Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention is a method for separately retaining a plurality of knitting yarns for exchange and capture on a carriage slidably mounted on a knitting machine body, and for exchanging the knitting yarns. The present invention relates to a knitting yarn changing device for a knitting machine including a plurality of knitting yarn holders that are movable between an active position where the yarn is exchanged and an inactive position where the yarn is not exchanged.

[Prior Art] This type of device has been proposed by the same applicant, for example, in Japanese Patent Application No. 1983-
It is proposed as No. 207568. According to this existing proposal, a plurality of holders are provided on the outside of the knitting machine main body, each of which holds yarn feeder bodies through which knitting yarn is inserted in a detachable manner, and which can be switched between a non-working position and a working position. is provided, and when the carriage is slid from the knitting section toward the holder group with one empty holder of the holder group with the yarn feeder removed in the working position, The yarn feeder body is delivered to the empty holder. Only one holder holding the newly selected yarn feeder body is then switched to the working position, after which the carriage is slid from the outside of the holder group towards the holder group, thereby A new yarn feeder on one holder is received by the carriage. As the carriage slides, knitting yarn is supplied from a new yarn feeder to each knitting needle in the knitting section.

However, in the above-mentioned knitting machine, the holder group is only provided on one side of the knitting section, so the knitting yarn is replaced on the other side of the knitting section opposite to the holder group. However, since the same knitting yarn can only be knitted in units of two courses, there is a problem in that the creation of patterns and color schemes are restricted. Therefore, the inventor of this output side arranged the same number of holders as the knitting yarns to be exchanged on the left and right sides of the knitting section, and exchanged the knitting yarns between each holder group and the carriage. He devised a device that

In this device, as shown in FIGS. 14(a) to 14(d), the arrangement order of the holders in each holder group is set to increase from left to right, and the holders having the same arrangement order Each knitting yarn is transferred between the machine and the carriage.

That is, in the above-mentioned apparatus, for example, as shown in FIG. 14(a), after the knitting yarn Y1 held by the first holder on the left is delivered to the carriage, as the carriage moves to the right, This knitting yarn Y1 becomes knitting yarn Y2 as shown in FIG. 14(b).
．． After passing behind Y3 and reaching the group of holders on the right, the knitting yarn Y1 is transferred to the first holder on the right, and the knitting yarn Y4 held in the fourth holder on the right is transferred to the carriage. Then, as the carriage moves leftward, knitting yarn Y4 passes behind knitting yarn Y1 and reaches the left holder group, as shown in FIG. 14(c).
4 is passed to the fourth holder on the left.

However, in the above state, when the carriage is reciprocated and the knitting yarn Y1 is transferred from the right holder to the left holder again, the knitting yarn Y1 is transferred as shown in FIG. 14(d). There was a problem in that it became entangled with the knitting yarn Y4, making it difficult to continue the knitting operation.

This invention was made in consideration of the above-mentioned circumstances, and its purpose is to determine how to use the order of use of each set between the left and right holder groups to allow the carriage to exchange and capture various knitting yarns. To provide a knitting yarn exchange device for a knitting machine that can smoothly perform knitting yarn exchange and knitting operations without the fear of knitting yarns getting tangled even when the knitting yarns are exchanged after setting.

[Means for Solving the Problems] In order to achieve the above object, in the present invention, the same number of knitting yarn holders as the knitting yarns to be exchanged are slid on a carriage at predetermined positions on both the left and right sides of the knitting section of the TA main body. The knitting yarn holders arranged in the same order from the inside to the outside of each left and right knitting yarn holder group are set as a set, and between the left and right knitting yarn holders in each group. The configuration is such that one knitting yarn is delivered to and from each via a carriage.

[Operation] When exchanging knitting yarn between the carriage and the left and right holder groups, one knitting yarn is transferred between the left and right knitting yarn holders in each group via the respective carriages.
