Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for producing embroidery that is made of decorative threads and loop threads and in which both thread structures are endless. This method and apparatus allows the production of all types of machine embroidery, and also allows the fabrication of multi-needle quilted articles.

German Patent No. 27922'i describes a method and an associated device, in which a shading yarn is tied by a foam-free loop yarn, the loop yarn being tied through a loop of the shading yarn and itself Pile loop? The loop-forming KL used is tied. This type of thread loop formation has been established under the concept of 6 Henkel Embroidery 77 Methods 1. Large surface length with this method? Although it is possible to use a loop thread supply with a loop thread supply, this method suffers from the drawbacks of extremely expensive construction and furthermore difficult to access embroidery positions and inaccurate loop thread supply. In particular, the latter point is decisive with regard to the quality of the embroidery, and has already been described in German patent no. It was suggested that it be dressed up. However, since these thread guides operate with a constant motion independent of the thread tension situation at the end of each loop, it is therefore not possible to guarantee uniform thread approximation and the resulting perfect appearance of the article. The strength of the loop yarn is considerably lower than that of the loop yarn. Sara VC German Democratic Republic Patent No. 14
No. 2967 proposes the use of a control device to construct a yarn guide in a textile machine by means of a VC, so that the yarn reaches the processing position 1 with a constant tensile stress. This device as described allows for the opening movement of the entire working cycle, respectively, but also does not allow excessive thread withdrawal from the working position.

The object of the present invention is to use the Henkel embroidery method VC45! The overall goal is to achieve improved product quality results. Furthermore, it must be possible to operate the work area without obstruction even when working with the smallest embroidery structures.

The object of the invention is to connect the embroidery loop thread formed by using the decorative thread and the pile loop in such a way that the formed loop is tightly tightened during any working cycle.

According to the present invention, this problem is solved in the following manner. That is, the thread thread is threaded through the entire fabric to be embroidered and forms a loop on the embroidery side of the fabric, after which the loop thread is threaded through this loop thread and forms a pile. VC to be formed. Preferably, at this stage of the working cycle, the loop yarn tension force is at a preselected maximum value. Controlled until guaranteed.

A large demand for yarn occurs at that stage, preferably in the working cycle, following the movement of the woven fabric? The loop thread is loosened uncontrolled so as to meet. The tension control of the loop yarn is carried out in such a way that the loop yarn is pulled out from the last formed loop until the preselected maximum tension force of the loop yarn is achieved. The time required will therefore vary depending on the existing loop yarn surplus. Its maximum duration is determined to be equal to the maximum possible duration of the control phase and to be synchronized with the position of the machine spindle.

The device according to the present invention includes a pointed thread guiding needle as a working member for supplying the ripple thread, a reed as a working member for supplying the loop thread, and a working member for forming a loop of the loop thread and passing the loop of the ripple thread by force. Contains a bellows needle. While all these working members are moved independently with respect to each other, a rigid evacuation member is used to eject all the thread loops and the swatch thread loops knotted therein, and this member itself is attached to the fabric to be embroidered. It is fixed to a needle plate that supports the fabric and includes a hole for the passage of a pointed thread guide needle. The loop thread is wound around a bobbin. Between the bobbin and the reed, there is a loop yarn supply roll connected to a rear step motor and having a loop yarn brake disposed upstream and a loop yarn tensioning device disposed downstream, and a rear operating member is fixed by the tensioning device. . Parallel to the loop yarn supply roll and in the trajectory of the rear operating member there is a connecting line between the rear transmitter and the rear receiver. Furthermore, a loop thread synchronization disc is fixed on the machine main shaft, which disc cooperates with the loop thread synchronization transmitter and the loop thread synchronization receiver.

At the beginning of the thread looping stage, the pointed thread guide needle pierces the fabric to be embroidered as well as the entire hole in the needle plate, and when the thread guide needle returns, the decorative thread forms a loop.
This loop needle, which wraps around a half-loop of loop yarn at its head, passes through it during its upward movement. The latch needle now reaches a position where the looped thread, guided by the deflection and oscillation, is placed under the head of the latch needle.

The half-loop of the loop yarn, which was previously under the head of the latch needle, then slides onto the shank of the latch needle.

After that, feed all of the thread around the bellows needle to completely loop it. During the downward movement of the bellows needle, the strong escape member fully supports the escape of the loop of loop thread and the curly thread loop tied therein, and the pre-inserted loop thread is formed into a half loop. . Meanwhile, the tip-guiding needle moves again in the direction of its rear dead center and the pile of looped thread is tied to it? Motsukazaari is drawn to the light sound textile fabric.

