It has the goal to make the thread entanglement between the front and back thread so that on the one hand Hinterfadenablaufkoerper can be used with a large Bewicklungslaenge, on the other hand, however, a uniform Fadenanzug is achieved. According to the invention, the thread entanglement is carried out by means of the working elements oehrnadel, latch needle, perforated needle, throat plate and tee element, with a Haekelstich arises. The required constancy of the back thread tension is made during the phase of the thread entanglement by means of a control device, wherein the back thread is pulled out against the processing direction from the previously formed stitch. In the remaining part of the working cycle, the back thread is unregulated decreased. The device is constructed so that the working elements of the embroidery machine back side can be withdrawn.

Description

a) Title of the invention

Method and apparatus for making embroidery

b) Field of application of the invention

The invention relates to a method and apparatus for the production of embroidery, this consists of front and back thread and both thread systems are endless. The method and the device enable the production of all assortments of Mas chinens ticker eij _; In addition, the production of articles of multi-needle piercing is possible.

c) Characteristic of the known technical solutions

The production of embroidery is known in such a way that the front and back thread are entwined with each other by means of a lockstitch with the aid of the working elements of the eye needle and the shuttle. For this it is characteristic that Hinter & τ entire Hinterfadenablaufkörper must τ / ground in the shuttle through the front loop of thread. As a result, the thread supply per Hinterfadenablaufkörper is limited _s and it arises particularly'in vielnadligen embroidery machines a high Beaienaufwand for the control of the levels of the boats, the filling of the boats and the replacement of idle boats. Another disadvantage is the high dynamic load of the gear train for Schiffchenanti-iebj high acceleration forces for the movement of the shuttle is necessary »

thus to expand the maximum operating range. In addition, a consistently good drop of goods in all embroidery assortments is to be achieved compared to shuttle embroidery.

e) essence of the invention

The invention has for its object to connect a means of Franselegung embroidered threading thread with the front thread. The connection should be made so that at each cycle of the formed stitch is firmly sucked. Prerequisites for this are the exact, adjustable template of the back thread in front of the stitch-forming work element and each stitch providing such a set back thread, which takes into account not only the stitch size, but auoh the stitch direction-dependent position of the back loop for embroidery needle. Furthermore, the operation of the embroidery point should be possible without difficulty even with the smallest embroidery reports and setup processes can be carried out without problems «Brfindungsgemäß the object is achieved in that a working needle for presenting the front thread an eye needle, as a working element for presenting the back thread a punch needle and as a working element for Meshing of the back thread and passing through the front loop a tongue needle can be used. While all of these working elements to be moved independently of each _s is for knocking the rear yarn loop and bonded therein leading thread loop a rigid tee element for application "The resulting seam corresponds to the known Häkelstichs and is characterized in that the Maschenfuß the rear thread half stitch is tied in the front thread loop and both - Mesh foot of the Hinterfadenhalbmasche and front thread loop - are tied off by the mesh head of the previously formed Hinterfadenmasche.

The working cycle of the embroidery machine working with front and back thread consists of 2 basic parts: the

The regulation is effected in such a manner that the trailing yarn is _s until reaching a preselected 'fadensugkraft pulled out of the stitch auletat formed and that subsequently the level of these Fadensugkraft is kept constant with means known per se *

The unproblematic operation of each embroidery point is achieved by the fact that all moving employees of work are attached linearly to the rulers on the rulers!

the resulting perforated needle movement is generated by means of two spatial curves ~ coupling ~ gear and superimposed on the needle shaft, with the choice of suitable dimensions, a detachment of the needle hole is also possible.

According to an embodiment of the method according to the invention, the influencing of the front thread tufting is also carried out according to the same principle as that of the rear thread tension. This makes it possible to further increase the embroidery speed ^ since the well-known, heavily mass and unbalanced thread guide systems and their drives can be omitted »

It should be noted that the inventive method of influencing the thread tension for front and back thread on the stitch type "crochet stitch" addition can be used in all embroidery methods that use coils as thread drain body, so beispielsv / iron in the front yarn feeding in lockstitch and all Kettenstichvarianten and at the Hinterfadenzuführung with double chain stitch. Finally, in one embodiment of the invention, the thickness of the back thread relative to that of the front thread is increased several times. Since the present in fringe bond back thread is consumed in at least three times compared to the front thread, so creates a much higher degree of embroidery of the back of the fabric over the front. Thus, the side of the textile fabric on which the back thread lies as a fringe seam _{9 can be made} despite a reduction in the number of stitches to the show side of the finished product. This method is particularly suitable for embroidery in the lockstitch character, in which the front and back thread are present in the finished product stretched and the Abbindestelle between the front and back thread coincides with the puncture hole in the fabric.

