Description

Embroidery or looping machines for embroidering sequins, borders or the like

technical field

The invention relates to an embroidery machine (Stickmaschine), in particular a shuttle embroidery machine or a looping machine (Stepmaschine), with a device for embroidering borders or the like or with a device for embroidering garment sequins and the like . the

Background technique

Devices for embroidering decorative materials have existed for nearly a hundred years. In the professional literature a distinction is made between so-called border embroidery and sequin and foil embroidery. For fringe embroidery the fringe or strip material is embroidered onto the embroidery base in the desired decorative shape. For bead embroidery and foil embroidery involving embroidery of small items such as costume sequins, sequins and similar items (Sch ner, Freier, Stickereitechninken Leipzig, 1982, pp. 309, 329, FR467 481, CH563 486). If the following only speaks of trim or garment sequins, it is for better understanding. That is, not at all limited by the exemplary designation of trim or apparel sequins.

FR 467 481 describes a zoom embroidery machine having a drive mechanism for manipulating devices for embroidering corduroy, trim, trim, velvet thread, pearl thread and similar decorative materials. Each of these devices has a so-called rim wheel. The trim wheel has a central hole for passing needles and a peripheral hole through which trim or the like to be embroidered onto the cloth is guided. There may also be multiple perimeter holes of different sizes. When embroidering the fringe, the fringe wheel rotates through a hole belt corresponding to the direction of the pattern and alternately embroiders the fringe on the cloth by piercing on one side of the fringe and on the other side. the

CH 563 486 shows an embroidery machine in which a number of edging wheels are controlled by a device program and rotated by racks. the

US Pat. No. 6,957,615 describes a threading machine with a plurality of selvedge wheels, which are driven in rotation by an electric motor via a toothed belt, program-controlled by the device. the

The above examples show that it is complicated to equip an embroidery machine or a looping machine with a border device or to remove it again when it is no longer required or it is desired, for example, to fit a device for embroidering sequins. the

Embroidery of garment sequins or the like has also been known for a long time. For example DE 174 4086 describes sewing so-called ornaments or sheets onto the cloth, wherein the ornaments, also referred to as sheets, are delivered to the needle one by one from a tubular container. Here the needle passes through the hole in each charm and thus secures the charm to the cloth. the

In newer installations the trim material is delivered in belts. Therefore WO 9300468 provides a method and a device for realizing sequin embroidery, wherein a sequin band is conveyed and a sequin is cut off from the band respectively before embroidery. Corresponding devices for embroidering garment sequins or the like are also described by US 3 390 650 and US 5 562 057. the

In EP 1 209 272 a device known as a garment sequin head is described as prior art, in which a first pressurized air cylinder feeds a band of garment sequins through a channel via a ratchet and a lug wheel coupled to the ratchet to a position where the embroidered garment sequins can be secured by the needles of the embroidery machine. A second pressure cylinder drives the cutting unit by which the forward moving garment sequins are cut. These compressed air cylinders can be controlled via four compressed air hoses. The downside is that this garment flash can only allow the embroidery machine to rotate at 200 revolutions per minute. EP 1 209 272 describes a garment flash film head with a single drive for manipulating the feed and cutter. Although this garment glitter head is suitable for the higher speeds of the embroidery machine, a pneumatic adjustment cylinder is always required to bring the garment glitter Engages with a drive rod that extends the entire length of the embroidery machine. the

