Definitions
- the invention relates to a stencil device according to the preamble of claim 1.
- Sewing machines are widely used in connection with the automated production of textiles. They serve to automate the actual sewing process and to perform as far as possible without a person who otherwise controls the sewing process manually and possibly leads the fabric.
- the manual activities are usually limited to the insertion of textile blanks in the sewing machines, a triggering of the sewing process, as well as the removal of the sewn textiles.
- stencils are used. These are usually held plate-shaped and have a contour adapted to the respective material, either for handling the material and / or as a default needle path for a needle of the sewing machine.
- a needle path can be introduced in particular in a template a groove.
- the templates also serve, for example, for holding down the material to be sutured or for transferring the material to be sutured from an insertion station of the automatic sewing machine to a sewing station of the automatic sewing machine.
- Such templates are thus designed specifically for each type of sewing material and sewing process. If another sewing material, such as another model of trousers, a shirt or other changes are made with a sewing machine, a new template must be made and replaced previously used on the sewing machine template against the new template. Since the templates each have geometrically complicated and complicated interface means with which the sewing template can be arranged on sewing machine-side interface means and can be detachably fastened, the conversion of a sewing machine from one sewing material model to another
- high cost is also disadvantageous that for the production of complete template devices usually different machine tools are needed.
- most sewing factories usually have neither an extensive machine tool park nor the necessary personnel for the planning and execution of such metal fabrication work.
- the stencil devices are thus usually ordered from the manufacturer of the sewing machine, but this is associated with delivery times, usually of several weeks. A quick conversion from a fabric model to a new fabric model is therefore usually not possible.
- the fast-paced fashion industry however, there is often the need for such rapid and short-term conversions of sewing machines to new models of sewing material and / or different clothing sizes. There is therefore a great need to be able to quickly convert sewing machines with their stencils without this being a viable and cost-effective solution exists.
- the invention is therefore based on the object of specifying a possibility for generic stencil devices, by which result in faster retooling possibilities of stencil devices of the type mentioned in sewing machines.
- first interface means are arranged on a support means of the Nähschablonen issued, wherein the support means is physically separated from the at least one stencil plate, and the at least one stencil plate by means of second interface means solving and replaceable on the support means of the template device can be fastened.
- a further interface is thus introduced in comparison to the prior art, through which the template device itself in two Components is divided.
- the two components of the template device according to the invention can be releasably connected to each other.
- the machine-specific component can meet all requirements with its first interface, so that the required strength and secure connection to the sewing machine can be ensured for the template.
- the machine-specific component can thus be designed exclusively in accordance with these requirements, both constructively, geometrically and with respect to the materials used.
- the machine or sewing machine side component of the template device may also be suitable due to their preferably higher quality embodiment, to be used in succession for different customer or material-specific components.
- the possible preferred choice of one or more higher-grade materials for the machine-specific component of the template device can thus lead to a significantly longer service life of the machine-specific component.
- the machine-specific component - if necessary, together with alternately different custom or material-specific components used until the machine-specific component has reached its end of life can be avoided that parts of previous template devices must be taken early and before reaching their end of life therefore already from the operational use, because after completion of the template device in connection with the corresponding template device clothing item that produces only a smaller number shall be.
- the machine-specific component can also be designed and designed such that it can also record a drive movement transmitted to the template device without play for a transfer movement of the textile blanks to be processed and convert it into a movement of the template device.
- the division according to the invention of the respective template device into a machine-related component and into at least one component-specific or component-specific component makes it possible to form the component-specific or component-specific component alone, or at least above all, according to the requirements of the customer, including the option of a template to create and use as soon as possible.
- the at least one stencil plate of the component-specific or component-specific component can therefore consist of a material that can be processed with simple artisanal means.
- sheet materials may be suitable, which are also editable with saws, jigsaws, files and the like. It may therefore be preferred for the manufacturer of a sewing machine to provide the customer with a complete machine-specific component of a specific template device, including the first interface means, which may already be installed when a sewing machine is delivered or at least can be mounted with little effort.
- the customer of the automatic sewing machine can also be provided with the second interface means for the detachable attachment of the make or paste-specific component of the template device to the machine-specific component thereof.
- the customer can continue, at least one not yet adapted to a fabric or a textile blank stencil plate are provided as a semi-finished product.
- the customer stores a plurality of such semi-finished template plates, which may for example be rectangular or square and have a size which makes it possible by processing the respective stencil plate, the at least one semi-finished stencil plate with a matched to the at least one textile blank contour of the stencil plate Provided.
- this contour may include an inner and an outer contour, for example, an outer contour, which corresponds to the geometric shape of the blank, optionally with an addition or deduction.
- An inner contour may, for example, correspond to a needle path of a needle, which forms one or more seams on the blank.
- This respective semi-finished stencil plate can preferably be provided by the customer himself by means of tools with the respective required contour. Due to the ease of processing, this is possible with little technical effort by the customer.
- a semi-finished stencil plate provided with the corresponding contour and make it and thus adapt it to the now to be produced sewing material or to associated textile blanks. Since the semi-finished template plates are stocked and can be processed with the simplest tools such as metal saws, jigsaws, files, pliers, etc., it is possible for the user to adapt one or more semi-finished template plates to the needs in a very short time and thereby one or more for the production to produce suitable stencil plate. These stencil plates can then be immediately and without waiting for delivery times, mounted on the machine-specific components and used in the sewing machine.
- the semi-finished template plates can consist of simple and inexpensive metallic materials, it is by the invention with significantly lower financial cost than previously possible, with the sewing machine for a specific task to run in the sewing machine tests with several differently shaped stencil plates and for manufacturing then to use the stencil plate most suitably pointing.
- the automated production of clothing and other textiles can be optimized in a simple, fast and yet cost-effective manner.
- the respective machine-specific component having the above-mentioned preferably present properties and configurations has a carrier means.
- the carrier means may be physically separate from the at least one stencil plate and also from the sewing machine, whereby due to the second interface means it is possible to replace the respective at least one stencil plate or other stencil means on the carrier means with at least one other stencil plate / stencil means, without to solve the carrier means with the first interface and optionally further connection means on the sewing machine.
- the one carrier can remain unchanged in the sewing machine when using different template means / stencil plates and alternately one of the Pick up stencil means / stencil plates and thus indirectly connect the stencil means / stencil plate to the automatic sewing machine.
- the carrier means is interchangeable due to the existing first interface means, for example, because the service life of the carrier means is reached or because different second interface means to be used.
- a stencil system according to the invention, in particular a sewing template system.
- This is characterized by the detachable and replaceable attachment of the support means on the automatic sewing machine as well as by the support means again alternately also releasably attachable stencil plates.
- the template plates represent this by a corresponding shape and / or contouring the respective adjustment of the sewing machine to each textile product to be produced.
- Such a template system can be provided in principle for only one, for several or for each station of a sewing machine, the template system the respective needs and requirements of the respective station in the sewing machine can be adapted.
