Description

The invention relates to a design device for designing knit products produced on a flat knitting machine in a knitting time-optimized manner, having at least one storage device for receiving the data necessary for producing the knitted product on the flat knitting machine, at least one display device for displaying at least one compressed symbol representation, e.g. a thread running representation, surface representation or color representation, z. B. without Umhängereihen, and a non-compressed symbol representation of the mesh product and with at least one input device for changing at least the compressed symbol representation.

The EP 1 020 554 A2 discloses a designing device of knitted products made on a knitting machine in which as design images at least one stitch image representation and yarn running representation of the knitted product can be displayed and changed by at least one input device, the design means simultaneously changing the other representations when changing one of the representations.

The item by Georges Scolart: "La Stoll M1 au banc d'essai", Filiere Maille, vol. 4, trimestre 2002, no. 66, pages 46 - 51 , describes a knitting machine design device having a graphical user interface that can be used to interactively switch between different views.

In order to achieve the shortest possible production time for a knitted part, it is always attempted to produce as many courses as possible in each carriage stroke. Sleigh strokes with pure transfer operations are avoided as much as possible. In order to be able to produce further courses in knitting strokes, in which a different offset than in the previous carriage stroke must be used, the stitches on a needle bed must be produced prior to knitting in the offset collected and redistributed after moving the needle bed. This is z. B. applied in knitting techniques such as the Abketteln, mitigating and structural patterns, such as. B. a braid. It is a complex technique that only advanced users can master. It is difficult to imagine how the stitches on the machine change position in relation to the offset, especially if this happens more often without the stitch being knit.

For the knitting of a pattern usually courses and Umhängereihen are necessary. The rows of stitches form stitches and the rows of stitches move the stitches to another position (on a different needle). A knitting pattern can be created either in a compressed symbol representation or in an uncompressed symbol representation. In the compressed symbol display, usually only the rows of stitches are displayed. In a following step, the rows of transfers are inserted after a conversion rule. This creates an uncompressed or uncompressed symbol representation. After conversion to the uncompressed icon view, the rows of beds that are offset will display the needle beds offset or untranslated.

Alternatively, it is known to create a knit pattern in an uncompressed symbol representation. The entire pattern is drawn immediately in the uncompressed symbol representation. This means that at the same time the courses and rows of transfers are entered and displayed.

The object of the present invention is to provide a design device which facilitates the design of a pattern and can be generated in a short time with the knitting time-optimized knitting programs of less experienced knitting technicians.

This object is achieved by a design device for designing knitted products produced on a flat knitting machine with at least one storage device for receiving the data necessary for the production of the knitted product on the flat knitting machine, at least one display device for displaying at least one compressed symbol representation, in particular without Umgehereihen, and one not compressed symbol representation of the mesh product and at least one input device for changing at least the compressed symbol representation, wherein at least the compressed symbol representation is convertible into the uncompressed symbol representation according to a conversion rule and the compressed symbol representation considering the conversion rules and without consideration of the conversion rules is displayable and not compressed icon representation is always updated automatically when the compressed symbol representation is changed by means of the input device.

It is possible to switch between the display of the compressed symbol representation with or without consideration of the conversion rule. Furthermore, it is possible to synchronously display and update the compressed symbol representation (eg without displaying the conversion rule) and a non-compressed symbol representation.

It may be contemplated that the compressed icon representation may be converted to the uncompressed icon representation in accordance with at least two different conversion instructions as to how to form stitch courses on staggered needle beds.

This provides a user with additional options on how to display the mesh product displayed in the compressed icon representation after conversion to the uncompressed icon view. This facilitates and accelerates the control of the design of a knit pattern. The conversion rules affect the conversion and can be changed arbitrarily before conversion.

The conversion rule can be set globally for the entire pattern and enabled or disabled for each row, or different conversion rules can be set for each row individually and optionally stored.

According to one embodiment of the invention can be provided that in the uncompressed symbol representation depending on the conversion rule in a Nadelbettenversatz to be performed by the needles knitting operations as not offset or only the needle action of the staggered needle bed as staggered or the needle actions of both needle beds are shown as offset. These conversion rules can be specified globally for the entire pattern or for each course of stitches individually. This provides a user with the ability to define or change conversion rules in the compressed icon view, and view the result in a synchronized, uncompressed view.

Furthermore, it can be provided that the execution of the conversion rule can be displayed in the compressed symbol representation with staggered needle beds. As a result, needle beds and / or needle actions for each needle can already be displayed offset in the compressed symbol representation. The display can always be switched back and forth between the display without offset of the needle beds and with the display of the needle bed offset and thus the conversion rules used.

In each representation variant of the compressed pattern, changes can be made to the pattern.

According to one embodiment it can be provided that the non-compressed symbol representation can also be changed by means of the input device. Thus, even after the conversion, a user can still edit and modify the created mesh product without having to return to the compressed icon representation.

It can be provided that needle actions which are to be shifted in the conversion from the compressed symbol representation to the uncompressed symbol representation are selectable. Furthermore, it can be provided that needle actions of at least one needle bed are displaceable in the compressed symbol representation by an adjustable offset value.

According to an advantageous embodiment of the invention, the direction in which meshes are to be collected can be predetermined in the compressed symbol representation. It can thus be specified in the compressed symbol representation, whether on the front or rear needle bed stitches are to be collected.

Furthermore, a mesh position may be selectable and its position highlighted in the uncompressed symbol representation in each course. This allows a user in the uncompressed icon view to track the position of a stitch from row to row. The position of the stitch in each row can be indicated, for example by highlighting the position of the stitch in color.

