Description

The subject of the invention is a device for charging cassettes on an automatic rewinding machine using inclined feeding trays.

The proposed device, in comparison with the known similar devices, mechanizes the process of charging the cassettes with spools, providing them with an alternate supply, and increases labor productivity.

In the device, an intermittent swinging movement of a rocker with a socket for a pin on one end is applied; the other end of the rocker arm is connected to the main shaft of the machine gun by means of a crank mechanism and a cam clutch; The cam clutch is controlled from the machine of the machine with articulated links.

In order to distribute the chips, the cassette racks used a rotary valve on the axis, mounted on the bottom of the feeding tray and carrying out an osh, and swinging movements from the drive through ratchet and shatunno-Krivostipny mechanisms.

For clamping the thread thread at the shears of the automaton before it was cut, two plates were used, one of which was fixed and the other

The end is pivotally fixed on the axis and is connected to the end of the rod, which interacts with the help of the rod with an automaton.

FIG. 1 shows the layout of the device on the automatic winding machine; in fig. 2 - scheme of the operation of the spool of the machine; in fig. 3 is an interconnection diagram of the rocker arm with the main shaft of the machine gun; in fig. 4 - diagram of the mechanism of the drive distribution valve; in fig. 5 is a diagram of a spool distribution mechanism; pas figs. 6 is a diagram of the mechanism for clamping the end of the thread of the scissors; na fmg. 7 is a schematic diagram of the technological process of cassette charging with spools.

From the bottom of the bobbin box of the automaton, a push-pull-and-pull mechangism / switching-on device with a cam clutch is installed, driven from the main shaft 2 of the automaton (Fig. 1).

The mechanism 3 of the weft thread is located on the shear of the scissors 4 of the machine gun and is driven from the spool of the machine gun.

The supply of bobbins with yarn to the cassette 5 is carried out along inclined feeding trays 6 and 7, in which the bobbins move freely under the action of their weight.

For, alternately and filing PTUL n

The ycipOMCIJai cassette is equipped with a corse-thought 8, performing intermittent swinging movements on axis 9.

A cassette of known construction, having overlapping clans to eliminate the possibility of a spzl falling out of it, is mounted downwards in the valve guides.

The mechanism / kinematically connected with a pshul rnik 10 of the automaton and turned on the shnul rnik (Fig. 2).

When changing the accumulated Н1пулн // sewed the rink turns on the axis 12, and the roller 13 fixed on it, is not rendered from the position L to position B.

The roller 13 Iri reamer finds on the hill 14, which descends together with the double-cheche link 15 connected to it, the other arm of which through link 16 turns the double shoulder link 17 (Fig. 3). When turning the case counter-clockwise, the pin 18 connected with it, but at the same time, comes out of its body with the bevel of the finger 19.

Palen 19, under the action of a spring, does not shake, left to the left (but to the drawing), and engages with the front level 20, fixed on the wormhole 21.

The worm gear 21, freely rotating on the flank 22, is coupled with the worm 23, sitting on the same shaft with an asterisk 24, lying with a chain transmission from the main shaft 2 of the machine (an asterisk, a worm, a worm gear and a ratchet constant vrandenne).

From shaft 22 through gyesterni 25 and 26 and m, g 27, a rocker arm 8 is rocked, having a nest at the end for the socket.

When the rocker arm rotates clockwise, its end with the socket and the pshule sitting in it is included in the cassette 5; The reverse movement of the yoke is pushed back into the three cassettes by a valve located on the inside of the cassette.

The spools are distributed across the cassette rows by a mechanism that is activated by the movement of the rod 28, which causes the movement to turn freely on

axis 29 bar 30 (Fig. 4). On axis 29, the ratchet wheel 31 and gear 32 rotate freely.

On the rail 30, the pin 33, which is pressed by the end to the ratchet wheel 31, is moved by the spring 34 in the guides.

The reversing of the ratchet wheel 31 and gear 32 is limited by the pawl 35, which unifies by the end of the gear teeth.

Gear 32 is attached to the top 32 and attached to the spindle, carrying a CRIMO 37, connected to 38 (Fig. 5). The end of the bottom 38 is located in the lever of the lever 39 between the springs 40.

The lever 39 is fixed on the same axis 41 together with the distribution flap 42 mounted on the bottom of the nutritional tray 7.

Lever 39 shifts from position B to position G, and flap 42 from position D to position E.

The clamping of the end of the weft yarn is carried out by two metal plates 43 and 44 (Fig. 6). The plate 43 is hinged on the axis 45, and the plastic 44 is not well installed. The Chinese plastic 43 is connected to the end of the rod 46, which interacts with the stitched edge of the 10 machine gun.

When changing the accumulated noshuli, the bobbin 10 turns counterclockwise and moves the pins 46 in the guides with the help of the pull 47. The replenishment of the npig; n- (occurs at the moment when the end of the rod has not reached the stubby shoulder Plastie 43.

When moving to the trays of the spool with the shears wound on it, winding of the nitn from it occurs in the axial direction, since the end is pre-fixed in the clamps of the scissors of the machine.

The coiled thread from the shank to the clamp is in the lowest state and is located between the blades of the scissors and between the nastinamn 43 and 44.

With further movement, the shavings of the rnik and the stem 46, the end of the near-early one abuts against the plate area 43 and rotates it. Plast H1a 43

by means of a spring 48, it is pressed against the plate 44. After the thread is clamped, the shears come into play and cut the thread.

The konpa of the thread is clamped against rotation of the bobbin, and the release of the end is performed by a mechanism for gripping and withdrawing the end of the thread.

The plate 43 is pivotally connected by a pull 49 with a lever 50 rigidly connected with a column 51 on which the lever 52 is fixed.

The grip and retraction end 53 lever rotates clockwise (shown by dotted lines).

The grip is located below the zazh.imov threads. The thread is caught by the gripping jaws and is brought to the lever 52. With a further movement of the gripper, the ends of the jaws meet the lever 52 and turn it, moving from the position F to the position K. Simultaneously, one hundred to five turns and, through the lever 50 and four, 49 retracts the plate 43, releasing end of the thread, driven away by the grip.

The technological process of charging the cassettes on the rewinder is carried out as follows (Fig. 7).

First, the thread 54 is wound onto the spool, after which the chip falls into the tray 6, from which, under the action of its weight, the switch:.

Moving along tray 7, the ntul enters the rocker arm nest, holding the position /.

After securing the piti in the clamping mechanism 3, the opa is cut by yuzhnytsami 4.

The end of the thread from the shpuli rounds the edge of the tray 6 and is held in the mechanism 3 of the clip.

In positeness, the spool in the cassette does not change its position in comparison with the position /, and the end of the thread exerts a protrusion 55 of the locking mechanism and is clamped with clamps 56 and 57.

In ps. Zhenzhenin / / / khents yarns, clamped by the valve, do not change their curing in comparison with the full: P, and the cassette is filled with stitches.

In polsseniy IV, a cassette filled with chips was depicted. Konshchz threads removed from the cassette n led under the plate 56 and 59, located on the front wall of the cassette.
