Definitions
- the invention relates to a flat knitting machine with needle beds, with tongue needles located in needle channels, with at least one combined knitting and shoulder lock, and with a carriage carrying the knitting and shoulder lock, on which a brush holder with a brush for opening the tongues needles in the knitting area of the sled is attached.
- REPLACEMENT LEAF can always be pivoted completely out of the needle area during the transfer process.
- pivoting area for pivoting the brush perpendicular to the direction of slide travel such conventional arrangements are also not completely reliable in their functioning.
- the invention is therefore based on the object of providing a flat knitting machine with a brush holder which, when using a combined knitting and neck lock, can be brought out of the neck area with a simple device, the space required for removing the brushes during the Transfer process small and the distance should be safe and reliable.
- the object is achieved according to the invention in that the brush holder is slidably mounted on the slide parallel to the slide direction.
- the flat knitting machine according to the invention is furthermore distinguished by a very simple construction for the brush holder and for arrangements for parallel displacement thereof to the direction of slide travel.
- the brush holder is slidably mounted on or on at least one rail which is fastened to the slide parallel to its direction of travel.
- stops are provided, against which the brush holder strikes and is carried along by the carriage in the position in which it is moved out of the transfer region during the transfer process.
- the slide has a controllable driver element which detachably engages in a driver device of the brush holder.
- the brush holder can be brought into the knitting position or the hanging position by controlling the driving element, which can be, for example, a bolt that can be extended and retracted.
- the controllable driver element is preferably arranged substantially at the height of the combined knitting and shoulder lock with respect to the direction of slide travel. During the knitting process, ie when the brush performs its function of opening the tongue needles, the control or switchable driver element is brought into the switch position in which the brush holder, due to its own position, is at the level of the combined one Knit and neck lock holds.
- the driver element is preferably switched off during the knitting process and out of function during the transfer process. This means that during the knitting process, in which the driver element is switched to function, it takes the brush holder and thus the brush with it by engaging in the brush holder. If, however, the driver element is switched off during the transfer process, it does not take the brush holder and therefore the brush with it, which means that the brush holder slides out of the transfer area of the lock and cannot interfere with the transfer process.
- the driver element can be controlled or switched in different ways.
- the driver element is preferably switched electromagnetically, for example with an electromagnet, which selectively extends and retracts the driver element.
- the driving or switching of the driver element is carried out mechanically by means of the slide elements provided for the function of the cap lock parts.
- the driver element In connection with the mechanical switching of the cap lock parts into the working position, the driver element is also mechanically switched via corresponding connecting parts.
- the driver element When the cap lock parts are put into operation, the driver element is switched out of function, so that the slide moves parallel to the direction of slide travel from the neck area of the lock.
- a particularly advantageous embodiment of the invention is that the brush holder has an additional brake brush that touches a needle bed or elements attached to the needle bed.
- the brush shark is ter exempt from the controllable driver element.
- the additional brake brush exerts a friction which causes the brush holder to be displaced in the opposite direction to the carriage running direction and thereby slides out of the neck area parallel to the carriage running direction. This is a particularly simple possibility to enable the brush holder to slide out of the neck area without additional means if the brush holder or the associated controllable element is switched accordingly.
- the driver device has at least one hinged folding element.
- a switchable driver element into the knitting position again and again at the end of the carriage stroke, depending on the carriage running direction, regardless of the carriage running direction, so that the brush can perform its function of opening the latch needles during the knitting process.
- This embodiment enables the driver device to function reliably and to be switched from one running direction to the other with the least expenditure on construction and parts.
- the at least one folding element is rotatably mounted in such a way that the driver element which has been brought into operation can reach a driver position and is locked in this. Due to the rotatable mounting of the folding element, switching at the end of the slide stroke is possible automatically and in a simple manner. With the further embodiment, according to which the folding element each has a run-in slope, this switching and / or locking process is further simplified and reliably designed when the slide stroke is reversed.
- FIG. 1 shows a schematic representation of an embodiment for a brush holder according to the present invention in a view seen from the slide
- FIG. 2 shows a cross section along the section line II-II shown in FIG. 1 with indicated slide and needle bed elements
- FIG. 3 a representation that corresponds to Figure 1, but in which the position of the brush holder is shown during the transfer process.
- FIGS. 1 to 3 two rails 2, 3 are mounted on a slide 1 shown schematically in FIG. 2 parallel to the slide running direction S one above the other and parallel to each other.
