slots of bottom cylinder and in each axial slots of top cylinder.Between two syringes, promptly at knitting areas, a pin is arranged in each axial groove, this pin is provided with two ends or head, is respectively head portion and head portion; Can wish to form flat pin or purl according to people, thus with this pin move into bottom cylinder carry out with end it on knitting, thereby perhaps carry out available its lower end of this pin immigration top cylinder knitting.

Because pin does not have heel, so by being arranged on the sliding part in the bottom cylinder or activating pin by the sliding part that is arranged in the top cylinder, this depends on will form flat pin or purl.

The sliding part that uses at the links-links circular knitting machine that is used for hosiery or analog at present is made of the elongated sheets body usually, this elongated sheets body has first vertical side, and this first vertical side is designed to be positioned on the side that is formed on bottom cylinder or on the bottom of the axial groove on the side of top cylinder.

This sliding part also is provided with two heels, and these heels are spaced from each other along the longitudinal extension scope of sliding part, and laterally outstanding from second vertical side of sliding part, second vertical side opposite with first vertical side to.

These heels are used for producing sliding part along the moving of the corresponding axial groove of bottom cylinder or top cylinder, thus cause knitting machine various types of knitting in the pin that is associated with described sliding part of actuating, or pin is transferred to another syringe from a syringe.

Sliding part is in bottom cylinder or top cylinder according to sliding part on its first vertical side, promptly also being provided with hook-shaped lug towards holding sliding part that side in the bottom of wherein axial groove, this hook-shaped lug cooperates the head portion or the head portion of pin.

These pressing devices fix, be rigid attachment to cam box or supporting member, therefore need not the actuator of any operation usefulness.

Connection Element actuating cam 9,9 ' between, be provided with mainly be designed to activate Connection Element 4,4 ' and sliding

part

3,3 therefore ' cam, thereby pin 6 is transferred to another syringe from a syringe.

Specifically, following cam is set: fixing top reduces cam 51, and this top reduces cam 51 can be set at Connection Element 4 ' cooperation in the top cylinder, thereby causes sliding part 3 ' the be reduced to position that is used to cooperate respective needle 6; And bottom lift cam 52, this bottom lift cam 52 can be connected element 4 and cooperate, thereby sliding part 3 is risen to and cooperates respective needle 6 corresponding positions.

Top reduces stationary cam 51 and bottom and promotes stationary cam 52 is arranged on selected element 23 with respect to the rotation direction 35 of cam box around himself axis along syringe upstream.

Along rotation direction 35, reduce the downstream that stationary cam 51 and bottom promote stationary cam 52 on top, shown in be provided with pressing device between cam and the selected element 23, be respectively upper closure presser 53 and lower closure presser 54, sliding part 3 ' can cooperate these pressing devices respectively with sliding part 3, sliding part 3 ' can be in the state that it is swung away from the bottom of corresponding axial groove 2 with sliding part 3, and can match with the head portion 6a ' and the head portion 6a of respective needle 6 in its end.

What aim at substantially with selecting arrangement 23 is that pressing device 55 is opened on top, this top open pressing device 55 towards the side of top cylinder and be equipped with Connection Element 4 in top cylinder ' heel 4b, thereby cause sliding part 3 ' swing, with sliding part 3 ' the move apart bottom of corresponding axial groove 2 towards the end of respective needle 6.

Once more along the rotation direction shown in the arrow 35, downstream at selected element 23, the side of bottom cylinder 1 faces toward and reduces stationary cam 56, this bottom reduces stationary cam 56 can be connected to exclusiveness element 4 cooperations, and this Connection Element 4 is arranged in the bottom cylinder 1 and has made its movable heel 4a move to the operating position by described selecting arrangement 23.

Along rotation direction 35, after bottom reduction stationary cam 56 has just started, the side of top cylinder is towards upper closure presser 57, this upper closure presser 57 can be equipped with sliding part 3 in top cylinder ', thereby cause sliding part 3 ' swing, with sliding part 3 ' the shift to bottom of corresponding axial groove 2 towards the end of respective needle 6.

Along rotation direction 35, after the bottom reduces stationary cam 56, the side of bottom cylinder faces toward and opens pressing device 58, the heel 4b cooperation that pressing device 58 can be connected to exclusiveness element 4 is opened in this bottom, this Connection Element 4 is arranged in the bottom cylinder and makes its movable heel 4a be in the non-operative position, promptly mismatches the bottom and reduces stationary cam 56.The bottom is opened pressing device 58 and is designed to cause sliding part 3 swings that cooperate it, thereby sliding part 3 is moved apart the bottom of corresponding axial groove 2 towards the end of respective needle 6.

