Definitions
- the invention relates to a Mehrnadelkettenstichnähmaschine with a plurality for receiving each of a needle thread leading provided needles, wherein the plurality of needles along a straight line spaced from each other and are movable synchronously with each other, and the line is aligned at least substantially orthogonal to the intended feed direction of a Nähguttransports yarn guide for the plurality of upper yarns for guiding each upper yarn from its yarn supply to the needle associated therewith, with a plurality of driven grippers each for guiding a lower yarn, the grippers being spaced apart and movable synchronously with each other by the movements
- the gripper and the needles in each case an upper and a lower thread are entwined with each other, thereby at the same time several mutually parallel seams in the fabric, with in the feed direction of the fabric without offset each other in the fabric ang eordnete puncture sites of the needles to produce and at least one motor having drive means, with the puncturing movements of the needles and the
- Chainstitch seams are frequently used in the industrial production of sewing articles, among other things for seams of trousers, in particular jeans. Chainstitch seams, in contrast to lockstitch seams, have a higher elasticity, which is why chainstitch seams are often preferred for such applications. In jeans and other denim apparel, but not just denim, parallel and spaced seams are provided, such as double or triple seams.
- crossline machines Two different types of machines have become known.
- One of the two machine types is called a crossline, the other machine type an inline chain stitch machine.
- the two types of machine differ mainly in the arrangement of the plurality of needles to each other and in relation to the intended feed direction of the material transport.
- crossline machines the multiple needles are arranged along a line that is in the fabric transport direction
- CONFIRMATION COPY an angle other than 90 °, usually an acute angle; for example 45 °. Due to the offset of the needles relative to one another in relation to the intended material transport direction, this type of machine is particularly suitable for applications in which the needles can also have a small distance from one another with respect to the material transport direction. In this type of machine due to the principle-related offset of the stitch pattern tools in the seaming direction, the risk is low that threads are detected by adjacent stitch pattern tools and thus result in Nahtschreibigeen.
- the invention is therefore based on the object to provide a sewing machine which is able to produce in a single operation parallel to each other running chain stitches which have a small distance from each other and in which the puncture sites of the seams with respect to their longitudinal direction have no offset from one another ,
- a Mehrnadelkettenstichnähmaschine with the features of claim 1.
- An "additional thread tension” here can be understood as meaning a thread tension portion which, due to the action of the thread tightening means, at least temporarily results on the thread or threads and which adds up to a thread tension possibly present even without such thread tightening means.
- needle spacings of adjacent needles of inline multi-needle chain stitch sewing machines can be provided than hitherto.
- These needle spacings may be selected from a range of 4.4 mm to 2.6 mm, preferably from 4.2 mm to 2.8 mm, and more preferably from a range of 3.8 mm to 3.0 mm.
- the at least one thread tightening means may preferably be arranged between the thread brake and the thread take-up lever (thread take-up). At this point, the intended Fadenanyak can perform particularly effective and reliable.
- a particularly advantageous embodiment of the invention can provide that only one common thread tightening means is provided for the upper threads of a plurality of needles, preferably for all needles.
- the this only one Fadenanzugsstoff associated with a plurality of upper thread should be located in an area of action of Fadenanzugsstoff or out, so that the Fadenanzugsstoff can act on the upper threads for a thread suit.
- the plurality of upper threads are passed through the only one Fadenanzugsstoff.
- the thread suit can be realized in a particularly economical manner.
- the thread tightening means may be passively movable to exert a force on the at least one upper thread.
- the design as a passively moving element complex drives for the Fadenanzugsstoff can be avoided.
- the existing in the upper threads thread tension can be used to make different thread suits in different Stichchanephasen. In addition, this can be done with little effort an automatically performed reset the Fadenanzugsstoffs.
- the Fadenanzugsstoff is designed as a mechanical spring element, or as a pneumatically acting element or as a cam-controlled element which is movably coupled to a drive device of the sewing machine.
