Description

  The present invention relates to the design of knit products such as gloves.

  The applicant manufactures a knit design device that designs knit products on a computer screen. In the knit design device, the arrangement of stitches and the connection relationship between stitches are displayed on the screen using color codes or the like, and the operator edits the design of the knit product on the screen (Patent Document 1). If the knit product has increased or decreased stitches, the direction of the wales that are the rows of stitches in the length direction changes depending on the position of the increased or decreased stitches. If this is displayed as it is, the wales are bent and displayed, so the wales are displayed straight, and the gap generated by the eyes is displayed in “dart color”. The dart color specifies that there is no stitch, the stitches on both the left and right sides are connected to each other, and whether the right stitch of the dart is brought to the left or the left stitch is brought to the right. Similarly, the display for each type of processing is displayed with a color code or the like at a place where knitting such as turn knitting, turning of a stitch, C knitting in a tubular knitted fabric, or the like is performed.

  A wale may be inserted or deleted during the design. For example, an operator designates a line into which a wale is to be inserted, and a designated number of wales are inserted into the designated line. Here, if an insertion line is designated so as to pass through an area to which a dart color or the like is assigned, the design of the knit product is destroyed. As a wal to be inserted, it is natural to copy the wales around the insertion line, but when a wal with a dart color assigned is copied, a smaller number of wales than the operator's intention are inserted. In addition, if a stitch for which turnback knitting, turning knitting, C knitting, or the like is inadvertently copied, the design will be destroyed. Therefore, it is necessary to carefully check the position where the wale is inserted. Such a problem is not limited to the insertion of the wale, but the same applies to the deletion of the wale, and the same applies to the case where a course that is a row of stitches in the knitting width direction is inserted or deleted. Further, in the case of a tubular knit product, if processing such as insertion / deletion of wales is performed on one side of the product, it is necessary to similarly perform insertion / deletion of wales at corresponding portions on the opposite side. It is troublesome to find a position suitable for insertion and deletion of wales on each side of the knitted product.

Patent 2916990

  An object of the present invention is to facilitate the editing of the design of the knit product by automatically determining the position to insert and delete the design so that the design of the knit product does not collapse when the wale is inserted and deleted.

The present invention provides an input means for an operator to input a design of a knit product, an input processing unit for converting data input by the operator into design data of a knit product, a memory of design data, and design data A knit design device comprising a color monitor for displaying the arrangement and connection relationship of stitches,
In the design data, data representing at least one of turn back knitting, turning of stitches, darts (position where there is no stitch with a reduced eye), increasing stitches, and C knitting as functional data,
When insertion and deletion of stitch wales and courses are input from the input means, a detection means for detecting whether or not functionality data is included in the input range is provided,
The input processing unit shifts the position where insertion and deletion are performed so as not to include the functional data when the functional data is included in the input range.

In the present invention, when the operator inputs the design of the knit product, it is received by the input means, converted into the design data of the knit product by the input processing unit, the design data is stored in the memory, and the design data is connected to the stitch arrangement. A knit design method for displaying on a color monitor as a relationship,
In the design data, data representing at least one of turn back knitting, turning of stitches, darts (position where there is no stitch with a reduced eye), increasing stitches, and C knitting as functional data,
A step of detecting whether or not functionality data is included in the input range when insertion and deletion of stitch wales and courses are input from the input unit;
When the functional data is included in the input range, the step of shifting the position for insertion and deletion so as not to include the functional data by the input processing unit is executed.

  In this invention, it is detected by the detection means whether or not the functional data is included in the input range, and when it is included, the position for insertion and deletion is shifted by the input processing unit. For this reason, the structure of the knitted fabric is not destroyed by the insertion and deletion of the wale and the course, and the operator can easily input the insertion and deletion of the wale and the course.