At last, once more along rotation direction 35, open the downstream of pressing device 58 in the bottom, the side of top cylinder 42 promotes stationary cam 59 towards top, this top promote stationary cam 59 can be set at Connection Element 4 in the top cylinder ' heel 4a cooperate, and bottom cylinder faces toward and closes pressing device 60, this lower closure presser 60 can be cooperated by sliding part 3, thus with acted on it bottom open the sliding part 3 of pressing device 58 turn back to sliding part 3 towards the end of pin 6 position near the bottom of corresponding axial groove 2.

The cam set of the knitting machine among first embodiment is at least near the yarn feeding of knitting machine or doff, this cam set preferably can syringe 101 around himself axis 101a along in rotation direction 35 rotating process with at syringe 101 around himself axis 101a along presenting pin 106 in opposite rotation direction 36 rotating process, this cam set can be provided with to the slider actuation cams 8 that is limited by the dotted line among Fig. 4 to 7 150 mode similar with the part of Connection Element actuating cam 9, has corresponding selected

element

21,22 and

pressing device

62,63.

In two embodiment, belong to extraction cam and the withdrawal cam or the lift cam of Connection Element actuating cam and reduce cam and have the part that has profile, this profile phase tilts for the ideal plane, this ideal plane is perpendicular to syringe 1,42,101 axis 1a, 101a, these parts can be by the movable heel 4a in the operating position, 4a ', 104a cooperates, and extract element out by

selector

5,5 ', 105 act on Connection Element 4,4 ', on 104, extract the selected element that element is set in place the rake office of the one or more cams in described cam out, and constitute, thereby substantially in set corresponding extraction or withdrawal or lifting or reduce on the whole expanded range of sloping portion of cam with movable heel 4a by pressing device 40 or other pressing device, 4a ', 104a remains on the operating position.

Because like this, knitting machine according to the present invention guarantees highly precisely to activate pin, also is like this even syringe has very high actuation speed or has vibration around the rotation of its axis.

In a second embodiment, as follows according to the operation of knitting machine of the present invention.

Fig. 5 to 9 show the sliding

part

3,3 that is associated ' and Connection Element 4,4 ' the path that

heel

3a, 4a, 4b followed.

For with Connection Element 4,4 ' operating position and the non-operative position of heel 4a distinguish, the heel 4a that is in the operating position is decorated with shade, and the heel that is in the non-operative position does not have shade.

Usually or syringe commonly used in the rotation direction 35 of its axis with respect to cam box; when the pin 6 that cooperates in being in bottom cylinder 1, with sliding part 3 does not also form knitwear at the yarn feeding A that is considered; after the heel 4a that pressing device 62 may be in the Connection Element 4 of operating position moved to the non-operative position, the selecting arrangement or the pressing device that are arranged on selected element 21 places did not act on the selector 5.For this reason, Connection Element 4 cooperates withdrawal cam 32 without its heel 4a, so sliding part 3 no longer reduction after cooperating extraction cam 28 with its fixed heel 3a, and crosses central cam 26.Therefore pin 6 keeps rising in the non-operative position, and mismatches the yarn that distributes at the yarn feeding A place that is considered.

In the non-operative position, pin 6 is extracted out, make it be in a position from syringe 1 last terminal 6a up, in this position, if carry out knitting, then should go up terminal 6a and will be engaged in the yarn that yarn feeding A place distributes, and perhaps make terminal 6a be in the position that raises slightly, thus by the pin 6 previous any knitwear rings that form with on the shank that self is arranged on below the needle latch of pin 6.

Thereby prevent the selecting arrangement operation and reset the program of operation that this situation also can take place even should be noted that the knitting machine sudden power.In this case, the inefficacy of selecting arrangement can not cause any infringement for knitting machine, because no matter Connection Element 4 may be on which point in its path, when selecting failure of apparatus, if the heel 4a of Connection Element 4 is in the operating position, in case then it runs into pressing device, Connection Element 4 just makes its heel 4a move to the non-operative position, and therefore at the yarn feeding A place that is considered, its heel of sliding part 3 usefulness 3a crosses central cam 26, and no longer reduce, unless recover the operation of selecting arrangement.

When pin 6 is in the top cylinder 42 and with sliding part 3 ' when cooperating, similar described operation also can take place.Fig. 5 also show corresponding to the sliding part 3 that is arranged on the pin 6 in the top cylinder 42 ' fixed heel 3a and Connection Element 4 ' heel 4a, the path of 4b, this pin must not be moved to carry out knitting at the yarn feeding A place that is considered.

