DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a knit design system and method of preparing knitting data thereof, wherein control data for instructing a knitting machine is created, and the state of a finished fabric can be learned by a display.
BACKGROUND ART
Heretofore, when a desired fabric is to be knitted by a knitting machine which is disclosed in U.S. Pat. Nos. 4,608,642 or 4,768,357, for example, an operator must set control data instructing contents for driving a knitting machine mechanism such as knitting needles to be used, moving directions and distances of the needles, and the like, as knitting information.
However, in the knitting machine taught by U.S. Pat. No. 4,768,357, test knitting must be carried out by the machine to determine whether or not the set control data is correct or the desired knit state is achieved. For this reason, test knitting and correction of the set control data must be conducted a plurality of times before entering into mass-production. Thus, tedious work is required to set the final control data for the knitting machine.
A recording device of pattern information described in U.S. Pat. No. 4,608,642 displays stitches on a display screen, wherein the information instructing the knitting operation is inputted in the form of color codes. After that, the recording device prepares control procedure data for the knitting machine according to the color codes inputted. The recording device in U.S. Pat. No. 4,608,642, however, poses a problem in that it requires greater operator skill for setting the control data as the stitch structure becomes complicated.
DISCLOSURE OF THE INVENTION
A first object of the present invention is to provide a knit design system which can reduce the repetition frequency of the test knitting, and enables the operator to learn the state of a finished fabric before actually knitting on the machine.
A second object of the present invention is to provide a knit design system and method for preparing knitting data for the same, which can readily prepare control data to be set to the knitting machine.
According to a first aspect of the present invention, there is provided a knit design system comprising: input means for inputting design information that indicates a shape of a fabric to be knitted and a stitch structure; first storage means for storing first calculation information indicating correspondence between the design information and operation information indicating a content of a knitting operation of a knitting machine; and first calculation processing means for converting the design information inputted from the input means to the operation information on the basis of the first calculation information in the first storage means.
According to a second aspect of the present invention there is provided a knit design system comprising in addition to the first aspect of the present invention: second storage means for storing for each type of knitting machines second calculation information indicating a correspondence between the operation information and control information for driving the knitting machine; designation means for designating a type of the knitting machine; and second calculation means for converting operation information which has been converted by the first calculation means into the control information corresponding to the designated machine type on the basis of the second calculation information in the second storage means corresponding to the designated machine type.
According to a third aspect of the present invention there is provided a knit design system comprising: retaining means for storing and retaining the design information inputted, the operation information prepared, and the control information prepared, in the second aspect of the present invention; and correction means for correcting information stored in the retaining means, wherein the correction means can serve the information corrected to the first calculation means when the information corrected is the design information, and can serve the information
