Description

KNITTING METHOD BY FLAT KNITTING MACHINE AND APPARATUS FOR EDITING OF KNITTING DATA}

The present invention relates to knitting in flat knitting machines, and more particularly, to improvement of knitting efficiency.

In the flat knitting machine, for example, the needle of the needle bed is operated by a cam system built in the carriage by reciprocating the carriage on a pair of front and rear needle beds. Many cam systems are provided, for example, two or three for the front needle bed and the rear needle bed. In addition, since the cam system is provided in the same number of front and rear needle beds, the number of the cam systems is often indicated by the number of cam systems for one needle bed. For example, a carriage having two cam systems each before and after is called a carriage of two cams (system). The needle is present in the needle bed, and the needle is suddenly discharged from the carrier, the needle is selected by the needle tip of the cam system, and the needle is operated by the cam cam of the cam system. To operate a knit, tuck, transfer, or the like. One movement of the carriage is called one course, and stitches for one row along the moving direction of the carriage are also called one course, and whether the course of the carriage or the course of the stitch is determined from the context of the discussion. The installation of a plurality of cam systems in the carriage may include stitching a plurality of courses by one course of the carriage, forming a stitch by one cam system, and transferring the other by a cam system. Because it can.

In flat knitting machines, one course knitting is performed by the same cam system. For example, in the case of a transfer course, all of the courses are transferred by the same cam system even by a carriage having a plurality of cam systems. This is common sense of knitting in flat knitting machines.

The time required for knitting the knitted fabric becomes longer as the stroke of the carriage increases. For example, Patent Document 1 (WO2008 / 078415) discloses a technique for shortening the stroke required for preliminary needle needle. The example described in patent document 1 is shown in FIG. Here, the knitting is done from the left side to the right side of the drawing, where S2 is a knitting operation by the preceding cam system, and S1 is a trailing cam system, and is stopped here. The preceding / following is determined by the direction of carriage movement on the course, and the stop means not to operate the knitting cam. W is a knitting width and is the width of the section from the knitting needle first operated in the direction of carriage advance to the knitting needle last operated. L is the stroke of the carriage. The cam systems S1 and S2 are provided with the knitting cam 2 and the needle tip 4, and the pair of needle tip 4 is provided before and after the knitting cam 2. In order to needle a needle, a preliminary needle is applied to a needle that misses and a needle that operates a knit, a jaw, a transfer, and the like, and then a needle is needled to a needle to knit or transfer and a needle to jaw. Since the needle tip 4 can only be a first-stage needle tip, a preliminary needle tip is performed by the tip needle part 4b of the preceding cam system S2 at the end of the course. When the carriage is reversed, the same needle tip part 4b is again present. The main needle is made by the t), and is knitted by the knitting cam of the cam system S2. If the preliminary needle at the end of the course is made by the needle tip 4a of the cam system S1, the stroke is lengthened by the length of the chain line in FIG. In contrast, when the preliminary needle and the main needle for the start of the next course are combined by the needle tip 4b of the cam system S2, the stroke can be shortened.

As shown in Fig. 10, the knitting for one course is all made by the cam system S2, and the cam system S2 is stopped in the middle of one course, and the cam system S1 is operated instead. It is not described in patent document 1. In addition, although one course may be knitted by cam system S1, cam system S2 is stopped in that case.

WO2008 / 078415

An object of the present invention is to shorten the stroke of the carriage and to improve the knitting efficiency of the flat knitting machine.

The present invention includes a needle bed, a carriage, a carrier and a controller, wherein the carriage comprises two or more cam systems along the length of the needle bed. In the knitting method using a flat knitting machine which is provided and knitted using the yarn from a carrier by the said cam system,

For a course of carriage in which the yarn from the carrier is not suddenly threaded to the needle of the needle bed and the knitting width exceeds the width of the 1 cam system,

The knitting width is divided into at least two parts of different cam systems, and the sum of the knitting width of the first portion and the knitting width of the last portion in the direction of carriage advance is greater than or equal to the width of one cam system. Set the knitting width of the first part and the knitting width of the last part so that

The first part is knitted by a trailing cam system along the direction of carriage and the last part is knitted by a preceding cam system along the direction of carriage.