  Preferably, when the knit product to be designed includes front and rear knitted fabrics, when the operator inputs insertion and deletion of wales and courses on one of the front and rear knitted fabrics, the front and rear knitted fabrics face each other. Detecting whether the second input range includes functionality data in the second input range at the position, and detecting whether or not functional data is included in the second input range by assuming that the insertion and deletion of wales and courses are input. When the functional data is included in the second input range, the processing unit shifts the position for insertion and deletion so as not to include the functional data. In this way, when insertion and deletion are input to one of the front and rear knitted fabrics, insertion and deletion can be performed at the opposite positions of the other front and rear knitted fabrics. In addition, the insertion and deletion positions can be shifted so as to avoid the functional data in the other knitted fabric before and after.

  Preferably, the input processing unit directly inputs an insertion and deletion position to the display of the stitch arrangement and connection relation displayed on the color monitor, and designates a part in the knit product. It is possible to freely input by. This increases the degree of freedom of input, and when it is important to insert and delete at a specific position, the position can be directly input. In addition, when it is important to insert and delete at a designated part, it is possible to insert and delete by selecting an appropriate position by the detection means and the input processing unit by designating the part. Furthermore, if the operator can specify whether to insert and delete at the center of the part or whether to insert and delete at the end of the part, insertion and deletion are performed at the center avoiding the end where functional data tends to concentrate. Alternatively, it is possible to select whether to insert and delete at the end while avoiding the center where the pattern of the knitted fabric tends to concentrate.

  Preferably, when the position for insertion and deletion is input by designating the part, the input processing unit changes the position for insertion and deletion of the design data in which the wales and courses of the stitch are inserted and deleted. Are displayed on the color monitor, and the design data is overwritten based on the insertion and deletion positions selected by the operator. If it does in this way, a suitable position can be selected as a position which inserts and deletes.

Preferably, in the specification of insertion position of the wales, can specify whether to copy the wales of right or left side of the insertion position, wherein the input processing unit, the wales to be copied reaches to the outer shape line of the knitted fabric, the direction of copying If the functional data is included in the range of the wal to be copied , the wal is copied so as to pass the functional data. In this way, even when the copy range is specified so as to exceed the outer shape line of the knitted fabric, copying can be performed without causing an error. Even when there is functional data within the specified copy range, copying can be performed so as not to overlap with the functional data.

  In the following, an optimum embodiment for carrying out the invention will be shown. The scope of the present invention should be construed in consideration of the possibility of modification by well-known techniques in the description of the scope of claims.

  1 to 5 show an embodiment. In each figure, 2 is a knit design device, a design device for short. The design device 2 is composed of a computer, 4 is a bus, 6 is a color monitor, and 8 is a color printer. 10 is a network interface, 12 is an external memory drive, 14 is a keyboard, 16 is a pen, and may be a mouse, joystick, trackball or the like. The operator inputs the design of the knit product from the network interface 10 to the pen 16, displays an image representing the input design data, that is, the design image on the color monitor 6, and receives the design data from the network interface 10 and the external memory drive 12. Output.

Reference numeral 18 denotes a CPU, and 20 denotes an input processing unit, which converts an operator's input into design data for the knit product. The input processing unit 20 converts the design data into, for example, color code, yarn connection data indicating the connection relation of the yarn and the type of stitch, and stores the data in the memory 26. Color code display design data, hereinafter color code data, for example, represents the outer shape of a knitted product by the number of eyes in the course direction and the wale direction. Functional data is data representing turn knitting, turning of stitches, darts (a position without stitches associated with a reduction stitch), increasing stitches, and C knitting . In addition to this, the color code data may include data such as the type of stitches such as front and back stitches, and the assignment (color arrangement) of yarn carriers. The data of the color code includes at least functional arrangement data such as the arrangement and connection relation of the stitches, and darts, extra stitches, and back knitting, thereby identifying the shape and structure of the knitted product. The color code data is stored in the memory 26 as image data, for example.

  Attached to the input processing unit 20 is a functional data detection unit 22 and a preview processing unit 24. The functional data detection unit 22 detects functional data in the design data, and the preview processing unit follows the operator's input. A preview image of the design data of the edited knit product is created and displayed on the color monitor 6. A conversion unit 28 converts design data into knitting data of a knitted product.