The front thread 1 is obtained from the front thread spool 2 via the front thread 3 t the XI. Thread guide 4 and the I "thread 5 of the: ¹ Ehrnadel 6 fed _B which is attached to the Öhrnadellineal 7» The feeding of the back thread takes place before, the bobbin 9 via a Hint aft brake 10, a Hinterfaaenlieferwalss® it and a Hinterfadenspanner- 12 for Lochnadel 13 * which is attached to the Lochnadelli neal 14 and submits him in accordance with the practice of the latch needle 15. The latch needle 15 is in turn clamped on the latch needle ruler 16 (Fig. "I) * The working cycle is as follows ι The Öhrnadel β moves from its most distant from the work site position on this zn and penetrates into the stationary fabric i'7 _s between the top stitches

frame roller 18 and the lower embroidery frame roller 19 is present in tension, as well as in the bore of the needle plate 20 a. In this case, the front thread 1 is carried. The latch needle 15 "under the hook is a half-stitch of the back thread 8, remains in its bottom dead center (Fig. 2). In the further course, the eye needle 6 with the front thread 1 reaches a first front dead center and then goes back a bit, whereby a loop of the front thread 1 is formed as a result of the friction between the front thread 1 and the textile sheet 17 or throat plate 20. Now, the latch needle 15 goes up and passes through this loop, which is further increased in the further forward of the eye needle 6 to the second front dead center (Pig.3) · The previously lying under the head of the latch needle 15 half stitch of the back thread 8 slides during the upward movement the latch needle 15 on the _{ tongue of the same on, wherein the tongue undergoes a bending stress. In order to prevent slamming of the tongue as a result of sudden relaxation when the half-stitch of the tongue rests on the back of the latch needle 15, shortly before the top dead center of the latch needle 15, a rigid tongue stop wire 80 attached to the throat plate 20 is stretched, against which the tongue strikes , As a result, the tongue of the latch needle 16 is reliably kept open in the upper part of her path * The needle thread leading the rear needle 8 13 begins with its laying movement by swinging away from the throat plate 20 and a lateral offset relative to the latch needle 15 completes, so that they now a - seen from the embroidery backside - located right next to the latch needle 15 position »Thereafter, the piercing needle 13 again in the direction of the throat plate 20 and sets the back thread 8 under the hook of the downwardly extending latch needle 15. The eye needle 6 begins to go back, the front thread 1 is tightened by the I. Fadenleiter 5 and now encloses the shaft of the latch needle 15 (Fig. 4). As the eye needle 6 further falls, its eye emerges again from the bore of the throat plate 20 and from the textile fabric 17, and thereby pulls the thread outward.

thread 1 with him, which is further streamlined. This and the half-stitch of the back thread 8 automatically close the tongue when the tongue needle 15 continues to fall. "The punch needle 13 latches back into its original position by means of offset and oscillation (FIG. 5)." The latch needle 15 reaches its bottom dead center j Re-formed loop of the '-leaf thread 8 and the incorporated' Front loop 1 sling off 'attached to the needle plate 20''Incident element 21 assists this process and prevents the loop of the back thread 8 and the loop of the front thread 1 from closing be pulled far down "die.Öhrnadel 6 now leaves the textile 'fabric 17 completely, the streamlined front thread 1 the formed stitch through the hole of the throat plate 20 to the fabric 1? (Fig. δ) ₀ Finally, the eye needle 6 reaches its rear dead center. The tensioned between the upper embroidery hoop roller 18 and the lower embroidery hoop roller 19 textile fabric 17 is 'moved according to the pattern, with' front thread 1 and back thread 8 are lowered if necessary (Flg., 7). The stitch thus formed is characterized in that the Maschenfuß _s of the half-loop of the rear thread 8 is bound in the loop of the front yarn 1 and both are bonded by the stitch head of the stitch previously formed of the background thread 8 *