Preferably, the initiation of the movement of the rear stepper motor is controlled by a signal emitted by a loop thread synchronization transmitter/loop thread synchronization disk/loop thread synchronization receiver pair which is activated during the described stage of thread loop formation. The stepper motor moves the loop yarn supply roll so that the loop yarn is pulled out from the working position. The loop thread tensioning device, L and the rear operating member are then moved into the connection line between the rear transmitter and the rear receiver. When the connection line is disconnected, the operation of the rear step motor is immediately stopped.

A step of moving the textile fabric follows to a step of yarn loop formation. At this stage, the tip of the needle is at its lower dead center. The latch needle is at its lower dead center and the reed is displaced laterally with respect to the latch needle trajectory. The loop thread is not controlled and the loop thread brake is constant and l1ll! Only a controllable braking force can be applied to the direction of the hole in the throat plate and loosened. In this case, the idling loop yarn supply roll is rotated by the loop yarn.

The invention will now be fully described in detail with reference to embodiments of the invention illustrated in the accompanying drawings.

The shading thread 1 is passed from the shading thread bobbin 2 to the shading thread supply port ~
6, the first thread guide 5 and the first thread guide 5 to a pointed thread guide needle 6, which thread guide needle is fixed with its guide 7. The loop yarn 8 is supplied from the loop yarn bobbin 9 via the loop yarn brake 10, the loop yarn supply roll 11, and the loop yarn tension device 121r to the reel 15, which is fixed by its guide 14. In addition, the Loog yarn is sent to the bellow needle 15 correctly in terms of processing. Bella needle 15
itself is tightened by the latch needle guide 16 (first
figure).

Its working cycle is as follows. That is, the pointed thread guide needle 6 is moved from the position furthest from the working position to the working position, is tensioned between the upper embroidery frame roll 18 and the lower embroidery frame roll 9, moves forward, and then stops. It penetrates into the woven fabric 17 and the holes in the throat plate 20. At that time, the ornamental thread 1 is carried along. 71 The needle 15 has a half-loop of the loop yarn 8 below the needle 15, and its lower dead center ρ) remains unchanged (Fig. 2).

After further elapse, the pointed thread guide needle 6 moves to the first thread along with the decorative thread 1.
It reaches the front dead center and then slightly returns again, and at the same time, a loop of the sewing thread 1 is formed due to the friction between the sewing thread 1 and the textile fabric 17 and the throat plate 20. Now the bellows needle 15 advances towards the top and passes through this loop,
When this loop is further advanced through the pointed thread guide needle 6 to the second front dead center, it becomes further enlarged (see Fig. 5). Bella needle 1
During the upward movement of step 5, it slides onto the tongue of the bellows needle, causing the tongue to undergo all the bending stress.

A rigid tongue fixed to the needle plate 20 just in front of the front dead center of the tongue needle 15 in order to prevent shocks due to sudden expansion during the half-loop sliding from the tongue piece to the back of the tongue needle 15. A single contact wire 80 is tensioned and the tongue contacts this wire. The upper range of the stroke of this T-shaped tongue piece is reliably opened to the latch needle 15. The basket that guides the loop thread 8 has swung away from the throat plate 20 and has completely shifted laterally with respect to the needle 15, so that it is now on the right side near the needle 15 when looking from the back side of the embroidery. Trying to reach a certain position,
The feeding movement starts completely. Then o-gh, needle plate 2 again
8 loop threads are fed below the hook of the latch needle 15 which oscillates in the direction 0 and moves downward in the process. The pointed thread guide needle 6 begins to return, and the first thread guide 5? A force is applied to the stem fC*D of the bellows needle 15 (FIG. 4). When the pointed thread guide needle 6 returns further, the thread guide part of this needle is again connected to the needle plate 20 and the fabric. When it comes out of the fabric 17, it pulls the ornament thread 1 by itself, making the ornament thread feel even more tense.The half loop of the ornament thread 1 and the loop thread 8 is
When the bellows needle 15 returns further, it automatically closes its tongue. The reed 15 returns to its starting position by deflection and oscillation VcL (FIG. 5). The bellows needle 15 reaches its lower dead center, and the newly constructed loop of the looped thread 8 and the loop of the shading thread 1 tied with the loop are escaped. The escape member 21, which is fixed on the throat plate 20, provides full support during this process and ensures that the loops of the sling thread 8 and the loops of the sling thread 1 are not pulled too far toward the bottom. Now, the pointed thread guide needle 6 leaves the woven fabric 17 under full pressure,
The taut decorative thread 1 draws the formed loop tube to the textile fabric 17 through the hole in the needle plate 20 (FIG. 6).

Eventually the tip-guiding needle 6 reaches its lower dead center.

