Method and machine for knitting tricot-wear with the aid of tongued needle

专利摘要:
To insure gentle latch operation, and particularly gentle opening of the latch, the last-knitted loop (36) is constrained to move in the same direction as the needles (2) by controlling movement of sinkers (7) in the same direction as the needles, at a speed slower than needle speed during the raising phase of the needles (FIGS. 5, 6), so that initial movement of the latch occurs slowly and not abruptly to permit faster knitting speeds by reducing stresses on the latch. Conversely, during closing movement of the latch (FIGS. 9, 10), initially, the loop and the needle are lowered simultaneously, the lowering speed of the loop, controlled by the sinker (7) being slower than the lowering speed of the needle. Cast-off can be improved by rapidly controlling the loop by suitable sinker movement (FIGS. 11, 12). The projection distance of the needle can be decreased to at most that of the latch motion distance by constraining the loop, held on a sinker as well as on the shaft of the needle, to a position below the rest position of the sinkers by suitable construction of the sinker cam (15, 15a, 15b; FIG. 2).

The invention relates to the technology of knitted production, namely, the method of knitting knitwear on machines with tongue needles.
The purpose of the invention is to increase the ca-. the quality of the product.
FIG. 1 shows a knitting machine, a slit; in fig. 2 and 3 - to profiles of channels of the needle and platinum locks, options; 4-12 show the relative positions of the needle and its corresponding platinum at various stages of the loop formation process. js
The needle cylinder 1 of the rounding machine, other known parts of which are not shown in the drawing, is provided with clamping needles 2 on its circumference, which are mounted parallel to each other and have the ability to move in the longitudinal direction. Reed needles 2 have on their rods x 3 pt 4, which enter the canal of the needle lock 5 of the locking ring 6 located near the needle cylinder 1, which is made in a known manner from several parts (not shown). By means of a drive means (not shown), the needle cylinder 1 is rotated (arrow 0) relative to the lock ring 6. Due to this relative movement, the channel of the needle-shaped lock 5 informs the needles 35 of the needles needed to carry out the process. movements for raising and lowering needles.
Between two tongue needles 2
Platinum 7 fender installed, which is good for needles during radial motion
The rat protrudes above the edge of the needle cylinder 8 and has a neck 10, a nose 9 and a curly edge 11. Each baffle plate 7 is provided with a rod 12, with which it is mounted on the needle cylinder 1, located directly between the rods of adjacent needles 2. For this the needle cylinder 1 is inserted a radial guide plate (not shown), which is mounted at a distance of the needle rod and forms a direct radial bearing and work surface for the needles 2, and
also lateral guides for glide lines form an angle with the horizontal
directly along the edge 24 of the needle movement.
needle cylinder rods platinum. Directly from the needle needle, each platinum rod has a small wedge 22 profile 21 needle holes.
pc 13, which enters the channel 14 of the castle is formed by a part in the form
a platinum lock, made on the lock box 5, and is controlled with it so that the fender plates 7 are motioned to extend and lower them.
The fla needle cylinder 1 is provided with a platinum pushing locking 15 near the edge, which in form is an inclined surface extending outwardly to the edge of the needle cylinder 8, made directly by a bore on the cylinder, on which the baffle plate 7 supported on the rod 12 is supported. Platinum-ejecting lock 15 operates as shown in FIG. 4 to 10; in this case, when the rods of the platinum are advanced by means of the channel of the platinum lock, the baffle plates 7 are moved radially outward. In order to ensure long engagement of the nozzles 16 with the lock 15, the rods 12 of the platforms in the zone of the pushing lock 15 are under the action of a spring force directed radially inward towards the base of the cylinder and produced by two infinite tension springs 17 tensioned around the cylinder, which simultaneously rest on the side protrusions 18, made on the rods 12. The rods 12 of the plates protrude in the radial direction by a certain amount over with the needles of 3 needles, as a result of which the springs of the 3 needles do not act on the springs 17 and do not move them.
In order to prevent the needles 3 of the needles from being caught by the baffling plates in the hopplatin zone, they are pressed in the area between the push-in lock 15 and the edge of the needle cylinder 8 radially inward with the spring 19 passing around the cylinder. The bars 12 of the plates have an open groove 20, which ensures that that the spring 19 does not move the baffle plates 7.
The needle lock profile 21 (FIGS. 2 and 3) has at least one pushing part, designated as a needle wedge 22, the corresponding part 23 of which extends approximately along a straight line.
needle wedge 25, the straight part 26 of which forms with the horizontal an angle 27 of descent. When moving along the profile 21 of the needle lock, the latch needles 2 at point 28 occupy their main position or drop position, and at point 29 they are in the confinement position (Fig. 4, 8).
The profile 30 or 3 of the platinum lock has an extension part in the form of a platinum lifting wedge 32, the straight part 33 of which forms an angle 34 of advancing the platinum, which is smaller than the angle 24 of the extension of the needles. The platinum lifting wedge 32, located in the area of the needle lifting wedge 22, is designed so that from the point 35 of the profile of the platinum lock, the fender plates 7 are driven to move which advances the platinum and simultaneously coincides with the advancement of the needles, while the advancement speed of the platinum 7 is lower compared to the speed extension of the needles 2. The path of extension of the needles, starting from the main position (point 28) before the start of the extension of the baffle plates, indicated by point 35, corresponds approximately to the length of the space where the thread in the tongue needle 2.
The length of the platinum lifting wedge 32 in the direction of the circumference of the lock box is less than the length of the corresponding needle lifting wedge 22. It is designed so that after passing through the section 33 of the platinum lock, the baffle plates 7, located at point 36, take a position in which the needle tab 37 ( Fig. 7) is completely open and previously formed in the loop 38 which precedes it in the gate system, is still located on the needle open tab 37 which is open with a help of it.
A platinum lowering part in the form of a platinum lowering wedge 39 adjoins the platinum lifting wedge 32, part of the profile of which with a horizontal form an angle of 41 lowering of the platinum. The platinum lowering wedge 39 is mounted so that the lowering motion of the baffle plates 7 is basically completed when the tongue needles 2 reach their imprisonment position at the point 29 of the curve (Fig. 8). Profiles 30 and 31 are made in such a way that the fender platinum 7 when the tongue needles are located in full

