SU93399A1 - Method and device for fancy work at round-filling automatic machines of products with closed toe, starting from toe - Google Patents

Description

The invention relates to methods for folding on round-plate machines of products with a closed toe, eliminating the need for subsequent ketch toe products, and to organizers for carrying out this method.

Compared with the known method, for the production of closed toe products on knitting machines on round knuckle machines, in which hooks, which were mounted movably in a head, swivel, were used to transfer the initial thread loops on short needles. 180 ° down around the horizontal axis, in the proposed method, the whole process of its implementation is simplified, pulling the loops of the initial thread from the needles with short hems and transferring these loops to the needles with long hems is done by initial upward rotation of the head with petleperenosnymi krvchkami.

This simplifies the design of the device for carrying out the proposed method, since a device with a swivel-down head carrying loop-mounted hooks cannot be installed directly on the needle cylinder, which complicates the process of taking a closed loop, requires the use of a more sophisticated drive alterations of the round bowel machines.

The proposed device is simpler, since in it, for synchronous rotation of the head, together with the needle cylinder of the circular blender, the head is rotatably mounted on the horizontal axes of the ring fixed by ITS lug on the crown of the cylinder.

FIG. depicts the reciprocal location of the petdeforming organs of the round-bout automaton in the formation of the initial loops of the toe; FIG. 2 shows the arrangement of the same organs when dropping the initial loops of the myok on the needles with long naps; FIG. 3 is a longitudinal section of the device head; on Fig.4, the fragmentary section of the needle tsilidra machine with the device in position in the underload of the initial loops of shock; figure 5 is a view of the device head from above; Fig. 6 is a longitudinal section of the needle cylinder with a device for turning its HEAD}; Fig. 7 is a longitudinal section of the needle cylinder and the device head and dropping loops from the hooks of the head to form a closed toe; on figb - view of the device head from above along arrow A on fngr7; figure 9 is a partial section of the needle cylinder and the device head in its on position, i.e. with a circular viscous product.

The proposed method consists in that the head NIY-i (see fig.) Progresses at the swinging dviendi of cylinder 2 on its needles 3 with short hems, located on one half of it, and on the loop-transfer forked spring hooks 4, gradually inserted between the needles. The loop-mounted movably mounted in the radial slots of the head 5, by rotating it 180 ° around the horizontal axis 6 upwards in the direction of the arrow B (see Fig.6), the initial loops of the toe 7 are pulled back during transfer to the initial loops 7 them on opposite needles 8 with long ni.

A device for carrying out the inventive method. Includes a head with loop-mounted hooks, mechanisms for turning it 180 °, and for closing the head lock washer when pulling the loop-mounted head.

The head 5 is made synchronously rotating with the needle cylinder, for which a ring 10 is mounted on its crown by means of a protrusion 9, and is connected with two bearings M for the axes 6 of the head. The head contains a semi-washer 12 with radial slots for loop-mounted hooks 4 and 3aM04HyjD sha & 13, with a pin 14 of loop-proof hooks.

To provide a more reliable hold-off of the initial locks of the myok, which are pulled off and carried by the loop-carrying bowls, there are fixed valves 15 between the hooks, held by the arc 16 (FIG. 3) attached to the half-heel 12. The valves are snocked by the tips 4 facing the side of the moving-hooks 4 and the images of them closed ears for loops with hooks pushed inside lolushayba.

Sleep washer 13 (3ken protrusions 17, with the initial loops of the toe 7 facing upwards and the supporting stops 1§ on the platform 19 in the vertical direction (Fig.9) for scissors, and when dropping the loops after turning the head 180 ° downwards - and held by the lugs 20 (Fig.7 and 9) located inside the cylinder and movable in the vertical direction of the outlet pipe 21.

The mechanism for moving the withdrawal pipe is made in the form of a hinge 22 connected to it by a link 23 (Fig. 7), which interacts with the hinge 24 of the crank 25 of the drive shaft 26.

In order to engage the ztyur 20 of the outflow pipe with downward protrusions 17 of the lock washer when the loops are looped from the looped hooks to the needles 8 with long stitches, the link is connected by a hinge 27 to the pusher 28, which interacts with its spring head 29 with the power cam 30, the mechanism for reversing The tail consists of a hinge 31, 32 and 32, connected to it, which is provided with a spring link 33 in the middle part, designed to equalize the tension during pulling of the manufactured toe. T ha by means of a hinge 34 is attached to a ring c5, the upper of two rings calzdoe of which is arranged to move along the cylinder qilin from the lever 37 entering the ring groove of the finger of the finger rotating on the axis 38 (see figure 4). On the other arms of both levers 37, bags 39 are installed with rollers entering the grooves 40 of the cam of the driving drum.

The lower ring 41 cooperates with the spring end 42 of the ty for the passage of this pull of its dead position with the middle position of the rotatable head.

The proposed device works in a similar way.

By lowering the platform 19 for the scissors, the ynopj 18 interlocks with the projections 17 of the lock washer, thereby delaying its rotation, thanks to the skull, when the cylinder rotates with the head 5 mounted on it, the looped hooks 4 are gradually extended into the interstices between the needles 3. At the same time, thread 1 is laid. on these needles and loopholes put forward, on which the thread is sticking. When retracted into the inside, the loop-like hooks form closed ducks with the nozzles of the fixed valves 15, firmly holding platinum arches of the first row of toe loops.

During the next swing of the cylinder, the platform is raised to release its lugs 18 with the projections 17 of the lock washer, thereby releasing the lock washer and the looped hooks remain in the 12 position retracted into the floor.

At the same time, the head is turned around the horizontal axis 6 by lowering the hinge 32 pivotally connected to it, which results in a detuning

removable toe 7 and the transfer of its initial loops to the opposite needles 8 with long pk.sh.

After turning the head through 180 °, the outflow pipe 21 is raised, thereby achieving the coupling of its stops 20 with the lugs 17 of the lock washers facing downwards. When the lock washer is locked one swing of the cylinder, a gradual extension of the loop-attached hooks occurs. The expanded portion of the looped-on hooks is installed above the heads of the lowered needles 8 with arc nuggets. When these needles are lifted, they pick up the platinum arcs of the hinges of the first row of the toe, after which the loop-transfer hooks from the action of the first lock of the lock washer move away from the needles to the center of the head, and the stops 20 of the outlet pipe disengage from the projections 17 of the lock washer, thus turning off device action.

With further circular rotation of the cylinder, circular formation of the tubular part of the product is performed in the usual way,
