The present invention relates to a yarn feeder for a knitting machine TECHNICAL FIELD The present invention relates to a yarn feeder for a knitting machine, (a yarn-supplying apparatus in knitting machine) and a yarn feed system for a knitting machine. BACKGROUND ART A conventional circular knitting machine is provided with yarn feeders arranged along the verge of a cylinder. A plurality of yarns of different colors or different qualities are fed selectively by each of the yarn feeders to form a pattern in a knitted fabric. Each of the plurality of yarn feeders has a plurality of yarn guide arms respectively provided in their tips with eyes. One of the plurality of yarn guide arms of each yarn feeder is operated selectively to guide a selected yarn to a knitting position or to retract a selected yarn from the knitting position. As mentioned in Patent documents 1, 2 and 3, the yarn guide arms are operated by yarn selecting means, such as actuators or solenoids according to signals read from a storage medium. The motions of the selecting means, such as actuators, are transmitted directly or indirectly to the yarn guide arms. The motion of the actuator according to the signal read from the storage medium is completed by the movement of a vibrational finger included in the actuator from a waiting position to a working position. The vibrational finger returns to the waiting position after completing the motion. The motion of the vibrational finger is completed in a predetermined short time. When operations for moving the yarn guide arm a position where the butt of the yarn guide arm is able to engage with a yarn guide arm control cam by the actuator and for advancing the yarn guide arm to a feed position by the yarn guide arm control cam are performed even slightly improperly, it is possible that the butt of the yarn guide arm is unable to engage with the yarn guide arm control cam or that those members are damaged due to interference with each other or with other members, causing the knitting machine to stop. The actuators or the solenoids need to be combined with the yarn feeders disposed at different positions, respectively, and the yarn feeders need to be provided with one actuator or one solenoid to operate one yarn guide arm for guiding one yarn. Thus, the total number of the actuators or the solenoids is equal to the number of yarns to be fed by the yarn feeders. Patent document 1: JP 50-6578 B Patent document 2: JP 52-110964 A Patent document 3: JP 1-21988 U DISCLOSURE OF THE INVENTION Accordingly, it is an object of the present invention to prevent the irregular movement of a plurality of yarn guide arms included in each of a plurality of yarn feeders arranged on a circular knitting machine by a locking mechanism capable of securely holding the yarn guide arm selected by a yarn guide arm selecting member operated by a selector operating device, such as an actuator, and advanced to a yarn feed position so that a part of the yarn guide member is located on the path of a yarn guide arm control cam at the yarn feed position. Another object of the present invention is to provide a yarn feeder of simple construction provided with a plurality of yarn guide arms and a single yarn guide arm selecting means, such as an actuator, capable of moving in the yarn feeder to operate the yarn guide arms selectively. A third object of the present invention is to provide a yarn feeder provided with a plurality of yarn guide arms, and a movable cutting blade interlocked with the yarn guide arms for reliable cutting operation. A yarn feeder in a first aspect of the present invention for a knitting machine includes: a plurality of yarn guide members each provided with a cam follower; a plurality of yarn guide member selecting members respectively corresponding to the yarn guide members; and a locking mechanism capable of securely retaining each of the yarn guide members selected and moved to a working position where the cam follower of the yarn guide member is located on the path of a yarn guide member control cam by the corresponding yarn guide member selecting member at the working position. In the yarn feeder according to the present invention, the locking mechanism is capable of securely holding the selected yarn guide member at the working position with its cam follower located on the .path of the yarn guide member control cam in a period immediately before a time point when the yarn guide member starts advancing to a yarn feed position and in a period immediately after a time point when the yarn guide member starts retracting from the yarn feed position. The yarn feeder according to the present invention may be provided with yarn cutters respectively combined with the yarn guide members and each including a stationary blade, and a movable blade interlocked with the yarn guide member and capable of being moved relative to the stationary blade to cut a yarn by the yarn guide member when the yarn guide member retracts from the yarn feed position. A yarn feed system for a knitting machine, includes: a plurality of yarn feeders each including a plurality of yarn guide members each provided with a cam follower, a plurality of yarn guide member selecting members respectively corresponding to the yarn guide members, and a locking mechanism capable of securely retaining each of the yarn guide members selected and moved to a working position where the cam follower of the yarn guide member is located on the path of a yarn guide member control cam by the corresponding yarn guide member selecting member at the working position; and a single selecting means capable of traveling along the arrangement of the plurality of yarn feeders and of selectively operating the yarn guide member selecting members to advance desired yarn guide members to their yarn feed positions and to retract the advanced yarn guide members from the yarn feed positions to their home positions.

