Definitions

the present invention relates to an embroidery machine, in particular a Schifflitickmaschine, or quilting machine with devices for embroidering cords or the like or of devices for embroidering sequins and the like.
the FR 467 481 describes a pantograph embroidery machine with a drive member for operating devices for embroidering cords, cords, strands, chenille, bead cords and similar decorative materials.
Each of these devices has a so-called Soutacherad.
the Soutacherad has a central opening for the passage of the embroidery needle and a peripheral opening through which the réellesickende on the fabric cord or the like is guided. There may also be several peripheral openings of various sizes.
the CH 563 486 shows an embroidery machine in which a plurality of Soutacheziern are controlled by the machine program and rotated by racks.
the US 6,957,615 describes a quilting machine with a plurality of Soutacheziern that are rotated by the engine program controlled by a motor via toothed belt.
the embroidery of sequins and the like has long been known.
the needle, the baubles, also called sequins are fed individually from a tubular container.
the needle pierces through a hole provided in each bauble and attaches it to the fabric.
the decorative material is supplied in the form of a belt. That's how it shows WO 9300468 a method and apparatus for performing bead embroidery in which a beaded tape is fed and one bead is cut from the tape prior to embroidering.
Corresponding devices for embroidering sequins or the like are also characterized by US 3,390,650 and US 5 562 057 described.
the prior art describes a device called a sequin head, in which a first pneumatic cylinder advances a sequin belt through a channel to a position at which the sequin can be stitched with the needle of the embroidery machine via a ratchet wheel and a cam wheel coupled to the ratchet wheel.
a second impression cylinder drives a cutting device on, with which the driven sequin can be cut off.
the compressed air cylinders are controlled by four compressed air hoses.
this sequin head only allows a number of revolutions of the embroidery machine of 200 revolutions per minute.
the EP 1209 272 then describes a sequin head, which provides a single drive for actuating the feed device and the cutting device.
this sequin head is suitable for higher embroidery machine speeds, it still requires a pneumatic adjustment cylinder to bring the sequin head from the rest position to the working position, and a control cylinder to engage the sequin head with a drive rod extending the full length of the embroidery machine bring to.
the EP 1 561 849 a sequin head which has an intermittently driven Warzenrad for advancing the tape, a Warzenrad partially encompassing guide for the tape and a separator for separating a sequin each before picking.
the guide is movable away from the front side of the belt and the warp wheel and has a magnet as a force element, which keeps the guide in the operation of the device in guiding position, but is ineffective at the occurrence of a predetermined reaction force, so that the guide is lifted from the warp wheel .
This embodiment of the sequin head makes it possible to introduce the tape from the front by the guide is lifted from the worm wheel before inserting the tape. After insertion of the tape, the guide is held by the force element in the guiding position. But should the band jam during operation, the guide is lifted off the belt, which also means that the warp wheel no longer supports the belt.
the warp wheels are arranged on a common shaft, which is coupled to a drive element which can be controlled by the embroidery machine control.
a drive element which can be controlled by the embroidery machine control.
Modern embroidery machines have single embroidery circuits. This makes it possible to automatically switch embroidery positions on and off depending on the type of patterns to be embroidered and the desired color.
the EP 0 634 512 an embroidery machine, in which the embroidery tools each embroidery point to the drive means and can be disconnected.
two or more actuators for example pneumatic cylinders, are arranged for each embroidery point.
the EP 0 911437 shows a single embroidery circuit, in which a single pneumatic cylinder is sufficient to switch at least needle and thread guide the embroidery site at the same time.
Sequin heads of with reference to the EP 1209 272 described type can be operated together with embroidery machines with single embroidery control so that a Rapport- and / or a color change is possible.
a Rapport- and / or a color change is possible.
Sequin heads of with reference to the EP 1209 272 described type can be operated together with embroidery machines with single embroidery control so that a Rapport- and / or a color change is possible.
the corresponding embroidery points and sequin heads are switched on and off by the machine control.
sequin heads sometimes work very slowly. Above all, they are expensive because they need at least a special control body and appropriate control lines.
an embroidery or quilting machine of the type mentioned is characterized in that each device has an operable by the needle plunger clutch for engaging and that a return device for disengaging the device is provided.
the machine control When the engaged device is a lace-embroidering device, the machine control causes the line to be aligned in accordance with the program's program for the lace-forming pattern. However, if the engaged device is a sequin picking device, then the program determines if and when sequins are being stitched. As long as the machine control does not trigger a feed of a sequin, the needle can stitch normally. But requires the machine control a feed, so a sequin is advanced and then hooked by the needle. During a repeat or color change, the device is disengaged again by the return device.
the sequin embroidering apparatuses and the like, and the lace embroidering apparatuses and the like advantageously have the same attachment means and coupling means. This has the advantage that one type of device can be easily replaced by the other type. It is also possible that the machine has both lace cording and sequin embroidery devices, which has never before been the case and opens up completely new possibilities for fashion designers. So it is possible to embroider fabrics in a single stretch with both sequins and with strings and this in different colors.
the embroidery or quilting machine is extremely flexible. It allows the execution of elaborate patterns that were previously impossible or only executed by hand. Since sequins and cords can be embroidered at relatively high speeds, the machine allows a noble equipment of fashion fabrics also for mass markets.
FIG. 12 shows a number of sequin heads 10 arranged in a 8/4 repeat (one sequin head 10 for every other embroidery point) on a ski-knitting machine. These are easily interchangeable with screws 14 on the angular support 12 (FIG. Fig. 1, 6 and 7 ) of the machine, with guide pins 16 ( Fig. 4 ) ensure accurate placement.
the drive of the sequin heads is controlled by the machine control drive means 15.
the drive means 15 has a motor 17, z.Bsp.
Stepping motor with which over the entire machine length extending shaft with gears or a toothed shaft 19 can be driven, with which the sequin heads 10 can be coupled.
This is also controlled by the machine control and consists essentially of a pneumatic cylinder 23, the piston 25 is articulated to a lever 27 which can pivot a shift rod 29.
the shift rod 29 extends over the entire length of the machine and has at each sequin head 10 a gripper 30 which disengages the sequin head 10 upon actuation of the return device 21.
FIG. 1 are also the needle plunger 31 with the needles 33 can be seen. In the illustrated arrangement of the sequin heads 10 in the 8/4 repeat, every second needle 33 is thus assigned to a sequin head 10.
the coupling 49 has a coupling wheel 51 which, after engagement with a toothed shaft 19 (FIG. Fig.1 ) and a gear 53 of the drive shaft 57 is engaged ( Fig. 7 ).
the coupling wheel 51 is on the lever 55 ( Fig. 2 to 4 ), which is pivotable about the drive shaft 57.
a spring 56 tends to hold the lever 55 in a position in which the coupling wheel 51 is in engagement with the toothed shaft 19.
the coupling wheel 51 is in permanent engagement with the gear 53, which sits on the drive shaft 57.
the lever 55 has two arms 59, 61. On the arm 59, the coupling wheel 51 is rotatably mounted and on the other arm 61 is one of the needle plunger 31 and the gripper 30 of the return device 21 (FIGS. Fig. 7 ) operable switching member 65 for switching on and off of the coupling 49th
the use of a switching member 65 for actuating the clutch 49 is preferred.
the switching member 65 is configured so that the lever 55 is held rigidly and not merely by the force of the spring 56 in the engaged position.
the switching member 65 an actuating lever 67, on which a switching arm 68 is arranged.
the actuating lever 67 is pivotable in one direction of rotation by the needle plunger 31 and in the other direction of rotation by the return device 21.
the operating lever 67 is connected via the shaft 66 with a cam 69, which is pressed by the spring 73 against a pin 71.
