騒音による環境の弊害もあった。(Problems to be Solved by the Invention) In the above-mentioned conventional technology, the dowel that is in one of the lower operating positions at the knitting end is moved upward to the upper rest position, and after both are in the upper position, The operation of selecting the sewing thread located at the rear and setting it to the lower stitching position is performed when the knitting carriage reaches the knitting end, for example, when a driven member such as a slider or a rotating piece installed on the carriage is installed at the knitting end. This is done by an interlocking mechanism that uses a collision action with a fixed member such as a cam or a receiving piece. Therefore, this interlocking mechanism device complicates the structure of the knitting machine, puts a heavy burden on design and manufacturing, and reduces the impact of members. When the knitting width changes due to the joining operation, it is necessary to change the position of the fixed matching member accordingly, and this change generally requires manual intervention, and especially when fine adjustment is required, the effort is extremely troublesome. In addition, there were other environmental problems due to the noise generated during collision.

用点の高速切換えに不利であった。Furthermore, the cam used for setting the stitch position in the conventional means is a spiral cam having a parabolic working surface, and when used, for example, the cam operating point can be changed from the shortest diameter part to the longest diameter part or the maximum diameter part. When changing from the long diameter portion to the shortest diameter portion, it is necessary to rotate the cam by the entire length of the cam operating surface, which is disadvantageous for high-speed switching of the point of action.

的確に与え得る。(Function) The stitch conversion actuating device according to the present invention sets the longest diameter part of the eccentric circular cam whose entire circumferential surface is the cam actuating surface as the actuating point by applying an electric signal of a set number of pulses to the motor at the knitting end. As a result, the interlocking mechanism is operated with maximum momentum, - the sliding piece of the dowel, which was at the lower stitch position at the rear position with respect to the direction of the bottom of the knitted knitting, and the sliding piece of the dowel, which is located in the front with respect to the direction of the bottom of the knitted knitting, is The sliding piece of the other dowel, which was held in the upper rest position slightly below the upper limit position, is moved upward to the upper limit position together with the sliding piece of the other brace.
During the upward movement, the sliding piece that has moved upward from the lower stitch position is locked by the locking mechanism, and the locking portion of the other sliding piece that has moved upward from the locked state becomes slack. At this point, an electric signal is sent to the solenoid attached to the locking mechanism on the one side of the slide where the lock is loosened, and the solenoid is energized to release the lock on the sliding piece. When the motor rotates the circular cam a desired amount from the stopped state at the longest diameter section using an electric signal that sets the stitch position in the knitting course, the unlocked sliding piece moves downward under the force of the traction spring. , a sliding piece that moves downward is supported against a traction spring by an interlocking mechanism that is operated according to a set position of a cam operating surface of the circular cam that is set by a predetermined amount, and the stitching thread is set and held at a desired stitch position; By performing the above operations at both ends of the formation, it is possible to smoothly repeat the conversion of left and right peaks during reciprocating movement of the carriage, and since the activation is performed by an electric signal, the activation command can be issued at any time. The conversion operation command can be accurately given at any time between the completion of one course's composition and the next course's composition.

る。Furthermore, the entire circumference of the eccentric circular cam can be used as a continuous cam operating surface, and when the cam operating point is selectively moved by rotating the cam, the circular cam can be rotated in any direction. The operating point in use can be quickly set to the next desired operating point with the minimum amount of rotation, and in combination with the start command means using an electric signal, it is possible to quickly respond to high-speed operation of the knitting machine.

In this state, the knitting progresses, and before the knitting of one course is completed and the next course is knitted, a signal pulse is sent to the motor (6) to move the longest diameter point (7b) of the circular cam (D) as shown in Fig. 1. As shown by the line, if the circular cam (D) is rotated a predetermined amount so as to be in contact with the movable piece (+(I), it will be locked at the stitch actuation position (2) and at a position slightly below the upper limit position. The rest position (2 degrees) both move upward to the upper limit position, and at this time, the locking piece (12b) is automatically stepped by the spring (12c) against the left sliding piece (4). The right sliding piece (4°) is at its upper limit position and gives a command signal to the solenoid (12a) to loosen the locking relationship by moving upward to the upper limit position. The locking piece (12b) is detached.Synchronized with this, the circular cam (D) is rotated by a predetermined amount by a pulse signal to the motor (6), and the desired operating point of the cam operating surface is set relative to the moving piece GO. By bringing them into contact, the rotating pieces 01) (11°) on both sides rotate together, and the arm (11b) of the left rotating piece (Iv) is in a lower position separated from the lower surface of the sliding piece (4), and the corresponding The sliding piece (4) is locked by the locking mechanism 021 at a position slightly below the upper limit position and held at the rest position, and the arm (llb) of the right sliding piece (4°)
) also moves downward, and the downward movement position is the setting of the stitch amount, and at this position, the lock is released and the traction spring (9) supports and holds the sliding piece (4゛) that descends under the biasing force. Therefore, the right stitch (2°) becomes the operating position for the desired stitch amount.

することができる。Furthermore, since the entire circumference of the circular cam (7) can be used as the working cam surface, by commanding the direction of rotation when the circular cam (7) is rotated, the desired set position facing the movable piece (1G) can be moved from the stopped position. It can be selectively rotated in a direction with a small amount of rotation to perform a quick conversion operation, and can cope with high-speed operation of the knitting machine, and corresponds to the rotation direction selection command to the motor (6) and the stitch amount. The amount of rotation can be commanded in a timely manner based on data input into the computer in advance.

相俟って編機の高速運転に対処し得る効果を有する。(Effects of the Invention) According to the present invention, an eccentric circular cam that is interlocked with a motor is provided between a pair of threads and the left and right sliding pieces that are integrally connected to each other, and the entire circumference of the eccentric circular cam is used as an active cam surface. Depending on the direction of rotation of the cam, which rotates in response to a signal, and the desired amount of rotation, the sliding piece is at the stitching operation position in the previous knitting process, and the sliding piece is at the rest position, where it is locked slightly below the upper limit position. At the upper limit position, the locking mechanism is applied to the sliding piece on the side to be next set to the rest position, and the locking on the sliding piece on the side to be set to the stitching position is released. Then, this is moved down by a spring to the stitch operation position, and the stitches are converted.The conversion operation is performed by the rotation of a circular cam, and the conversion operation is performed by an electric signal to the motor commanded by the computer. Since the actuation and release of the locking mechanism are performed by a solenoid, the use of conventional mechanical devices such as abutment operation can be omitted, and the adjustment can be made in a timely and accurate manner. Since the entire circumference of the cam is used as the cam operating surface, it is possible to command the direction of rotation of the cam and set the point of action on the cam operating surface in a short time with the minimum amount of rotation. Together, they have the effect of being able to cope with high-speed operation of the knitting machine.