During the phase of the working cycle referred to as "thread entanglement ¹ *, in which the actual intermeshing of the back thread 8 and the integration of the front thread 1 takes place" (FIGS. 2 to 6), the thread suction forces must be adapted to the conditions of stitch formation Foreword 1 this is achieved in a known manner by the interplay of I. thread guide 5 * He thread guide 4 and Vorderfadenlieferwalze 3 ₉ while the back thread 8 is placed under the influence of a control (Fig * 8) .This control causes the back thread supply roller 11 so pull the back thread 8 out of the embroidery stile until the

terfadenspanner 12 assumes a tensioned position in which the attached to him rear actuator 22 interrupts a light beam between the rear transmitter 23 and rear loip catcher 24. As an actuator for the Hinterfadenlieferwalze 11 is a rear stepper motor 25 "The scheme also causes material or pattern typical characteristics of the tensile structure for the back thread 8 are leveled. However, as mentioned above, this rule is not effective over the entire working cycle; it is during the phase of the highest need for back thread 8, the displacement of the textile fabric 17, out of order. In this phase of the working cycle, the rear thread 8 is slowed down over the rear thread brake 10; the rear thread supply roller 11 runs along with empty. The commissioning or decommissioning of the scheme is carried out by means of a rear thread synchronizing disk 26 which is fixed on the machine main shaft 27 and inductive way a connection between a rear thread synchronous transmitter 28 and a rear thread synchronous receiver 29 blocks. Thus, for the rear stepper motor 25 and the rear thread supply roller 11 connected thereto, the startup instruction at each stitch is always issued at the same time of the work cycle; the termination of the movement of the rear stepping motor 25 takes place as soon as the rear actuating element 22 interrupts the light beam between the rear transmitter 23 and the rear receiver 24. This timing is typically different between the timing of the start-up command for the rear stepper motor 25 and the latest possible end-of-travel timing of the rear stepper motor 25 of the engagement between the rear-end synchro-transmitter 28 and the rear-end sync receiver 29 by means of the rear-end synchro-disc 26 The times predefined by the rear thread synchronizing disk 26 remain constant over the entire pattern to be embroidered, but can be readjusted on article change on the embroidery machine.

In a variant of the adaptation of the yarn tension to the conditions of the stitch formation and the front thread is 1

under the influence of a control set (Fig. 10) · 'The structure of the control loop is in principle the same as' for the regulation of the thread suction force of the back thread 8' The division of the on the machine main shaft 2? However, front-mounted synchronizer pulley 44 mounted between front-end synchronizer tail 45 and front-end synchronous receiver 46 is another of the front-side feed shaft 3 drive and thus the deflection of j attached to y-thread tensioner 39 between front-end transmitter 41 and front receiver 42 arranged front actuating element 40 through the front thread 1 is preferably carried out during the return of the eye needle 6 ₉ so in a smaller phase of the working ~ '.'zyklus than in the regulation of Padenäugkraft the back thread 8. During the phase of the thread bladder runs the front thread 1 of the Yorderfadenspule 2 via the front yarn brake 38s the idle front yarn feeding roller 3 and the front yarn tensioner 39 directly, ie without the interposition of yarn guides ₉ for Öhrnadel 6 _O In a further embodiment (Pig. 9) _s ini ^ which the transmission of higher torques during drive of the The back thread delivery roller 11 is possible ± ₉ , the transmitted from the Hinterfaden-Synchronschej.be 26 and «from the rear actuator 22 'signals transmitted to a clutch DC magnet 30 and a brake DC magnet 31 The drive of the Hinterfadenlieferwalae 11 is carried out by a constantly running DC motor 36 via an engine-side shaft 34 »a clutch 33 and a braser-side shaft 35« As long as the rear sprocket 26 between Hinterfaaen sync transmitter 28 and Hinterfaden synchronous receiver 29 engages and the rear actuator 22 is not the straight line between the rear transmitter 23 and rear Sapfänger When the limit yarn tension is reached, the rear actuator 22 triggers the DC coupling magnet 30 and the DC brake magnet 31.

