Description

The invention relates to a design device for designing knitted products produced by a knitting machine having at least one storage device for receiving the data necessary for producing the knitted product on the knitting machine, at least one display device for displaying at least one stitch image representation and a threadline representation of the knitted article and at least one input device for modifying the at least one mesh image representation and threadline representation, the design device further comprising means for combining groups of symbols of a threadline representation of a mesh product into modules and means for combining mesh groups of a mesh image representation of a mesh product into modules and memory means for storing those modules, and Facilities for the correct mesh integration of modules when inserted into the M Ashes display and / or thread running representation of a mesh product has.

Such a design device is for example from the EP 1 020 554 A2 already known. This design device is characterized by the fact that it automatically calculates and indicates the associated control data for the knitting or knitting machine on the basis of a stitched image representation and / or a threadline representation of a knitted product. Furthermore, with this design device mesh groups can be combined to form so-called modules and be stored. These modules can then be used at any point of the mesh product being processed or even a later designed mesh product. The design device automatically calculates the mesh-technically correct integration of the modules into the basic fabric. In this way, for example, cable patterns can be stored as modules and placed anywhere and in any size in a mesh product, the user does not have to worry about integrating the modules in the basic knit. This is done by the design facility for him. In any case, integration algorithms are generated which are also knit by the machine.

However, in some cases it is desirable for skilled users to change the integration algorithms given by the designer. This can be done for example with regard to the knitting time or with respect to a minimum yarn load.

From the DE 43 29 875 A1 is a design device with a fitting unit that checks this design for knit incompatibilities upon completion of the entire knit design by the user. The fitting unit shows the user all knitting intolerances in succession and submits a correction suggestion for each position, which the user can accept or change manually. However, real-time control of manually made changes is not possible. Also, the changes can not be defined as a rule that can be applied to other parts of the same or even another piece of fabric.

DE 4329875 A1 discloses a design device according to the preamble of claim 1.

The present invention is based on the object to further develop the aforementioned design means that with her a change in the predetermined by the design facility integration of modules in a basic knitting is possible and these changes can be defined as rules.

The object is achieved with a design device having the features of claim 1.

With the interactive facility, it is now possible for an accomplished user to edit and modify the integration algorithm generated by the designer for one or more modules. He can use the thread running representation. Thus, for example, by combining different knitting rows can achieve a reduction of the knitting time. To protect the yarn, for example, offset movements of the needle beds over several needles can be divided into several smaller offset movements.

It is particularly advantageous that a review of the knitting technical feasibility of the desired influence is feasible by the interactive device while influencing the proposed by the device mesh correct correct integration of modules in the mesh product. It is thus a real-time control during the editing of the proposal of the design facility possible, which can significantly shorten the overall design time of the mesh product. It is not necessary to wait for the feasibility of the optimization of the integration algorithm to be carried out until the design facility, upon completion of the design, generates the control data for the production of the entire knitted product for the knitting or knitting machine, possibly issuing an error message.

Further advantages result if algorithms for integrating a plurality of modules arranged next to one another or one behind the other into the mesh product can be specified with the interactive device. This simplifies the modification of the given integration algorithms for frequently recurring module combinations such as the juxtaposition of an Aran pattern and a Zopfmusters.

There are also storage means for storing commonly required integration algorithms of Modules provided in the mesh product. Certain knit pattern modules often repeat at various points in a knit product, such as the body and back of a garment. Once the integration algorithm has been entered, it can then be recalled and used for all other modules or module combinations. This also makes it possible to further reduce the design time for the mesh product.

Particular advantages arise when the stored integration algorithms for integrating modules can also be called into other mesh products. The generated integration algorithm is then applicable not only to the mesh product being processed, but also to other designs of mesh products.

The change in the integration algorithm that can be carried out by the interactive device can in principle include all steps of the integration. In particular, by means of the interactive device, the sequence of transfer operations, needle bed offset movements, etc. proposed by the design device for modifying the mesh product can be changed. As a result, the carriage movements, the use of the individual knitting systems and the thread guide can be changed.

