- the moving body holding mechanism is driven with the moving body holding mechanism.
- a carriage reciprocates along a needle bed.
- a cam mechanism mounted on the carriage performs a selective knitting operation on knitting needles arranged side by side along the needle bed.
- the yarn feeder force knitting operation that the carriage follows.
- the knitting of the knitted fabric is performed by supplying the knitting yarn to the knitting needle.
- a track called a thread path rail is installed above the tooth gap.
- a yarn feeder is provided at the end of the yarn feeder that can travel along the yarn path rail, facing the tooth gap, and the carriage drives the yarn feeder to supply the knitting yarn to the knitting needle.
- a yarn feeder is sometimes called a yarn carrier.
- a pin is provided on the bridge connecting the carriages on the front and rear needle beds so as to straddle the yarn path rail, and the pin protrudes and engages with the entrainment recess provided on the yarn feeder. Let me go.
- the supply of the knitting yarn from the yarn feeder to the knitting needle is performed in a normal knitting process while the knitting needle is retreating to the position where the needle bar has advanced most to the needle opening. Therefore, the yarn feeding position for supplying the knitting yarn to the generally mountain-shaped knitting cam mounted on the carriage is a position of the bottom of the mountain on a different side depending on the running direction of the carriage. The difference in the yarn feeding position depending on the running direction of the carriage is dealt with by extending the entrainment recess provided in the yarn feeder.
- the pin when the carriage travels to one side, the pin abuts on one end of the entrainment recess to entrain the yarn feeder, and when the carriage travels to the other side, the pin moves to the other side of the entrainment recess. If the yarn feeder is entrained by being brought into contact with the end on the side, the yarn feeder can be entrained at a position shifted according to the traveling direction of the carriage. When the timing of supplying the knitting yarn for knitting of the knitted fabric is different from the normal knitting described above There is also.
- a cam that causes the knitting needle to perform a knitting operation prior to a normal knitting cam is mounted on the carriage, and the knitting yarn that performs knitting of a normal course is precedently supplied in accordance with the cam.
- the knitting yarn is supplied.
- an elastic yarn or the like also called a rubber yarn is used for the knitting yarn for inlay knitting.
- plating knitting the knitting yarn is supplied later than the supply of the knitting yarn for knitting a normal course.
- the yarn feeder used for inlay knitting and plating knitting has a different length of entrainment recess than the yarn feeder used for normal knitting.
- the number of pins that carry the yarn feeder can be increased so that the yarn feeder can be used for normal knitting or staggered knitting (for example, German Patent Application Publication No. 4407708, See Registered Utility Model No. 3028923 and Patent No. 2733627).
- Fig. 1 shows a configuration in which a plurality of entrainment recesses are provided in the yarn feeder, and the positions of the entrainment recesses where the entrainment pins engage are changed to switch between inlay knitting and normal knitting.

- This biasing is performed counterclockwise with respect to the arm 113a and clockwise with respect to the arm 114a.
- the steps 113b, 113c; 114b, 114c at the tips of the arms 113a, 114a are biased so as to protrude toward the moving body holding mechanism 15.
- the rollers 118 and 119 are provided at positions where the rollers 118 and 119 protrude more than the step portions 113b and 113c; 114b and 114c. The rollers 118 and 119 come into contact with the operation bar 75.
- the swing displacement of the swing members 113 and 114 caused by the bias of the spring 117 is regulated by the rollers 118 and 119 abutting on the operation bar 75.
- the operation bar 75 forms a parallelogram link with the drive link piece 76 and the driven link piece 77 so as to be parallel to the track 18, and always keeps parallel to the longitudinal direction of the needle bed 2, that is, the direction of the track 18. .
- the parallelogram link receives the driving force of the motor 78 via the connection link 79, and can make a displacement such that the operation bar 75 comes into contact with or separates from the carriage 3. That is, the swing displacement of the swinging pieces 113 and 114 Can be changed in accordance with the distance between the operation bar 75 and the carriage 3 based on the angular displacement of the output shaft of the motor 78.
- the drive link 76 makes the maximum swing displacement clockwise around the swing shaft 76a at the upper end.
- the motor 78 is angularly displaced in either direction
- the drive link 76 is angularly displaced in the counterclockwise direction about the swing shaft 76a, and the operation bar 75 approaches the carriage 3 side. Therefore, as shown by the solid line in the figure, in the state of the connecting portion 76b of the drive link 76 to the operation bar 75, the operation bar 75 is farthest from the carriage 3.
- the step portions 113b and 114b of the swing members 113 and 114 face each other to form a driving recess that engages with the driving pin 112.
- ADVANTAGE OF THE INVENTION while moving along the needle bed of a flat knitting machine, it moves by being carried by the carriage which performs the knitting operation
- a track, a stopping mechanism, a moving body holding mechanism, and a driving state switching mechanism are included to enable switching of the moving state of the knitting moving body to be knitted.
- a stopping mechanism capable of stopping the knitting moving body is provided.
- a moving body holding mechanism capable of attaching and detaching the knitting moving body to and from the stationary mechanism when moving to the frame position; and a state in which the moving body holding mechanism is carried along with the carriage between the carriage and the carriage.
- an entrained state switchable to a state in which the vehicle is not entrained. Entrained state If the mechanism is switched to a state where the moving body holding mechanism is not entrained with respect to the carriage, the moving body holding mechanism and the knitting moving body can be separated and the carriage can be moved. Movement is possible.
- the entrainment state switching mechanism switches to a state in which the moving body holding mechanism is entrained with respect to the carriage, the knitting moving body is entrained to knit the knitted fabric while the moving body holding mechanism holds the knitting moving body. It can be carried out. For example, at the time of transfer, the moving body holding mechanism can be separated so that the moving body holding mechanism can be stopped at an appropriate position where the carriage does not move to the position of the stopping mechanism.
- the pattern knitting is performed by switching the knitting yarn with a glove finger or the like.
- the entrainment is performed by holding the yarn feeder to each of the front and rear moving body holding mechanisms up to the vicinity of the narrow knitting area and switching the entrainment of the front and rear moving body holding mechanisms at that position. Knitting can be performed efficiently. In this way, the switching state of the knitting moving body can be appropriately switched by switching whether or not to be entrained. Since the knitting moving body is detachable between the moving body holding mechanism and the stopping mechanism, the knitting moving body can be exchanged.
- the entrainment state switching mechanism switches the moving body holding mechanism having different entrainment positions with respect to the carriage before and after.
- Plating knitting can be performed by using the moving body holding mechanism to vary the timing of supplying the knitting yarn. Further, since the yarn feeder held by the front and rear moving body holding mechanisms can be switched, various plating knitting can be performed while changing the knitting yarn.
- an operation bar provided along a track and displaceable in a direction different from the direction along the track, and a displacement drive mechanism for displacing the operation bar in a direction different from the direction along the track.
- the entrained state control mechanism controls the operating state of the control member in conjunction with the operation bar being displaced in a direction different from the direction along the track.
- the entrainment state between the mechanism and the carriage can be switched by controlling the operation bar.
- the control member when the control member protrudes during operation, the control member comes into contact with the concave portion of the entrainment member, and the moving body holding mechanism can be entrained at an entrainment position different depending on the moving direction of the carriage.
- the control member when the control member protrudes at different entrainment positions according to the moving direction of the carriage, the control member abuts on the convex portion of the entrainment member, and the carriage can entrain the moving body holding mechanism.
