Description

The present invention relates to a method for applying by means of an embroidery machine at least one substance in a preprogrammed pattern on a stick bottom. Furthermore, the present invention relates to a device for embroidery machines, in particular Schifflistickmaschinen for applying a substance to a stick bottom. The present invention also relates to an embroidery machine comprising a plurality of needle points, in particular a ship's knitting machine or a multi-head embroidery machine, which contains at least one device for applying a substance, in particular a spraying device, preferably a plurality of spraying devices.

STATE OF THE ART

Modern, automatic embroidery machines can be equipped with various additional devices, such as sequin and Soutachevorrichtungen to embroider sequins, cords, cords and the like on a stick bottom. This allows the production of a variety of elaborate embroidery. The embroidery of patterned embroidery floors by large or multi-head embroidery machines could not be realized satisfactorily in practice, however, as an exact positioning of the embroidery base is hardly possible relative to the needle points over its entire width. Here also plays a role, how the floor of the floor in the hoop is stretched. If this is done by hand, a uniform tensioning of a fabric web, which is often several meters wide, can not be achieved with the required accuracy. But even then, when the fabric is unrolled from a roll of a tenter or gate, it comes across the width of the fabric to distortions. The consequence of this is that it is not possible to precisely or oversize fabric samples (printed, dyed or woven). Also, the use of sensors to determine the exact position of the patterns does not help, as fabric distortions can not be easily corrected.

Known devices are eg in the writings GB 303 342 . EP 1496146 A1 and DE 102 39192 A1 to find.

The patent GB 303, 342 discloses an early combination method of creating a floral design wherein a first incomplete part of the design is weaved on a loom and a second incomplete, first part complementary part of the design is applied using another technique, such as a printing technique ,

The patent application EP 1 496 146 A1 shows an apparatus for an automatic method. The device is equipped with a first workstation including a weaving machine and a second trailing workstation including at least one head for embroidering and / or attaching other decorative elements. A fabric which is produced on the weaving machine can, according to this disclosure without cutting, be loaded directly onto an embroidery or other application machine. As a result, weave patterns and successor decoration can be automatically matched.

In the Revelation DE 102 39 192 A1 a device for the subsequent decoration of textile webs is shown. With the device rapportlose, large-scale decoration of textile webs to be realized. Also, the simultaneous or sequential use of different decorating techniques such as combinations of filamentary and other confectioning procedures, should be possible on designated areas of a web. For this purpose, the material to be processed or to be decorated web is stretched laterally and moved in the longitudinal direction by a conveyor. At a distance from the web, at least one processing head is aided, which is moved by means of linear guide according to the predetermined pattern rule on the guided web piece.

It would be desirable if panels could be automatically embroidered and printed or otherwise equipped with a desired substance or mixture of substances. However, the automatic processing results in quality defects due to insufficient overlaying and / or matching of embroidery patterns and printing patterns. When re-clamping the embroidery and / or when moving the Embroidery hoop on a second device or in another working position during the change from the embroidery machine or the embroidery process to the printing press or to the printing process or vice versa often arise reference errors between the embroidery pattern and the print pattern. The deviations from the originally planned design are extremely disturbing in most cases, which can lead to a high rejection or a strong depreciation of the goods.

OBJECT OF THE INVENTION

It is therefore an object of the present invention to provide a method, a device and an embroidery machine of the type mentioned, which are suitable for embroidering and applying in particular color samples, but completely or at least partially avoid the described disadvantages of known devices. It would also be desirable if the embroidery floors could be equipped directly on the embroidery machine with other media, in particular sprayable liquids.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a support 11 of a Schiffli embroidery machine, on which a needle point 17 is arranged. The needle point 17 comprises a back and forth movable needle ram 27, on which a needle can be arranged (in Fig. 1 Not shown). In front of the needle tappet is a throat plate 12 with Stöckli 13 arranged behind it. In Stöckli 13 there is a Schiffli (in Fig. 1 not shown), which can be moved up and down with a driver bar not shown in detail. The components described so far and their function are well known to those skilled in the relevant patent literature, so that they need not be further explained. Before the throat plate 12 is an embroidery bottom resp. Embroidery base 15 spanned in the form of a fabric (dash-dotted lines drawn). The throat plate 12 forms a contact surface for the embroidery base 15. The embroidery base 15 is in a known manner to a gate resp. Embraced hoop, which is preferably computer-controlled in the x and y directions movable.

