Definitions

  • the invention relates to a knitting cam for a flat knitting machine or warp knitting machine with a guide cam part arranged in the edge region of the knitting cam. Furthermore, the invention relates to a flat knitting machine or warp knitting machine and a method for operating a flat knitting machine or warp knitting machine.
  • the needles selected for this purpose must be brought into a defined, advanced position. Then the carriage takes a position outside the knitting or needle bed area. For this purpose it is known to provide a special lock at the end of the carriage, which brings selected needles out into an advanced position. Since the lock has no trigger parts, normal knitting functions cannot be performed. Incoming, only the needles advanced before the carriage reversal can be processed and retracted.
  • a knitting cam for a flat knitting machine or warp knitting machine with a guide cam arranged in the edge region of the knitting cam, the guide cam having at least two guide cam sections and at least one guide cam section being switchable between an active position and an inactive position.
  • the at least one partial guide lock section for an inactive position is in an in Placed towards lock plate lowered position, or in, under or over another lock part, in particular another guide lock part section, and thus switched to inactive.
  • the guide cam section When the guide cam section is lowered, it can be at least partially sunk into the cam plate.
  • the guide lock part section is arranged in an active position at a distance above the lock plate, ie there is "air" between the guide lock part section and the lock plate.
  • the guide lock subsection can be lowered for an inactive position so that the distance to the lock plate is reduced, no longer exists, i.e. the underside of the guide lock subsection is level with the lock plate, or the guide lock subsection is at least partially sunk into the lock plate.
  • the guide cam section is shifted for an inactive position, in particular is moved parallel to the upper side of the lock plate, it can be shifted into, over or under another lock part, in particular another guide cam section.
  • the other cam may have a pocket in which the displaced guide cam portion may be received.
  • the guide lock part can have three guide lock part sections.
  • at least one guide slit section be switchable. It is thus possible, for example, to form a channel between the two other guide lock subsections by inactivating one guide lock subsection. In particular, this makes it possible to keep the control feet separate from inserts that have been advanced and from inserts that have not been advanced. This supports the reliability of the knitting process.
  • a guide cam section can be provided for stabilizing control butts of knitting needles when they pass through a cam track formed by another guide cam section.
  • a trigger part is provided, with a pusher part being arranged below the trigger part, which is also arranged at the same level as a pusher part provided to form a tuck loop. If a take-off part is provided, the usual, normal knitting functions can be performed. By providing a further additional pusher part in the area of the trigger part, however, it is possible to prevent the control feet of insert parts that have assumed a pushed-for position from being pulled off the trigger part. Thus, the inserts remain in an advanced position and warp thread applications can be carried out.
  • a presser part In the case of knitting locks, a presser part is often already provided in the area of a take-off part, but this is located on a different track than a presser part, which is provided for forming a tuck.
  • two pusher parts are therefore preferably provided below a trigger part.
  • a pusher part in the area of the trigger part can be used to prevent the insert part from being pulled off, so that the insert part remains in a pushed-forward position.
  • a flat knitting machine or warp knitting machine with a knitting cam according to the invention also falls within the scope of the invention.
  • the scope of the invention includes a method for operating a flat knitting machine or warp knitting machine, in which one or more inserts, in particular knitting needles, of a front needle bed and/or one or more inserts, in particular knitting needles, of a rear needle bed for a warp thread application ends in a defined cam advanced position are brought and then a thread is introduced into the advanced inserts.
  • a pusher part can be provided which prevents the advanced inserts from being pulled off.
  • a guide lock part can have a guide lock part section that can be switched inactive, so that an additional lock track is created and a withdrawal of the inserts at this point is avoided.
  • a switchable handle part can lift the correspondingly selected insert parts out of the lock curve via a trigger part and thus prevent the insert parts from being removed.
  • a section of the respectively trailing guide lock part be switched inactive, whereby the inserts are moved along the additional cam track created thereby.
  • the selected inserts can thereby remain in their advanced position, allowing warp threads to be inserted into these inserts.
  • the inserts to be advanced in particular knitting needles, can be selected and advanced in the needle bed via a cam cam. Then, depending on the switching position of a presser part and depending on the selected selection track, a tuck loop or a stitch can be formed with the inserted inserts. Thereafter, the inserted inserts can, as already explained above, be lifted by an activated pusher part over a trigger part, so that they get into a lock track.
