The key is kept selected until another key is selected again. When the user selects the mistake key 39 and clicks the needle on which the loop is already displayed, the displayed loop is deleted. As described above, when the needle that has already locked the loop is designated as a mistake, the loop is erased. In the present embodiment, this is expressed as displaying the missed loop. Conversely, if a needle in a missed state is designated as a knit or tack, a new knit or tack loop is displayed for the needle whose loop was not locked.

Numeral 41 designates racking designating means for moving the rear needle bed relative to the front needle bed in the longitudinal direction. The racking designation means 41 is displayed on the design data input screen by left and right keys 43 and 45 provided in each block. By pressing any key, the rear needle bed is racked at a pitch of 0.5 needles in its longitudinal direction. Key 4

In addition, if an enlargement / reduction function is provided together with the scroll function, and the design data is input by combining the two functions, the input operation can be performed more efficiently.

Next, referring to FIGS. 3 to 6 and FIG.
A method of creating design data using the design apparatus according to the present embodiment will be described, taking as an example the case of forming a second rope pattern. 5 and 6 are flowcharts, and FIG. 8 shows a simulation image of a knitted fabric knitted based on the design data shown in FIGS. (However, for the sake of simplicity, in the design data shown in FIGS. 3 and 4, only the knitting of portions (indicated by X) related to the formation of intersections is shown). As shown in block 1 in FIG. 3, a fourth eye in which two eyes in the center are crossed to form a rope pattern, a second eye in the outer side, and The design data for forming a knitting structure composed of the three stitches formed on the outside thereof is created.

A method of inputting design data from S1 at which input of design data in FIG. 5 is started will be described. If the gauge value and / or loop length of the flat knitting machine used in knitting on the actual machine is determined, the gauge value or loop length is input in S3 and S5. If the gauge value or the loop length used in knitting in the actual machine is unknown, S2 and S4 are skipped and the process proceeds to S6. In S6, the block number is set to 0 block, and in S7, 1 block is added to the 0 block which is the block number of the previous block set in S6 to make the current block number 1 block, and the block number 1 is highlighted and displayed. The blocks where the current design data can be entered are displayed. Next, in S8, it is specified whether the block 1 for inputting design data is a knit course or a transfer course. In the present embodiment, a knit course is selected to input the design data shown in block 1 of FIG. When the knit course is selected, no special operation is required because the knit course is set by default. Subsequently, in S9, setting of a meeting is performed. In the design device of the present embodiment, the rib setting where the front and rear needle beds are in a state where the phases are different by 0.5 needles is set as a default as in the actual device. The bed is racked by 0.5 needles with respect to the front bed so that both sides meet.

Next, in step S10, the type of loop to be input (loop type) is selected. In block 1, a knit key is selected. In step S11, the stylus pen sequentially clicks the needle 121 of the front needle bed and the needle 123 of the rear needle bed which form a loop in the block 1, and the clicked needles 121 and 12 are clicked.
3 are formed by yellow knitting yarn indicating the knit course, and the formed loops 125 are connected by the jumping yarn 111 to be in the state shown in the block 1. When a loop of a different loop type is formed in the same block, S1 is used.
It is sufficient to return to S10 from 2 and select the loop type again. When the input in block 1 is completed, whether or not to perform a knitted fabric simulation described later is selected in S13 of FIG. 6, but in the present embodiment, the knitted fabric simulation is performed when the input of all the design data is completed. In this case, S13 is passed. Then S1
In step 4, it is determined whether or not to correct the block 1 in which the input has been completed. If the correction is to be performed, the process returns to step S8 to perform the operation. Next, in S15, a selection is made as to whether or not to move the block for inputting design data to the next block, and the key 109 on the design data input screen is clicked in order to shift to input for the next block, block 2. As a result, after returning to S7, the process proceeds to a block obtained by adding 1 to the block number of the previous block, and the block number 2 is highlighted. Instead of clicking the next block key 109, the block number key 113 of the block to be input is used.
You may click.

In block 2, as shown in FIG. 3, design data for transferring the fourth table at the center of the needle bed before crossing to the rear needle bed is input. At S8, a transfer key 85 is clicked to select a transfer course. As a result, the loop locked in the block 2 in the block 1 in S16 is displayed by the green knitting yarn indicating that the loop is the transfer course, and the display unit 83 of the transfer course is highlighted. Transfer key 8
At the point when the user clicks on the number 5, the fourth table at the center remains locked to the needle of the front needle bed as in the case of the block 1. In step 17, the loop to be transferred is racked with the rear needle bed to a position facing the needle to be transferred. In block 2, however, the transfer is merely from the front needle bed to the rear needle bed, and the racking is performed. Since there is no racking position, the racking position is not specified here. Next, in S18, the loop of the needle bed before the transfer is clicked. As a result, the clicked loop becomes the jumping yarn 111 extending between adjacent loops.
Can be moved while connected. Next, in S19, the needle of the needle bed after the transfer is clicked. As a result, the loop is locked by the needle of the rear needle bed. After the loop to be transferred is designated, the operation of moving to the needle at the transfer destination is repeatedly performed for the fourth table, and the state shown in block 2 in FIG. 3 is obtained. If the loop designated for transfer is mistakenly transferred to another needle, the transfer loop may be specified again from S18.