the cam 69 is rotatable between two positions, which set the closed position or the off position of the clutch 49. From one of these positions to the other, the curved path 72 rises ( Fig. 5 ) to her Middle and then falls off again. In each of these positions, the cam 69 is held by the spring 73.
sequin head 10 and Soutachekopf 10 '( 10 and 11 ) has the same structure, which also has the advantage that the same parts can be used for both devices.
the difference in the construction of the two devices consists essentially in the fact that the drive shaft 57 in the sequin head, the cam 37 ( Fig. 2 ) drives, with the Soutachekopf however over a transmission the Soutacherad 85 ( Figure 11 ).
a serving as a guide for the sequin band 39 pivot lever 41 ( Fig. 2 and 4 ), which is mounted pivotably by means of a pin 43 below the cam wheel 37, has at its free end a magnet 45 which adheres to a stationary stop 44 of feromagneticianm material when the pivot lever 41 is closed after insertion of the sequin belt 39.
the sequin belt 39 can be easily inserted into the sequin head from an unillustrated spool, which is located above the sequin head 10, with the pivot lever 41 open.
a cutting device for separating the sequin 13 At the lower end of a mounting plate 46 is the knock-off edge 47.
the knock-off edge 47 together with the striking plate 48 on the needle plunger 31, a cutting device for separating the sequin 13 (FIG. Fig. 6 ).
the clutch 49 is actuated by the movement of the respective needle plunger 31.
the clutch wheel 51 thus comes into engagement with the gear shaft 19.
the motor 17 rotates the toothed shaft 19, which in turn advances a paillette 13 via the coupling wheel 51, the toothed wheel 53, the shaft 57 and the cam wheel 37.
the reset device 21 is actuated by the machine control. This has the consequence that the piston 25 of the pneumatic cylinder 23 pivots the lever 27 ( Fig. 5 ). This in turn pivots the shift rod 29 with the grippers 30 (in Fig.1 and 7 visible) to turn off the coupling 49 of the feed device 11.
the gripper 30 presses for this purpose on the cam 77 (FIG. Fig. 4 Thereafter, if the program has determined embroidery sites with associated sequin heads, the couplings 49 of these sequin heads are engaged by the needle plungers 31.
the Soutacherad 87 has a central opening 89 for the passage of the embroidery needle 33 ( Fig.1 ) and at least one peripheral opening 91, 92 through which the cord 95 (FIG. 8 and 9 ) or the like is guided.
Souta wheels are known from the introductory cited prior art.
the various openings 91, 92 have different diameters in order to process cords of different thickness.
the Soutacheköpfe 10 'work as follows: If the program requires the embroidery of strings, z.Bsp. through each second Soutachekopf, the clutches 49 are actuated at the corresponding embroidery sites by the needle plunger 31 and the corresponding Soutachekmü begin with the embroidery of the cords 95. Under the control of the machine control, the Soutachegan 85 aligned according to the curve of the pattern and on the other hand, the string 95 deflected on one or the other side in the individual stitches, so that the stitches are usually done alternately on one or the other side of the string, so that the needle thread 93, the cord 95 wrapped and this together with the shuttle thread 97 on the Fabric 99 ( 8 and 9 ).
the reset mechanism 21 is actuated by the machine control, which results in disengaging the clutch 49.
the cord can be cut and / or clamped by an unillustrated cutting / clamping device. The cutting can also be done manually.
the embroidery machine is equipped with devices for embroidering ornaments, namely with sequin heads (10) for embroidering sequins and the like and / or Soutacheköpfen for embroidery of strings and the like. These devices are easily replaceable.
the drive of the devices is carried out by a controllable by the machine control drive means (15).
a clutch (49) which is actuated by a switching cam (35), the needle ram (31), serves to engage the respective device.
the decoupling is controlled by the machine control reset device (21). Because the engagement takes place by the needle plunger (31), no special control organs and actuators such as pneumatic cylinders are necessary for this.
a plurality of devices can be arranged, which can be disengaged after the embroidery of the sequins or the embroidery of strings by the same common return device.