  • a cam track can be created on the incoming side of the cam by removing a guide cam section. In particular, this can prevent the advanced insert parts from being pulled off as they enter the lock.
  • a pusher part can be activated when entering the lock in order to lift the control feet of the advanced insert parts over a trigger part. This makes it possible for the control butts of the corresponding inserts to subsequently reach a lock area with which a knitting operation can be carried out.
  • a further pusher part is activated when closing the lock, in order to control the butts of the advanced insert parts via a further one to lift the trigger. The advanced insert parts can thus also remain in an advanced position when entering the lock.
  • control feet are kept separate from inserted parts that have been advanced and from inserts that have not been advanced by a partial guide lock section.
  • the method according to the invention it is possible in particular to drive out all needles or areas of needles or individual needles of the front and/or rear needle bed for warp thread applications into a defined, advanced position. There is also the possibility, after the carriage has been reversed, to process and crotch the needles driven out for warp thread applications.
  • One or more additional cam tracks for the needles or other insert parts of the needle bed can be created in that the guide cam part is designed to be switchable in sections.
  • the guide lock part(s) can be made in several parts.
  • the conventional handle part control can have an additional switchable handle part on the lock-outgoing and/or on the lock-incoming side of the lock, which makes it possible to lift the advanced insert parts via a trigger part.
  • the 1 shows a knitting cam 100 as part of a knitting system not shown in detail.
  • the knitting cam 100 comprises a guide cam part 1, trigger parts 3, presser parts 5 arranged in the region of the trigger parts 3 and a presser part 4.
  • the trigger parts 3 and the presser parts 4, 5 are usually present on knitting cams.
  • These lock parts are used to drive out and pull off inserts, in particular knitting needles, for the production of knitted goods and to hold the inserts in comb level.
  • the pusher parts 4, 5 are used to crush selected control feet of the inserts.
  • the guide lock part 1 has guide lock subsections 1a, 1b, with the guide lock subsection 1b being switchable in the exemplary embodiment shown.
  • the guide lock part section 1b can be lowered in the direction of the lock plate 7 or in, under or over another lock part, e.g. the guide lock part section 1a.
  • the guide cam section 1a is fixed, i. H. not arranged to be movable relative to the lock plate 7 .
  • a switchable guide cam section 1a, 1b can be lowered or switched by means of slides, levers, motors, magnets, hydraulically or pneumatically.
  • an additional, also switchable presser part 2 is provided according to the invention on the outgoing side of the switchable presser part 4 for catching.
  • the control foot of a selected insert are pressed into the needle bed, not shown here, and are thus lifted out of the cam cam via the trigger part 3, which prevents the selected insert from being pulled back or crooked.
  • Pusher part 2 is on the same track as pusher part 4 for capture. Like the trigger part 5, it is also located below the right-hand trigger part 3.
  • the 2 essentially corresponds to the 1 with the difference that the guide cam part 1 has three sections.
  • the guide lock subsections 1a, 1b are again provided, with the guide lock subsection 1b being designed to be switchable.
  • a guide cam section 1c is provided. When the guide cam section 1b is lowered, a channel 11 is formed between the guide cam sections 1a, 1c.
  • the guide cam section 1c allows the control feet of inserts that have an advanced position to be kept separate from the control feet of inserts that do not have an advanced position. The control butts of inserts that do not have an advanced position move along the underside of the guide cam portion 1c.
  • the 3 shows the possible path F (solid line) for catching formation and subsequent expulsion for warp thread insertion of control butts not shown here of inserted parts during stitch formation in a lock 100 corresponding to the invention.
  • the carriage movement direction is in the 3 represented by the arrow L.
  • the selected control butt or the selected control butts first pass the exit cam part 6, as a result of which the inserts are advanced out of their same comb position in the needle bed.
  • the control butts of the selected inserts are pressed into the needle bed by means of the presser part 4 for catch. So first tuck loops are formed here with these inserts.
  • the control butts are also pressed into the needle bed by the additional switchable presser part 2, as a result of which they cannot be pulled back by the subsequent trigger part 3.
  • the trailing guide cam section 1b is switched to an inactive position, ie lowered.
  • the control feet are guided through the additional lock track Z.
