In this torsion race machine, a shifter that is fitted to a fork shaft is known. As a driving means for causing the fork to move up and down, a cam is fitted to a driven gear shaft fitted to a rotating shaft of a spindle plate for rotating a spindle on which a bobbin is fitted, and the displacement of the cam is determined. There is a structure in which a drive lever for generating a driving force is provided by using, for example, disclosed in Japanese Utility Model Publication Nos. 60-28702 and 61-38941.
In the one disclosed in Japanese Utility Model Publication No. 60-28702, a selection rod is pivotally supported at the lower part of the fork shaft, and the selection rod is connected to a plunger of a solenoid fixed to the machine frame. Further, what is disclosed in Japanese Utility Model Publication No. 61-38941 is that a plurality of levers utilizing the displacement of the cam rotate a shaft in which the selection rod is slidably fitted, and protrudes from the shaft. The control rod to be rotated is simultaneously turned and brought close to the magnet coil, and then can be selected by being attracted to the magnet coil or not attracted.
In addition, there is also known one that employs a selection rod utilizing the rotation of the shaft of the rotary solenoid between the fork shaft and the driving force transmission end of the drive lever opposite to the cam acting side.
However, with respect to the devices described in the above publications, in the configuration of these selection devices, the control rod collides with or strongly abuts against the magnet when the selection rod acts on the fork shaft or does not operate. Therefore, the occurrence of collision during operation and strong contact resistance may cause malfunction, resulting in lack of follow-up performance at the time of high-speed braiding, and problems such as coil breakage and other problems. There was a risk of hindrance. In addition, since each apparatus has a large number of parts and a complicated structure, there are problems that maintenance is not easy and manufacturing cost is high.

In addition, a solenoid is installed close to the selection rod so that it can be magnetically actuated, and when the selection rod is moved to an action or non-operation position on the fork shaft or shifter fork, the solenoid is energized between the permanent magnet and the permanent magnet. The selection pole is moved by generating a repulsive magnetic field of the same polarity, and when the selection pole is not moved, the solenoid is de-energized to control the selection operation.
According to the present invention, the selection operation of the selection rod is performed quickly and accurately by moving it by repulsion with the permanent magnet by energizing the solenoid or by keeping the solenoid in a non-operating state by de-energizing. The
In the above, when the selection rod is not moved, the selection rod can be held so as not to move by generating a different-polarity attractive magnetic field with the permanent magnet by energizing the solenoid. In this case, the selection rod can be reliably held in the non-operating state.
In the above, it is preferable that the selection rod is held in a non-contact state with respect to the member on the solenoid side when the selection rod is moved to the non-operation position by the energization of the solenoid. As a result, malfunction due to collision or strong contact during operation does not occur, and high-speed rotation can be followed without any problem.
Further, it is preferable that the selection rod moved back as described above is returned to the solenoid side by the return means, so that the selection rod can be reliably restored.
In particular, when the return means is a return member acting on the lower part of the selection rod, the return displacement is forcibly generated by the engagement with the inclined surface of the return member.
Furthermore, when the return means is constituted by another solenoid provided with the selection rod interposed therebetween, the followability of the selection rod is further enhanced by the mutual action of the mutual solenoid's suction and repulsion.
The shifter fork drive selection control device according to the present invention includes a lift member provided in the axial direction of a fork shaft to which a reciprocating shifter fork is attached, and a lift member fixed to the machine frame and slidably held.

It is characterized by being made.
According to the device of the present invention, the actuator can be operated to engage the shifter fork or the engaging part of the fork shaft, or to hold the shifter fork in the disengaged position so that the shifter fork can be driven up and down easily. can do.
In the above-described apparatus, it is particularly preferable that the actuator is based on the interaction between a permanent magnet attached to the pole and a solenoid provided so as to be able to act appropriately on the permanent magnet.