Upper embroidery frame roll 18 and lower embroidery frame roll 19
The woven fabric 17 tensioned between the woven fabric 17 and the woven fabric 17 is displaced according to the pattern, and the swatch thread 1 and the loop thread 8 are loosened as necessary (FIG. 7). The loop thus formed is formed in such a way that the loop shank of the half-loop of the loop thread 8 is tied with the loop of the decorative thread 1 and both threads are tied by the loop head of the preformed loop of the loop thread 8. Features.

〃・The original loop formation of the thread 8 and the knotting of the thread 1 are carried out (see Figures 2 to 6). In the case of the decorative yarn 1, this is achieved by the cooperation of the first yarn guide 5, the first decorative yarn guide 4 and the decorative yarn supply roll 3, and the loop yarn 8 is controlled by the controller. (Fig. 8) This control part m shows that the loop thread tensioning device 12 occupies the tensioning position, in which the operating member 22 fixed by the tensioning device engages the rear transmitter 23. While the light beam is interrupted between the rear receiver 24 and the loop yarn supply roll 1, the embroidery position force is applied to the loop yarn supply roll 1 to fully pull out the loop yarn 8.The rear stump motor 25 serves as the final control member for the loop yarn supply roll 11. This control device acts in such a way that the characteristics representative of the material or operation of the tension force configuration on the loop thread 8 are leveled.However, as mentioned above, this control device is is not effective throughout and does not operate the movement of the textile fabric 17 during the phase in which the loop yarn 8 is most needed.At this stage of the work cycle the loop yarn 8 is braked and loosened via the loop yarn brake 10. and the loop yarn supply roll 11 idles together.The operation ``17t'' of this control device is inoperatively carried out by the loop yarn periodic disk 26, which is fixed by the device main shaft 27 and rotates 9'1. . prevents the connection between the loop yarn synchronization transmitter 28 and the loop yarn synchronization receiver 29 in a guided manner.Therefore, a starting command is issued to the rear stepper motor 25 and the loop yarn supply roll 11 connected to this motor. is always given for the same point in the working cycle during any loop, and as soon as the rear operating member 22 interrupts the light beam meeting between the rear transmitter 25 and the rear receiver 24, the remote step motor 25 is The movement is terminated.At this point, the rear step motor 25
The loop thread synchronization transmitter 28 and the loop thread synchronization with the help of the loop thread synchronization disk 26 are different on behalf of the loop between the time of the start command for and as late as possible for the end of the movement of the rear stepper motor 25. Suitable for blocking connections with receivers.

The nine time points pregiven by the loop thread periodic disk 26 remain constant throughout the embroidered pattern, but when the embroidery device changes the entire article, a new point: lI
I can adjust it.

In a variant of the adaptation of the thread tension force to the circumstances of loop formation, the loose thread 1 is also placed under the influence of the control device (Fig. 10). However, it is fixed to the main shaft 27 of the device and has a thread synchronization transmitter 45 and a thread synchronization receiver 4.
The scale of the decorative thread synchronization disk 44 provided between the threads and the threads 6 is another scale. The front stepper motor 45 is driven by the front step motor 45 which is connected to the sash thread supply roll 3' and is fixed by the sash thread tension device 39 and provided between the front transmitter 41 and the front receiver 42. The deflection of the actuating member 40 is preferably effected by the hexagonal thread 1 during the return of the pointed thread-guiding needle 6, during the control of the tensioning force of the loop thread 8, and also during short stages of the working cycle. During the thread loosening stage, the shading thread 1 is directly guided from the shading thread bobbin 2 via the shading thread brake 38, the idling shading thread supply roll 5 and the shading thread tensioning device 59f, and without the intervention of a thread guiding system. Proceed to thread needle 6.

In another implementation (FIG. 9), in which it is possible to transmit relatively large torques during the drive of the loop yarn supply roll 11, the signals sent to the loop yarn synchronization disk 26 or to the rear operating member 22 are , are transmitted to the clutch DC electromagnet 30 and the brake DC electromagnet 51. The loop yarn supply roll 11 is driven by a constantly rotating DC motor 56VC via a motor shaft 34, a clutch 53, and a brake shaft 55. The loop thread synchronization disk 26 is the loop thread synchronization transmitter 2
8 and the loop thread synchronization receiver 29 and the rear operating member 22 does not interrupt the connection between the sonic wave transmitter 25 and the rear receiver 24, the motional flux is closed. 9. The loop yarn supply roll 11 pulls out the loop yarn 8 from the loop formation.