BEST MODE FOR CARRYING OUT THE INVENTION A yarn feeder in a preferred embodiment according to the present invention for a circular knitting machine will be described in connection with the accompanying drawings. The circular knitting machine is provided with a yarn feed system including a plurality of yarn feeders 1. Referring to Fig. 1 showing one of the yarn feeders 1, the yarn feeder 1 is disposed above a cylinder 3 provided with a plurality of needles 2. There is no limit to the number of the yarn feeders 1. Desirably, the plurality of yarn feeders 1 are arranged at equal angular intervals. The yarn feeder 1 has a selector lever guide member 6 provided with a plurality of grooves 5, a plurality of selector levers 4 fitted in the grooves 5, a pair of side plates 7 attached to the opposite side surfaces of the selector lever guide member 6, a rod 8 extended between upper parts of the side plates 7, and an arm 9. The rod 8 and the arm 9 suspend the side plates 7 from an annular member 10 included in the frame of the circular knitting machine. A rod 11 is extended between the inner ends of the side plates 7. An adjust screw 12 extending down from the arm 9 is connected to the rod 11. The adjust screw 12 is operated to set the yarn feeder in a horizontal position. The selector levers 4 fitted in the selector grooves 5 are supported for turning on a rod 15 extended between the side plates 7. Each of the selector levers 4 is provided on its upper edge with a plurality of selector butts 16. All the selector buttes 16 excluding a predetermined selector butt 16 are cut away such that the selector levers 4, the six selector levers 4 in this embodiment, fitted in the guide grooves 5 of the selector guide member 6 are provided with the selector butts 16 at different positions on their upper edges, respectively. Each of the selector levers 4 fitted in the guide grooves 5 of the selector guide member 6 is bent in an inverted V shape. A middle projection 19 project downward from a bent middle part of the selector leer 4. An upper butt 18 formed on a yarn guide arm 17 comes into contact with the middle projection 19. A pin 20 projects from a side surface of the selector lever 4. A spring retaining rod 21 is extended between the side plates 7. A spring 22 supported on the rod 15 has one end retained by the pin 20 and the other end retained by the spring retaining rod 21. The spring 22 urges the selector lever 4 counterclockwise, as viewed in Fig. 1, so that the selector butt 16 projects upward. An actuator 25 is disposed above the selector butt 16. The actuator 25 is supported on an arm radially projecting fro a rotational center shaft that rotates in synchronism with a drive unit included in a cam mechanism for controlling the needles 2. The operation of the actuator is perfectly synchronized with the operation of the needles. The actuator 25 has swing fingers 26, six swing fingers 26 in this embodiment, respectively corresponding to the selector levers 4. The swing fingers 26 are able to engage with the butts 16 of the corresponding selector levers 4, respectively. When any control signal is not given to the actuator 25, all the swing fingers 26 are inclined such that the tips thereof are at left end positions, respectively, as shown in Fig. 1. If a control signal specifying one of the six swing fingers 26 is given to the actuator 25, the specified swing finger 26 is turned to the right, as viewed in Fig. 1, to depress the butt 16 of the corresponding selector lever 4. The yarn guide arms 17 combined respectively with the selector levers 4 are disposed under the selector levers 4 and are supported on guide rods 27 and 28 extended between the side plates 7. The guide rod 27 is engaged in substantially M-shaped guide slots 29 respectively formed in base parts of the yarn guide arms 17, and the guide rod 28 is engaged in substantially V-shaped guide slots 30 respectively formed in middle parts of the yarn guide arms 17. The yarn guide arms 17 are laterally slidable, as viewed in Fig. 1, relative to the guide rods 27 and 28. One end of a spring 32 supported on spring support rods 31 and 31 is in contact with the lower edge of each yarn guide arm 17 to urge the yarn guide arm 17 upward. Each yarn guide arm 17 has positioning recesses 33 and 34, an upper recess 35, and a lower butt 36. An advancing cam 51 and a return cam 52 are arranged under a circular path along which