Description

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.

Devices for embroidering decorative materials have been around for a hundred years. In the literature, a distinction is made between the so-called soutache and the pearl and bauble embroidery. In the Soutachestickerei cord or band-shaped material is embroidered in the desired decorative form on the embroidery floor. Pearl and bauble embroidery is about embroidering small objects, such as sequins, beads and the like ( Schöner, Freier, Stickereitechniken, Leipzig, 1982, p. 309, 329 . FR 467 481 . CH 563 486 ). If the following is only about strings or sequins, this is for better understanding. With the exemplary naming of strings and sequins so no limitation is intended.

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 aufzusickende on the fabric cord or the like is guided. There may also be several peripheral openings of various sizes. When embroidering the cord, the Soutacheräder be twisted by means of a perforated tape according to the course of the pattern and embroidered the string alternately with stitches on one side and the other side of the string on the fabric.

The CH 563 486 shows an embroidery machine in which a plurality of Soutacherädern are controlled by the machine program and rotated by racks.

The US 6,957,615 describes a quilting machine with a plurality of Soutacherädern that are rotated by the engine program controlled by a motor via toothed belt.

The examples given show that it is complicated to equip embroidery and quilting machines with soutaching devices or to remove them again when they are no longer needed or, for example, to remove them. the desire exists to mount devices for embroidering sequins.

The embroidery of sequins and the like has long been known. For example, describes the DE 174086 the sewing of so-called flakes or scales on fabrics, 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.

In newer devices, 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.

In the EP 1209 272 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. A disadvantage is mentioned that 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. Although 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.

A disadvantage of many sequin heads, which process sequins in the form of a band, is that the sequin bands can not be easily inserted and that there is also a risk of jamming of the sequin bands. To remedy this disadvantage, sees 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. In this sequin head, 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. In an embroidery machine equipped with a multiplicity of such sequin heads, 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. This has the disadvantage that the Sequin heads can only be switched on and off together to embroider sequins.

While referring to the EP 1209 272 first described sequencer head has a pneumatic cylinder to cut off the sequins, sees the sequin head according to the EP 1 561 849 a cutting device with a stationary knock-off edge and a striking plate, which is arranged on the needle plunger. This has the advantage that no compressed air cylinder is necessary for cutting off the sequins.

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. For example, shows the EP 0 634 512 an embroidery machine, in which the embroidery tools each embroidery point to the drive means and can be disconnected. For this purpose, 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. Thus, for example. require the pattern that instead of each sequin head z.Bsp. only every second or third sequin head embroider or that z.Bsp. red sequins with red thread, blue sequins with blue thread, etc. to be embroidered. The corresponding embroidery points and sequin heads are switched on and off by the machine control. However, as already mentioned in the introduction, such sequin heads sometimes work very slowly. Above all, they are expensive because they need at least a special control body and appropriate control lines.

It has already been stated that it is very time consuming to convert embroidery machines that work with soutachevorrichtungen to work with sequin heads. Although it was possible to embroider a pattern where a first sequin head with red thread and a second sequin head with blue thread embroidered, but it was not possible to change after embroidering sequins on the embroidery of strings and vice versa.

It is an object of the present invention to provide an embroidery or quilting machine with inexpensive devices for embroidering cords or sequins, but the disadvantages mentioned above are at least partially avoided. It should be possible to equip the machine in a short time to embroider ornaments of the desired type. Also, a conversion from one kind to another should be easily possible. Furthermore, it would be desirable to be able to work without changing over with different types and colors of ornaments controlled by the machine program.

According to the invention, 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.

This has the advantage that no pneumatic cylinders or the like are needed to start up the respective device. The respective device is rather put into readiness by the commissioning of the embroidery point. When the needle bar is moved forward after the embroidery station is started, the clutch is operated to couple the drive shaft with a drive member controllable by the machine controller.

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.

In order to be interchangeable, 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.

Further advantageous embodiments of the invention are described in claims 4 to 17.

FIG. 1 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. In 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 arrangement of the sequin heads 10 can of course also in other rapports, z. Ex. 12/4 - Repeats done. At each needle tappet 31, which is associated with a sequin head 10, a control cam 35 is attached, which serves to engage the sequin head 10.

In place of in Fig. 1 but it could also be Soutacheköpfe 10 ', as described below with reference to the FIGS. 10 and 11 to be discribed. These are like the Sequin heads 10 on and disengaged and configured in this regard the same. Sequins heads 10 are thus easily interchangeable with Soutacheköpfen 10 '. It is also possible to arrange both sequin heads 10 and base head 10 'on the machine and to work with the sequin heads or with the Soutacheköpfen depending on the specifications of the pattern to be embroidered.