- the thread tightening agent during a stitch forming phase ie from the top dead center of the needles to the top dead center by the needles, at least two, preferably at least three, at least local maximum values exerted by the Fadenanzugssch on the at least one upper thread Strength, goes through.
- These multiple local maximums can be different sizes or the same size.
- the thread tightening means repeatedly reaches at least local minimum values of the force exerted by the thread tightening means on the at least one upper thread during a stitch forming phase. These minimum values may also have different values or be the same size.
- a new stitching operation begins, with the loops formed in the immediately preceding stitching operation still resting on the grippers, and the grippers beginning their backward movement, during which the previously formed needle thread loops are released by the grippers due to the backward movement.
- a thread tightening can affect about the beginning of the gripper backward movement beneficial.
- the Oberfadenschiingen can be kept taut to the intended jump of the grippers and thus small enough.
- the force exerted by the thread tightening means on one or more upper threads can then have at least local minimum values when the needles are between their upper and lower dead centers.
- the minimum values of the thread tightening means can be provided in particular when the needles penetrate into the sewing material and / or leave the sewing material again.
- the loop stroke is reduced in comparison to previously known loop stroke values. It has proven to be advantageous if the looping stroke has a value from a range of 4 mm to 2.5 mm and preferably from a range of 3.5 mm to 2.7 mm.
- the distance between a bottom dead center of the respective needle and the position along the longitudinal axis of the needle can be understood as a "ski stroke", at which the gripper intersects the needle longitudinal axis during its movement.
- the shortening of the ski stroke leads to a reduction of the needle thread loop formed by the needle and thus to a reduction in the risk that adjacent grippers capture the needle thread loop of a needle.
- a reduced compared to previous movement lengths length of a spreader evasion movement support the measures according to claim 1, in order to achieve a secure stitch formation despite a small needle spacing. It has proven to be advantageous in this case if the spreader deflection movement has a length from a range of preferably 4.5 mm to 4.7 mm.
- Each of the grippers may be arranged on a rotary shaft, with which the respective gripper performs a driven alternating pivoting movement.
- the eccentricity generating the alternating pivoting movement can preferably be reduced in embodiments according to the invention in comparison to otherwise usual eccentricities for driving the pivoting movement of the grippers. In the previously customary smallest needle spacing of 4.8 mm, the eccentricity is approximately 4.9 mm. Now, for example, values from a range of 4.0 mm to 4.6 mm, preferably 4.4 mm, may be provided. As a result, shorter pivoting paths of the gripper can be achieved. As a result, the loop taken up by the gripper is not overstretched and thus an intake of the upper thread is improved.

- adjacent gripper tips are 3.2 mm apart.
- the needles 2 are arranged along a straight line which is cut by each of the longitudinal axes of the needles 2 and to which the longitudinal axes are perpendicular. The line also runs perpendicular to the material transport direction. In the illustration of FIG. 1, the line is in the drawing plane of FIG. 1 or parallel to this drawing plane.
- the Nähguttransport exercises is, however, aligned perpendicular to the plane of Fig. 1.
- a needle guard 35 is mounted on the gripper carrier 16.
- This has a plurality of spaced-apart struts 36 which are arranged and aligned so that they represent a guide for the needles 2. If needles 2, for example, due to particularly stiff material, show a tendency to bend and deviate from their desired path, this deviation is limited by the struts 36 and the needles forced to comply at least approximately their desired orientation. In this way it is also ensured that the position of the Oberfadenschiingen 37 each in the range of the respective upper thread loop 37 associated with a gripper 3 and thus each Oberfadenschlinge 37 can be detected by their respective gripper 3.
- a carrier 38 for a plurality of spreader elements may be formed as spreader pins 39.
- the spreader elements may be formed as spreader pins 39.
