j Double cylinder circular knitting machine

The present invention relates to a double cylinder dog knitting machine chine for the manufacture of hosiery,. especially those with closed ones directly on the machine Tip, whereby the machine is equipped with a compressed air source to pull off and transport the knitted fabric The knock-off point in the needle cylinder is provided out of the machine, while turning the knitted fabric over at the same time while avoiding twisting of the knitted fabric, e.g. by a hotation basket, which the knitted fabric after dropping catches by the cylinder needles.

Circular knitting machines are known which have a device are equipped to convey the knitted fabric from a rotating basket into a container - and especially on double-cylinder knitted automobiles in the manufacture of

One of the known devices for conveying a • Knitted fabric from a liotation basket into a £> ai, uiielbehält it consists in that one through the interior of the Uadelzylirider drawn off via a pipeline into the ionization basket Knitted fabric into the collecting container by compressed air is conveyed via an iiohrleitung that connects to the other side of the rotating basket.

These and other devices working on a similar principle can be used successfully with dog knitting machines which knit in the lower drawer 1 cylinder peel off. In circular knitting machines, where it is advantageous to place the knitted fabric in the upper needle cylinder to be deducted, e.g. when making stocking knits with closed tip directly on the L'aschiie, this is Arrangement unfavorable because it enlarges the engine house and Haun around the needle cylinder heruo einniuiut, whereby the clarity and storage; - · the li machine verses c hlec ht

Two coaxially arranged needle cylinders 1.2 are provided with aligned longitudinal grooves J for the storage of JJoppelz ungennadeln 4, on which a knitted fabric 5 is formed - ^ he upper needle cylinder 2 is on hills 6 in an upper stationary flange 7 and the lower needle cylinder 1 likewise on balls 8 in a lower stationary flange 9 of the machine frame rotatably mounted, whereby both needle cylinders 1,2- are secured both radially and axially, on the upper Hadel- ' cylinder 2 is fastened by a spring wedge 10 and a nut 11, a gear 12, which with a driving Gear 13 is in constant engagement. Pas driving Gear 13 is by means of a pin 14 with a vertical shaft 15 firmly connected, which are rotatably supported by bearings 16 in the upper flange 7 and in the lower flange 9 is. On the lower needle cylinder 1 is wedge by a spring ^ 17 and a nut 18 attached a gear 19, which is in constant engagement with a driving gear 20. The driving gear 20 is with a pin 21 firmly connected to the vertical shaft 15, which by a transmission, not shown, is driven. A Hohr 22 is connected to the lower needle cylinder "1, which is carried by a bracket 23 fastened to the lower flange 9 by means of screws 24. In one of the locations the .Rohres 22 determining version of the console 23 is located a pin 25 on which a flap 26 is pivotably arranged is. This flap 26 assumes a position in which it acts on the mouth of the tube 22 as a result a spring, not shown, closes. A collecting container stands on the floor under the mouth of the pipe 22 27 for the finished knitted fabrics.

A hotation basket 28 is connected to the upper needle cylinder 2 , firmly connected, which at its - ^ ode and circumference with openings 29 is provided. On the circumference of the rotating basket 28, a ring 30 is attached, which for receiving a Flap 31 is used. On the upper, fixed paddling 7 is a holder 32 for supporting the tubular mouth a -tHichse 33 attached, this sleeve 33 itself the -i-iotation basket 28 encloses the same axis and by a Seal 34- is connected to the upper needle cylinder 2. On the tubular Mhdung the sleeve 33 is a hose 34 'raised, the other end of which is attached to the socket of a Air distributor 35 is connected. On a tenon 36 this air distributor 35 is a flap in its chamber 37 arranged, the rotation or change of their position by a Schalttromniel, not shown iiundstrickm-3sc "-! ine. Opposite the neck of the air distributor 35> to which the hose 34 'is connected is, there is also a nozzle which opens into the free atmosphere. Another two opposite nozzles of the air distributor 35 are hoses 38 and 39 connected so that the other end of the Tube 38 with the suction opening and the other end of the Hose 39 with the pressure opening of a fan 40 connected is. This fan 40 is driven by a V-belt 4-1 driven by an electric motor 42.

How the double cylinder circular knitting machine works is the following:

When forming a knitted fabric 5 ^o f the cylinder needles is dac knitted fabric in the interior and generous 5; drawn -to the upper Nadelzyli DERS. 2 The flap 37 of the air diffuser 35 takes one out of J? Ig. 1 ersicnttLidH ^i: # position a while

the flap 26 closes the mouth of the tube 22 at the same time, air is drawn into the haum of the luaschenabschlagplane ^: sucks and flows in the direction of arrows through the interior of the upper needle cylinder 2, rotation basket 28, -tnichse;> 3, -ochosel 34 *, air distributor 35 and fan 40 to the atmosphere. After the end of the joint: it is sucked into the rotary basket 28.

In a further phase, the flap 37 of the air distributor 35 rotates into one made of Pig due to the pulse of the switching drum (not shown). 2 apparent position. The air sucked in by the fan 40 from the atmosphere into the air distributor 35 flows in the direction of the arrows back into the air distributor 35 and through the interior of the hose 34 ', sleeve 35, through the rotating basket 28, both needle cylinders 2 and 1 and Kohr of 22 in the atmosphere, wherein the flap is swung out 26 by the air pressure around the pin 25 from the mouth of the tube 22 away and, therefore, the mouth of the ro oves 22 remains open. The finished knitted fabric 5 is blown out of the xiotatious basket 28 through the interior of both needle cylinders 2 and 1 and the tube 22 into the collecting container 27.

The double-cylinder circular knitting machine according to the invention can also have various design modifications, for example, when the finished knitted fabric 5 is transported ^{from the} rotating basket 28 into the ^o aiamelbeb .-: older 27, this knitted fabric 5 can be sucked out of the obation basket 28 by the fan 40, which to which iiohr 22 is connected, and the rotation basket 28 does not have to be placed directly on the upper needle cylinder 2 either.
