Description

Embroidery machines, especially shuttle embroidery machines

The object of the present invention is an embroidery machine, especially a shuttle embroidery machine, according to the first general concept of the scope of patent application.

In EP 0 768 418, an upper thread cutting and clamping device for cutting upper threads is described. The upper threads are also referred to as needle threads. Among them, cloth pressing fingers or claws have been designed on the cloth pressing plate. Cutter ruler that moves in the vertical direction. On this cutting ruler, the thread catcher is provided with an inclined end for catching the upper thread guided from the needle to the cloth. In addition, a hook-shaped knife is designed on the cutting ruler, and a cutting edge or cutter formed on the cloth pressing plate, if the knife is guided downward with respect to the cloth pressing plate, the line caught by the catch hook will be cut. With this known device, all the threads extending between the cloth and the embroidery needle can be cut at the same time. In addition, the end of the thread introduced by the needle is clamped on a device after cutting, so in the further embroidery process There is no need to rethread from the eye of the needle at the corresponding embroidery position. With this device, the wire can be accurately cut and temporarily securely clamped. However, the disadvantage of this device is that all threads are always cut simultaneously, rather than just the threads currently in the embroidery process. Another disadvantage of this known device is that all the thread cutting and clamping devices on each stitch during the embroidery swing with the cloth presser foot, for example 600 to 700 times per minute. This means that a volume of 600 to 700 times per minute must be continuously accelerated and delayed. This may cause vibration and noise, and increase the wear of the embroidery machine. In addition, this device has the disadvantage that the upper thread is cut away from the embroidery orifice and The embroidery material on it is relatively far away, which leads to a large consumption of threads. In addition, the thread ends on the embroidery fabric must be removed later. In addition, it has proven to have the disadvantage that, if not needed, the clamped thread can be released again by the joint action of a cutter or a clamping jaw.

One task of the present invention is to provide a cutting and clamping device for upper thread or needle thread on a large-scale embroidery machine, which can cut and clamp the embroidery thread only at a selected embroidery position.

Another task is to provide an embroidery thread cutting and clamping device, whereby the embroidery thread to be cut can be cut off immediately next to the embroidery orifice plate.

Another task of the present invention is to provide a simple driving device for a selected active embroidery thread cutting and clamping device.

Another task of the invention is to design a separately replaceable embroidery thread cutting and clamping device.

This type of task is solved by an embroidery machine with an upper thread cutting and clamping device provided by the first feature of the scope of the patent application.

Advantageous embodiments of such an embroidery machine are explained in the scope of the dependent patent application.

By using an embroidery thread cutting and clamping element which is placed on a stand beam that can be swiveled independently of the cloth press plate and can be activated or deactivated separately, the needle thread can be cut and reliably clamped in the temporarily embroidered position . If necessary for the cutting process, the gantry beam and the embroidery thread cutting and clamping member fixed thereto swing only in the direction of the embroidery orifice plate, and remain in a stationary position during embroidery. The cutter is also operated only at each position where embroidery is required. This allows the cutter to be worn to a minimum. Defective or worn cutters require no tools and can be removed and replaced from the bench beam by replacing individual embroidery thread cutting and clamping elements. As a result, downtime of the embroidery machine can be greatly reduced Time, compared with other known devices, the replacement cost of the device is reduced to a minimum. By arranging separately operable embroidery thread cutting and clamping members, the thread ends to be clamped can be clamped by a sufficiently long thread segment, thereby eliminating the laborious threading process in the future. Because the new embroidery thread can be easily inserted into the clamping device from above, and then the excess thread ends are removed by one-time operation of the embroidery thread cutting and clamping device, thereby forming the same condition as the previously cut embroidery thread, and the product is replaced. Or need to use other embroidery threads or other color embroidery threads during the threading process, which significantly simplifies the modification of the machine.