the yarn feeders 1 travel. When the lower butt 36 of the yarn guide member 17 is projected downward, the lower butt 36 is able to engage with the advancing cam 51 and the return cam 52. A locking mechanism 40 is interposed between the selector lever 4 and the yarn guide arm 17. The locking mechanism 40 has locking members 43 and 44 supported for turning on a pair of support shafts 41 and 42, respectively. The locking members 43 and 44 are mirror-image members and are symmetrically arranged. Each of the locking members 43 and 44 has a nose 45 and a flat end 46. A spring 47 has one end connected to an end part of the locking member 43 and the other end connected to an end part of the locking member 44. The spring 47 pulls the locking members 43 and 44 toward each other so that either the nose 45 or the flat end 46 of each of the locking members 43 and 44 is in contact with the yarn guide arm 17. Indicated at 48 and 49 are stoppers. A cutter is combined with each yarn guide arm 17. The cutter has a stationary blade 60, a movable blade 61 and a yarn holding plate 62 shown inirg. 8. The stationary blade 60, the movable blade 61 and the yarn holding plate 62 are flat. The stationary blade 60, the movable blade 61 and the yarn holding plate 62 are superposed such that the movable blade 61 is held between the stationary blade 60 and the yarn holding plate 62. The assembly of the stationary blade 60, the movable blade 61 and the yarn holding plate 62 thus formed is disposed contiguously with one side of the yarn guide arm 17. Hooks 63, 64 and 65 are formed in front end parts of the stationary blade 60, the movable blade 61 and the yarn holding plate 62, respectively. A cutting edge 63a is formed on the outer side surface of the hook 63, and a cutting edge 64a is formed on the inner side surface of the hook 64. The stationary blade 60 and the yarn holding plate 62 are supported on rods 66, 67 and 68 extended between the side plates 7, and the guide rods 27 and 28. The movable blade 61 is provided with laterally spaced slots 69 and 70. The guide rods 27 and 28 are engaged in the slots 69 and 70 such that the movable blade 61 is laterally movable on the guide rods 27 and 28. A pin 71 is attached to the movable blade 61. The pin 71 lies in the upper recess 35 of the yarn guide arm 17. When the yarn guide arm 17 is moved to the right/"as*"vTSWfed in Fig. 1, a back side wall 35a of the upper recess 35 engages with the pin 71 to move the movable blade 61 to the right. The operation of the yarn feeder of the present invention will be described. While the yarn feeder 1 is inoperative, the ^Piprt-^r leygrg A pushed upward by the springs 22 and the butts 16 are held at their upper positions, respectively, as shown in Fig. 1. The yarn guide arms 17 are retracted to their back positions, and are pushed upward by the springs 32 so that the lower butts 36 are retracted into the yarn feeder 1. The actuator 25 travels along the circular arrangement of the plurality of yarn feeders 1. When the actuator 25 comes into engagement with the yarn feeder 1 and one of the yarns to be fed by the yarn feeder 1 is to be fed, the swing finger 26 of the actuator 25 corresponding to the butt 16 of the selector lever 4 corresponding to the yarn guide arm 17 for guiding the selected yarn is turned to depress butt 16. Consequently, the selector lever 4 is turned clockwise, as viewed in Fig, 1, to move a back end 4a downward, the back end 4a come into contact with and depresses the upper butt 18 of the yarn guide arm 17 to turn the yarn feed arm 17 against the resilience of the spring 32, so that the lower butt 36 projects downward from the yarn feeder 1 into the path of the advancing cam 51 as shown in Fig. 2. The locking mechanism 40 holds the back end 4a of the selector lever 4 in contact with the upper butt 18 of the yarn guide arm 17 as shown in Fig. 2; that is, the locking mechanism 40 holds the lower butt 36 of the yarn guide arm 16 in the path of the advancing cam 5T*in a period immediately before a time point when the yarn guide arm 17 starts advancing to the yarn feed position. The period immediately before a time point when the yarn guide arm 17 starts advancing to the yarn feed position is a time period immediately before a time point when the yarn guide arm 17 starts advancing to the yarn feed position. Thus, the locking mechanism 40 holds the lower butt 36 of the yarn guide arm 17 in the path of the advancing cam 51 for the period immediately before the time point when the yam guide arm 17 starts advancing toward the yarn feed position. Therefore, though the actuator 25 operates for only a short time, the proper motional relation between the lower butt 36 of the yarn guide arm 17 and the advancing cam 51 can be ensured. Consequently, the engagement of the lower butt 36 of the yarn guide arm 17 and the advancing cam 51 can be correctly timed. While the lower butt 36 of the yarn guide arm 17 is held in the path of the advancing cam 51 by the locking mechanism 40, the lower butt 36 moves along the cam surface 51a of the advancing cam 51, so that the yarn guide arm 17 is shifted to the left, as viewed in Fig. 2, from a position