- the respective bobbin thread 25 of the respective spreader pin 39 associated with a lower thread 25 is detected at a certain time of stitch formation, to deflect this laterally by a Spreizerausweichterrorism predetermined length and direction.
- the spreader escape movement preferably occurs in a direction transverse to the needle movement.
- FIGS. 5 to 10 show the processes in stitch formation in the area of stitch pattern tools. For the discussion of the processes in stitch formation and seam formation, reference will also be made below to FIGS.
- FIG. 5 the three needles 2 and the corresponding thereto three grippers 3 are shown. Each needle 2 carries a needle thread 5 which is passed through the respective Nadelschreib and each of the grippers 3 each carries a lower thread 25 which is passed through the upper leg 3b of each gripper.
- the synchronously moving needle 2 are in the range of their bottom dead center and begin their reversal of direction of movement towards its top dead center.
- the three grippers 3 are on their way to their final position with their gripper tips in front of the needles 2 and are arranged at this time of stitch formation phase before the plane formed by the three needles.
- the grippers 3 are in their rear end position, ie in their direction of movement reversal point, in which they have the greatest distance to the needles. Shortly before reaching this position of each gripper 3 in each case a previously generated thread loop 37 of the upper thread, which was devoured with the associated lower thread 25, due to the movement away from the needles 2, jumped from the grippers 3. This process will be discussed in more detail below for the next following entanglements between the respective upper thread 5 and the associated respective lower thread 25.
- Fadenanzugsfeder 10 is due to a due to the upward movement of the needles 2, also in the field of Fadenanzugsfeder 10 decreasing tension in the upper threads, relieved.
- the spring force of. Fadenanzugsfeder 10 therefore causes a pivoting movement of the bracket 15b of Fadenanzugsfeder in the direction of its first stop 40, in which the Fadenanzugsfeder 10 has the least spring force.
- the grippers 3 On the way from their position in FIG. 6 to their position in FIG. 7, the grippers 3 have already passed the longitudinal axes of the needles 2. As is apparent from Fig. 7, the gripper 3 are already passed with their respective tip by their respective associated only one loop 37. Also, each of the hook tip exiting bobbin thread 25 is thereby performed with a section already by its respective associated loop 37. The thread take-up 11 executes a synchronous with respect to the needles 2 movement and is also in an upward movement. The Fadenanzugsfeder 10 is further relieved due to the decreasing Oberfadenvolutionen and is still on their way to their first stop 40, in which the Fadenanzugsfeder 10 has the lowest spring force
- the gripper 3 have moved on their predetermined curved path, in the embodiment here on a circular arc path, on the gripper tip side end position and are in the illustration of Fig. 8 in this motion reversal position.
- the grippers 3 have taken the loop 37 as far as possible on their upper legs 3b, the loops 37 are each tight, ie with the least possible lateral deflection executed.
- a portion of the upper leg 3b of the respective gripper is arranged with the gripper tips in this position below the Spreizerstatte 39.
- the grippers 3 have by their pivotal movement in each case their lower thread 25 on a particular side of the Spreizerstatte 39 arranged, namely the side in the direction of which the Spreizerite 39 are moving below.
- the lower threads are thus guided in each case behind one of the spreader pins 39.
- the needles 2 are now in the position of their top dead center, in which their needle thread loop is the largest.
- FIG. 8 also includes the representation of the front view of the sewing machine of Fig. 1.
- Fig. 1 are at this time the thread take-11 as well as the needles 2 in their top dead centers.
- the needle and thread take-up movements and the Nähgutvorschubterrorism lead to an increase in the thread tension in the upper threads 5, which is why the Fadenanzugsfeder 10 is loaded with its bracket 15 b through the upper threads 5 maximum.
- the Fadenanzugsfeder 10 is therefore held with the spring force resulting from the tension of the upper threads 5 in its upper, second end position 41 and lies with its bracket 15b with this spring force on the upper threads.
- the Fadenanzugsfeder 10 thus ensures that the Oberfadenschiingen 37 are streamlined and have a small lateral deflection.