When the tension limit of the thread is reached, the VC releases the clutch DC electromagnet 5o and the brake DC electromagnet 51 to the rear operating member 22. Clutch DC electromagnet 30μ, clutch lever 5
Disengagement of the clutch 53 through two sessions, and therefore separation of the coupling between the motor side shaft 54 and the brake side shaft 35? Let's do it. Since the brake DC electromagnet 31 operates the brake 67, the loop yarn supply roll 11 stops.

During the phase of the embroidery hoop movement, the idle rotation of the loop thread supply roll 11 is caused by the braking DC electromagnet 31 dropping with respect to a predetermined point in time by the loop thread synchronization disc 26, and the braking motor 57
is loosened and thus the loop yarn supply roll 11 is allowed to idle. It goes without saying that this application is also suitable for driving the ornament thread supply roll 5 if the ornament thread 1 is, as already mentioned, placed under the influence of a control device.

The embroidery area? In order to operate and, in particular, to tension and unroll the textile fabric 17, all working elements on the front and rear sides of the textile fabric 17 must be separated from each other when the embroidery device is at rest. Therefore, the escape member 21, the tongue contact wire aol needle plate 20, the latch needle guide 16 and the reed shaft 55 are displaced from the textile fabric 17 in the horizontal direction. This is needle plate 20
For the needle guide 16, a cam is used to displace the shaft 47. A connecting rod mechanism is used, and this mechanism includes a reed shaft 47,
Therefore, one "oscillation" and "deviation" which are the basic movements for the combined feed motion of the reed guide 14 and the reed 13
It is also possible to combine (Figs. 11 to 13).

In order to generate the basic motion "swinging", the swinging cam disc 48 is fixed on the device ball shaft 27, and the movement of the disc is controlled by the transmission member roll 49, the first bell crank 50, the connecting rod 51 and the lever 52. On the other side of the shaft 55, a crank oscillating part 54 is fixedly mounted, and this oscillating part is transmitted to the drawbar 55 through inclined sliding bearings mounted on both sides. Then, the first bell crank 56 generates the entire oscillating motion of the recessed shaft 47.Basic: +!!movement °E movement'' is caused by the displacement cam that also falls on the device ball shaft 27. It is generated by a disk 57, and this disk also moves on the hollow shaft 62 through the roll 58, which is one row of transmission devices, the first bell crank 59, the connecting rod 60, and the lever 61, and moves the hollow shaft 62 through the shaft 55? surround. Crank swinging section 65
Then, the motion is transmitted to the reed shaft 47 via the tow bar 64 and the first bell crank 50 . The entire Lt row of conductors is dimensioned to be able to be additionally configured with existing large embroidery equipment, and can be expanded by other forces, especially the relatively large lengths of the 1155 and 64 traction units and the Vc#4 It is possible to pivot the traction shaft using a diagonal sliding bearing, and to shift the awn shaft 47 by means of a horizontal column guide section, which is not shown in this specification.

A further implementation of driving the reversing shaft 47 consists in generating all the required movement in a transmission box 67 which is arranged closely next to the reversing shaft 47 (sections 14 to 16). forehead shaft 4
7. Since the force is relatively small, the transmission box 67 (2
It is small and can therefore be held down lightly, so that the box together with the shaft 47 can be displaced in the horizontal force direction as required. Additional transmission elements are thus eliminated. The drive shaft of the transmission box 67 rotates synchronously with the device main shaft 27,
The synchronizing action is carried out by a transmission element known per se. The cylindrical cam 69 and the end groove cam 70 are connected to the drive shaft 6.
8. A roller 71 is engaged with the cylindrical cam 69, and this roller is connected to a sliding block 72, which is guided by a linear guide 75. Connecting rod 74
The oscillating movement is then transmitted to the driven oscillating part 75 and from there to the reed shaft 47 by means of the tin line contour.

The end cam 70 is mounted on a roller 77 to form a scanning field, and the roller is connected to a sliding block 78, which itself runs on a linear guide 79. The roller 77 and the sliding block 78 are rigidly connected to the deflection lever 76 so that an elementary movement of 1 shift # is generated. explained earlier fc
Also during implementation, the addition of the forms of both basic movements is performed directly on the recessed shaft 47. The use of tin line contours allows for an overlapping meeting of their basic motions ``oscillation'' and ``shift''.

As a result, in the implementation of the present invention, yarn materials that are considerably thicker than 1Vc yarn, such as 50 texX2PK-.

F is used as loop thread 8. Decorative thread 1 is 10
tex PI-8. The binding structure of this embroidery is characterized by the fact that the back side of the embroidery is on the front side. This is because the decorative thread 8 is superior in appearance (FIG. 17).

In this embodiment, the apparent protrusion of the decorative thread 1 is the loop thread 8.
This is further inhibited by using the same color or transparent material.