When must forming knitwear and syringe at the yarn feeding A place that considered, the pin in the bottom cylinder 16 is actuated to around himself axis with respect to cam box in rotational direction 35 when rotating, at corresponding Connection Element 4 (alternatively, make its movable heel 4a be in the operating position) forwarded pressing device 62 to, thereby with its movable heel 4a safe transfer after the non-operative position, by in the selecting arrangement of selected element 21 places setting or the intervention of pressing device, make heel 4a get back to the operating position.

Therefore, sliding part 3 is being drawn out of that cam 28 cooperates after promoting, because heel 4a reduces with withdrawing cooperating of cam 32.For this reason, the heel 3a of sliding part 3 cooperates central cam 26 and casting-off cam 29 therefore, as shown in Figure 6.Corresponding pin 6 cooperates with the yarn that distributes at the yarn feeding A place that is considered, and forms new knitwear ring, reduces the previous knitwear ring that forms.

On the contrary when with top cylinder 42 in the pin of sliding part 3 ' cooperate must carry out at the yarn feeding A place that is considered when knitting, forwarded pressing device 65 to corresponding Connection Element 4 ' (may make its movable heel 4a be in the operating position), thereby with its movable heel 4a safe transfer after the non-operative position, intervention by selecting arrangement or pressing device, make heel 4a get back to the operating position, this selecting arrangement or pressing device are towards the side of top cylinder 42 and be similar to selecting arrangement or the pressing device that is provided with at selected element 21 places.

Therefore, after sliding part 3 ' being drawn out of cam 28 ' cooperation promotes, because heel 4a reduces with withdrawing cooperating of cam 34.For this reason, sliding part 3 ' heel 3a cooperate casting-off cam 29 '.

Fig. 6 also show corresponding to the sliding part 3 that is arranged on the pin 6 in the top cylinder 42 ' fixed heel 3a and Connection Element 4 ' heel 4a, the path of 4b, this pin must be moved to carry out knitting at the yarn feeding A place that is considered.

Pin 6 in being arranged on bottom cylinder 1 must form knitwear and syringe and be actuated to around himself axis with respect to cam box in rotational direction 36 (this rotation direction with direction is opposite usually) when rotating, forwarded pressing device 63 at corresponding Connection Element 4 (may make its movable heel 4a be in the operating position), thereby with heel 4a safe transfer after the non-operative position, by in the selecting arrangement of selected element 22 places setting or the intervention of pressing device, make heel 4a get back to the operating position.

Therefore, sliding part 3 is drawn out of that cam 30 cooperates and after promoting at its heel 3a, because heel 4a reduces with withdrawing cooperating of cam 33.For this reason, the heel 3a of sliding part cooperates central cam 26 and casting-off cam 31 therefore, as shown in Figure 7.Corresponding pin 6 cooperates with the yarn that distributes at the yarn feeding A place that is considered, and forms new knitwear ring, reduces the previous knitwear ring that forms.

The yarn feeding A place that is being considered, in the process at the yarn feeding A place that considers passing through, also can produce tuck stitch by making the pin that must form tuck stitch transfer to the non-operative position simply, in follow-up transfer process, according to the rotation direction of syringe, cause that on the contrary the heel 3a of respective slide 3 cooperates with casting-off cam 29 or 31.In first transfer process, the previous knitwear ring that forms will self be arranged on the shank of needle latch below of pin 6, and another knitwear ring is shelved on the shank of pin 6.In second transfer process, the new knitwear ring that pin 6 forms, the knitwear ring that this is new and described two knitwear rings are knitted together, and they reduce simultaneously...

Like this, promptly use single yarn feeding or doff and also can form the tuck stitch knitwear.

By selecting

arrangement

21 and 22, also can reduce gradually and increase pin gradually implements knitting, these pins are moved to carry out knitting in the yarn feeding of being considered place, usually the device that is called hammer or pick-up and flap by use in the knitting machine of traditional type is realized knitting, thereby the present invention need not to adopt these devices.

When must be when a syringe be transferred to another syringe with pin 6, by being arranged on selected element 25 and beginning transfer operation towards the selecting arrangement at the corresponding selected element place of top cylinder 42, its move all

Connection Elements

4,4 of being arranged in bottom cylinder 1 and the top cylinder 42 ', so that its heel 4a is in the operating position, and syringe is actuated to along rotation direction 35 rotations, shown in Fig. 8 and 9.