In this case, due to the repulsive force caused by energization of the solenoid of the actuator, the pawl is engaged with the engaging portion of the shifter fork or the fork shaft, and when not energized, the attracting force of the permanent magnet fitted to the pawl or the actuator is used. By the suction force of the solenoid, the pawl can be securely held in the non-engaged position, and the shifter fork can be driven up and down without causing a malfunction. Thereby, the said method can be implemented favorably.

Solenoids 21a and 21b as actuators, and pawls 23a and 23b as selection rods supported by the support shafts 28a and 28b so as to be able to tilt up and down in the elevating member 20, respectively, and the solenoids There are permanent magnets 22a and 22b fitted on the opposite sides of the pawls 23a and 23b to the solenoid so that they can be magnetically acted on by 21a and 21b. The permanent magnets 22a and 22b are arranged so that the magnetic poles and NS poles when energized when the solenoids 21a and 21b opposing the poles are moved are the same polarity. As the solenoids 21a and 21b, those having an iron core are usually used.
Furthermore, a substantially L-shaped displacement imparting member 24 arranged so as to be in constant contact with the bottom surface 20b1 of the elevating member 20, and a displacement imparting member fixed to the machine frame 1 via a bearing (not shown) and a fulcrum pin 27a. A support member 25 that rotatably supports the member 24 is provided.
Here, regarding the energization of the solenoids 21a and 21b, the solenoid is connected to a control unit (not shown) by an electric wire, but besides this, an induced power is separately supplied to the solenoid and a control signal is supplied. It is also possible to adopt a configuration in which the electric wires are excluded by supplying the wirelessly to the receiving unit.
The elevating member upper portion 20a and the elevating member lower portion 20b of the elevating member 20 indicated by hatching are perforated at the center so that the fork shaft 14 can slide, and the hole 30 of the elevating member lower portion 20b is formed by the elevating member. No matter what ascending or descending state 20, the fork shaft 14 is not affected.
A rod end 26 is connected to the displacement imparting member 24 at its lower end so as to be rotatable via a bearing (not shown) and a fulcrum pin 27 b, and is screwed to the rod end 26. When the shifter fork drive displacement transmission member 29 is pulled in the direction of arrow A, the displacement applying member 24 rotates to push up the lifting member 20 in the direction of arrow B.
The shifter fork drive displacement transmission member 29 is configured to be reciprocated in the direction of arrow A in FIG. 1 in synchronization with the rotation of a main shaft (not shown) of a torsion race machine, for example.
In the drive selection control device 18 having the above-described configuration, when the solenoids 21a and 21b are not energized, the permanent magnets 22a and 22b pass through the elongated holes 32 formed in the side surfaces of the elevating member 20, respectively. , 21b tries to be attracted to the iron core, but is held in a state of being close to the solenoids 21a, 21b by being blocked by the protrusions 20a1, 20a2 of the upper and lower members 20a (the state shown in FIGS. 1 and 2). ) Since the pawls 23a and 23b are lifted without acting on the fork shaft 14, the fork shaft 14 remains stationary.
Further, when the solenoids 21a and 21b are energized, the solenoids 21a and 21b are magnetized so as to have the same polarity as the NS poles of the permanent magnets 22a and 22b facing the solenoids 21a and 21b, and the same-polar repulsive magnetic field with the permanent magnets. As a result, the pawls 23a and 23b are repelled in the directions of arrows C1 and C2 in FIGS. 1 and 2, so that the engaging portions 23a1 and 23b1 of the pawls 23a and 23b and the notches 14a and 14b which are engaging portions on the fork shaft side are engaged. As the elevating member 20 is raised by the displacement applying member 24, the engaging portions 23a1, 23b1 and the notches 14a, 14b are engaged with each other to lift the fork shaft 14.
As a result, the shifter fork 11 fitted to the fork shaft 14 rises together with the fork shaft 14, and the upper fork 12 and the lower fork 13 fixed to the shifter fork 11 also follow it. The clutch P, which is rotatably held by the circumferential groove 5a, can be engaged with a clutch engaging member 10 formed integrally with the spindle plate 4 at a position P.A. Displacement to D.
