Description

Title of the invention

Knitting machine, in particular flat knitting machine

Field of application of the invention

The invention is applicable to knitting machines, in particular flat knitting machines with at least one pair of needle beds and knitting carriages in one direction with a cam lock part for forming tuck loops, a switchable cam lock part for knitting, a styling part and one for transferring stitches of needles of one needle bed onto the needles the other needle bed serving transfer and takeover castle as a multi-part, partially switchable return lock ·

Known is a knitting machine of the type described above in which the transfer and the takeover lock and the partially switchable return lock are arranged on the provided for mesh transfer knitting carriage respectively behind the Kulierteil. The selected for mesh transfer needles are first expelled to catch and then laterally on the Kulierteil Vorüberbewegt without influenced by this v / earth »After passing the part, these needles are driven out through the mesh transfer lock in transfer position and then withdrawn from the return lock in the basic position ·

The provided for mesh transfer needles are driven out of the basic position in takeover position only after passing the part by the takeover, before they are deducted from the return lock back to basic position »

The disadvantage of this machine is that such a lock assembly is space consuming and requires large knitting slides and long slide passages, which significantly limits the performance of the machine.

Aim of the invention

It is therefore the object of the present invention to significantly increase the performance of the flat knitting machine with revolving carriage, in particular in the production of overhanging patterns.

statement

The invention is based on the object of knitting machines of the type mentioned a considerable shortening dear knitting carriage by using a space-saving lock system.

This object is achieved in that the Austriebsschloßteil are formed to form tuck loops as takeover lock and part of the return lock as a culmination, the transfer lock above the lock part to form tongs arranged and a switchable Schloßweiche before the Austriebsschloßteil to form Fanghenkeln and the transfer lock is provided. In a further embodiment of the inventive concept, the return lock further consists of a stationary lock part for the withdrawal of the transferring needles from the transfer position to approximately at catch level and arranged between the stationary lock part and the Kulteiil, for further deduction of the transferring needles switchable lock part.

According to a further feature of the invention, the intermediate switchable lock part is designed to be pivotable.

According to yet another feature of the invention, the transfer lock consists of a stationary drive lock part and the actual, height-adjustable transfer lock part with cover part.

Advantageously, a stationary cover part is provided above the interposable Austriebsschloßteiles for knitting.

According to a further feature of the invention is between the switchable Schloßv / oak and the Austriebsschloßteil z.um forming tongs a height-adjustable lock with cover part for lifting the receiving needles in Vorbe preparation of UmhängeVorganges arranged.

According to a final feature of the invention, the switchable lock switch is designed to be retractable.

Version, g; s pe eep el

The invention described above will be explained in more detail below with reference to an embodiment «The single figure of the accompanying drawing shows two identically formed lock systems for the two needle beds of the knitting machine according to the invention.

Each lock system is provided with a cam lock member 1 for forming tuck loops, an engageable cam lock member 2 for knitting, a styling member 3a, and a transfer cam 4a serving to transfer stitches of needles from one needle bed to the needles of the other needle bed; b; c and a corresponding takeover lock and a multipart, partially switchable return lock 3a; b; c provided ·

According to the Austriebsschloßteil 1 is now also formed as a takeover lock for forming tuck loops and the Kulierteil 3a a part of the return lock 3a; b; tf so that it can both be used for stimulating and for returning

The needles are provided after the stitch transfer or picking. For selecting the needles between the stitch transfer and the picking track for pang or knitting, a retractable camshaft 5 is arranged in front of the stationary ejection cam 1 for forming pangles and the stationary ejection cam 4b of the stitch mount , At the stationary part 4b of the transfer lock, the actual, height adjustable trained transfer lock part 4a connects to which a cover part 4c is assigned. Furthermore, a stationary cover member 6 is provided above the switchable for knitting Austriebsschloßteiles 2, and between the switchable Schloßweiche 5 and the Austriebsschloßteil 1 for forming Fanghenkeln in a conventional manner, a height-adjustable lock part 7 with cover part 8 for lifting the acquiring needles in preparation for the Umhängevorganges arranged "

When running the knitting carriage on the Nadelbettenpaare (arrow) öntscheiä.et the state of the Schloßweiche 5 either between a stitch transfer or the mesh takeover or the expulsion of the needles 9 »10 in Pang or knitting position. If the switch 5 is in the lock channel, the needles 9 reach the transfer position via the knock-out part 4b of the transfer lock. The not selected for mesh transfer needles 10 of the opposite needle bed are initially expelled slightly by the cam 7, so that the head of the receiving needles 10 just below the needle shaft of the transferring needles 9, before (the needles 10) through the Austriebsschloßteil 2 so be far advanced that they pierce the widened stitches of the opposite needles 9. The transferring needles 9 then pass through the shape of the transfer part 4a in a position with less, the needles somewhat relaxing budding. ·

After a short settling time, the transfer of the transferring needles 9 takes place through the stationary return cam 3c and further a time-differentiated removal of the transferring needles 9 and the receiving

Needles 10 through the pivotally formed return cam 3b. Finally, a final return to the basic position, which is effected in the case of the receiving needles by the Kulierteil 3a.

In order to achieve patterning effects in the mesh transfer, a selection system may be present that the need for handover certain needles 9 are pressed in front of the camshaft 5 in the needle bed, so that they are not detected by any Austriebsschloßteil v / earth and therefore remain in the normal position.

To form fishing patterns and for knitting (not shown), the oak 5 is sunk at both lock systems of the knitting carriage, and the needles are then driven out over the raising cam parts 1 and 2 to the catching or knitting height and then through the cropping section 3a withdrawn again to the basic position, wherein the pivotable return cam 3b is ineffective (see lower lock system).

It is obvious that the return cam portion 3b instead of pivoting could also be designed to be retractable, such as, for example, the Schloßweiche 5 or the Austriebsschloßtöil. 2