In FIGS. 1 and 2, in order to understand the present invention, the necessary elements in a large shuttle embroidery machine are described. In these figures, the embroidery thread cutting and clamping device for cutting and clamping the needle or upper thread between the shuttle rail Stöckli 3 and the sewing machine 5 can be clearly seen-hereinafter referred to as embroidery thread cutting and Clamping device 1. The shuttle track Stöckli 3 can be moved around an axis not shown here to facilitate access to the embroidery base plate 7 between the embroidery orifice plate 9 and the needle 15. An embroidery orifice plate 9 is provided between the embroidery bottom plate 7 and the shuttle rail Stöckli 3. In order to see more clearly, the shuttle in the shuttle track Stöckli 3 is omitted.

On the right side of the embroidery bottom plate 7, the needle 13 can be seen above the needle 13 to be held by the needle holder 15. Below the needle 13 is a drill 17 which is held by a drill holder 19. The needle 13 is driven by a needle link 21; the needle drill 17 is driven by a drill link 23. The crank end 25 of the needle link 21 or the end 27 of the drill link 23 is held by a torsion spring that is compressed and swingable and is mounted on a cylindrical shaft 29 or 31. In addition, the figure shows a slider 33 which is driven by a linear driving device 34 and is mainly movable in the axial direction. A first wedge 35 and a second wedge 37 have been mounted on the slider 33, and their inclined sloped surfaces are in contact with the unused ends of the crank ends 25 and 27. The front end 41 provided on the left end of the slider 33 is bent or T-shaped and contacts a curved lever or a rocker 43. It is an embroidery thread cutting and clamping device 1 or an embroidery thread cutting and clamping The component 55 is a component and can swing about the axis B (FIG. 4) thereon. The device 1 is arranged on a shaft 42 and can swing around a shaft C. In order to see more clearly, the swing driving device in the direction of the arrow P is not shown or is mostly shielded. In addition, the device 1 also includes a shelf plate 45 which corresponds to the pitch of the needle 13 of the embroidery machine and enters the keyhole-shaped groove 47 at regular intervals.

In Figs. 3a and 3b, a drive beam 49 is provided in a metal beam designed to span multiple embroidery positions before the stand plate 45 as a whole or longitudinally divided into several parts along the embroidery machine. The driving beam 49 can be moved up and down in the vertical direction (arrow F) by the push rod 51, and is guided into the stage plate 45 by the guide rod in the slot 46. The push rod 51 is driven by a drive device 53 which is not described in detail. In FIGS. 3a and 3b, for better clarity, the embroidery thread cutting and clamping member 55 provided on the stand plate 45 is omitted. These will be described later with reference to FIG. 4.

FIG. 4 is a perspective view of the embroidery thread cutting and clamping member 55, in which the same structure is described in detail. The longitudinally extending slide plate 57 carries other necessary elements for cutting and clamping, such as a clamping plate 59, a cutting blade 61 and a grapple 63. Grapple 63 and cutting blade 61 is mounted between the splint 59 and the slider 57 and is movable longitudinally in a guide housing 65. The guide housing 65 is fixed to the slide plate 57 by, for example, two screw connection devices 67. Preferably, the clamping plate 59 is clamped in a slot 69 in the guide housing 65 and is fastened through the screw connection device 67.

Furthermore, below the guide housing 65, a carriage 71 is guided longitudinally in the slide plate 57 in a groove-shaped groove 73. The carriage 71 is fixed by a sleeve 75 in a T-shaped longitudinal section, a flange surface externally placed in the groove groove 73, and fastened to the carriage 71 by a bolt 77 and a nut 79. A coil spring 85 is clamped between the upper end 81 of the carriage 71 and the lower end 83 of the guide housing 65. The threaded end of the coil spring is held in a hole in the guide housing 65 and in the carriage 71. By the coil spring 85, the carriage 71 is pressed down by the spring force until the neck of the T-shaped sleeve 75 reaches the lower end of the groove-shaped groove 73 in the end position. The carriage 71 is also provided with a rocker 87 placed on a bolt 89 penetrating the carriage 71, and the rocker can be rotated. The rocker 87 includes two legs arranged in parallel with each other and penetrated by a bolt 89 in the middle. A nose-shaped end region 93 is preferably formed on the upper ends of the two legs 91. The lower ends of the legs 91 are connected to each other by a web 95 to form a flat lower edge 111.