In this state, when the drive gear 6 rotates, the clutch 5 performs additional rotation, and the rotational force is transmitted to the spindle plate 4 via the clutch engaging member 10.
In the above, the engagement / non-engagement selection control of the pawl to the shifter fork or the engagement portion on the fork shaft side is performed by a combination of a permanent magnet and a solenoid. Needless to say, the amount of displacement can be selected and controlled directly or indirectly through a lever or the like.
Next, a second embodiment of the shift fork drive selection control method and apparatus according to the present invention will be described with reference to FIG. The same members and structures as those of the first embodiment, such as the spindle driving member 3, are denoted by the same reference numerals.
In FIG. 4, reference numeral 141 denotes a fork shaft, which is fitted with a shifter fork 11 and an engaged collar 54 as an engaging portion that is in contact with the shifter fork 11 and is screwed to the machine frame 1. The holding member 191 is slidably fitted to the elevating member upper portion 202a held slidably. A compression spring 16 is positioned between the upper machine casing 2 and the shifter fork 11 at both ends by receiving seats 17a and 17b, and is loosely fitted to the fork shaft 141 so as to urge the shifter fork 11 downward.
Reference numeral 181 denotes a shifter fork drive selection control device of the second embodiment, which has the following configuration.
A holding member 191 fixed to the machine frame 1 by screwing means or the like, an elevating member 202 slidably held in the holding member 191, and a support shaft 281 at a notch portion of the elevating member upper portion 202a.

A non-magnetic L-shaped member 53 screwed to the machine casing 1 and a solenoid as an actuator fixed to the L-shaped member 53 so as to be able to act magnetically facing the permanent magnet 221. 212. The solenoid 212 is set so that the magnetic pole of electromagnetic transmission during the movement of the pole is the same as the NS pole of the permanent magnet 221.
The hole 300 drilled in the center of the upper and lower member upper portion 202a is bent so as not to be affected by the fork shaft 141 regardless of the lift member 202 being lifted or lowered.
The cam 46 is provided so as to rotate following the tubular shaft 9, and when the convex portion of the peripheral surface reaches the contact surface with the transmission roller 47, the transmission roller 47 is pressed in the direction of the arrow A 2, and the displacement applying member 241 is configured to displace the displacement imparting 202 in the direction of the arrow B2.
In the drive selection control device 181 of this embodiment, when the solenoid 212 is not energized, when the elevating member 202 is lowered, the lower right end 231a1 of the pawl 231 is the inner surface of the notch groove 191a of the holding member 191 as a return means. At the same time, the permanent magnet 221 tries to attract the iron core of the solenoid 212 at the same time as the permanent magnet 221 reaches the position close to the solenoid 212. The lower left end 231a2 of the lower end of the pawl 231 comes into contact with the inclined surface 202a1 of the cutout portion of the upper part 202a of the elevating member 202a, and further tilting of the pawl 231 is prevented, and the pawl 231 is close to the L-shaped member 53. Keep position. In this state, the pawl 231 becomes inactive with respect to the engaged collar 54 as the engaging portion fitted to the fork shaft 141, and rises without acting on the fork shaft 141 as it is. Stay stationary.
When the solenoid 212 is energized, the solenoid 212 is magnetized so as to have the same polarity as the NS pole of the permanent magnet 221 and a repulsive magnetic field is generated, thereby repelling the pole 231 in the direction of the arrow C4. Then, the pawl 231 becomes operable on the engaged collar 54 fitted to the fork shaft 141, and the fork shaft 141 is engaged with the engaged collar 54 as the elevating member 202 is raised by the displacement applying member 241. lift.
Thus, as in the first embodiment, the shifter fork 11 fitted to the fork shaft 141 displaces the clutch 5 to a position where it can engage with the clutch engaging member 10, and the drive gear 6 rotates in this state. