Method and device for applying substance to embroidery, and embroidery machine with application device

The present invention relates to a method of applying at least one substance to a embroidery base in accordance with a pre-programmed pattern using an embroidery machine. Further, the invention relates to a device for applying a substance to an embroidery base for an embroidery machine, in particular a shuttle embroidery machine. The invention also relates to an embroidery machine comprising a plurality of needle positions, in particular a shuttle embroidery machine or a multi-head embroidery machine, comprising at least one device for applying a substance, in particular an ejection device, preferably a plurality of ejection devices.

The modern automatic embroidery machine can be equipped with a variety of attachments, such as sequins and sash devices for embroidering sequins, decorative cords, beads, etc. onto the base of the embroidery. This makes it possible to produce a variety of complex embroidery products. Since the precise position of the embroidery base relative to the needle position is almost impossible over the entire width, there has been no satisfactory industrial potential for embroidering a patterned embroidery base with a large or multi-head embroidery machine. Here, it is also important how the embroidery base is held in the embroidery frame. If manually operated, it is not possible to achieve the required precision by gripping a fabric that is often several meters wide. However, even if the fabric is spread from the roller or the frame of the holding frame, distortion occurs in the width direction of the fabric. One consequence of this is that it is not possible to accurately depict or embroider the fabric pattern (printing, printing or weaving) on the front side. Since the distortion in the fabric cannot be easily corrected, the precise positioning of the pattern using the sensor does not help.

Known devices are described, for example, in the documents GB 303 342, EP 1 496 146 A1 and DE 10 239 192 A1.

Patent Specification GB 303 342 discloses an early joint method of making a flower pattern wherein the first incomplete portion of the design is produced by weaving on a loom, the second incomplete portion of which is applied using other techniques such as printing. And complementary to the first incomplete part.

Patent application EP 1 496 146 A1 shows an apparatus for an automated method. The method is equipped with a first workstation comprising a loom and a second workstation behind it comprising at least one handpiece for embroidering and/or applying other decorative elements. According to its disclosure, the fabric produced on the loom can be loaded directly onto the embroidery machine or other application machine without cutting. The pattern thus woven and the subsequent decoration can be automatically correlated with each other.

Document DE 10 239 192 A1 discloses a device for the subsequent decoration of textiles. With this device, it is possible to realize a large-area decoration of the textile without repeating. Of course, it is also possible to apply different application techniques simultaneously or continuously, for example in the form of a linear and other decorative method on the area of the fabric provided for this purpose. To this end, the conveyor belt device grips the fabric to be treated or to be decorated laterally and moves it in the longitudinal direction. At least one handpiece is mounted at a distance from the fabric, and the handpiece is moved over the guided fabric in accordance with a predetermined pattern by means of a linear guide.

It is worthwhile to automatically embroider, print or otherwise assemble the fabric with the desired substance or mixture of substances. However, in the automatic embroidery machine, quality defects occur due to improper covering and/or fitting of the embroidery pattern and the printed pattern. During the transfer of the embroidery machine or embroidery program to the printing machine or printing program or vice versa, the embroidery material is re-clamped, or the embroidery frame is repositioned on the second machine, or moved to other working positions, embroidery patterns and printed patterns There is often a matching error. Deviations from the original plan are extremely destructive in most cases, which can lead to high defect rates and detrimental product values.

It is an object of the present invention to create a method, apparatus and embroidery machine of the type initially cited which is suitable for embroidering and applying in particular dyeing patterns, but which wholly or at least partially obviate the aforementioned drawbacks of prior devices. Further media, particularly sprayable fluids, are also desirable embroidery bases that can be applied directly to the embroidery machine.

According to the invention, the above object is achieved by a method for applying at least one substance in a pre-programmed pattern by means of an embroidery machine preferably comprising a plurality of needle positions for one or more associated embroidery needles.

In the context of the present invention, a substance preferably means one or more substances which are soluble, suspended or dispersed in a solvent or solvent mixture.

The substance or medium in which the substance is dissolved, suspended or dispersed can be applied using a corresponding tool or application device, such as a spray gun or a barrel having a front end opening and in contact with the embroidery base. Advantageously, the application tool is a spray gun or spray device fixedly positioned at a defined position on the embroidery machine frame, preferably at a distance from the embroidery base. Due to the defined position of the application device relative to the embroidery point or the needle position, it is possible to print, organize or equip the material at a previously defined position of the embroidery base by means of an embroidery machine program control.

An advantage of this method is that the embroidery base can be embroidered with at least one thread and exposed, and the same equipment or substance is used to eject the substance. It is also possible to process the thread that has just been embroidered, or to embroider the thread on the surface of the embroidered base that has just been treated. A variety of substances (ink, primer, adhesive, etc.) can be applied here. With the technique according to the invention, the position of the substance can be precisely applied to the carrier material. Thereby, the embroidery and the substance can be accurately positioned on the carrier material. In particular, the embroidery pattern and the application or the printing pattern can be effectively applied to the embroidery base in a predetermined mutual relationship, with a predetermined overlap in the case of application. According to the method of the present invention, an expensive measuring and/or control system is not required to accurately determine the position of the already embroidered thread or the pattern or print that has been applied, and then move the embroidery base to the desired position relative to the ejection point or stitch point. position. The ejection point and the stitch point, i.e., the position at which the ejection nozzle and the lancet operate on the embroidery base, are defined by the position of the ejection device or needle position.

According to a preferred embodiment, the application device is formed by an injection device. The spray device can be mounted on the embroidery machine in accordance with the present invention and aligned with the embroidery base. The advantages of the spray device are relatively small, low cost, and durable, especially when compared to ink jet printers. The spray device is also less prone to error, which is a great advantage for the centralized and continuous application of the embroidery machine.

The spraying device according to the present invention allows a combined embroidery and spraying method to apply a variety of materials, preferably a spray gun. It is possible to apply one or more substances precisely to the embroidered product. Thereby, the embroidery can be accurately positioned, and further substances can be accurately positioned on the embroidery article.

The advantage of the embroidery machine is that it is very flexible and can perform tasks that cannot be performed on existing embroidery machines, and must require labor-intensive preliminary and/or intermediate work that requires manual operation and/or requires other machines. To be done. In particular, the embroidery machine according to the present invention can realize a complicated combination of an embroidery pattern and a printing pattern, which was previously impossible to produce or must be manually operated for production. Since the combination design of various types of embroidery patterns and printing patterns can be embroidered and applied at high speed, particularly jetting, the embroidery machine can realize a high quality processing of a large number of fashionable fabrics required for the production market. In particular, the present invention eliminates the need for intensive labor and eliminates the need for frequent inaccurate adjustments, eliminating the need to clamp the embroidery base to the embroidery machine or to subsequently process the machine, in order to apply the pattern applied in the first step, for example The printing pattern is aligned or oriented relative to the second pattern to be applied, in particular the embroidery pattern.

Advantageously, the embroidery machine is characterized in that a plurality of application devices, in particular ejection devices, are repeatedly arranged in a specific pattern with the plurality of stitch points.

Preferably, the at least one application device or the plurality of application devices are disposed on the same side of the one or more needle tappets with respect to the channel of the embroidery base.

It is conceivable that at least one application device and one or more needle tappets are located on opposite sides of the passage of the embroidery base.

In one embodiment, the application device is an ejection device, the embroidery machine being equipped with at least one trap for supplementing the injected material, preferably the trap comprises at least one funnel, a suction conduit and a water collection cartridge.

Suitably, the injection device and the trap, ie the spray device, are paired with a trap, ie cooperate with each other.

Advantageously, a plurality of application devices, in particular a plurality of injection devices, that can be controlled by a common control system are preferably integrated in the embroidery program.

Exemplary embodiments of the present invention are described in more detail below with reference to the drawings, which are schematically depicted.

Figure 1 shows the support 11 of the shuttle embroidery machine with the needle position 17 mounted thereon. The needle position 17 includes a needle tappet 27 that is movable back and forth, on which a needle (not shown in Fig. 1) is disposed. A needle plate 12 is provided in front of the needle lifter 27, and a shuttle holding portion 13 is attached to the rear of the needle plate 12. A shuttle (not shown in Fig. 1) is mounted in the shuttle holding portion 13, and the shuttle can be moved up and down by a driver bar not shown in detail. The above-described parts and their functions can be readily as known to those skilled in the art from the relevant patent documents, so they need no further explanation. When the embroidery machine is in operation, an embroidery base or fabric 15 (shown by a chain line in the figure) in the form of a woven fabric is held in front of the needle board 12. Thereby, the needle plate 12 forms the bearing surface of the embroidery base 15. According to the prior art, the embroidery base 15 is clamped to the creel or the embroidery frame. Preferably, the creel or the embroidery frame is moved in the X and Y directions under computer control.