By means of a helical torsion spring 97 surrounding the bolt 89, the rocker 87 and the web 95 rotate in a clockwise direction, so the web 95 is pressed against the cantilever 99. The cantilever 99 is either a part of the carriage 71 or is fixed on the carriage and protrudes outward, and extends downward parallel to the slide plate 57. The lower end of the cantilever 99 is bent at 90 °. The cantilever 99 is protruded in the direction of the slider 57 by the curved end portion 101. In the lower region or at its lower end, a keyhole-shaped groove 103 is provided in the slide plate 57.

The upper narrow surface of the slide plate 57 on the right side in FIG. 4 is provided with a sharp cutting blade 105. The upper end of the cutting blade 61 extending mainly at a right angle and the lower end of the grapple 63 formed mainly at a right angle are kept clamped between the end of the slide plate 57 and the clamp plate 59 (also compare FIG. And 7c).

In Figs. 5a to 5c, the embroidery thread cutting and clamping member 55 is described in a side view. The embroidery thread cutting and clamping member 55 is fixed on the stand plate 45. The fixing on the pedestal plate 45 is achieved by passing the T-shaped sleeve 75 through the keyhole-shaped groove 47 (see FIGS. 3a to 3b), and the second keyhole shape locked on the pedestal plate 45 The clamping screw 107 in the groove 103 realizes a mating connection. In Fig. 5b, the spacing of the embroidery thread cutting and clamping member 55 from the stand plate (45) is described. In Figs. 6a to 6c, the engagement is performed by the upper embroidery thread cutting and the displacement of the clamp 55. The movable mounting of the two corresponding elements on the stage plate 45 is clearly shown by the clamping screws 107. In addition, it can also be seen in FIG. 6c that the cantilever 99 or the curved end 101 will engage an opening 109 in the driving beam 49. At the same time, the space between the hook-shaped end 101 of the cantilever 99 and the lower edge 111 of the carriage 71 is filled by the upper area of the driving beam 49 on the upper part of the opening 109. The embroidery thread cutting and clamping member 55 or its carriage 71 is therefore connected to the drive beam 49 substantially without a gap. As a result, it can be moved in the vertical direction together with the driving beam 49 of the carriage 71 with respect to the urging force of the coil spring 85.

The driving beam 49 is connected to the push rod 51 (see also FIG. 3). The push rod 51 is connected to a driving device that can swing about the axis A in the form of a swing rod. The driving device or the swing lever can be swung by means not shown here, and thus the push rod 51 can be mainly moved vertically upward or downward. The driving beam 49 can be moved in parallel in the vertical direction by the push rod 51. With this, once the curved end 101 on the cantilever 99 engages in the opening 109, and thus the movement of the driving beam 49 is transmitted to the carriage 71, the embroidery thread that has been engaged on the driving lever 49 is cut and clamped The piece 55 also moves vertically. With the help of the carriage 71 to which the cantilever 99 is fixed, the embroidery thread cutting and clamping member 55 that has been engaged on the first path of the vertical movement continues to move up a first path as shown in FIG. 4. Therefore, in the first path, all the activated embroidery thread cutting and clamping members 55 face upward The embroidery plate (see Figure 2) moves for a period. If the driving beam 49 continues to move, the cutting blade 61 and the grapple 63 will also be moved by the same amount. However, the slide 57 and the splint 59 remain unchanged (FIGS. 7a to 7c). At the end of the first path, only the clamping screw 107 and the upper end of the groove in the device enter the slide 45. When the embroidery thread cutting and clamping member 55 is further moved, only the carriage 71, the cutting blade 61, and the grapple 63 are moved. Therefore, only one end of the cutting blade 61 or the grabbing hook 63, which mainly extends in a vertical form, protrudes outward through the sharp edge of the slide plate 57 and the upper edge of the clamp plate 59.

Other functionalities of the embroidery thread cutting and clamping member 55 are described in FIGS. 8a to 8c. The linear unit swings counterclockwise about the axis of the bolt 89 by a force and a linear actuator 34 on the end 93 of the upper leg 91 of the rocker 87. By swinging the rocker 87, the lower edge 111 of the lower leg of the rocker 87 moves out of the effective range of the driving beam 49. As a result, when the driving beam 49 starts, the lower edge 111 no longer enters the device with the driving beam 49, and therefore the rocker 87 no longer moves upward and stays or remains in the lower position. As a result, the rocker 87 and the carriage 71 no longer move upward, and the cutting blade 61 and the grapple 63 also stay in the position between the slide plate 57 and the plywood 59, or the entire component remains passive, a embroidery that may be clamped The wire remains clamped.

The working principle of the embroidery thread cutting and clamping device 1 will be described below with reference to the drawings. According to FIG. 1, starting from the positioning of the device 1, the upper end of the sliding plate 57 is far from the embroidery orifice plate 9 relative to a cloth pressing device or a cloth pressing claw 113. Each single element of the embroidery thread cutting and clamping member 55 is positioned with reference to Figs. 6a to 6c. In this position of the device, the embroidery machine can be stopped or embroidered, that is, an embroidery pattern can be produced, and the embroidery fabric pressing claw 113, the embroidery needle 13, etc. can be moved accordingly.

When changing the embroidery thread, this means the stop of one embroidery position and the adjustment of the other embroidery position, the machine stops working (the needle is taken out of the fabric, the cloth press device is opened, etc.). The stage plate 45 swings counterclockwise around the axis C. The upper end of the slide plate 57 moves near the embroidery orifice plate 9, In order to make the needle thread from the embroidery material on the embroidery orifice plate 9 to the eye of the needle thread as close as possible to the embroidery material. When the swinging end of the gantry plate 45 and the embroidery thread cutting and clamping member 55 make the first upward movement, the grappling hook 63 and the cutting blade 61 are between the sliding plate 57 and the clamping plate 59, as shown in FIGS. 6a to 6c. Close to the embroidery bottom plate 7. Subsequently, the cutting process involved is carried out, wherein the drive beam 49 first continues to move upwards in the direction of the arrow f. By moving the driving beam 49 upward, the carriage 71 is pushed upward with respect to the stage plate 45, and at the same time, the grapple 63 and the cutting blade 61 are also moved upward. At the same time, the spring 85 is tensioned. Through the relative movement of the embroidery machine brake (the brake is not shown), the needle thread or various needle threads are moved from the embroidery base plate 7 to the needle 13 or needles 13, that is, under the level extension feet of the cutting blade 61 and the grapple 63 To enter the capture range or multiple capture ranges. Subsequently, the driving beam 49 descends in the direction of the arrow f. Next, along the side of the needle thread area, between the downwardly moving grabbing hook 63 and the clamping plate 59, the needle 13 is guided to the embroidery base plate 7, and is held and held between the two elements over a long distance. The upper thread of the needle 13 is guided from the direction of the embroidery cloth. When the cutting blade 105 of the slide plate 57 moves, the blade on the cutting blade 61 is close to the embroidery cloth for cutting. This cutting process is supported by the force of the slack spring 85. After the cutting process, the gantry plate 45 on which the embroidery thread cutting and clamping member 55 is mounted is completely moved back to the starting position. The thread end from the needle 13 is securely clamped between the grapple 63 and the clamping plate 59.

If not all the upper threads must be cut at the same time, at some embroidery positions where the upper threads should not be cut, the embroidery thread cutting and clamping member 55 is suspended as follows. By means of the slider 33 and the curved part which has been provided on its front end 41, the upper part of the rocker 87 is swung in the direction on the stage plate 45 according to FIGS. 8a to 8c. Therefore, when the driving beam 49 is subsequently activated, the carriage 71 no longer needs to be raised, because the driving beam 49 no longer abuts against the web 95 of the rocker 87 from below, and the carriage 71 does not move. Therefore, the grappling hook 63 and the cutting blade 61 cannot be moved outward by the clamp plate 49 or the slide plate 57. Next During the cutting process, although the embroidery thread cutting and clamping member 55 moves toward the embroidery orifice 9 together with the adjacent elements, the thread guided from the embroidery cloth toward the needle 13 cannot be grasped, so the thread cannot be cut.