Therefore the Connection Element 4 that is arranged in the bottom cylinder 1 cooperates the bottom to promote stationary cam 52 with its heel 4a, is arranged on Connection Element 4 in the top cylinder 42 ' with its heel 4a cooperation top reduction stationary cam 51.Connection Element 4,4 ' with cause cooperating of these cams 51 and 52 sliding part 3,3 that is arranged in top cylinder 42 and the bottom cylinder 1 ' approaching mutually, thereby cause that the hook-shaped lug 7 on corresponding heads 6a, the 6a ' of its longitudinal end and pin 6 overlaps.For this reason, the previous sliding part 3,3 that does not also cooperate with respective needle 6 ', because the special shape of hook-shaped lug 7 and its corresponding heads 6a, the slip on the 6a ' at pin 6, stand swing on the sagittal plane, this swing causes that hook-shaped lug 7 moves apart and holds sliding part 3,3 ' in the bottom of wherein corresponding axial groove 2.Then, the sliding part that has stood this swing cooperates lower closure presser 54 or upper closure presser 53, pressing device cause along sliding part 3,3 ' the opposite direction swing, thereby cause that it cooperates with corresponding heads 6a, the 6a ' of pin.Like this, pin 6 is by sliding part 3 and sliding part 3 ' cooperation simultaneously.

This moment, by selecting arrangement that is arranged on selected element 23 or pressing device, just selected pin 6 to be transferred to from bottom cylinder 1 Connection Element 4 of top cylinder 42.In next-door neighbour the place ahead of selected element 23, pressing device 61 makes the heel 4a of the Connection Element 4 that is arranged in the bottom cylinder 1 transfer to the non-operative position.Selecting arrangement 23 acts on the Connection Element 4 that is arranged at bottom cylinder 1 and is connected to sliding part 3, this sliding part 3 must keep cooperating with respective needle 6, thereby it is knitting to carry out to move described pin 6 in bottom cylinder 1, causes its heel 4a is transferred to the operating position from the non-operative position.

Select operation simultaneously basic with this, the sliding part 31 that is arranged in the top cylinder 42 stands the action that pressing device 55 is opened on top, causes all sliding parts 3 of being arranged in the top cylinder 42 ' move apart along its hook-shaped lug 7 direction swing of the bottom of corresponding axial groove 2.

Moved to the heel 4a operating position, that be arranged on the Connection Element 4 in the bottom cylinder 1 and therefore cooperated the bottom to reduce stationary cam 56, caused that it reduces, and therefore is entrained in the pin 6 that is mated in the bottom cylinder 1.In case this reduction campaign beginning is arranged on sliding part 3 in the top cylinder 42 ' just run into upper closure presser 57, cause sliding part 3 ' along the direction swing of the bottom of its engagement lugs 7 being shifted to corresponding axial groove 2, as shown in Figure 8.Because corresponding Connection Element 4 reduces cooperating of stationary cam 56 with the bottom, this swing is for the not influence of pin that has begun to reduce this moment in the bottom cylinder 1, but determine sliding part 3 ' hook-shaped lug 7 cooperate with the new of respective needle, it is set at sliding part 3 in the bottom cylinder 1, that also do not cooperate with its heel and bottom reduction stationary cam 56 and cooperates.

Therefore running into the bottom opens pressing device 58 also not cooperate the bottom to reduce the sliding part 3 of stationary cam 56, causes it along making hook-shaped lug 7 move apart the direction swing of corresponding axial groove 2 bottoms, thereby the head portion 6a that causes these sliding parts 3 and respective needle 6 throws off.

Be arranged on Connection Element 4 in the top cylinder 42 ' therefore cooperate top lifting stationary cam 59 with its heel 4a, this top promotes stationary cam 59 and causes Connection Element 4 ' move up and therefore be arranged on moving up of respective needle in the top cylinder 42, this pin is thrown off with the sliding part 3 that is arranged in the bottom cylinder 1, as shown in Figure 9.

This moment, finish the transfer of pin from a syringe to another syringe, and be arranged on sliding part 3 in the bottom cylinder 1, that be connected to Connection Element 4 (having made heel 4b and bottom open pressing device 58 cooperates) by with the swing in opposite direction that cooperates once more of another lower closure presser 60, the face down side of syringe 1 of this lower closure presser 60.

The operation of the knitting machine among first embodiment with for referring to the knitting machine among second embodiment, do not form knitting and form knitting described class of operation seemingly with the pin that is arranged in the bottom cylinder 101, and can be referring to shown in Fig. 5 to 7, difference is, actuating cam 8 does not limit the path of the fixed heel 3a of sliding part 3, but limits the path of the fixed heel 103a of pin 106.

In fact, have been found that, knitting machine according to the present invention can be completely achieved its intended purposes, because its allow to reduce even exempt the movable cam in the cam set that is provided with around syringe, but can realize all knitting kinds that the circular knitting machine that is used for hosiery or analog of traditional type can be implemented at present basically.

Another advantage according to knitting machine of the present invention is, it is guaranteed even in the high speed of service with there is accurate operation under the vibration situation.