Here, the knitting width of the course of the carriage is the width of the section from the knitting needle first operated in the advancing direction of the carriage to the knitting needle last operated. The knitting width of the first portion is the width of any section from the knitting needle first operated by the trailing cam system to the rear in the direction of carriage advancement, from the knitting needle operated by a cam system other than the trailing edge. . The knitting width of the last part is the width of an arbitrary section from the knitting needle last operated by the preceding cam system to the front in the carriage direction of travel, and continuously to the knitting needle operated by a cam system other than the preceding one. .

In addition, the present invention includes a needle bed, a carriage, a carrier and a controller, and the carriage includes two or more cam systems along the length direction of the needle bed and is knitted by using the seal from the carrier by the cam system. A device for editing knitting data for flat knitting machines,

Course identification means for identifying the course of the carriage whose knitting width exceeds the width of the 1-cam system without analyzing the knitting data and suddenly threading the needle from the carrier to the needle of the needle bed;

The knitting width of the course identified by the course identification means is the sum of the knitting width of the first portion and the knitting width of the last portion in the carriage direction when the cam system to be used is divided into at least two other portions. In the case where the width is greater than the width of the 1 cam system, the first portion is knitted by a trailing cam system along the carriage direction, and the last portion is automatically knitted by the preceding cam system along the carriage direction. And an allocating means for allocating the cam system.

The knitting width of the first portion may include a section in which the needle bed needle is not operated by either cam system, in addition to a section in which the needle bed needle is operated by the trailing cam system. The knitting width of the last portion may include a section in which the needle of the needle bed is operated by the preceding cam system, and a section in which the needle of the needle bed is not operated by either cam system. In other words, the knitting width of the first portion is the width of the sum of the sections in which the following cam system operates the needle and in which no cam system subsequent to the section operates the needle. Similarly, the knitting width of the last part is the width of the sum total of the section in which the preceding cam system operates the needle and the section in which neither cam system subsequent to the section operates the needle. Further, when operating the needle of the needle bed with respect to the knitting width between the first portion and the last portion, the needle is operated by the preceding cam system and / or the following cam system.

Preferably, the course is a course for transferring the stitches. Knitting without feeding the yarn from the carrier, i.e. without forming a stitch, transfers the transfer by knitting a cable pattern, narrowing, widening, stitching, or the like. This is the case. For example, although the knitting pattern of the cable pattern is shown in Fig. 5, the carriage has three courses of transfer when the course of stitch formation is three courses. If the stroke in the transfer course is shortened by the width of the 1 cam system, for example, the knitting time can be reduced by a few%. In addition to the transfer, the carriage is also moved without using a carrier in an operation of casting off a stitch from a needle.

In the present invention, as shown in Figs. 1 to 4, the stroke of the carriage can be shortened. For example, comparing FIG. 1 and FIG. 10, in the carriage provided with two cam systems, the stroke can be shortened by the width of one cam system. In the carriage provided with three cam systems as shown in Fig. 3, the stroke can be shortened by the width of the two cam systems. This is because the first part of the course is organized by the following cam system S1 or the like, and the last part of the course is organized by the preceding cam system S2 or the like.

In the case where the carriage is provided with three or more cam systems, it is preferable to start the knitting by the last cam system and to finish the knitting by the best cam system. For example, the knitting may be started by the last cam system, and the knitting may be ended by the central cam system. The central cam system does not have to be used.

The knitting device for editing the knitting data is embedded in, for example, a flat knitting machine or a knit design device. If the editing apparatus is incorporated in the flat knitting machine, the flat knitting machine can edit existing knitting data to implement the present invention. If the editing device is incorporated in the knit design device, the knitting data can be edited to implement the present invention when designing a knit fabric and creating the knitting data.

In this specification, the description regarding the knitting method is suitable for the editing apparatus of knitting data as it is, and the description regarding the editing apparatus for the knitting data is suitable for the knitting method as it is. In the case where the first part of the course is organized by a trailing cam system along the direction of carriage and the last part of the course is organized by the preceding cam system along the direction of carriage, the gap between the first part and the last part is The cam system may be formed by any of the preceding and following cam systems, or may be formed by both the preceding and following cam systems. The width of the 1 cam system is the length from the start of the knitting operation including the needle to the one cam system until it ends. In addition, when the knitting width of the course is less than the width of one cam system, it is effective to organize all the knitting widths by the trailing cam system. However, since the knitting width is less than the width of one cam system, the knitting may be started by, for example, the following cam system, and the knitting may be finished by the preceding cam system.