It has just been mentioned that the sequin heads 10 and the Soutacheköpfe 10 'are designed with respect to the Ein- and disengageability equal. Subsequently, therefore, first of the two heads common mechanism with reference to the Figures 2 . 4 to 7 described, whereupon the special features of the sequin head and the Soutachekopfes will be discussed in more detail. The same reference numbers are used for the same parts or parts with the same function. The The following description can thus also with reference to the FIGS. 10 and 11 to be read.

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

Although a direct actuation of the clutch 49 would be possible by the needle plunger 31, 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.

As the FIG. 4 shows, 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.

The movement of the cam disc 69 caused by the needle plunger 31 causes the lever 55 to pivot, so that the coupling wheel 51 engages the toothed shaft 19 ( Fig. 7 ). If the cam 69 is moved by the return device 21 in the opposite direction, the coupling wheel 51 comes back out of engagement with the toothed shaft 19, but a tooth 75 (FIG. Fig. 2 and 4 ) engages the clutch wheel 51 to block it. As a result, the drive shaft 57 is blocked via the gear 53. In the case of a sequin head, this has the consequence that the sequin band 39 is held in a position from which the sequin 13 to be stitched then arrives in the correct position for embroidering during a feed.

So far are 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 ).

After this description of the common features of sequin head and Soutachekopf now the further construction of the sequin head ( Fig. 2 to 7 ). Previously, the drive train from the engine 17, gear shaft 19, clutch 51, gear 53 to the drive shaft 57 has already been described. The drive shaft 57 is mounted in the side walls 36, 38. On the drive shaft 57, a cam 37 is fixed. The Warzenrad 37 serves to advance the sequin belt 39th As from the FIGS. 2 to 6 can be seen, the advancement and cutting of the sequins takes place in substantially the same manner as already in the EP 1561849 has been described. For details, therefore, reference may optionally be made to this document.

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 feromagnetischem 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.

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 ).

In contrast to the sequin head according to EP 1561849 but the sequin head according to the invention is not driven directly, but via the clutch 49, which also has the peculiarity that the clutch 49 is actuated by the needle tappet 31 of the associated embroidery point. It is thus to turn on the sequin head 10 no separate actuator z.Bsp. necessary in the form of a pneumatic cylinder.

The operation of the apparatus for embroidering sequins will now be described below. It would be possible to provide only a single such device on an embroidery machine, but in practice a variety of sequin heads are usually used, as already described with reference to FIG Fig. 1 was briefly executed.

For example, embroidering the embroidery machine with needles, which are not associated with Sequin heads, and is now a Rapport- or color change on embroidery with Needles, which z.Bsp. with every second or third sequin head of Fig.1 are associated, 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. As long as the embroidery program does not require embroidering a sequin, embroidery program is required as embroidered pattern front. But if the embroidery program requires embroidering a sequin, 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. This is separated by the needle plunger 31 by means of the separating device 47, 48 and stitched with some pinholes. In this way, depending on the embroidery program, more sequins 13 are embroidered. To advance a sequin 13, the control of the motor 17 is always necessary.

If in turn a repeat or color change take place, 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.

With reference to the FIGS. 9 to 11 Now, the Soutachevorrichtung will be described in more detail, as far as it does not already the same with the sequin head drive train of motor 17, gear shaft 19, clutch 51, gear 53 to the drive shaft 57 relates. The Soutacheköpfe 10 'are easily replaceable in the same way as the sequin heads 10 with screws 14 on the support 12 (FIG. Fig. 1 ) attachable.

When Soutachekopf 10 'a bevel gear 79 is disposed on the drive shaft 57, which is in engagement with a further bevel gear 81, which with a toothed belt 83rd connected is. The toothed belt wheel 83 is used to drive the toothed Soutacherads 85 by means of a toothed belt 87th

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 Soutacheköpfe begin with the embroidery of the cords 95. Under the control of the machine control, the Soutacheräder 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 ).

After the stitching of the cord pattern, the reset mechanism 21 is actuated by the machine control, which results in disengaging the clutch 49. At the same time, the cord can be cut and / or clamped by an unillustrated cutting / clamping device. The cutting can also be done manually.

In summary, the following can be stated: 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. On an embroidery machine, 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.
