Description
Technical field
The present invention relates to adopt latch needles as knitting needle, the straight-bar machines that can also between the needle-bar of making knit fabric, carry out barring-on and loop transfer method thereof, its cam mechanism.
Background technology
In the past, in straight-bar machines, the tooth mouth place between needle-bar in opposite directions made knitting needle advance and retreat from each needle-bar and formed coil, and the barring-on operation that coil is moved, thereby knit out knitted fabric.The pinhock seizure that the knitting needle utilization is formed at the shank front end is fed into the stocking yarn of tooth mouth and it is drawn in needle-bar, forms coil.When making knitting needle enter the tooth mouth under the state that the coil card is ended in pinhock, institute block coil only and moves to the mid portion of shank from the pinhock disengaging of the front end of shank.Forming in the lopping of action as basic coil, at the tooth mouth stocking yarn is captured on the pinhock, draw in needle-bar and form new coil, at this moment, the coil that moves to the mid portion of shank breaks away from from the pinhock knocking over, becomes the old coil that links to each other with new coil.In latch needles, possesses the needle latch of when forming old coil, closing pinhock by knocking over as representational knitting needle.
Fig. 1 (a) is that the benchmark part illustrates the method for the side in the needle-bar in opposite directions being carried out barring-on as the transfer side to transfer side knitting needle 1.Transfer side knitting needle 1 and have the pinhock 2 that top side bends to hook-shaped and opening, open and close pinhock 2 by needle latch 3 at front end.Be formed with the mid portion of the shank 4 of pinhock 2 at front end, formed the step difference that is called as shoulder 4a, be provided with blade 5 in a side of shank 4.Blade 5 is closed between the side with front end 5a and shank 4, mid portion and the side of shank 4 between have the gap.On shoulder 4a, hang with the upper end 6a of barring-on coil 6.The lower end 6b of barring-on coil 6 is hung on the bottom surface side of shank 4, is connected with the upper end 7a of old coil 7.Pass through the outside of blade 5 and the another side of shank 4 between the upper end 6a of barring-on coil 6 and the lower end 6b.
Transfer the tooth mouth 8 that side knitting needle 1 enters between needle-bar by making, barring-on coil 6 moves to the position of shoulder 4a in the pinhock 2.In addition, in straight-bar machines,, transfer side knitting needle 1, the vertical below 8a of the tooth mouth 8 in the straight-bar machines is represented obliquely along the ground expression of level advance and retreat although be inclined to when when tooth mouth 8 leaves, descending across tooth mouth 8 needle-bar in opposite directions.
According to along the approaching relatively mode in linearity path 9, make receiver side knitting needle 11 enter tooth mouth 8, in the gap of the blade 5 that pinhock 12 is entered into hang with barring-on coil 6, carry out barring-on.The pinhock 12 of receiver side knitting needle 11 is closed by needle latch 13 usually.When receiver side knitting needle 11 enters in the gap of blade 5, need utilize the upper end 6a of barring-on coil 6 to open needle latch 13.Thereby,, when entering tooth mouth 8, transfers on upper end 6a that side knitting needle 1 stops at barring-on coil 6 crook and the position between the front end of needle latch 13 by pinhock 12 on track 9 at receiver side knitting needle 11.Represent that with solid line the pinhock 12 of receiver side knitting needle 11 begins to enter the state in the barring-on coil 6, the upper end 6a that is represented by dotted lines barring-on coil 6 enters and state between the front end of the crook of pinhock 12 and needle latch 13 and enter midway state.
The summary that Fig. 2 (a) shows the selecting transfer cam 20 of the transfer side knitting needle 1 that drives Fig. 1 (a) constitutes (for example with reference to patent documentation 1).Selecting transfer cam 20 is carried on the cam carrier that is provided with the needle-bar walking of transferring side knitting needle 1 along arrangement, comprises conversion guiding triangle 21 and transfer receiving dual-purpose selecting transfer cam 22.Between conversion guiding triangle 21 and the dual-purpose selecting transfer cam 22 of transfer reception, form and transfer side directed groove 23.Because cam carrier is back and forth walked with respect to needle-bar, so selecting transfer cam 20 has the shape that is the line symmetry about center line 20a.