A drawback of many apparel sequin headers processed with a strip of apparel sequins is that the apparel sequin band may not be easy to insert and there is also the risk of jamming the apparel sequin band. To overcome this drawback, EP 1 561 849 proposes a garment sequin head having an intermittently driven pattern wheel for feeding the garment sequin strip, a guide for the strip partially enclosing the meshing pattern wheel and a cutting device for separately dividing the sequins of the dress before embroidery. In this garment flash head the guide moves away from the front end of the garment glitter strip and the gobo wheel and has a magnet as force element which keeps the guide fixed in the guiding position during operation of the device, but fails when a given reaction force is generated, As a result, the guide body is lifted off the tread wheel. This construction of the apparel flash head enables the front insertion of the apparel flash strip by lifting the guide from the pattern wheel prior to insertion of the apparel flash strip. After inserting the garment glitter strip, the guide body is fixed in the guide position by force means. However, if the clothing flash tape is to be clamped during operation, the guide body is lifted from the clothing flash tape, which also makes the pattern wheel no longer convey the clothing flash tape. For the embroidery machine that is equipped with a lot of such dress flashing heads, the pattern wheel is arranged on a common shaft, and the shaft is coupled on a drive mechanism controlled by the embroidery machine controller. Its disadvantage is that the garment glitter film header can only be switched on or off jointly for embroidering the garment glitter. the

Whereas the clothing glitter head already described by means of EP 1 209 272 has a compressed air cylinder for cutting the clothing glitter, the clothing glitter head according to EP 1 561 849 provides a cutting device with a stationary breakaway edge and an impact plate arranged on the needle bar. The advantage is that there is no need for compressed air cylinders for cutting garment sequins. the

Modern embroidery machines have digit-by-digit embroidery circuits. It allows automatic switching on and off of the embroidery position according to the pattern to be embroidered and the desired color. For example EP 0 634 512 shows an embroidery machine, wherein the embroidery tool of each embroidery position can be coupled and disconnected from the drive mechanism. For this purpose, two or more actuators, for example pneumatic cylinders, are provided for each embroidery position. EP 0 911437 shows a digit-by-digit embroidery circuit in which a single cylinder is sufficient for at least making the needle and the yarn guide of the embroidery position simultaneously switched on. the

By means of EP 1 209 272 the form of garment flashing headers can be driven together with the embroidery machine by a bit-by-bit embroidery controller so that a cyclic change and/or color change can be realized. Thus, for example, the pattern may require that, instead of each garment sequin, for example, every second or third garment sequin be embroidered or, for example, red garment sequins be embroidered with a red thread, blue garment sequins be embroidered with a blue thread, etc. Here, the corresponding embroidery positions and garment flashing film headers are switched on and off via the device controller. But as mentioned above, this dress flash sequence works very slowly. But mainly it is expensive, since it requires at least a special control mechanism and corresponding control lines. the

It has already been stated that it is very time-consuming to convert an embroidery machine that works with a selvedge device into an embroidery machine that works with garment glitter. If it is possible to embroider a design where a first garment sequin is embroidered with red thread and a second garment sequin is embroidered with blue thread, but it is not possible to switch to embroidery trim after embroidering the garment sequin and vice versa. the

Contents of the invention

The object of the present invention is to realize an embroidery machine or looping machine which has an economical device for embroidering trims or garment sequins, but at least partially avoids the above-mentioned disadvantages. Also it is possible to equip the machine in a short time for embroidering the desired form of decoration. Be able to easily convert equipment from one form to another. Furthermore, it is also desirable to be able to run machine programs with different types and colors of decorations without having to change equipment. the

An embroidery machine or looping machine of the above-mentioned form according to the present invention is characterized in that each device has a clutch operated by the needle bar for coupling and a clutch controllable by the device controller for decoupling the device. reset device.

This has the advantage that no cylinders or the like are required for the operation of the device. Instead, the corresponding device is ready for operation by entering the embroidery position. When the embroidery position is in operation, the needle bar moves forward, and the clutch is operated to couple the drive shaft with a drive mechanism that can be controlled by the device controller. the

If the coupled device is a device for embroidering borders, the device controller acts to make the trim orientation correspond to the programming for the pattern to be formed with the trim. But if the coupled device is a device for embroidering apparel sequins, the program determines if and when to embroider apparel sequins. The needle can embroider normally as long as the device controller does not issue a garment sequin feed. But if the machine controller calls for a feed, a garment sequin is fed and then embroidered by the needle. When changing the co-cycle and the color, the device is decoupled again by resetting the device. the