Fig. 6 shows an example in which the stroke is the same in the present invention and the conventional example, and the knitting width W in this case is equal to the width of the 1 cam system. Here, there is no meaning of implementing the present invention when the knitting width is less than the width of the 1 cam system, and the stroke is the same even if the present invention is not implemented when the knitting width is the same as the width of the 1 cam system. However, since the knitting width is less than the width of the 1 cam system, it may be knitted in the same manner as the present invention regardless of the knitting width.

In addition, as shown in the course C4 of FIG. 5, when the first part of the knitting width can be knitted by any of the preceding and following cam systems, the strokes of the carriage become the same even if the embodiment is not applied. Therefore, as a condition to apply the embodiment, it may be added that the first part of the knitting width can be knitted only by the following cam system.

Hereinafter, the best mode for carrying out the invention will be described.

(Example)

1 to 9, the arrows indicate the moving direction of the carriage, ON indicates that the cam system is knitted, and OFF indicates that it stops. Fig. 1 shows the allocation of the cam systems S1 and S2 to the knitting only of the transfer, and Fig. 2 shows the on / off of the cam systems S1 and S2 at that time. The first portion of the knitting width W is knitted by the trailing cam system S1, and the last portion is knitted by the preceding cam system S2. The part in the middle can be knitted by either one or both of the cam systems S1 and S2. 1 and 2, the knitting width of the first portion and the knitting width of the last portion are set equal to the width of one cam system, respectively.

The solid line in Fig. 2 shows an example of preferentially using the cam system S2, and the broken line shows an example of preferentially using the cam system S1. In either case, the cam systems S1 and S2 are together. There is a period in use. 1 and 2, when the knitting width W is long, the stroke stroke L and the knitting width W of the carriage are almost the same, and compared with FIG. It is shortened by the width of one cam system along the longitudinal direction of the needle bed. And this is particularly advantageous in the transfer-rich knitting, but the embodiment can be applied to the cast-off of stitches in addition to the transfer.

Fig. 3 shows the assignment of cam systems S1, S2, S3 to a course of transfer only in a carriage provided with three cam systems S1, S2, S3. Fig. 4 shows an example of the allocation of the cam systems S1, S2, S3 to the course of Fig. 3, where the solid line shows an example of using the cam system S2 first, and the broken line gives the cam system S1 first. The example to use is shown. 3 and 4, the stroke L is shorter than the knitting width W. The start of the knitting width uses the cam system S1, and the end of the knitting width uses the cam system S3. use. At the center of the knitting width, at least one of the cam systems S1, S2, and S3 may be used, and two or three cam systems S1, S2, and S3 may be used. At least one of the cam systems S1 and S2 is used between the center part and the beginning of the knitting width, and at least one of the cam systems S2 and S3 is used between the center part and the end of the knitting width. In this example, there are periods in which the cam systems S1 and S2 are used together, and periods in which the cam systems S2 and S3 are used together.

5 shows an example of a knitting pattern of a cable pattern, and the cable pattern is knitted by repeating the courses C1 to C6. The carriage is provided with two cam systems, and in the courses C1 to C3, two rows of stitches are knitted in total for each course. The stitch is transferred at course C4, the rear needle bed is racked to the left before course C5, and about half of the transferred stitch is moved back to the front needle bed. Then, before the course C6, the rear needle bed is racked to the right, and the rest of the transferred stitches are moved to the front needle bed and returned.

In the course C4, the end of the knitting width is extended by the stroke unless it is knitted more than the width of one cam system by the preceding cam system. This is because, if the end portion of the knitting width is allocated to the preceding cam system only less than the width of one cam system, the following cam system knits the allocated portion, so that the stroke extends to the left side conventionally. In addition, the start of the knitting width can be organized by any of the preceding and following cam systems. In such a case, even if the embodiment is not applied, the stroke is not changed, and the stroke can be shortened when the starting portion of the knitting width can be knitted only by the following cam system.