Furthermore, it can be provided that each carriage stroke is assigned its own conversion rule.

The advantages of the invention are, in particular, the time savings in the pattern creation. A user can already display the shifted needle actions of a needle in the compressed symbol representation. A conversion to a non-compressed symbol representation is not necessary for this. Furthermore, a pattern may be drawn in an uncompressed symbol representation or only partially in a compressed symbol representation. Without additional operation, the needle beds can be offset with the needles offset by the offset value. The creation of knitting time optimized patterns is possible for every user. A user can create the pattern in the conventional manner and, by additional conversion instructions, obtain a pattern of knitting in each carriage stroke without having to know the knitting technique for doing so.

Further features and advantages of the invention will become apparent from the following detailed description of embodiments of the invention, with reference to the figures of the drawing, which show details essential to the invention, and from the claims. The different

Features can be implemented individually for themselves or for several in any combination in variants of the invention.

The FIG. 1a shows a screen display of a mesh product 100 on a display device of the inventive design means not shown here.

The numeral "0" indicates that the needle bed is in the home position. The designations "L1" indicate that a needle bed is offset by one offset to the left. Likewise, "R1" indicates that a needle bed is offset by one offset to the right. However, the offset indicated in the left-hand column is not apparent in the compressed yarn path representation 10 since this representation is not in the corresponding offset-indicating indicator mode. However, the drawing of a knitted product 100 without depiction of the staggered needle beds represents a facilitated input of a knitted product 100.

In the FIG. 1b Drawing is shown with an offset representation of the needle beds. In the second line from below is at the point 11 z. B. to recognize that the rear needle bed has been offset by an offset of one to the left. The drawing in the representation according to FIG. 1b is more difficult than drawing in the presentation according to FIG. 1a , However, the knitting process can be explained by the illustration according to FIG. 1b better control.

The FIGS. 2a to 2c indicate different ways in which, according to different conversion rules, the formation of courses in staggered needle beds can be represented in the compressed symbol representation.

In the FIG. 2a is shown in the upper part of a compressed symbol representation 20 without displacement of the needle beds. On the back needle bed H, two stitches 1 are shown symbolically. On the front needle bed V, the stitches 2 are shown symbolically. For the rear needle bed H, a knitting is set in the offset with an offset of two to the right. The conversion rule envisages that needle action of the needles will not be displaced upon conversion to the compressed symbol representation, with the offset 30 being displayed on both needle beds. Accordingly, in the lower illustration of the FIG. 2a the rear needle bed H shown with an offset by two to the right. The needle actions for the stitches 1, 2 were not postponed.

In the compressed symbol representation 40 (upper half) of the FIG. 2b For the rear needle bed H, three stitches 3 and four stitches 4 for the front needle bed V are indicated. Again, an offset is provided by two to the right for the rear needle bed. The conversion rule to convert the compressed Symbol representation 40 in the upper half of the FIG. 2b in the compressed symbol representation showing the offset 50 of the lower half of FIG. 2b provides that the needle actions of the staggered needle bed (rear needle bed H) are shifted by the specified offset value. This results in the lower illustration of FIG. 2b where not only the rear needle bed H has been shifted to the right by an offset of two, but also the needle actions have been shifted to the right so that the stitches 3 have also been shifted to the right by an offset of two. The needle actions of the stitches 4 of the front needle bed V, however, have not been shifted. They stayed in their position.

The in the Figure 2c clarified conversion rule provides that when converting the compressed yarn path representation 60 in the compressed yarn guide representation showing the offset 70 needle actions of both needle beds H and V are shifted by the specified offset value. Accordingly, not only the needle actions of the stitches 5 of the back needle bed H were shifted to the right by an offset of two, but also the needle action of the stitch 6 of the front needle bed V was shifted to the right by the offset of two. In addition, the rear needle bed H has been shifted to the right by an offset of two. For a user, it is possible to choose before the conversion of the compressed yarn path representation in the compressed yarn guide representation with representation of the offset freely, according to which conversion rule, ie according to Figure 2a, 2b, or 2c to be converted. The conversion regulations according to Figure 2a, 2b, or 2c are used when displaying a compressed symbol representation with offset or when converting a compressed

Symbol representation applied to an uncompressed symbol representation.

The FIG. 3 shows an uncompressed symbol representation 200, in which not only courses, but also Umhängereihen are shown. In the Umhängereihen stitches are, for example, from the front needle bed V on the rear needle bed H relocated. This is shown for example in the areas 201, 202. Prior to conversion to the uncompressed icon view, the user had the option of choosing which direction stitches to transfer, that is, from the front to the rear needle bed or from the rear needle bed to the front needle bed. Thus, it can already be specified in the compressed symbol representation whether stitches are to be collected on the front or rear needle bed. The collection of the stitches and the subsequent spreading of the stitches are automatically inserted into the pattern by the design means as a result of the selected conversion rule.

The FIG. 4 also shows a representation of an uncompressed symbol representation 300. In the second sequence of transfers from below a stitch was marked with a marker 301. Thus, a user can track how the position of the stitches marked with the marker 301 change over the next rows of turns.

In the FIG. 5a is again shown a non-compressed symbol view 400 without representation of staggered needle beds. The presentation of the FIG. 5a can be converted into a non-compressed symbol display with offset needle beds in accordance with the FIG. 5b being transformed. The representation according to the FIG. 5b is used to control the knitting process, while the presentation in accordance with the FIG. 5a can be easily edited and changed. A user can choose between the representations according to FIG. 5a respectively FIG. 5b Switch back and forth and enter changes in both uncompressed icon representations.