shown in Fig. 2 to a position shown in Fig. 3 where a bottom part of the substantially V-shaped guide slot 30 coincides with the guide rod 28. thus, the yarn guide hole 53 is shifted horizontally and vertically and is moved over the top of the needle 2 held on the cylinder 3. When the lower butt 36 of the yarn guide arm 17 reaches a position near to top of the advancing cam 51, the back side wall 35a of the upper recess 35 of the yarn guide arm 17 comes into contact with the nose 45 of the locking member 44 as shown in Fig. 4 and turns the locking member 44 clockwise. When the lower butt 36 of the yarn guide arm 17 reaches the top of the advancing cam 51, the yarn guide arm 17 guided by the guide rods 27 and 28 reaches a front position, the yarn guide arm 17 is turned counterclockwise, as viewed in Fig. 5, on the guide rod 28 by the resilience of the spring 32. Consequently, the guide rod 27 engages in a rear lower end of the substantially M-shaped guide slot 29, and the lower butt 36 is retracted into the yarn feeder 1. At the same time, the yarn guide hole 53 formed in a front end part of the yarn guide arm 17 is lowered slightly to a yarn feed position to feed the yarn to the needle 2. As the yarn guide arm 17 advances, the pin 71 of the movable blade 61 in contact with the back side wall 35a of the upper recess 35 of the yarn guide arm 17 is pushed forward to advance the movable blade 16. Consequently, the hook 64, having the upward concave U-shaped cutting edge 64a, of the movable blade 61 held between the respective hooks 63 and 65 of the stationary blade 60 and the yarn holding plate 62 protrudes beyond the hooks 63 and 65. The yarn Y does not enter hook 64 having the U-shaped cutting edge 64a while the yarn Y is being fed to the needle and is knitted into a knotted fabric. After a predetermined number of courses of loops of the yarn guide by the yarn guide arm 17 have been knitted, the yarn Y is changed for another yarn. The yarn feeder 1 stops feeding a first yarn and starts feeding a second yarn. Timing of the operation of the actuator 25 is controlled properly such that an operation for stopping the feed of the first yarn and that for starting the feed of the second yarn are achieved simultaneously. However, both the first and the second yarn are fed for some wales. Since the actuator 25 operates in a very short time, the butt 16 of the selector lever 4 is depressed for a short time, and the selector lever 4 returns to its home position immediately. The feed of the first yarn is stopped by the following operation. When the actuator 25 is operated to depress the butt 16 of the selector lever 4 with the swing finger 26 while the first yarn is being fed in a state shown in Fig. 5, the selector lever 4 is turned clockwise, as viewed in Fig. 5, and the middle projection 19 depresses the upper butt 18 of the yarn guide arm 17. Since the actuator 25 is operated for a very short time, the butt 16 of the selector lever 4 is pressed only for a moment and the selector lever 4 is returned to its home position by the resilience of the spring 22. When the upper butt 18 of the yarn guide arm 17 is depressed by the middle projection of the selector lever 4, the yarn guide arm 17 is turned clockwise on the guide rod 28 to release the nose 45 of the locking member 44 from the back side wall 35a of the upper recess 35. Then, the locking member 44 is turned counterclockwise by the spring 47, and the flat 46 of the locking member 44 comes into contact with the shoulder 18a of the upper pad 18. Consequently, the yarn guide arm 17 is held at a yarn feed position against the resilience of the spring 32 with the lower butt 36 thereof projected down from the yarn feeder 1. Thus, the yarn guide arm 17 guiding the first yarn is turned clockwise on the guide rod 28 and the lower butt 36 of the yarn guide arm 17 projects from the yarn feeder 1 as shown in Fig. 6. As shown in Fig. 6, the locking mechanism 40 holds the yarn guide arm 17 at the yarn feed position with the lower butt 36 of the yarn guide arm 17 located on the path of the advancing cam 51 for a period immediately before the yarn guide arm 17 starts moving backward from the yarn feed position. The period immediately before a time point when the yarn guide arm 17 starts retracting from the yarn feed position is a time period including a time point immediately before the yarn guide arm 17 starts retracting from the yarn feed position. Since the locking mechanism 40 holds the yarn guide arm 17 at the yarn feed position with the lower butt 36 of the yarn guide arm 17 located on the path of the advancing cam 51 for a period immediately before the yarn guide arm 17 starts moving backward from the yarn feed position, the proper motional relation between the lower butt 36 of the yarn guide arm 17 and the advancing cam 51 can be ensured. Consequently, the engagement of the lower butt 36 of the yarn guide arm 17 and the advancing cam 51 can be properly timed. Then, the lower butt 36a of the yarn guide arm 17 guiding the first yarn comes into engagement with a return cam 52. The return cam 52 starts moving the yarn guide arm 17 backward, then, shoulder 18a of the upper