Design device for designing knitwear

technical field

The invention relates to a pattern design device for the design of knitwear produced on a knitting machine, equipped with: at least one storage device for storing data required for the production of knitwear on the knitting machine; at least one display device , for displaying at least one knitting loop diagram and a yarn movement diagram of a knitted product; and at least one input device for changing at least one knitting diagram and a yarn movement diagram, according to which the design device also has: a combination A device for grouping the symbols of the yarn motion diagram of a piece of knitwear into modules; a combination device for grouping the loops of the knitting diagram of a piece of knitwear into modules; and a storage device for storing the above-mentioned Module; also has means for knitting technically correct knitting of said module for inserting the knitting loop pattern and/or the yarn movement pattern of the knitwear.

Background technique

This design device is for example once disclosed among EP 1020 554 A2. The feature of this design device is that the device can automatically calculate and provide relevant control parameters for the knitting machine according to the knitting loop diagram and/or yarn movement diagram of a knitwear. With this design device, coil groups can also be assembled into so-called modules and stored. These modules can then be used in any position in combination with the newly manufactured knitwear or even later designed knitwear. The pattern design device now automatically calculates the knitting-technically correct modules to weave into the base knitted fabric. In this way, for example, the texture pattern can be stored as a module and can be arranged in any position and in any size in a knitted product. At this point, the user of the device does not need to be concerned about the weaving of the modules into the knitted fabric of the base fabric. up. The design device does this for the user. In any case a weaving algorithm has to be devised, which can also be woven by machines.

Of course, in some cases it may be desirable for an experienced user to change the weaving algorithm dictated by the design device. This can be achieved, for example, according to the knitting time or according to a minimum yarn load.

Contents of the invention

The object of the invention is therefore to improve the configuration device mentioned at the outset in such a way that the weaving of the modules into the base fabric prescribed by the configuration device can be changed with this device.

The above-mentioned tasks are solved by a design device for designing knitted goods produced on a knitting machine, which design device is equipped with: at least one storage device for holding data required for producing knitted goods on a knitting machine; at least A display device for displaying at least one knitting loop diagram (Maschenbilddarstellung) and a yarn movement diagram (Fadenlaufdarstellung) of the knitted product; and at least one input device for changing at least one knitting diagram and yarn movement diagram, The design device also has: a device for combining the symbol groups of the yarn motion diagram of a piece of knitwear into modules; a device for combining the loop groups of the loop forming diagram of a piece of knitwear into modules; and for storing storage device for the aforementioned modules; also having means for knitting technically correct weaving of the aforementioned modules when introduced into the knitting loop diagram and/or the yarn movement diagram of the knitwear, the design device is characterized in that it has An interactive device for influencing a knitting-technically correct module insertion via the at least one input device.

With this interactive means, it is now possible for an experienced user to edit and change the weaving algorithms generated by the design means for one or more modules. The user can manipulate the yarn movement map here. In this way, a reduction in knitting time can be achieved, for example, by combining different knitting rows. In order to protect the yarn, for example, the traversing movement of the needle bed can be divided into a larger number of smaller traversing movements over a larger number of needles.

The following approach has particular advantages: by means of mutual interaction, the knitting technology of the desired influence can be influenced in the process of weaving the module into the knitted product correctly in the knitting technology proposed by the device. Feasibility check. A real-time control can then be achieved when editing the proposal of the design device, which can significantly reduce the total design time of the knitwear. Confirmation of the feasibility of the optimization performed by the weaving algorithm can only be expected when the planning device generates control data for the knitting machine for producing the entire knitwear after completion of the design and, if necessary, an error signal.

Further advantages can also be obtained if the interactive means can provide an algorithm for weaving into the knitwear of a plurality of modules arranged next to each other or one behind the other. In this way, changes to the prescribed weaving algorithms for frequently repeated module combinations, for example for Aran-knit patterns and braid patterns, can be simplified.

Furthermore, the memory device is advantageously also provided for storing the frequently required algorithm for weaving the modules into the knitwear given by the interactive device. Certain knitting pattern modules often appear repeatedly on different parts of a knitwear, such as on the torso and back of the garment. A weaving algorithm entered once can then be recalled and applied for all other modules or combinations of modules. This further reduces design time for knitwear.

A particular advantage can also be achieved if the stored weaving algorithm can also be called up for weaving the modules into other knitwear. Therefore, the resulting weaving-in algorithm can be used not only for the newly processed knitwear, but also for other knitwear designs.

The change of the weaving algorithm, which can be carried out by means of interaction, can in principle include all weaving steps. In particular, by means of interaction, the sequence of stitch transfer processes, needle bed displacement movements, etc. proposed by the design device can be changed for weaving modules into knitwear. This permits a change in the slide movement, the use of the individual knitting systems and the thread guides.

In addition, additional knitting rows can also be determined using interactive means. These additional knitting rows can also lead especially to unloading of the yarn.

Furthermore, the design device also has all the features of the design device disclosed in EP 1020 554 A2 at the same time. Especially on the design device proposed by the present invention, the knitting loop diagram and the yarn movement diagram of a knitwear can be displayed and changed simultaneously. Accordingly, several knitwear parts can also be displayed simultaneously on the display device. In terms of knitting loop diagrams, it may be desirable to include a near-realistic, three-dimensional diagram of all elements of a piece of knitwear such as loops, tucks and float weaves. Further improvements in knitting loop diagrams can be achieved by configuring the computing means and loop form display means to calculate and reflect the loop shape from the pattern, size and shape of adjacent loops and from the properties of the knitting yarn used. Here, the following settings can also be made: use the at least one input device to input and change the style, shape and size of the loops in the loop diagram for each needle position of the knitwear.

Yarn motion diagram preferably with various symbols for all elements of knitwear such as loops, tucks, floats, as well as for needles and needle activities of a knitting machine such as weaving, non-knitting, giving, receiving , get rid of, etc.; and preferably have symbols for various parameters of the knitting machine such as yarn feeder movement and slide movement, cloth guide, needle bed displacement and so on.

Furthermore, means can also be provided for determining the boundary module between the loop formation diagram or the yarn movement diagram of a knitting module and the stitch formation diagram or the yarn movement diagram of a knitted article. There may also be means for multiplying and/or mirroring and/or magnifying the modules on at least one display device. There may also be a pattern generator for designing the connection structure of the pattern front and the pattern reverse of a knitwear.

The invention also relates to a knitting machine equipped with the design device proposed by the invention.

On a module side M it is shown that a total of eight knitting systems S1 to S8 need to be implemented in order to correctly weave the modules 2 and 3 into the base fabric 1. The knitting system S1 forms the stitches required for the two modules 2 , 3 . Subsequently, knitting system S2 performs the transfer operation for the two modules 2, 3, then knitting systems S3 and S4 perform the transfer operation for module 2, after which knitting systems S5 to S8 perform the transfer operation for module 3.

FIG. 3 shows a diagram corresponding to circle 2 of a weaving algorithm for modules 2 and 3 which is generated by the user starting from the weaving algorithm shown in FIG. 2 . The operations performed by knitting systems S3 and S4 according to the weaving algorithm shown in FIG. 2 are now performed by knitting systems S7 and S8.