the closed position, in the confinement position, is so drawn back that the loops 38 located on HI "are held at a distance X from the tip, the needle's open tab 37 (Fig. 8). The point corresponding to this position on the expanded profile 30 of the platinum lock is marked 42, on the profile 31 of the platinum lock - figures 43. Profiles 30 and 31 of the platinum locks at points 42 and 43 are located below the horizontal corresponding to the main position at point 35. This means that the fender plates 7, when the tongue needles are fully extended, are retracted 2 below the main position. Due to this, the necessary needle path is shortened accordingly as they move.
Profiles 30 and 31 of platinum have, at the first platinum lowering wedge 39, a second lifting platinum wedge 44, angle
45 of which is chosen in such a way that the breaking of the platinum 7 during the movement of the needles 2 with the aid of the retracting wedge is again advanced before the old loop hanging on the stem 3 of the needle does not come into contact with the fully open tongue 37 of the corresponding needle (Fig. 9) Next to the second platinum wedge 44, the second lowering platinum wedge
46 has a lowering angle 47, which is less than the lowering angle 27 of the needle wedge 25. The second lowering platinum wedge 46, located in the area of the needle lowering wedge 25, is designed in such a way that its surface passes through the area of the lowering needle wedge corresponding to the part of the lower needle path 2, done before closing the corresponding tabs 37 needles. Due to this baffling platinum, when closing the needles of the 37 needles, a platinum-lowering movement is said to have the same direction as the needles of the needles, the speed of which is less than the speed of the needles, which causes the tabs 37 to close more gently, thereby reducing the load on the tabs 37 and on the needles themselves 2.
In cases where the soft closing of the tabs of the 37 needles is not required, the second lifting platinum wedge 44 and the second lowering platinum cutting 46 may be missing.
The profiles 30 and 31 of the platinum locks (Figs. 1 and 3) are different from each other in that the profile 30 of the platinum lock has a cooler 48, i.e. the baffle plates 7, while the lowering needle of the mandrel 25 is in working condition, remain in a partially extended position. In another profile 31 of the platinum wedge, the next lowering platinum wedge 49 in the form of the lowering platinum wedge 46 is attached. It is also located in the zone of the lowering needle of the wedge 25 and acts so that the baffle plates 7 during the movement, lowering and quenching of the needles 2 are advanced in the direction opposite to the movement of the needles. In this case, the angle 50 to the lifting platinum wedge 49 can be chosen such that an improvement in the cooking process takes place with a lower loading of the filament.
The next platinum lowering wedge 51 is adjoined to the next lifting platinum wedge 49 or the cheating part 4, which returns the discharged platinum back to its original state.
The proposed round ealna works as follows.
In the main position (Fig. 4), the corresponding tongue needle 2, respectively, to point 28 of the profile of the needle lock 5 is completely omitted. The tongue 37 of the needle is closed. In the hook 51 of the needle 2, the last loop 38 hangs. It is held by the holding nose of the corresponding platinum 7, which is also in the main position.
Starting from the main position, the zychkovy needle 2 in the following period of time extends in the direction indicated by the arrow 52, while the baffle plate 7 remains first in the loop-holding position, in which it was previously transferred in the direction of the arrow 53.
Next, the zychkov needle opens and makes a path that approximately corresponds to the length of the space in the needle head where the thread is placed (Fig. 5). The hook in the needle head of the loop 38 is directly in the position when it is