butt 18 moves to the right, as viewed in Fig. 6, the shoulder 18a is released from the nose 45 and the flat end 46 f the locking member 44 and thereby the yarn guide member is unlocked. Since the guide rod 27 is engaged in the M-shaped guide slot 29, the lower butt 36 of the yarn guide arm 17 is kept projected down from the yarn feeder 1 until the yarn guide arm 17 is moved backward to a position where the guide rod 27 engages in a front recess 29a at the front end of the M-shaped guide slot 29. When the butt 36a is disengaged from the return cam 52, the yarn guide arm 17 is turned counterclockwise on the guide rod 28 by the resilience of the spring 32. Consequently, the positioning recess 34 is raised, the guide rod 27 engages in the front recess 29a of the M-shaped guide slqt 29, the back end of the yarn guide arm 17 turns upward, and the lower butt 36a is retracted into the yarn feeder 1 as shown in Fig. 1. When the yarn guide member 17 is retracted, a front side wall 35b of the recess 35 of the yarn guide arm 17 comes into contact with the pin 71 of the movable blade 61 in a state where its hook 64 is protruded beyond the stationary blade 60 and the yarn holding plate 62, to retract the movable blade 61 as the yarn guide arm 17 is retracted. At time when the yarn guide arm 17 reaches a position where the front side wall 35b of the yarn guide arm 17 engages with the pin 71 of the movable blade 61, the yarn guide hole 53 of the yarn guide arm 17 coincides with the hook 64 of the movable blade 61, and the first yarn threaded through the yarn guide hole 53 is guided into the hook 64. As the yarn guide arm 17 is retracted further, the movable blade 61 is moved backward. Consequently, the first yarn is cut with the respective cutting edges 63a and 64a of the stationary blade 60 and the movable blade 61 and, at the same time, an end part of the first yarn is held between the respective hooks 64 and 65 of the movable blade 61 and the yarn holding plate 62. Condition where both the first and the second yarn are knitted simultaneously for several wales will be described. Even though lower butt 36 of the yarn guide arm 17 guiding the second yarn and lower butt 36a of the yarn guide arm 17 guiding the first yarn are protruded from the yarn feeder 1 by simultaneously actuating the swing fingers 26 of the actuator 25 for operating the selector levers 4 for selecting the yarn guide arms 17 respectively guiding t^ie first and the second yam, the advancing cam 51 precedent to the return cam 52 with respect to the rotating direction of the knitting machine engages first with the lower butt 36 of the yarn guide arm 17 guiding the second yarn to advance the lower butt 36 along the cam surface 51a, and the lower butt 36 is retracted into the yarn feeder 1 upon the arrival of the lower bujtt 36 at the top of the advancing cam 51 and hence the lower butt 36 does not engage with the return cam 52 disposed behind the advancing cam 51. Subsequently, the return cam 52 engages with the lower butt 36a of the yarn guide arm 17 guiding the first yarn. Thus, both the first and the second yarn are fed for a period corresponding to a distance L shown in Fig. 7. The yarn feeder of the present invention transmits the instant motion of the actuator, i.e., a selecting device, through the locking mechanism to the locked yarn guide arm. Therefore, the yarn guide arms are operated accurately and do not move irregularly, and hence the occurrence of troubles during the operation of the knitting machine can be prevented. Since the movable blade of the cutter is driven directly by the yarn guide arm, the yarn guiding motions and the yarn cutting motions are synchronized perfectly, and any additional mechanism for operating the cutter is not necessary. Since the locking mechanism securely holds the yarn guide arm selected by the selector lever operated by the actuator and advanced to a yarn feed position so that the lower butt of the yarn guide arm is located on the path of the advancing cam at the yarn feed position, the yarn guide arm selected by the instant motion of the actuator can be kept in a selected state after the completion of the operation of the actuator. The selected yarn guide arm can be kept in the selected state both when the feed of the yarn through the selected yarn guide arm is stopped and when the feed of another yarn through another selected yarn guide arm is started. The yarn feed system of the present invention includes the single selector operating device, such as the actuator, and the selector operating device can travel along the arrangement of the plurality of yarn feeders. Thus, the yarn feed system needs the single selector operating device regardless of the number of the yarn feeders. * The use of the single selector operating device simplifies the construction of the knitting machine and facilitates maintenance work. Since the movable blade of the cutter is interlocked with the yarn guide member such that the movable blade is moved by the yarn guide member to cut the yarn when the yarn guide member retracts from the yarn feed position, any special mechanism for moving the movable blade is not necessary.