The clutch DC solenoid 30 causes via the clutch lever 32, a decoupling of the clutch 33 and thus a separation of the connection between motorseitigsr shaft 34 and brake-side shaft 35 · The DC brake magnet 31 operates the brake 37, so that the rear thread supply roller 11 comes to a standstill. During the phase of the embroidery frame movement, the idling of the Hinterf adenlief is rolled 11, characterized in that the predetermined time of the Hinterfaden synchronous disk 26, the DC brake magnet 31 drops, the brake 37 is released and thus idling the Hinterfadenlieferwalze 11 is possible. This embodiment is of course also suitable for driving the front thread supply roller 3, if the front thread 1 - as already described - is placed under the influence of a control.

To operate the embroidery point and in particular for tensioning and unclamping the textile fabric 17, it is necessary to move the workpieces located in front of and behind the textile fabric 17 away from each other when the embroidery machine is at a standstill. For this purpose, the throat plate 20 with teeing-off element 21 and tongue stop wire 80, the tongue-needle ruler 16 and the piercing needle shaft 55 are moved horizontally away from the textile fabric 17. For the needle plate 20 and the reed needle 16 this is done in a conventional manner according to the same principle as when moving the Schiffchen- and the driver ruler in shuttle embroidery machines. For the removal of the pin needle shaft 47, a cam coupling gear is used, which also allows the merging of elementary movements "vibration" and "offset" to the resulting movement of the needle needle shaft 47 and thus the Lochnadellinseal 14 and the needle hole 13 (Fig. 11 to Fig 13).

For the generation of the elementary motion "vibration" a cam for vibration 48 is fixed on the machine main shaft 27, whose movement on the gear elements roller 49, I. angle lever 50, coupling 51 and lever 52 on a shaft

53 is attached to the other end of the shaft 53. A rocker arm 54 which transmits the movement to a tension rod 55 with pendulum plain bearings mounted on both sides, the angle lever 56 then generates the oscillation movement of the needle shaft 47 a cam plate for offset 57, also located on the machine main shaft 2, which: moves via a gear train roller 58, I, angle lever 59, coupling 60 and lever 61 a hollow shaft 62 which surrounds the shaft 53. The rocker arm 63 transmits the movement a pull rod 64, a II. crank lever 65 and a link lever 66 with a ball head on the guide needle shaft 47 · the whole gear train is so dimensioned that it can be fitted to existing large embroidery machines "enables the design on the other hand, in particular the relatively large length of the tie rods 55 and 64 and their linkage to pendulum plain bearings, moving off the hole needle shaft 47 by means of a known, not shown here, horizontal column guide ·

A further embodiment for driving the needle needle shaft 47 is to generate the required movements in a gear box 67 arranged close to the needle needle shaft 47 (FIGS. 14 to 16) _e Since the forces acting on the needle roller 47 are relatively small, then the gear box 67 are kept small and light, whereby it can be moved horizontally together with the needle shaft 47 if necessary. This eliminates additional transmission elements * The drive shaft of the gearbox 67 runs synchronously to the machine main shaft 27, the synchronization is effected by known transmission elements. A trunnion cam 69 and a face cam disk 70 are rigidly connected to the drive shaft 68. The drum cam 69 is engaged by a roller 71 which is connected to a sliding block 72 which is guided in a straight guide 73. By means of a coupling 74, the oscillatory motion is transmitted to the output oscillations 75 and then, by means of splined profile on the pin needle shaft 47 *

91 f

The Stirnnutkurvenscheibe TO is scanned by a roller 77 which is connected to a sliding block 78, which in turn runs in a linear guide 79. The roller 77 and sliding block 78 are rigidly connected to the offset lever 76, whereby the elementary movement "offset" is generated. As in the previously described embodiment, the geometrical addition of both elementary movements takes place directly on the needle-point shaft 47. The use of the splined profile makes it possible to superpose the elementary movements "oscillation" and "offset".

Finally, in a design according to the invention as a back thread 8, a thread material is used, which is much stronger than the front thread 1, for example, 30 tex χ 2 PE-F. The front thread 1 consists of 10 tex PE-S. The seam pattern of this embroidery is characterized in that the embroidery back side becomes the show side, since the back thread 8 optically dominates (FIG. 17). The optical emergence of the front thread 1 is additionally prevented in this embodiment in that it is used in the same color as the back thread 8 or transparent.