The coordinate system referenced here is a Cartesian coordinate system with three mutually orthogonal axes, labeled X, Y and Z, which intersect at the origin.

The embroidery machine according to the present invention is mounted with a spray head 19. The ejection head 19 is disposed above the needle position 17 on the module holder 23. The spray head 19 is attached to the module carrier 23 via a fixing device not shown in detail. The fixing means of the ejection head 19 includes adjustment means for adjusting the ejection head 19 in the direction of the embroidery base, that is, in the Z direction. The adjustment means may comprise a support member, the spray head 19 being movably mounted on the support member, i.e., in a sliding manner.

Advantageously, the securing means comprise guiding means, such as in the form of a linear guiding element, such as a rail, the slider being movably mounted above the rail. The slider may be a support and the spray head is disposed on the slider. However, it is conceivable that the guiding device can also be mounted directly on the spray head, so that no separate support is required. The slider or the spray head can be fixed to the guiding element with suitable fixing means. Preferably, the screw is coupled to the slider to secure the position of the spray head relative to the support member, thereby accurately securing the position of the embroidery base. The screw can be locked by the lock nut. However, it is also possible to provide a motor drive adjustment device that is directly controlled by the control system of the embroidery machine. Maintaining a precise distance from the opening of the nozzle to the embroidery base is important to control the width of the spout of the ejected liquid medium applied to the embroidery base.

Since the spray head 19 and the needle position 17, in particular the nozzle 33 and the needle tappet 27, are fixed to the common module carrier 23 or simply fixed to the embroidery frame, the stitch point 29 and the injection point 35 can be pre-defined relative Location to choose.

The injection device 37 will be described in more detail with reference to Figures 2 to 4. The spraying device 37 comprises at least one spray head 19 having a nozzle 33 and preferably a trap 39. Advantageously, the spray head 19 and its associated catcher 39 are disposed directly opposite each other in front of and behind the embroidery base, whereby excess spray material passing through the embroidery base can be replenished through the trap 39. The smooth running of the embroidery machine is important because the blasting material passing through the embroidery base will otherwise stain the embroidery machine. The surrounding air is also unacceptably contaminated.

Preferably, a trap 39 is provided on the side of the embroidery base 15 for each of the ejection heads 19, which faces away from the ejection head 19. The collecting opening 41 of the trap 39 is here directly towards the outlet of the nozzle 33. The collection opening 41 is preferably guided to the narrow end opening 43 via the funnel-shaped basin portion 42 and into a water suction tube (not shown) which is suitably further introduced into the water collection container. A suction mechanism may be provided that efficiently draws excess material material trapped within the funnel into the water collection container.

Advantageously, as the spray head 19, a marking gun, an automatic spray gun, an air spray gun, an airless spray gun or the like is used, preferably a commercially available device.

Figure 4 shows some details of the marking spray gun 19. The connecting line 45 serves to supply the material to be atomized, ie the substance to be sprayed, which is advantageously presented as a liquid, although applicable can also be embodied as a powder. These materials, such as dyes, paints or adhesives, are preferably delivered from the pressurized storage container to the marking lance 19. The jet air (optionally it may be another medium or a mixture of different media) is introduced via a connecting line 47. The effect of the supplied jet air is to atomize the substance to be applied.

Additional connection lines 49 are used to control the spraying process. Line 49 is suitable for controlling the gas supply. Using control air, the valve within the spray head 19 can open or shut off the injection function to at least interrupt the supply of the substance to be applied and/or the supply of atomizing air to the nozzle. Preferably, the valve is electrically controlled directly so that short time switching is possible.

An outer nozzle needle structure 51 is coupled to the needle for controlling the passage through the nozzle outlet. In particular, by providing the nozzle needle, the outlet opening can be reduced or enlarged, so that the amount of discharged material can be adjusted.

As with the spray head 19, the embroidery machine can be equipped with other accessories, such as a sequin or ribbon unit 21. Preferably, the spray head, sequins or sash unit 21 can be mounted on the module carrier 23 in a specific pattern.

The ejection head 19 according to the present invention can also be mounted on a shuttle embroidery machine or a multi-head embroidery machine. A multi-head embroidery machine typically has a plurality of embroidery heads, each having a plurality of needle positions, thereby forming a plurality of stitch points 29.

