Definitions
- the invention relates to a warp knitting machine with pointed needles and a sample press that is a powered Press bar and individually controllable press elements has that it during the working stroke of the press bar optionally a press contact with the hook of the associated Exercise pointed needles or not.
- DE 44 18 714 C1 describes a laying bar of a warp knitting machine known, with the laying needles at the free End of a variety of piezoelectric bending transducers are attached, the bending transducer on one side the laying bar are clamped. Through electrical control the bending transducer takes one each laying needle from two positions specified by stops. This allows a sample of the goods.
- the invention has for its object the sample press a warp knitting machine of the type mentioned kind of improve.
- Each pressing element has a piezoelectric clamped on one side Bending converter is assigned, its free End in the direction of the needle contour from a first position, in which a press contact occurs during the working stroke, in a second position in which the pressing element or a upstream power transmission element in Direction of the needle contour is displaced is.
- the working stroke is from the press element transferred to the hook of the pointed needle, in the second position, on the other hand, moves because of the deflection the pressing element next to the pointed needle respectively an upstream power transmission element in addition a downstream power transmission element.
- the one to be covered by the free end of the bending transducer Way is very short. This allows high working speeds, which is supported by the fact that a piezoelectric bending transducer the control commands very follows quickly. The design effort is also low.
- the bending transducers can be placed side by side with a smaller distance arrange so that each pointed needle is a bending transducer can be assigned.
- a preferred alternative is that the piezoelectric Bending converter attached to the press bar is and at the free end with a lever Press element is coupled, the lever on the Press bar is stored.
- the lever By using the lever the bending transducer is not loaded by the pressing force. It can therefore be made weaker and therefore narrower become.
- the pressing element is a guided one Sliding piece is the piezoelectric bending transducer is attached to the press bar and its free Align the end in the first position with the sliding piece and in the second position relative to the sliding piece is offset. Let through such sliding pieces the hooks of the pointed needles meet very precisely.
- the pressing element is a guided sliding piece
- the piezoelectric bending transducer on one machine-fixed carrier is attached and its free End is provided with an extension into a Longitudinal groove of a lever mounted on the press bar grips and this in the first position with the sliding piece aligns and relatively in the second position offset to the sliding piece.
- the bending transducers not burdened by pressing forces. Since they're on are attached to a machine-fixed carrier the electrical leads also no loads through the working stroke.
- the pressing element is preferably in a longitudinal slot guided sliding piece. Leave the slots align yourself precisely with the pointed needle.
- the guides are expedient for several sliding pieces each grouped into a management segment. Repairs can therefore be carried out by removing and Easily replace such a segment.
- plastic caps one have projecting side wall over its end face. This side wall serves to separate neighboring ones Pressing elements.
- the warp knitting machine of FIG. 1 has a machine frame 1 with a main shaft 2 that over a Lever 3 a needle bar 4 with pointed needles 5, over a Lever 6 a board bar 7 with inclusion tee boards 8, a press bar 10 with a lever 9 a bending transducer control device 11 and one Lever 12 drives bars 13 and 14 with laying needles 15.
- a sensor 16 generates the angle of rotation of the Main shaft 2 corresponding rotation angle signal that one Pattern generator 17 is supplied. This gives accordingly the desired pattern via line 18 control commands to the bending transducer control device 11.
- As a result which is a selection of pressing elements 20 against the Hook 12 of the pointed needles 5 pressed, as is the case in detail will be described below.
- the bending transducer control device 21 of FIG. 2 are strip-shaped piezoelectric bending transducers 22 clamped at one end 23 and with the press bar 10, which performs the working stroke 24, connected.
- the free end 25 of the bending transducer 22 is directly with a pressing element 26 connected.
- the press element is located 26 in its first position, it hits the Working stroke 24 on the hook 19 of the needle 5 and closes the hook space, so that with help the board 8 a stitch can be knocked off.
- the free end 25 will move slightly towards the needle contour, i.e. perpendicular to the plane of the drawing, the pressing element 26 goes between adjacent ones Point needle 5 through without touching it.
- the bending transducers 22 are combined into segments 27, which also carry stops 28 which are the first and precisely define the second position of the free end 25.
- the bending transducer control device has 31 bending transducers 32 on that again firmly clamped at one end 33 and with the Press bar 10 are connected.
- the free end 35 of the bending transducer 32 is with a press element designed as a lever 36 connected.
- This lever is over a bearing 37, which is offset towards the clamping end 33, at the Press bar 10 stored.
- the bending transducers 32 at the working stroke 34 no pressing forces are transmitted.
- the pressing element 36 on the Hook the needle 5 while the pressing element 36 in the second position of the free end of the bending transducer 32 is guided past the needle 5.
- the bending transducer control device has 41 bending transducers 42, the its end 43 firmly clamped to the press bar 10 are.
- the free end 44 can assume two positions which are predetermined by stops 45.
- In the first Position is a pressing element 46 in the form of a Sliding piece pressed against the hook 19 of the pointed needle 5.
- the free end 44 goes in the second position laterally past the press element 46 when the press bar 10 performs the working stroke 47.
- the pressing elements 46 are guided in the longitudinal slots of a guide segment 48, which is held on a machine-fixed carrier 49 becomes.
- On the press bar 10 there is a driver 50 trained bar attached with a return stop 51 cooperates on each slide 46 this back into the starting position during the reverse stroke bring to.
- the bending transducer control device 61 with its end 62 on a machine-fixed Carrier 63 clamped.
- the free end 64 engages with a projection 65 in a longitudinal groove 66 Lever 67, which is pivotable about a pivot point 68.
- the lever 66 on the pressing element 71 passed by.
- the bending transducer control device 81 of FIG. 6 differs differs from that of FIG. 4 in that a lever is provided as a pressing element 82 which by a machine-fixed axis 83, which is parallel to the needle contour, thus perpendicular to the plane of the drawing, pivotable is.
- FIG. 7 and 8 show an arrangement similar to FIG. 4.
- a number of piezoelectric bending transducers 92 are combined into a bending transducer segment 93, which as Whole removed from the press bar 10 and attached to it can be.
- a guide segment 96 is provided in each case can also be handled as a whole.
- the free ends 97 of the bending transducers 92 move between two stops 98 and 99 so that they occupy either position a or position b can.
- Each bending transducer 92 is with a plastic cap 100 provided, one over the end face 101 has protruding side wall 102. With the The end wall can be a pressing element 95 in position a get picked up.
- the side wall 102 ensures that always a sufficient distance from the neighboring press element remains.
- FIG. 9 and 10 show the working area again the pointed needle 5.
- a designed as a sliding piece Pressing element 110 is in the slot 111 of a guide segment 112 led. This leadership segment is in one machine-fixed part attached.
- the press member 110 carries a plastic cap 113 at the front end that the needle material is gentle and has a noise-reducing effect. From Fig. 10 it can be seen that the first, third and fifth pressing element 110 has reached the pressing position and makes a press contact. against this are the second and fourth pressing elements 110 remained in their rest position and do not press contact.
- the Pressing elements shifted slightly to the side so that they glide past the needle 5.
- the Press bar results between the Press bar and the press elements one of several Power transmission elements existing power transmission chain.
- the pressing element is not on the side relocated, but one of the preceding power transmission elements, for example the bending transducer 42 or the lever 67 to avoid a press contact.