In the courses C5 and C6, in the embodiment, knitting is started by the following cam system, and knitting is finished by the preceding cam system. On the other hand, in the prior art, for example, the course C5 is consistently knitted by the trailing cam system, and the course C6 is consistently knitted by the preceding cam system. This makes it possible to shorten the stroke by the width of one cam system in the embodiment in the courses C5 and C6. If the total stroke can be reduced by twice the width of the cam system for six courses of the carriage, the knitting time is reduced by a few percent.

6, the lower limit of the knitting width | variety which can shorten a stroke by an Example is shown. 1) in Fig. 6 shows a stroke in the embodiment, and 2) shows a stroke in the conventional example. In 1) in FIG. 6, the sum of the knitting width of the first portion knitted by the following cam system S1 and the knitting width of the last portion knitted by the preceding cam system S2 is the sum of the one cam system. The width is the same, and the stroke is the same in the embodiment and the conventional example. 6, the sum of the knitting width of the first portion and the knitting width of the last portion is equal to the knitting width W. In FIG. When the sum of the knitting width of the first portion and the knitting width of the last portion is equal to the width of one cam system, in the embodiment, the allocation of the cam system is changed by the initial position of the carriage for the knitting width. In either case, however, the stroke L1 of the carriage is 2W, which is twice the width of the cam system. In the conventional example, when the knitting width W is knitted, the carriage must move a stroke by the width of the knitting width W + 1 cam system, and the stroke is 2W in this case. Therefore, when the knitting width W is equal to the width of the 1 cam system, the stroke of the carriage becomes the same in the embodiment and the conventional example.

FIG. 7 shows a process relating to the shortening of the stroke, which is performed by the knit design device 10 of FIG. 8 or the flat knitting machine 30 of FIG. Step 1 of Fig. 7 reads the knitting data for one course, determines whether or not the course uses the carrier in step 2, and if the course does not use the carrier, for example, a transfer or cast-off course, the knitting is not performed. It is checked whether or not a cam system of allocation exists (step 3). In addition, whether the knitting width can be divided so that the sum of the knitting width of the first part and the knitting part of the last part in the direction of carriage advance becomes more than one cam system, and the cam system used in the first part and the last part is different. (Step 4). If it is not possible to divide, transfer of one course is performed by the same cam system as before. If it is possible to divide, in step 5 the knitting system is started by the following cam system according to the embodiment, and the cam system is allocated to finish the knitting by the preceding cam system. Between the first part and the last part of the knitting, either one or both of the preceding cam system and the following cam system are knitted, and the process ends if there is no next course (step 6). As a result, the stroke can be shortened. Further, the embodiment may not be applied when the course starts from the position where the knitting can be started by the preceding cam system.

Fig. 8 shows the knit design device of the embodiment, where 12 is a mouse and may be another pointing device, 14 is a keyboard, 16 is a printer of color, for example, 18 is a monitor of color, for example. Reference numeral 20 designates a design support section, and provides an environment for editing a design of a knitted user input from a mouse 12, a keyboard 14, an input / output 26, etc., and making the design easier. 22 is a data conversion section, which converts the design of the knitted fabric into knitted data, 24 is a stroke shortening section, and a course capable of shortening the stroke by performing the process shown in FIG. Change the organization data. The stroke shortening portion 24 analyzes the knitting data and does not suddenly thread the thread from the carrier to the needle of the needle bed, and identifies the course whose knitting width exceeds the width of the 1 cam system. The sum of the knitting width of the first part and the knitting width of the last part in the direction of carriage advance when the cam system used divides the knitting width of the identified course into two or more other parts. If the cam system is larger than the width of one cam system, the cam system is automatically arranged so that the first part is knitted by the trailing cam system along the carriage direction and the last part is knitted by the preceding cam system along the carriage direction. It has a means of assigning (割 當 手段). 26 is an input / output and outputs knitting data by inputting the design of the knitting. The printer 16 may not be necessary. In addition, a course in which the user does not suddenly thread the thread from the carrier to the needle of the needle bed may be subjected to a process in which the cam system used by the user using a design device or the like is divided into at least two or more parts, or the course is cammed. In addition to dividing the system into at least two other parts, the knitting width of the first portion and the width of the knitting width of the first portion and the knitting width of the last portion in the direction of carriage advancement are equal to or greater than the width of one cam system. The stroke shortening part 24 may be provided with the setting means which sets the knitting width of a last part.