  An example of functional data will be described. In order to adjust the three-dimensional shape of the knit product, turn-back knitting may be performed, and a specific color code is assigned as functional data to a place where turn-back knitting is performed. When the number of wales decreases due to a reduction eye or the like, a specific color code is assigned as the functional data with the reduced wales as “dart”. The color code of “Dart” represents data indicating that there is no stitch and whether the right side of the dart is moved to the left or vice versa. In the embodiment, a glove design which is a tubular knit product is taken as an example, and the glove may be provided with a slit by C knitting on the wrist. A color code which means that the knitted fabric is cut is assigned to the portion of C knitting, not a tubular knitting. In addition, a color code for functional data may be provided.

  In the process of inputting the design data of the knit product and then editing the design data, the operator may insert or delete the wale and insert or delete the course. In the following, the insertion and deletion of wales will be described, but the insertion and deletion of courses can be processed in the same manner.

  As in step 1 of FIG. 2, a line or a deletion range in which a wal is inserted is specified. In the case of insertion, the number of wales to be inserted is also specified, and which wales are to be copied. The insertion is to paste the copied wales on the insertion line between the wales. Deletion is to delete a specified range of wales or courses on one or both sides of the deletion line and connect both sides of the deleted range at the position of the deletion line. Instructions regarding the insertion and deletion of wales may be directly input to the color code screen of design data by designating the insertion line and the range of wales to be copied or the range of wales to be deleted with a pen or the like. Alternatively, a part such as a middle finger or a ring finger may be designated, and the position within the part may be determined by the input processing unit 20 so as not to include the functionality data. This input is called “part designation input”, and even if the part and position within the part are designated in detail, only the part is designated and the position within the part is selected at the next preview image stage. May be. In the part designation input, the number of wales to be inserted or deleted is numerically input such as “3 wales”. In the case of deleting a wal, even if the range of the wal to be deleted is directly input with a pen or the like, it is specified by specifying a part such as “3 wales in the middle of the middle finger” or “2 wales at the left end of the middle finger” May be.

  Most knitted products such as gloves, sweaters, socks, etc. are composed of front and rear knitted fabrics. When the insertion or deletion of a wale or a course is input to one of the front and rear knitted fabrics, the input processing unit 20 It is assumed that insertion / deletion is also input to the opposite position of the other knitted fabric. Since it is possible to input insertion and deletion by looking at only one design screen without looking at both the design screen of the front knitted fabric and the design screen of the back knitted fabric, it is easy to input the insertion and deletion.

  In step 2 of FIG. 2, functional data related to the insertion line or deletion line, that is, data related to the structure of the knit product is detected. When it is detected that the functional data exists on both sides of the insertion line or the deletion line, the insertion line or the deletion line is arranged in the course direction (knitting product editing) so that the functional data exists only on one side of the insertion line or the deletion line. Shift along the width direction. Even when a position without a stitch such as a finger is designated as the insertion line or the deletion line, the insertion line or the deletion line is shifted as in the functional data. For example, even when the wale insertion line or the deletion line overlaps the part of the knitted product that protrudes from the outer shape of the knit product, is included in the dart, the part where the stitches are turned around, the part where the C knitting is performed, Shift the deletion line.

  When a stitch to which functional data is assigned is included in the copy range or the deletion range when inserting or deleting a wale, the stitch of the next wale is copied or deleted so that the stitch is skipped and passed. When the insertion range and the deletion range reach the outer shape line of the knitted fabric, the copying or deleting direction is reversed, and the remaining wales are copied or deleted (step 3). Next, in the case of site designation, a plurality of images (design images with color codes) edited with design data according to the operator's input are displayed on the color monitor 6 as preview images with different positions to be copied and deleted. For example, when the middle finger is designated as the wale insertion position, an image inserted at the center of the middle finger, an image inserted at the left end, and an image inserted at the right end are displayed (step 4). When the operator selects an appropriate image from the display image (step 5), the design data in the memory 26 is overwritten with the knitting data corresponding to the image selected by the operator (step 6). By allowing the operator to select an insertion / deletion position, the insertion / deletion position can be determined so as to avoid a pattern or the like.