  • the selected inserts remain in their advanced position and can be used for warp applications.
  • the selected control butts pass the exit cam 6, as a result of which the inserts are advanced from their same comb position in the needle bed. Stitches are formed here first.
  • the control butts are pressed into the needle bed by the lock-exiting presser part 5, as a result of which they cannot be pulled back by the trailing trigger part 3.
  • the trailing guide cam section 1b is switched to an inactive position.
  • the control feet are guided through the additional lock track Z.
  • the selected inserts remain in their advanced position and can thus be used for warp thread applications.
  • presser feet of the inserts are on a different track, which is why presser part 5 was used instead of presser part 2.
  • Stitch formation with subsequent expulsion for warp thread insertion can also be achieved via the other selection track by switching the presser part 4 for tuck into its inactive position and using the presser part 2.
  • FIGS. 4a, 4b show possible variants for the formation of tuck loops and stitches in combination with the driving out of inserts into a position for warp thread applications.
  • the path F along which tuck loops are formed is shown as a solid line.
  • the path MB on which stitches are formed is shown as a broken line.
  • the control butts of the inserts that were selected for tucking are pressed into the needle bed by means of the presser part 4 for tacking. With these inserts, tuck loops are formed first. In the further course of the path F, the control butts of the inserts are pressed into the needle bed by the switchable presser part 2, as a result of which they cannot be pulled back by the subsequent take-off part 3. In this case, the trailing guide cam section 1b is switched to an inactive position. The control feet are guided through the additional lock track Z. The selected inserts remain in their advanced position after tuck formation and can be used for warp thread applications.
  • the control butts of the inserts selected for stitch formation are not pressed into the needle bed by the presser part 4 and the selected inserts are driven out for stitch formation, according to the path MB.
  • the pusher part 5 is switched to its inactive position and does not apply pressure to the control feet.
  • the control butts come into contact with the trailing take-off part 3 and are taken off by this into the predetermined quilting depth for stitch formation. This control feet are so out below the guide lock part 1 on its underside.
  • control feet of the inserts that were selected for catching formation (path F, solid line) in pressed the needle bed. Tuck loops are formed with these inserts.
  • these control butts are not pressed into the needle bed by the additional switchable presser part 2, which has been switched to inactive for this purpose. As a result, the control butts come into contact with the trailing trigger part 3 and are pulled by this into the specified sinking depth. The corresponding inserts can therefore no longer be used for a warp thread application.
  • the control butts of the inserts selected for stitch formation are not pressed into the needle bed by the presser part 4 and the selected inserts are driven out for stitch formation (path MB, dashed line).
  • the additional switchable pusher part 5 is switched to its active position and acts on the control feet.
  • the trailing guide cam portion 1b is switched to an inactive position.
  • the control feet are guided through the additional lock track Z.
  • the selected inserts thus remain in their advanced position after stitch formation and can be used for warp thread applications.
  • the guide lock part section 1c keeps the control feet securely separated from inserts in an advanced position and from inserts in a retracted position.
  • the Figures 5a to 5d show the knitting cam 100 after a carriage reversal.
  • the carriage and thus the knitting cam 100 now move in the direction of the arrow R.
  • control butts of the insert parts which were driven out to insert the warp thread, are moved after the carriage reversal in the cam track Z formed by the guide cam part section 1b and then lifted over the take-off part 3 by means of the additional switchable presser part 2 and brought into the cam track for stitch formation. A stitch is then formed again (path MB, dashed line).
  • the control butts of the inserts which are on comb level and have not been selected for warp thread insertion and driven out accordingly, also form a stitch after the carriage reversal (path MB, solid line).
  • the 6 shows the possibility of withdrawing the inserted parts, which have been pushed forward to the warp thread insertion, after the carriage has been reversed, entering the lock into the basic position.
  • the 7 1 shows a symmetrically designed knit cam 100.
  • the guide cam sections 1a, 1b, 1c and the additional switchable presser part 2 can be provided on both sides of the cam 100.
  • This configuration of cam 100 allows the needles selected for warp insertion to remain in position even during normal operation of cam 100 for stitch formation.
  • the guide lock part sections 1b were at least partially countersunk, so that corresponding lock tracks Z are created, through which the feet of inserts are guided.