Imagination selecting transfer cam 20 is with respect to the occasion of the knitting needle of being located at needle-bar to the left walking.Transfer side knitting needle 1 in the action part of the barring-on shown in Fig. 1 (a) is called in person with the pin that will drive usefulness from position 23a in transferring side directed groove 23 and is guided to the interval corresponding of position 23b.In this interval,, be that approximate horizontal shifts substantially though transfer the in-position that side knitting needle 1 can change slightly with respect to tooth mouth 8.Therefore, be to make that to transfer side knitting needle 1 static shown in Fig. 1 (a), make receiver side knitting needle 11 approaching relatively.Transfer the downside that receives dual-purpose selecting transfer cam 22 and work, to the enter channeling conduct of receiver side knitting needle 11 to tooth mouth 8 as receiver side guide portion 24.The interval from position 23a to position 23b of transferring side directed groove 23 is corresponding with the sloping portion that is equipped in the knitting needle rising usefulness of the receiver side guide portion 24 of the selecting transfer cam 20 of the cam carrier of walking across tooth mouth 8 needle-bar in opposite directions, and receiver side knitting needle 11 continues to enter at tooth mouth 8.
Transfer side knitting needle 1 in transferring side directed groove 23 by being located at the peak shape part of both sides across center line 20a, so, in the path of the bimodal shape at peak-paddy-peak, carry out lifting and with respect to tooth mouth 8 advance and retreat.Side's side of the center line 20a of receiver side knitting needle 11 in receiver side guide portion 24, only guided in the interval corresponding with becoming the peak portion of transferring side directed groove 23 rear sides.Therefore, the peak portion of transfer side knitting needle 1 in the front side do not carry out barring-on and advances and retreat with respect to tooth mouth 8.By these advance and retreat barring-on coil 6 that can relax.
[patent documentation 1] (Japan) special fair 2-10262 communique
In existing barring-on process, when the transfer side knitting needle 1 of Fig. 1 (a) rises and when coming the par of summit, the pinhock 12 of receiver side knitting needle 11 enters in the blade 5 in the second peak portion of the side directed groove 23 of transfer of Fig. 2 (a).When this enters, be positioned at the upper end 7a of old coil 7 of the bottom surface side of transferring side knitting needle 1 and the upper end 6a of the barring-on coil 6 that ends by the 4a of the shoulder portion card of transferring side knitting needle 1 and contact with the pinhock 12 of receiver side knitting needle 11.After the contact, transfer side knitting needle 1 and do not rise, receiver side knitting needle 11 further rises along linearity path 9, and the leading section of the needle latch 13 of closing contacts with the upper end 6a of the barring-on coil 6 that is ended by the 4a of the shoulder portion card of transferring side knitting needle 1.When receiver side knitting needle 11 advances one one when rising, needle latch 13 is opened, and the upper end 6a of barring-on coil 6 is captured in the pinhock 12.Then, transfer side knitting needle 1 and receiver side knitting needle 11 descend and retreat from the tooth mouth, finish barring-on.
In the action of barring-on, importantly, the upper end 6a of barring-on coil 6 is put into receiver side knitting needle 11 pinhock 12 the top and close between the front end of needle latch 13 of pinhock 12, and before this moment, at the front end of pinhock 12 with when the upper end 6a of barring-on coil 6 contacts, upper end 6a is not the bottom side that forwards pinhock 12 to, but forwards needle latch 13 sides at top to.Also have at the front end of pinhock 12 with before the upper end 6a of barring-on coil 6 contacts, be positioned at the first situation about contacting of a side of upper end 7a of the old coil 7 of the bottom surface side of transferring side knitting needle 1 with the bottom of pinhock 12.Under this contact action, pinhock 12 is lifted by old coil 7 pushings, and at this moment, the upper end 6a position contacting of the front end of pinhock 12 and barring-on coil 6 becomes bottom side, exists upper end 6a to forward the worry of the bottom side of pinhock 12 to.
The contact need of the leading section of the needle latch 13 of closing and the upper end 6a of barring-on coil 6 utilizes barring-on coil 6 to open needle latch 13 to carry out.The position of receiver side knitting needle 11 and barring-on coil 6 concerns when undesirable, and the front end of needle latch 13 can bur be gone into the upper end 6a of barring-on coil 6, and perhaps barring-on coil 6 forwards the bottom side of pinhock 12 to, causes barring-on bad.Such barring-on is bad may to occur in that the intensive grade of coil reduces the loop density value and during the barring-on of the coil that forms.For the barring-on coil 6 that forms by common loop density value, be to expand out barring-on coil 6 on the contrary by the old coil 7 of receiver side knitting needle 11 pushings, can enter in the barring-on coil 6, so no problem at the barring-on aspect of performance.
When from the intensive coil of coil when barring-on coil 6 shifts because girth is shorter, the disappearance more than needed that the card that forms the shoulder portion 4a place of transferring side knitting needle 1 relaxes when ending and to be subjected to restrain (Poor in the wrong) state.Therefore, when the pinhock 12 of receiver side knitting needle 11 contacted with the upper end 7a of old coil 7, receiver side knitting needle 11 was lifted by old coil 7 pushings, and entering in barring-on coil 6 also becomes contained.Thereby, the problem etc. that broken yarn or barring-on coil 6 forward the bottom side of pinhock 12 to can take place.