The coordinate system referred to here is the Cartesian coordinate system with three orthogonal directional axes, here denoted by x, y and z, which intersect at the origin.

According to the invention, this embroidery machine is now equipped with a spray head 19. This spray head 19 is arranged above the needle point 17 on a module carrier 23. The spray head 19 is fastened via a fastening means not shown in more detail on the module carrier 23. The fastening means of the spray head 19 comprises an adjusting device in order to adjust the spray head 19 in the direction of the embroidery base, ie in the z-direction. The adjusting device may comprise a support on which the spray head, e.g. in the manner of a carriage, is arranged displaceably. Advantageously, the attachment means comprise guide means, e.g. in the form of a linear guide element, e.g. a rail on which a carriage is arranged Veschieblich. In this case, the carriage may be the support on which the spray head is arranged. However, it is conceivable to provide guide means directly on the spray head, so that no separate support is needed. By means of suitable locking means, the carriage or the spray head can be fixed to the guide element. Preferably, a co-operating with the carriage threaded spindle is provided in order to determine the position of the spray head relative to a support and thus the embroidery base exactly. The locking of the threaded spindle can be done with a lock nut. However, it can also be provided a motor-driven adjusting device, which can be addressed directly via the machine control. The maintenance of an exact spacing of the opening of the spray nozzle from the embroidery base is important for the control of the bar width of the sprayed liquid medium applied to the embroidery base.

Due to the fixation of the spray head 19 and needle point 17, in particular spray nozzle 33 and needle plunger 27, on the common module carrier 23 or simply on the embroidery machine frame stitching point 29 and 35 spray point in predefined relative position can be selected.

Based on Figures 2-4 a spray device 37 will be described in more detail. The spray device 37 consists at least of a spray head 19 with nozzle 33 and preferably a collecting station 39. Advantageously, a spray head 19 and its associated collecting station 39 are arranged directly opposite each other in front of and behind the embroidery base, in such a way that superfluous by the embroidery base penetrating spray by means of the collecting station 39 can be collected. This is important for a smooth operation of the embroidery machine, since the spray substance urged by the embroidery base would pollute the embroidery machine. In addition, the ambient air would be unduly burdened.

Preferably, a collecting station 39 is provided for each spray head 19 on the side of the embroidery base 15 facing away from the spray head 19. The collecting opening 41 of the collecting station 39 is directed towards the exit of the nozzle 33. The collection opening 41 preferably leads via a funnel-shaped basin part 42 to a narrower end opening 43 into a suction tube (not shown), which is expediently e.g. further flows into a collecting container. A suction air mechanism may be provided which effectively sucks the excess substance collected in the hopper into the receptacle.

As a spray head 19, a signing gun, an automatic spray gun, an airbrush gun, an airless spray gun or a similar device is advantageously used, as it is preferably commercially available.

In FIG. 4 some details of a signing gun 19 are shown. The connecting line 45 serves to supply the material to be sputtered, ie the substance to be sprayed, which is advantageously present as a liquid, but optionally also as a powder. This material, such as paint, varnish or adhesive, is preferably transported from a reservoir, which is under pressure, in the signing gun 19. In addition, spray air is added via connecting line 47 (alternatively, another medium or a mixture of different media could also be used be introduced). The supplied spray air serves to atomize the substance to be applied.

Another connecting line 49 serves to control the injection process. Conveniently, the line 49 is used for control air supply. With the aid of the control air, a valve in the interior of the spray head 19 can activate and deactivate the spray function by at least interrupting the supply of the substance to be applied and / or the atomizing air to the nozzle. Preferably, the direct electrical control of the valve, as shorter switching times are possible.

The outer nozzle needle assembly 51 is connected to a needle which serves to control the passage through the nozzle outlet. In particular, can be reduced or increased by adjusting the nozzle needle, the outlet opening, whereby the amount of the exiting substance can be adjusted.

In addition to a spray head 19, the embroidery machine with other accessories, such. a sequin and / or Soutacheeinheit 21 be equipped. Spray head 19, sequin and / or Soutacheeinheit 21 are preferably mounted in a particular repeat on the module carrier 23.

The inventive spray head 19 may additionally be arranged on a Schiffli or multi-head embroidery machine. A multi-head embroidery machine usually has a plurality of embroidery heads, each of which normally carries a plurality of needle locations and thereby defines a plurality of stitch points 29.