Next, in block 3, a transfer course is selected in S8, and in S16, the same block as block 2 is indicated by a green knitting yarn indicating a transfer course.
Then, in S17, after the left arrow key 43 is clicked twice to specify the racking position of the needle 123 of the rear needle bed, the second eye on the upper side of the intersection is moved to the corresponding loop of the front bed in S18, By performing the step of S19, the screen is transferred to the front needle bed, and the state shown in block 3 of FIG. 3 is obtained. Next, in block 4 of FIG. 4, after specifying the transfer course in S8, the right arrow key 4
5 is clicked four times, the rear needle bed is racked to the position shown in block 4 in FIG. 4, and then the work of transferring the second eye below the intersection to the corresponding needle of the front needle bed is performed. The state shown in block 4 is obtained by performing steps S18 and S19. In block 5, after selecting the transfer course, the left needle key 43 is clicked twice to return the rear needle bed to the state of block 1 and 2 × 2.
The creation of the design data for forming the rope pattern is completed. After the completion of the input of the design data of the blocks 1 to 5, when returning to the already input block and performing the correction, the process proceeds from S21 to S22 to designate the block number to be corrected, and then perform the correction. . If no correction is made, the process moves from S21 to S23, and the creation of the design data is all completed. The design data created as described above is converted into control data for driving the flat knitting machine as necessary, and the created control data is transferred to the flat knitting machine via an external storage device such as a floppy disk. By inputting, knitting on the actual machine can be performed.

Next, a knitted fabric simulation for displaying a knitted fabric knitted based on the design data created as described above on a display will be described with reference to FIG. When performing a knitted fabric simulation, in S13,
By clicking the simulation key 131 provided at the lower right of the design data input screen shown in FIG. 3, a knitted fabric simulation screen as shown in FIG. 8 is displayed in S20. The knitted fabric simulation screen can be displayed at any time by clicking the simulation key 131. Also, the design data input screen and the knitted fabric simulation screen can be divided into two screens of the display, and the design data input screen and the knitted fabric simulation screen can be displayed side by side.

On the knitted fabric simulation screen, the basic image of the knitted fabric loop stored in the element storage means 31 is input by the loop input means 33 and the racking designating means 41 based on the design data input on the design data input screen. The knitted fabric simulation image is created by deforming based on the input design data. On the knitted fabric simulation screen, a loop formed as a face on the design data input screen is displayed in blue, and a loop formed as a back face is displayed in yellow. In the design device of the present embodiment, based on the design data input on the design data input screen, the basic knitted fabric stored in the element storage means on coordinates where the needle is taken in the horizontal direction and the course is taken in the vertical direction. An image of the loop is arranged, and an image of the jumping yarn connecting the basic knitted fabric loops is created. The side-transferred loop performs a deformation process on the basic knitted fabric loop image in accordance with the inclination obtained from the racking pitch, and then synthesizes it with another knitted fabric loop to create a simulation image. On the knitted fabric simulation screen, all loops input on the design data input screen are displayed, and are updated in real time in response to creation or correction of design data on the design data input screen. In addition, on the knitted fabric simulation screen, display is preferably performed in a state where the front and back stitches do not overlap even at the time of knitting of the rib knitting, in order to prevent the front and back stitches from overlapping and making it difficult to see.

In the above-described embodiment, a warning means for displaying a warning when a knitting command exceeding a racking limit value in the structure of the flat knitting machine is input is provided. Providing parameter setting means for inputting knitting conditions such as pull-down tension, knitting speed, knitting yarn material, etc., and when racking exceeding the allowable range of the input knitting conditions is specified, a warning such as "Yarn breakage" is displayed. May be configured to be performed. In the above-described embodiment, the warning is issued under the condition of the racking pitch. However, the warning is displayed not only when the racking is performed but also when a command such as transfer between the front and rear needles is input. The warning display is not limited to the case disclosed in the above description. Further, a key for inputting a knitting command other than knit, tack, and mistake may be provided. It should be noted that what has been described above is an example of the implementation of the design apparatus of the present invention, and individual configurations can be variously changed within the scope of the gist of the present invention.
