Description

[Detailed Description of the Invention] [Industrial Application Field] This invention allows a plurality of knitting yarns to be individually held in a carriage slidably mounted on a knitting machine body for exchange and capture, and the knitting yarns to be exchanged. The present invention relates to a knitting yarn changing device for a knitting machine, which includes a plurality of knitting yarn holders that are movable between an active position where changing occurs and a non-active position where changing is not performed.

[Prior Art] Conventionally, it has been assumed that the thread transfer between the carriage and the knitting yarn holder is carried out normally unless a mechanical problem occurs, and the color scheme data numbers are Knitting was done based on the interpretation of thread holder numbers.

[Problems to be Solved by the Invention] However, since the knitting yarn holder does not have a sensing means when the yarn end is captured, even if the yarn end falls off from the knitting yarn holder, knitting will continue and the knitting will be interrupted. There was a risk that the ground would drop or the knitted fabric would become abnormal.

Also, the color scheme data number is interpreted as the knitting yarn holder number, so for example, in the first pattern, the red knitting yarn is number 1 data, and in the subsequent pattern, the same red knitting yarn is number 3 data. When moving from the first pattern to the next pattern,
It was necessary to once remove the knitting yarn from the tension applying mechanism, move the knitting yarn to the No. 3 position, and pass it through the No. 3 tension applying mechanism again.

The present invention has been made in order to solve the above-mentioned problems, and the first object is to provide the knitting yarn holder with a yarn head sensing means, so that when the yarn head is transferred to the knitting yarn holder, it can be detected without error. The purpose is to confirm that it has been maintained.

The second purpose is to provide a dividing means for differentiating yarn ends from each other, so that when knitting multiple patterns in succession, for example, even if the red knitting yarn has different data numbers between patterns, only the yarn ends can be separated. The reason is that all you have to do is replace the .

[Means for Solving the Problems] In order to achieve this object, the knitting yarn changing device of the present invention has, in particular, a dividing means in each yarn opening that can be distinguished from other yarn openings, and in which each yarn The holder has sensing means for identifying and sensing the thread sorting means.

[Operation] When exchanging knitting yarn between the carriage and the left and right holder groups, one yarn opening holding the knitting yarn is transferred between the left and right knitting yarn holders in each group via the carriage. , when passing the yarn from the carriage to the knitting yarn holder,
The sensing means of the knitting yarn holder identifies and senses the dividing means provided on the yarn opening, thereby confirming that the yarn opening has been received, and identifying whether or not the correspondence between the yarn opening and the knitting yarn holder is correct. .

It is switched to a release position where the holder 18 is released from the holder 18 by moving away from the holder 1b. Furthermore, an actuating piece spring 38 is hung between each actuating piece 37 and the second support arm 36, and each actuating piece 37 is urged toward the locking position by the spring 38.

An actuating piece control plate 39 corresponding to each actuating piece 37 is supported by the first support arm 33 so as to be movable up and down, and its lower end abuts each actuating piece 37, and its upper end is placed above the frame body 29. protrudes to. Then, by lowering the three actuating piece control plates, each actuating piece 37 is swung from the locking position to the release position against the biasing force of the spring 38. Each actuating piece control plate 39 is always operated by the biasing force of the spring 38.
It is held in the upper position via the actuation piece 37.

Electromagnets 35 corresponding to each actuating piece 37 are arranged in parallel on the second support arm 36, and the attractive force of each electromagnet 35 is set to be larger than the biasing force of the actuating piece spring 38.
The biasing force of the holder spring 34 is set smaller than that of the holder spring 34. Therefore, even if the electromagnet 35 is energized with each holder 18 being locked and held in the non-operating position by each actuating piece 37, each actuating piece 37 will not be swung from the locking position to the release position. Instead, when the locking of each holder 18 by each actuating piece 37 is released by the action of the actuating piece control plate 39, each electromagnet 35 is energized, thereby resisting the biasing force of the actuating piece spring 38. , the rear end of each actuating piece 37 is attracted, and the actuating piece 37 is held at the release position by the suction force.

On the other hand, as shown in FIGS. 2(c) and 2(d), on the lower surface of the machine carriage 13, below one of the thread holder holders, each of the holders 18 is placed between the working position and the non-working position.

As shown in clue number 1, in the state where only Pl exists,
When the thread 17 is captured by the thread holder 18, the electrodes Tla and Tlb are short-circuited by the conductor P1, and the other electrodes T2a and T2b and T3a and T3b are released, so the CPU 100 This makes it possible to know with certainty that the clue is held in the right holder No. 1 (S11). After this, the solenoid is turned off (S12).

Also, if the determination in S14 is NO, then S1
Proceeding to step 6, the carriages 13 and 14 are slid to the right in the same way as in S8, but since they only go toward the right knitting yarn restraining device 16a to pick up the yarn, needle selection is not performed and the carriages remain in the "sliding" state. At this time, the right knitting yarn restraining device 16a selects the working position of the right holder 1 (S17).
It is 8.

Repeat the above operation for other stages.

[Effects of the Invention] As is clear from the detailed description above, according to the present invention, each yarn opening is provided with a dividing means that can be distinguished from other yarn openings, and each knitting yarn holder is provided with a dividing means for distinguishing one yarn opening from another. By disposing a sensing means to identify and sense the sorting means, it is possible to identify the correspondence between each knitting yarn holder and the yarn end set therein.First, it is possible to ensure that the yarn end is captured by the holder. This can prevent troubles in which the knitting operation continues with the threads falling off. Second, the color scheme data number can be interpreted as a clue number rather than a holder number as in the past.

For example, in the past, when you wanted to knit a pattern in succession, the red knitting yarn was stored as data No. 1 for the previous pattern and data No. 3 for the next pattern. When transferring, knitting was performed by removing the knitting yarn from the tension applying mechanism No. 1, changing the location of the knitting yarn, and passing it back through the tension applying mechanism No. 3, but according to the present invention, The granting mechanism and holder will continue to have the same number, and you can just change the clue from number 1 to number 3.
It has the excellent effect of allowing work to proceed efficiently.