- Fig. 9 shows a current position of Spreizerstatte 39, in which the Spreizerstatte 39 already started with their lateral deflection movement and their respective associated associated a bobbin thread.
- the carrier 38 of the spreader elements, together with the spreader pins 39 held and moved by the latter, has been moved backwards with respect to the illustration of FIG. 9 and its plane of drawing.
- the spreader pins have in this case the respectively immediately before each Spreizerstatt 39 arranged lower thread 25 taken along with this movement and thereby deflected in the direction of movement of the corresponding Spreizerstatts 39.
- the needles 2 have already left their position in their top dead center and are again on their way towards their bottom dead center, but are still arranged above the upper leg 3b of the gripper 3.
- the needle 2 have just stabbed into the fabric.
- the grippers 3 now move in a direction opposite to the previously assumed direction of movement towards the second end position of the grippers facing away from the gripper tips.
- the needles 2 pass - due to the deflection of the lower threads 25 and - with respect to the illustration of Fig. 9, each associated with the needle and emerging from this gripper 3 Bobbin thread 25 in front of this lower thread 25.
- the needles 2 then begin to form the following upper thread loop 37a.
- the needle thread loop 37 formed just before is still gripped by the respective gripper 3, as shown in FIG. 9 and also in FIG.
- the needles 2 have moved further in the direction of their bottom dead center and have also passed the grippers 3.
- the upper threads 5 leading thread feeder 11 continues to move synchronously with the needles 2 and also in the direction of its bottom dead center.
- the grippers 3 have covered a further subsection in the direction of their second end position facing away from the gripper tips, which in the illustration of FIG. 10 is located on the left side.
- Each lower thread 25 is further deflected by a spreader pins 39.
- the lower threads 25 come hereby in each case against the associated one needle 2 in Appendix.
- the lower threads 25 jump off from the needles 2 or are released from the needles and then there is an entanglement between each of a lower thread 25 and a loop 37 of one of the upper threads 5 instead.
- the thread take-up spring 10 pivots from its previously assumed upper end position 41 in which it is loaded with its maximum spring force is, towards its left-side end position 40, in which it has the least spring force and thus can apply at least almost no tensile force on the upper threads 5.
- the still located on the respective gripper 3 and formed in the previous Stichchanevorgang Oberfadenschiingen 37 are each kept taut on their respective grippers 3.
- Fig. 12 is to illustrate a possible for the invention and advantageous principal course of the force exerted by the thread tightening means 10, in the case of the embodiment of a spring force.
- the force provided for Fadenzugug force in other ways than by a spring to be provided.
- This force acting on the at least one, preferably on all upper threads at the same time is variable during a stitch formation cycle, that is to say from a position of the needle tips in their top dead center until the subsequent top dead center is reached again.
- the force exerted by the thread tightening means it is preferable in this case for the force exerted by the thread tightening means to occupy several times a maximum value, at least one local maximum value, during the aforementioned stitch formation cycle.
- the force of the thread tightening means may take on a minimum value, at least in each case a local minimum value, several times. It has proven to be advantageous in this case if at least local maximum force values acting on the upper threads are set in the upper and lower dead center of the needles. Minimum force values can be present in particular when the needles penetrate into the sewing material and / or when the needle tip leaves the sewing material in the upward movement. Like the path of the needles, the course of the force of the thread tightening means can also correspond to a cosine curve or a cosine function. As shown in FIG. 12, the respective minimum value may be a non-zero positive value of the force.
- the invention despite a very small needle spacing of adjacent needles 2, which are arranged according to the inline principle of a multi-needle chain stitch sewing machine, allows a secure seaming of seams running parallel to each other at a small distance become. It can be avoided in particular that adjacent, ie belonging to an adjacent seam stitching tools, detect an upper thread and thus prevent seaming. LIST OF REFERENCE NUMBERS