- a brush holder 4 is slidably mounted on the rails 2, 3 and has a brush which projects vertically downwards and a brake brush 6 which projects obliquely towards the carriage 1.
- the brush 5 is located in the needle region of the needles (not shown) lying in needle beds, as seen transversely to the direction S of the slide.
- the brake brush 6 touches elements 7 which are firmly attached to the needle bed, for example comb boards, and slides over them when the carriage 1 is moved over the needle beds.
- the brush holder 4 can slide between stops 8 and 9 on the rails 2 and 3 parallel to the carriage running direction S. He does this when a driver element 10 is switched so that it does not protrude into a driver device, which in the exemplary embodiments shown consists of two flaps 11 and
- REPLACEMENT LEAF 12 exists.
- the brush holder 4 is moved to the stop 9 because the brake brush 6 slides on parts of the needle bed and is carried along to the stop 9 by the friction of the brush holder 4.
- the brush holder 4 strikes the stop 8 in a corresponding manner and is carried by the latter when the driver element 10 is switched off, ie does not attack the driver device consisting of the folding elements 11 and 12.
- the brush 5 is displaced from the functional area of the combined knitting and neck lock, not shown, and in this case can do not interfere with the transfer process.
- the driving element 10 is brought into a switching position in which it engages in the driving device 11, 12, so that the brush holder 4 and thus the brush 5 remain in the knitting area during the movement of the carriage.
- the brush 5 can therefore perform its desired function of opening the latch needles.
- the folding elements 11, 12 are each rotatably supported about a pivot point 13 and 14.
- the folding elements 11 and 12 have mutually facing projections 15, 16, which in the normal, non-rotated state of the folding elements 11, 12 lie on pins 17, 18 due to the force of gravity, because the pivot points 13 and 14 lie outside the center of gravity the folding elements 11 and 12 are.
- the driver device 11, 12 works in the following way. With the driver element 10 switched to function, i.e. if
- the brush 5 can perform its function of opening the latch needles during the knitting process, since it is carried along by the driver element 10 for as long ⁇ is taken until it is deactivated by pulling it out of the driver device 11, 12.
- the brush holder 4 When the driver element 10 is out of function, the brush holder 4 is moved against the respective stop 8 or 9 due to the friction by the brake brush 6 against the direction of movement S of the slide and thus out of the knitting or transferring area of the combined knitting and the padlock moves. In this position, which is shown in FIG. 3, the transfer process can take place without the brush being adversely affected.
- the brush holder 4 When reversing the stroke, the brush holder 4 is in turn initially held in position due to the frictional force of the brake brush 6, while the rails 2 and 3, which are firmly connected to the carriage 1, are displaced. As a result, a relative movement occurs between the driver element 10 and the brush holder 4. If, as shown in FIG.
- the slide stroke to the right has ended and the slide stroke to the left now begins, the brush holder 4 remains in this position with respect to the needle bed, while the driver element 10 with the slide moves up to the left the folding element 11 of the driver device of the brush shark ters 4 moved.
- the driver element 10 slides onto an inclined lower edge 19 of the folding element 11, as a result of which it rotates about the pivot point 13 and comes into the rotational position shown in dashed lines in FIG.
- the driver element 10 reaches the vertical inner edge of the other folding element 12 when the driver element is switched to the position for the knitting process. Since - as already stated - the flap element 12 cannot rotate, the brush holder 4 and thus the brush 5 are taken along and are located in the knitting area of the combined knitting and shoulder lock for opening the tongue.
- the folding element 11 rotates back about the pivot point 13 into the starting position.
- the entrainment element 10 is part of a entrainment device 21 which is fastened with a screw 22 to the side of the carriage 1 facing the brush holder 4.
- a leaf spring 23 presses the driver element 10, which is designed as a bolt, away from the brush holder 4 and in this case is disengaged from the driver device 11, 12. Because of the brake brush 6, the brush holder 4 and so that the brush 5 moves out of the knitting and neck area of the combined knitting and neck lock. This switching state of the driver element 10 thus corresponds to the transfer process. If, on the other hand, the driver element 10 is pressed outwards from the lock side towards the brush holder 4, the bolt engages the driver device of the brush holder 4 and, as described, takes it along. The brush 5 is therefore in the knitting position in this case.
- the driver element 10 can be actuated in various ways.
- the driver element 10 is connected to the armature by an electromagnet and is moved by corresponding energization of the electromagnet.
- the driving element 10 is released and, due to the spring action of the leaf spring 23, is rendered inoperative, so that the brush holder 4 and thus the brush 5 are moved out of the transfer area becomes.