In addition, additional knitting rows can be definable with the interactive device. Such additional knitting rows can lead in particular to the relief of the yarn.

Furthermore, the design means all in the known design device according to the EP 1 020 554 A2 existing features also have. In particular, in the design device according to the invention, the stitch pattern representation and the yarn running representation of a knitted product can be simultaneously displayed and simultaneously changed. It can also several Sections of the mesh product can be displayed simultaneously on the display device. The mesh image representation may preferably include a close-to-reality, three-dimensional representation of all the elements of a mesh product such as mesh, catch and float. A further improvement of the mesh image representation can be achieved if means for calculating and imaging the mesh shape are provided depending on the type, size and shape of the adjacent meshes and depending on the properties of the knitting yarns used. It can also be provided that with the at least one input device for each needle position of the mesh product, the type, shape and size of the mesh in the mesh image representation are entered and changed.

The yarn guide may preferably have symbols for all elements of the knitted product such as knitting, catching, floats and the needles of the knitting or knitting machine and their activities such as knitting, non-knitting, transfer, take over, throwing off, etc. and preferably symbols for parameters of the knitting or Knitting machine such as yarn guide and carriage movements, fabric removal, needle bed offset etc.

Further, means may be provided for defining boundary modules between the stitch pattern or threadline representation of a knitting module and the stitch pattern or threadline representation of a stitch product. It may also have means for replicating and / or mirroring and / or enlarging modules on the at least one display device. Also, it may have a jacquard generator for designing the jacquard visible side connection structure with the jacquard back of a mesh product.

The invention also relates to a knitting machine having a design device according to the invention.

Fig. 1 shows a screen display of a mesh product 100 on the display device of the inventive design means not shown here. The knitted product 100 has a basic knit 1 into which two knitting modules 2 and 3 have been inserted by a user. The basic knit is a plain-right knit with all needles. With the knitting module 2 an Aran pattern strand was formed. This is composed of a plurality of modules 2, wherein the individual modules 2 are arranged as Aran pattern fields 21 to 29 one above the other and each offset by one needle to the right. From the module 3 three cable patterns 31 to 33 have arisen, which are arranged one above the other.

In Fig. 2 the incorporation algorithm for modules 2 and 3 automatically created by the design facility is shown. Above a module strip M is shown one above the other, what the total of eight knitting systems S1 to S8 have to carry out in order to correctly integrate the modules 2 and 3 into the basic knit 1. The knitting system S1 forms stitches for the two modules 2, 3. Subsequently leads the knitting system S2 performs capping operations for both modules 2, 3 before the knitting systems S3 and S4 perform capping operations for the module 2 and thereafter the knitting systems S5 through S8 perform capping operations for the module 3.

Fig. 3 shows one of the Fig. 2 corresponding representation of an integration algorithm for the modules 2 and 3, which by a user, starting from the in Fig. 2 The integration algorithm shown was created. The operations performed after the merge algorithm Fig. 2 performed by the knitting systems S3 and S4 are now executed by the systems S7 and S8. The functions of the systems S5 to S8 of the algorithm Fig. 2 get in the algorithm Fig. 3 taken from the systems S3 to S6. The user can do the necessary shifting of the lines of the screen display Fig. 2 using the interactive setup of the design facility. During the move, the interactive device checks whether or not the currently reached position of the shifted line is knit-technically feasible. Non-knit positions are identified, for example, by a corresponding color marking.

Using the in Fig. 3 the integration algorithm for the modules 2, 3 shown, the design device then generates the in Fig. 4 shown knitting process, which is also displayed on the display device of the design device.

The in Fig. 3 described, by a user interactively generated with the design device integration algorithm can be stored and is thus available to call at any other point of the mesh product 100, to which also the modules 2, 3 are to be integrated, available. The incorporation algorithm may also be used in the design of new mesh products which are also to be provided with the modules 2, 3.