The following description relates to an injection method using the injection device 37. A substance is sprayed or atomized here. Thus, the spraying device is used to spray or atomize the substance. The terms spray and atomization preferably mean that the fluid is finely differentiated into droplets or particles, and their subsequent or simultaneous distribution.

Preferably, the substance to be applied is mixed with the jet air. The substance to be sprayed will be atomized by mixing, and simultaneous or subsequent diffusion. A spray head having such a function can also be called a two-substance nozzle or a pneumatic atomizer.

Advantageously, said mixing takes place before the common nozzle outlet of the mixture, in the gun housing of the so-called internal mixing chamber. The injected air and substance to be applied are introduced into the mixing chamber under a certain pressure and mixed under a certain pressure, whereby the pressure substances are atomized at the common nozzle outlet. The mixing of the fluid medium and gas containing the substance to be applied may alternatively occur outside of the nozzle, which is referred to as external mixing. To this end, the jet air and the substance to be applied are pushed through the separate nozzle outlets substantially in the axial direction of the nozzle. The two media mix at the outlet to form droplets of atomized material.

Alternatively, the two-substance nozzle can also be replaced by a single-substance nozzle. The single-substance nozzle applies a substance by pressure energy and does not mix with any atomizing gas. In a simple embodiment, the single substance nozzle has substantially a pore through which the substance to be applied, in this case as a fluid, is formed at a particular velocity.

The substance to be applied is pressurized in the container, preferably pressurized with air (for example connected to a compressor), and transported to a spray head through a material transport system, ie a hose line, or several hose lines Delivered to each spray head. Each head is controlled via at least one on/off valve. Thereby, the passage to the nozzle opening is opened or cut, so that the opening or closing of the injection program can be switched. Advantageously, the valve is electromagnetically controlled so that the switching time can be particularly shortened.

In addition, typically atomizing air will be directed into the material stream, whereby the substance to be applied can be finely sprayed onto the embroidery base. Compressed air can be used as atomizing air. This technique allows, for example, a fine dyeing process to be produced, so that there are almost no restrictions on the design.

Control commands and various applicable injection parameters are advantageously programmable and integrated into existing embroidery machine programs.

In the method according to the invention, it is possible to use a spray gun having a relatively small size, for example a length of 15 cm, preferably 10 cm, corresponding to a small cross-section block. Since the size of the ejection head 19 is small, first, a plurality of ejection heads 19 can be integrated in the embroidery machine; second, the distance from the stitch point 29 to the ejection point 35 can be kept as small as possible.

With the aforementioned ejection device, a dot, line or area mark can be applied depending on whether or not the embroidery base undergoes movement relative to the nozzle during the ejection process.

Advantageously, the plurality of spray devices are arranged in a particular pattern with the needle position.

If a plurality of spraying devices are employed and/or different substances in the plurality of supply containers are employed, different substances may be applied alternately or simultaneously, for example color conversion is possible. The machine can be controlled via an embroidery machine program.

By means of the spraying device, any liquid substance, as well as fine pigments according to the size of the nozzle, can be applied to the embroidery base, i.e. whether the unprocessed embroidery base or the partially embroidered embroidery base. The use of particle suspensions is possible, for example using an external mixing gun. Depending on the principle of the jet pump, the spraying device comprises, for example, a single substance atomizer for, for example, a liquid substance, or a two substance atomizer for a fluid having particles which, as previously described, can be used as a propellant.

In order to prevent contamination and improve the stability of the process, a flushing system can be integrated. This flushing system may, for example, include a connector for providing a flushing medium to clean the nozzle after the final spraying process.

The injection device of Figures 5 and 6 differs substantially from that of Figure 4 in that two connection points 53a and 53b are provided for the storage container 55. The joints 53a and 53b are fitted with a self-locking valve 57 that automatically closes the opening 59 of the joint when the storage container is not connected, and opens the opening 59 when the storage container is connected to the opening 59. In order to achieve a rapid change of the storage container 55, the storage container 55 and the connection points 53a, 53b are mounted with quick closing means, such as a plug-in closure, not shown in detail.

Since the substance (memory effect) in the previously connected container still remains in the ejection device, in order to achieve color conversion without a tailing effect, the inside of the line between the ejection device and the connection points 53a, 53b can be rinsed. The collection container 61 is connected to one end of the connection point 53a, and the positive pressure source 63 or the cleaning solution is connected to the other connection point 53b. Thereby, the material remaining in the pipeline can be blown or washed out and replenished in the collecting container.