In order to be interchangeable, the device for embroidering trims and the like and the device for embroidering garment sequins and the like advantageously have the same securing and clutching mechanisms. This has the advantage that one form of device can easily be replaced by another. It is also possible to have the device not only for embroidering borders but also for embroidering garment sequins, which is absolutely not possible in the present situation and thus opens up completely new approaches to modern design. This enables the cloth to be embroidered not only with sequins but also with trim and in different colors on one carrier. the

The embroidery machine and looping machine are extremely flexible. It enables more complex patterns that were previously impossible or could only be achieved by hand. Since garment sequins and trims can be embroidered with relatively fast speed, the machine also enables a noble decoration of a modern material for the mass market. the

The invention also relates to other advantageous configurations, which are described below. the

Description of drawings

An exemplary embodiment of the invention will now be described with the aid of the drawing. In the attached picture:

Detailed ways

Figure 1 shows a number of garment sequin headers 10 arranged on a shuttle embroidery machine in an 8/4-cycle (one garment sequin leader 10 for each second embroidery position). They are fastened easily replaceable by means of bolts 14 to an angle bracket 12 of the machine (see FIGS. 1 , 6 and 7 ), wherein guide pins 16 (see FIG. 4 ) ensure precise positioning. A driving device 15 which can be controlled by the device controller is used to drive the clothing flash film head. The drive 15 has a motor 17 , for example a stepper motor, by which a shaft with gears or a pinion 19 extending over the entire length of the device can be driven, by which the garment flash film head 10 can be coupled. A reset device 21 is used for decoupling. The reset device can likewise be controlled by the device controller and essentially consists of a cylinder 23 whose piston 25 is articulated on a lever 27 which pivots an actuating rod 29 . The actuating lever 29 extends over the entire length of the device and has a clamp 30 for each clothing flash leader 10 , which decouples the clothing glitter leader 10 when the reset device 21 is actuated. The needle bar 31 with the needle 33 can also be seen in FIG. 1 . Thus, for the shown clothing glitter shots 10 arranged in an 8/4 cycle, one clothing glitter leader 10 is attached to each of the two needles 33 . Of course, the arrangement of the costume glitter film headers 10 can also be realized with other cyclicities, for example 12/4 cyclicity. Fix a control cam 35 on each needle bar 31 attached to a clothing flashing film head 10, and it is used for coupling clothing flashing film head 10. the

However, instead of the garment flashing head 10 shown in FIG. 1, a selvedge head 10' is also possible, as described below with reference to FIGS. 10 and 11. They can be coupled and decoupled like the clothing flash leader 10 and are designed in the same way. The apparel glitter head 10 can thus be easily replaced with a selvedge head 10'. Not only the garment glitter head 10 but also the selvage head 10' can be provided on the device and work either through the garment sequin head or through the selvage head depending on the task of the pattern to be embroidered. the

It has already been mentioned above that the garment flashing head 10 and the selvage head 10' are constructed identically in terms of coupling and decoupling. Therefore in the following first the common mechanism of the two heads will be described with the aid of FIGS. 2, 4 to 7, and then the special features of the garment glitter head and the trim head will be described in detail. The same reference symbols are used for identical parts or parts with the same function. The following description can therefore also be read with the aid of FIGS. 10 and 11 . the

The clutch 49 has a clutch wheel 51 which, after coupling, meshes with the toothed shaft 19 (see FIG. 1 ) and a gear wheel 53 (see FIG. 7 ) of a drive shaft 57 . The clutch wheel 51 is supported on a lever 55 (see FIGS. 2 to 4 ), which pivots about a drive shaft 57 . A spring 56 works to keep the lever 55 in the position where the clutch wheel 51 is engaged with the pinion 19 . The clutch wheel 51 is in permanent mesh with a gear 53 on a drive shaft 57 . the

The lever 55 has two arms 59 , 61 . On the arm 59, the clutch wheel 51 is rotatably supported and on the other arm 61 there is an on-off switch which can be manipulated by the clamp 30 of the needle bar 31 and the reset device 21 (see FIG. 7 ) for making the clutch 49 on-off. Agency65. the