  Further, when the insertion and deletion of the wale and the course are input to one of the front and rear knitted fabrics, Steps 2 to 6 are similarly executed for the other knitted fabric of the front and rear. If the insertion / deletion position on one knitted fabric is shifted in the process of avoiding the functional data, it is not necessary to shift the insertion / deletion position on the other knitted fabric.

  3 and 4 show a plain glove design, where the glove has a three-dimensional shape. 30 is a design image of the back of the glove, and 50 is a design image of the palm of the glove, both of which are represented by a color code. Reference numeral 32 denotes a reverse knitting cord, which indicates that a stitch is not formed at the position of the cord 32 after knitting the first course of the fingertip (which is always displayed and is not displayed in the design image). A reduction eye is made at the base of the finger, but it is known which wales of the finger have been reduced, and a dart code is assigned to the reduced wales so that the wales are displayed as straight lines. 34 is a right-justified dart code based on the figure, and 36 is a left-justified dart code based on the figure.

  In order to make the gloves three-dimensional, a right-padded dart cord 44 and a left-padded dart cord 46 are assigned to the base of the thumb and index finger of the palm. Further, a C-knitted cord 42 having a second stitch width is assigned to the wrist side, and the left and right knitted fabrics are separated by the center line of the cord 42.

  The above codes 32 to 46 are examples of functional data. When the portion to which the codes 32 to 46 are assigned is changed, the knitting structure for realizing the outer shape of the glove changes. Design. Therefore, when inserting a wale, the copy range is shifted so that the insertion line does not overlap with the area to which the special code is assigned, and the copy range is shifted so that the stitch range to which the special code is assigned is not included. In the case of deletion, the deletion range is shifted so that the deletion range does not include stitches to which special codes are assigned.

  FIG. 5 shows an example of correcting a wale insertion line or the like. Reference numeral 52 denotes an initial insertion line which is directly input by the operator, and overlaps an area to which the dart code 34 is assigned. If the insertion range of 3 wales is designated on the right side of the insertion line 52, this range extends to a portion without a knitted fabric between the fingers. Therefore, the insertion line 52 is shifted to the right side, for example, at a position where it overlaps the dart 34 to form an insertion line 54. Next, if the 3 wales on the right side from the insertion line 54 are set as the copy range, the finger bag portion has only 2 wales on the right side of the insertion line. Therefore, the 2 wales on the right side of the insertion line 54 are added to the insertion range 56, and the third wales exceed the outline line of the finger. Add to. When inserting and deleting a course, it is preferable to determine an insertion line, a copy range, and a deletion range so as to avoid a course having functional data. When searching for the wale insertion line 56 in the vicinity of the fingertip, the turn knitting cord 32 is present, so if the turn knitting cord 32 is passed, the outer shape line of the finger is exceeded. Therefore, the direction for searching the insertion range is reversed.

  In the examples, a plain glove was shown, but when a tissue pattern, intarsia pattern, jacquard pattern, etc. are added, so as to avoid a range where the tissue pattern, intarsia pattern, and jacquard pattern are added, It is preferable to determine an insertion line, a copy range, and a deletion range. In this case, if insertion and deletion are performed on the end side of the part, there is little interference with a handle such as a tissue handle. In the embodiment, the design data is displayed by a color code. However, if the screen displaying the arrangement and connection relation of stitches is displayed by a method other than color coding, and functional data such as darts, extra stitches, turn back knitting, turning of stitches, C knitting, etc. is detected, it is inserted. By shifting the line, the copy range, and the deletion range, the embodiment can be applied to displays other than color codes.

In the embodiment, the design device edits the insertion and deletion of the wales input by the operator so as to avoid darts, additional stitches, knitting of the stitches, C knitting, turn knitting, etc. And the design of the knitted product is not destroyed.
