Specifically, following cam is set: fixing top reduces cam 51, and this top reduces cam 51 can be arranged on Connection Element 4 in the top cylinder ' cooperations, thereby causes sliding part 3 ' the be reduced to position for cooperation 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 the position corresponding with cooperating respective needle 6.
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, respectively upper closure presser 53 and lower closure presser 54, sliding part 3 ' can cooperate respectively these pressing devices 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 head portion 6a ' and the head portion 6a of respective needle 6 in its end.
What substantially aim at selecting arrangement 23 is that pressing device 55 is opened on top, this top open pressing device 55 facing up syringe the side and be equipped with Connection Element 4 in top cylinder ' heel 4b, thereby cause sliding part 3 ' swing, with sliding part 3 ' move apart towards the end of respective needle 6 bottom of corresponding axial groove 2.
Again 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 ' shift to towards the end of respective needle 6 bottom of corresponding axial groove 2.
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, namely mismatches the bottom and reduces stationary cam 56.The bottom is opened pressing device 58 and is designed to cause that the sliding part 3 that cooperates it swings, thereby sliding part 3 is moved apart the bottom of corresponding axial groove 2 towards the end of respective needle 6.
At last, again 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 arranged on 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 the sliding part 3 that has acted on the bottom on it and open 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 the first embodiment is at least near the yarn feeding of knitting machine or doff, this cam set preferably can be presented pin 106 at syringe 101 in the process that himself axis 101a rotates along opposite rotation direction 36 in the process that himself axis 101a rotates along a rotation direction 35 and at syringe 101, this cam set can arrange to the slider actuation cams 8 that is limited by the dotted line 150 among Fig. 4 to 7 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 the extraction cam of Connection Element actuating cam and retraction cam or lift cam and reduce cam and have part with profile, this profile tilts with respect to 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 arranged on the rake office of the one or more cams that are arranged in described cam out, and consisted of by pressing device 40 or other pressing device, thereby substantially in set corresponding extraction or retraction or lifting or reduce on the whole expanded range of sloping portion of cam movable heel 4a, 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 ' heel 3a, 4a, the path that 4b follows.
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.
At syringe usually or 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 considers; 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 retraction 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 considers.
In the non-operative position, pin 6 is extracted out, make it be in a position from syringe 1 upper terminal 6a up, in this position, if carry out knitting, then should will be engaged in the yarn that yarn feeding A place distributes by upper terminal 6a, and perhaps make terminal 6a be in the position that raises slightly, thereby any knitwear rings that before formed by pin 6 are 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 occur even should be noted that suddenly outage of knitting machine.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 considers, its heel of sliding part 3 usefulness 3a crosses central cam 26, and no longer reduce, except the operation of non-recovery selecting arrangement.
When pin 6 is in the top cylinder 42 and with sliding part 3 ' when cooperating, similar described operation also can occur.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 at the yarn feeding A place that considers knitwear and syringe, the pin 6 in the bottom cylinder 1 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, owing to heel 4a reduced with cooperating of retraction 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 considers, 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 considers 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 facing up syringe 42 the side and be similar to selecting arrangement or the pressing device that arranges at selected element 21 places.
Therefore, after sliding part 3 ' being drawn out of cam 28 ' cooperation promotes, owing to heel 4a reduced with cooperating of retraction 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 (these rotation directions with usually opposite directions) 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, owing to heel 4a reduced with cooperating of retraction cam 33 at its heel 3a.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 considers, and forms new knitwear ring, reduces the previous knitwear ring that forms.
The yarn feeding A place that is considering, in the process of passing through the yarn feeding A place that considers, 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 the 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 the 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, namely 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 yarn feeding place of being considered, usually knitting by realizing with the device that is called hammer or pick-up and flap in the knitting machine of traditional type, thus the present invention need not to adopt these devices.
In the time pin 6 must being transferred to another syringe from a syringe, by be arranged on selected element 25 and facing up the selecting arrangement at the corresponding selected element place of syringe 42 begin transfer operation, 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 ' close to each other, thereby cause that the hook-shaped lug 7 on corresponding heads 6a, the 6a ' of its longitudinal end and pin 6 is overlapping.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 at pin 6, the slip on the 6a ', stand in the sagittal plane to swing, 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 ' 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 ' simultaneously cooperation.
This moment, by the 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 mobile described pin 6 is knitting to carry out 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 that the direction of all sliding parts 3 of being arranged in the top cylinder 42 ' move apart along its hook-shaped lug 7 bottom of corresponding axial groove 2 swings.
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 ' swing along the direction 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 impact 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 arranged on sliding part 3 in the bottom cylinder 1, that also do not cooperate with its heel and bottom reduction stationary cam 56 and cooperates.
Also do not cooperate the bottom to reduce the sliding part 3 of stationary cam 56 so run into the bottom and open pressing device 58, cause that it swings along the direction that makes hook-shaped lug 7 move apart 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 swinging with cooperating again in opposite direction 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 the first embodiment with for referring to the knitting machine among the 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 the purpose of expection, because its allow to reduce even exempt the movable cam in the cam set that arranges around syringe, but can basically realize all knitting kinds that the circular knitting machine that is used for hosiery or analog of traditional type can be implemented at present.