If the clutch 49 can be actuated directly via the needle rod 31, a switching mechanism 65 for actuating the clutch 49 is preferably used. The switching mechanism 65 is designed in such a way that the lever 55 is held in the coupled position rigidly and not solely by the force of the spring 56 . the

As shown in FIG. 4 , the switching mechanism 65 has an actuating lever 67 on which a control arm 68 is arranged. The actuating lever 67 is pivotable in one direction of rotation via the needle bar 31 and in the other direction of rotation via the resetting device 21 . Described operating lever 67 is connected with a cam disc 69 by shaft 66, and cam disc presses a pin shaft 71 by spring 73. The cam plate 69 is rotatable between two positions which determine the on and off positions of the clutch 49 . The curve 72 (see FIG. 5 ) rises from one location to another until its center and then descends again. The cam 69 is fixed in each position by a spring 73 . the

The movement of the cam disc 69 by the needle bar 31 causes a pivoting movement of the lever 55, whereby the clutch wheel 51 meshes with the toothed shaft 19 (see FIG. 7 ). If the cam plate 69 is moved in the opposite direction by the reset device 21, the clutch wheel 51 is disengaged from the pinion shaft 19 again, but a tooth 75 (see Figures 2 and 4) is embedded in the clutch wheel 51 for locking this clutch wheel. The drive shaft 57 is thus locked via the gear wheel 53 . For a garment sequin head this results in the garment sequin strip 39 being fixed in a position from which, on feed, the garment sequin 13 to be embroidered is brought into the exact position for embroidery. the

Since the apparel glitter head 10 and the trim head 10' (see Figures 10 and 11) are constructed identically, it has the advantage that the same components can be used for both devices. The difference in structure between the two devices is mainly that the drive shaft 57 drives the pattern wheel 37 (see Figure 2) for the clothing flash film head, and drives the edge wheel 85 (see Figure 11) for the edge head through a transmission. the

After describing the common features of apparel glitter headers and trim headers, other constructions of apparel glitter headers will now be described in detail (see Figures 2 to 7). The drive line from the motor 17 , the pinion shaft 19 , the clutch wheel 51 , the gear 53 to the drive shaft 57 has been described above. The drive shaft 57 is supported in the side walls 36 , 38 . A tread wheel 37 is fixedly arranged on the drive shaft 57 . The tread wheel 37 is used to feed the strip of apparel glitter 39 . As can be seen from Figures 2 to 6, the forward movement and cutting of the garment sequins is substantially achieved in the same manner as has been described in EP 1 561 849. Reference is therefore made to this document for details. the

A swing bar 41 (see FIGS. 2 and 4 ) for the guide of the garment glitter strip 39 is pivotally supported below the tread wheel 37 by a pin 43, and has a magnet 45 on its free end, which when When the pendulum 41 is closed after being inserted into the garment glitter strip 39, the magnet is fixedly attracted to a stationary stop 44 made of ferromagnetic material. the

Described clothing flashing film band 39 is inserted into the clothing flashing film head inside easily when opening swing lever 41 by a bobbin tube not shown, positioned at the clothing flashing film head 10. the

The run-off edge 47 is located at the lower end of a mounting plate 46 . Together with the impact plate 48 on the needle bar 31, the breakaway edge 47 forms a cutting device for separating the garment glitter 13 (see FIG. 6). the

However, unlike the garment glitter film leader according to EP 1 561 849, the garment glitter film leader according to the invention is not directly driven, but is driven by a clutch 49, wherein there is also a particularity, this clutch 49 is operated by the needle bar 31 attached to the embroidery position . A separate actuator, for example in the form of a cylinder, is therefore not required for switching on the garment flashing film head 10 . the

The mode of operation of the device for embroidering garment sequins is described below. It is also possible to have only one single device of this type on the embroidery machine, but in practice it is common to work with a number of garment flashers, as already briefly described with reference to FIG. 1 . the

