SU41621A1 - Device for automatic shutdown of the system of the round knitting machine of the English type - Google Patents

Description

The present invention relates to a device that shuts off a round knitting machine of the English type from the operation on a clipping, pulling or gathering of one of the two threads feeding the system. For this purpose, the second one is cut from the threads and the press is moved away from the needles, in order to prevent knitting.

In FIG. 1 is a side elevational view; FIG. 2 - its front view; FIG. 3 is a top view; FIG. 4-view (partly in section) of the press cartridge.

To the side of the cartridge 2, which belongs to the machine, is reinforced. On the upper horizontal plane of the square 1 the fixed 5 blade of the scissors is fixed. An axle is fastened to the front side of the square 1, on which a blade 4 located vertically can be raised and lowered. On the upper part of the blade 4, the splitter 5 is fastened. The spring 6 constantly strives to drag the splitter 5, and therefore the blade 4 down, but this is prevented by the left end of the plate 7 entering the notch 8 of the lower part of the blade 4. The plate 7 is horizontal and can move freely back and forth. On the axis of the blade 4 is worn, the STANDING prizhi}, 1 (34

Viy 4 to square 1 for the purpose of exact work of scissors.

If the mechanism is at rest, the blade 4 occupies the upper position, which is squeezed by the left end of plate 7. The chuck 2 has a fixed finger 9, which is loosely fitted with two grids (crests) 10, designed to react to the breakage of the thread, and the bar // to respond to thread tightening. When the machine is working normally, the grgbni 10 is kept running, they are in a horizontal position with cnc-i My lines. The same position is occupied by the bar 11, held by the curved end of the 15th turn of the wire lever 14.

The filaments are held by a curved wire 12 fixed to the top of the chuck 2. The wire 12 also serves to retard the passing filaments. On the front part of the wire 12, the sleeve / 3 is put on the right side, and the sleeve is on the left side 17. Between the 13 VL 17 sleeves on the wire, the turns of the lever 14 and the spiral spring 16 are put on the right. The last end is fastened with the right end and turns of the lever 14, and the left end a sleeve 17. The turns of the lever 14 terminate in a folded end 15, which serves to hold the strip 11 in a horizontal position.

The coupling 17 is provided with a locking screw 18. The coupling of the spring is controlled by the coupling 17.

The press and the device for adjusting it, as well as for turning it on and off (the stand with the chuck, the sleeve, the roller, the column, the press, the nut and the lock nut) are part of the machine. For the automatic shutdown of the press, two prruisins are put on the press roller: front 2 (9-weak and rear 2 / -strong (Fig. 4).

A roller 19 of the press passes through a sleeve, voluntarily in front of the hole of the cartridge and through the hole of the cartridge itself.

The front spring 20 with the front end rests against the sleeve 28, while the salted-into the through washer 22. The rear spring 21 with the front end abuts against the washer 22, the rear-end into the ring 23, and the ring 23 abuts against the pin 24.

The ring 25 can move in the axial direction and compress the spring 21. To the side of the cartridge reinforced squares 25, on the axis of which receives the swinging movement of the latch 26. The right part of the latch 26 goes into the slot in the cartridge. On the left side of the latch 26, the adjustment bar 27 is fastened to regulate the speed at which the press is turned off.

If the press is turned on, i.e. in contact with the needles (presses on the needles), the ring 23 rests on the right side of the latch 26, as a result of which the rear spring 2 / is compressed and presses on the press roller. Simply put, under the action of the rear spring roller introduces the press into contact with the needles. The front spring is also compressed by a strong back spring.

If the press is turned off, the latch 26 is raised, the spring 2 / presses the ring 23, which moves, the spring 20 pulls the roller together with the press back and takes the press out of contact with the needles.

The effect of the adaptation is as follows. When one of the two threaded filaments in any of the intake systems is cut off, the grill 10 is no longer held by the thread, falls off from its own force of gravity and knocks down the notch plate 7c 4. The blade 4 falls down under the action of the spring 6 and is in contact with. Blade 3, cuts off the second thread. At the time of lowering the blade 4, the knocker 5 strikes the bar 27, causing the left side of the latch 26 to lower, and the right, which is an abutment for the ring 23, is raised. In this case, the rear spring 21 is inactive, i.e. it no longer presses on the roller, and the front roller moves the roller together with the press back. It is considered that the system is turned off, the rest continue to work, and there is no gap on the canvas.

The effect of puffing on the quality of the web is eliminated by the mechanism as follows. When one of the two threaded threads, due to pinching it on the bobbin, is tightened, lever 14 is pulled down by the thread, as a result of which the bar // slides off the curved end of the lever 14 and falls down. When falling, the strap // knocks the plate 7 off the notch blade 4.

The subject matter of the invention.