will come into contact with the closed tongue of the 37 needle.
The breakaway platinum 7 starts its extension at point 35 of profile 30 or 31 of the platinum lock, which coincides with the direction of movement of the tongue needle 2, which is indicated by arrow 54. The tongue needle 2 continues its extension according to arrow 52.
The tongue needle 2 and platinum 7 continue their extension (Fig. 6) according to arrows 54 and 52, while platinum 7 according to profile 30 or 31 of the platinum lock reaches the middle of profile 33 of the lock of the platinum lifting wedge 32. Because of the larger (steeper) ) angle 24 of needle extension compared to angle 34. extending the pullout of the tongue needle is carried out at a higher speed compared to the speed of movement of platinum 7, the bowl 37 of the tongue 37 is previously closed relatively slowly on the loop 38 hanging in the needle hook, due to which the needle of the needle opens more slowly.
In the process of further expansion of the needle in direction 52 (Fig. 7), a position is reached in which the baffle plate leaves the wedge 32 to lift the plates and goes to the wedge 39 to lower the plates, at which point it changes its direction of movement and begins to lower and move in the direction opposite to the needle, which is indicated by the arrow 55. At the point of change in the direction of movement of the platinum, the loop 38 that hung earlier in the needle head is adjacent to the fully open tongue 37 of the needle. The baffle plate is in the position of locking the loop, so that the loop 38 is held securely.
The tongue needle (fig. 8) reaches the conclusion position corresponding to point 29 of the profile 21 of the needle lock, while the baffle plate 7 (which still holds the loop) drops below the main position or the position of the circular movement, which corresponds to point 42 or 43 of profile 30 or 31 platinum lock. By holding the baffle plate 7, the hinge 38 is pulled to a lower position, which ensures a reliable distance X from the tip of the open needle tongue. The path of extension of the tongue needle is smaller.

or the maximum is equal to the length of the needle hinge 56, since the loop 38 is forced down to the lower position by means of the baffle plate 7.
The tongue needle 2 is then lowered with the help of the lowering wedge 25 in direction 57, while the baffle plate 7 is turned in the opposite direction with the help of the second lifting wedge 44 in comparison with the movement of the syringe needle 2, as indicated by the arrow 54 (FIG. B) Extend the baffle plate 7 ends before it reaches a position in which the needle 38, which lies on its cutting edge 11 and hangs simultaneously on the needle shaft 3, comes into contact with the fully open tab 37 of the needle 2. The loop 38 finds - 20 seconds in position which it touches the needle tongue 37 slightly, which can be called the beginning of the closing tongue of the tongue (Fig. 9).
The breaking of the platinum during the collision of no-25 sikom 16 on the advancing platinum charge. The bag 15 moves radially outward relative to the needle head 1 to the position in which its retaining nose releases the loop 38, as indicated by the arrow 58 (Fig. 8).
The breakaway platinum 7 now falls into the zone of the second platinum lifting wedge 46, which informs it of the movement, cpv.

Now the zychkovy needle 2 moves to the stopping position while the otping plate 7 of dreams changes the direction of movement and with the help of the next lowering wedge 51 moves in the same direction with the needle to its main position (Fig. 12, arrows 55, 57). When lowering the baffle plate, it makes a movement (arrow 53), directed radially inward of the needle cylinder, as the nose 16 moves away from the push-in lock 15. Thus, the baffle plate occupies the loop retention position (Fig. 12), while the zychkov needle finally reaches its main position
This again achieves the position shown in FIG. 4, from which, in the following EY system, a new loop is obtained by the described method.
According to the platinum profile profile 30 (Fig. 2), the baffle plates are poured in after being lowered, caused by the second lowering wedge 46 and carried out in the same direction as the tongue needles, in part
zychkova needle 2, shown by the arrow - 5 extended position, which is defined
Which 55 (fig. 9).
Since the lowering angle 47 of the second lowering plate of the wedge 46 is less than the lowering angle 27 of the needle lowering wedge 25, the lowering of the baffle plates 7 occurs at a slower speed compared to the lowering speed of the needle needles 2, thereby closing the needle 37 of the needle to close gently ( Fig. 10 shows the moment when the needle's tab 37 has done half the way of the zakrshan). Thread 59 is laid under the needle hook.
FIG. Figure 11 shows the continued downward movement of the tongue needle 2 at the end of the closing phase of the tongue. The tongue 37 of the needle is completely closed and the new loop of the thread 59 is under the hook of the needle.

Now the zychkovy needle 2 moves to the stopping position, while the baffle plate 7 again changes the direction of movement and with the help of the next lowering wedge 51 moves in the same direction with the needle to its main position (Fig. 12, arrows 55, 57). When lowering the baffle plate, it moves (arrow 53), directed radially inward of the needle cylinder, as the nose 16 comes off the push-in lock 15. Thus, the baffle plate occupies the loop retention position (Fig. 12), while the needle finally reaches its main position.
This again achieves the position shown in FIG. 4, from which, in the following EY system, a new loop is obtained by the described method.
According to the profile 30 of the platinum overhang (Fig. 2), the fender platinum is stopped after its descent, caused by the second descending wedge 46 and carried out in the same direction as the tongue needles, during the cooling process in part