The spraying method by means of the described spraying device 37 will now be described. Here, a substance is sprayed, or sprayed or atomized. The spray device thus serves for spraying or atomizing a substrate. Under the terms atomizing, spraying and Splashing is preferably understood to mean the splitting of liquids into droplets or particles and subsequent or simultaneous distribution thereof.

For application, the substance to be applied is preferably mixed with sprayed air. By mixing and simultaneous or subsequent expansion, the substance to be sprayed is atomized. Such a functioning spray head is also called two-fluid nozzle or pneumatic atomizer.

The above mixing advantageously takes place before the common nozzle outlet of the mixture still within the gun housing in a so-called inner mixing chamber. Spray air and applied substance are passed under pressure into the mixing chamber and mix there under pressure so that the substance is atomized due to the form when the common nozzle exit. The mentioned mixing of gas and liquid medium containing the substance to be applied can alternatively be done outside the nozzle. This is called an outer blend. For this purpose, spray air and substance to be applied are driven approximately in Düsenachsrichtung through the separate nozzle outputs. The two media mix at the exit, causing atomizing substance droplets to form.

Optionally, the two-fluid nozzle described can also be replaced with a single-fluid nozzle. Single-fluid nozzles apply a substance with the help of pressure energy, without interfering with any atomizer gas. In a simple embodiment, the single-substance nozzle essentially has a bore through which the substance to be applied, in this case as a liquid, emerges at a certain speed.

A substance to be applied in a container is preferably pneumatically pressurized (eg by connection to a compressor) and distributed over a material delivery system, ie via a hose line to a spray head or via several hose lines to individual spray heads. Each spray head is controlled via at least one on / off valve. This clears the way to the nozzle opening or closes it. Thus, an on and off of the Spraying possible. The control of this valve is advantageously carried out electromagnetically, because this very short switching times are possible.

In addition, atomizing air is normally introduced into the substrate flow, whereby the substance to be applied (such as a paint) can be finely sprayed on the embroidery base. Compressed air can be used for the atomizing air. This technique allows e.g. To create the finest color gradients, which are the design hardly more limits.

The control commands and optionally various spray parameters are advantageously programmable and integrated into the existing embroidery program.

In the process according to the invention, a spray gun of relatively small dimensions, e.g. a length of 15 cm, preferably 10 cm and correspondingly smaller cross-sectional masses are used. Due to the small dimensions of the spray head 19, on the one hand, a plurality of spray heads 19 can be integrated into an embroidery machine and, on the other hand, the distance from the stitch point 29 to the spray point 35 can be kept as low as possible.

With the spray device described point, line and area markings can be applied depending on whether the embroidery bottom during the injection process undergoes a relative movement to the spray nozzle or not.

Advantageously, several spray devices are mounted in a specific repeat to the needle locations.

If several spray devices are used and / or different substances in several feed tanks, different substances can be applied alternately or simultaneously side by side - e.g. Color changes are possible. The machine control can be carried out via the embroidery machine program.

With the spray, any liquid substance, even with fine pigment depending on the nozzle size, on the embroidery base, ie either the unprocessed or the already partially embroidered embroidery bottom, are applied. The application of particle suspensions is possible, for example, with outside-firing pistols. The spray device includes, for example, a single-component atomizer for applying, for example, a liquid substance or a two-component atomizer for applying a liquid with particles according to the principle of a jet pump, as described above compressed air can be used as a propellant.

In addition, to prevent contamination and increase process reliability, a flushing system can be integrated. Such a flushing system may e.g. Include a connection for a detergent supply for cleaning the nozzle after the last injection.

The spray device of FIGS. 5 and 6 is different from that of FIG. 4 essentially in that two connection points 53a, 53b for storage container 55 are provided. The connection points 53 a, 53 b are equipped with a self-closing valve 57, which closes the opening 59 of a connection point automatically when no reservoir is connected, and the opening 59 releases when a reservoir is attached to the opening 59. In order to enable a rapid change of the storage container 55, containers 55 and connection points 53a, 53b are equipped with a quick-release closure, not shown in detail, for example a bayonet closure.

So that there is no lubricating effect during a color change because there are still substance residues from the previously connected container in the fuel device (memory effect), the interior of the spray device and the lines between the connection points 53a, 53b can be rinsed. For this purpose, a collecting tank 61 is connected to one connection point 53a and an overpressure source 63 or a cleaning solution is connected to the other connection point 53b. Thereafter, the residual substance in the lines can be blown out or washed out and collected in the sump.