If for example an embroidery machine embroiders with a needle that is not associated with a garment flasher, and now in the embroidery position performs a cycle and color change with a needle, for example associated with every second or third garment flasher of Fig. 1, The clutch 49 is then actuated by the movement of the respective needle bar 31 . The clutch wheel 51 therefore meshes with the pinion 19 . As long as the embroidery program does not require embroidery of a garment sequin, embroider a design as required by the embroidery program. But if the embroidery program calls for a garment glitter to be embroidered, the motor 17 rotates the pinion 19 which itself moves forward one garment glitter 13 via the clutch wheel 51, gear 53, shaft 57 and pattern wheel 37. This garment sequin is cut by the needle bar 31 through the cutting devices 47, 48 and embroidered with some stitches. It is always necessary to control the motor 17 in order to feed a garment glitter 13 . the

If cycles and color changes are to be implemented again, the reset device 21 is actuated by the plant controller. As a result, the piston 25 of the air cylinder 23 oscillates the lever 27 (see FIG. 5 ). This lever itself pivots the actuating lever 29 with the clamp 30 (shown in FIGS. 1 and 7 ) for disengaging the clutch 49 of the feed device 11 . To this end, the gripper 30 presses against the cam 77 of the actuating lever 67 (see FIG. 4 ). As soon as the program has determined the embroidery position with the associated garment glitter leader, the clutch 49 of this garment glitter leader is coupled via the needle bar 31 . the

9 to 11 will also describe the trim device in detail, so no longer relate to the drive line from the motor 17, pinion shaft 19, clutch wheel 51, gear 53 to the drive shaft 57 that has been consistent with the clothing flashing film head. Said selvage head 10' is easily replaceable in the same manner as the clothing glitter head 10 and is fixed on the bracket 12 by bolts 14 (see Figure 1). the

A bevel gear 79 is provided on the drive shaft 57 for the flange head 10', which meshes with another bevel gear 81 which is connected with a toothed belt wheel 83. The toothed belt wheel 83 serves to drive the toothed edge wheel 85 via a toothed belt 87 . the

The trim wheel 87 has a central hole 89 (see FIG. 1 ) through which the embroidery needle 33 passes and at least one peripheral hole 91, 92 through which a trim 95 to be embroidered onto the cloth is guided (see FIG. 1 ). 8 and 9) or similar. Rimming wheels are known from the above-mentioned prior art. Different openings 91 , 92 have different diameters for processing trims of different thicknesses. the

Said selvage head 10' works as follows: when the program requires embroidery of selvage, for example by every second selvage head, for the corresponding embroidery position the clutch 49 is actuated via the needle bar 31 and the respective selvage head starts to embroider the selvage 95. Controlled by the device controller, the selvage wheel 85 is correspondingly aligned with the curve of the pattern and on the other hand the selvage 95 is turned to one side or the other when embroidering one by one, so that the embroidery usually alternates between the selvedges and the selvedges. Realize on one side or the other side, make face thread wrap trimming 95 thus and trim trim is fixedly embroidered on cloth 99 together with shuttle thread 97 (see Fig. 8 and 9). the

After the border pattern has been embroidered, the reset device 21 is actuated by the machine controller, which causes the clutch 49 to be disengaged. At the same time, the trim can be cut and/or clamped by a not shown cutting/clamping device. But cutting can also be done manually. the

In summary, the embroidery machine is equipped with a device for embroidering decorations, namely a garment sequin head (10) for embroidering garment sequins or the like and/or a selvage head for embroidering sequins or the like. These devices are easily replaceable. The device is driven by a drive device (15) controllable by the plant controller. A clutch (49) that can be manipulated by the on-off cam (35) of the needle bar (31) is used to couple the devices. A reset device (21) controllable by the plant controller is used for decoupling. Because the coupling is achieved through the needle bar (31), no special control mechanisms and actuators such as cylinders are required for this purpose. Many devices can be arranged on one embroidery machine, and they are reset by the same common after embroidering garment flashes or embroidery borders. The device is decoupled. the
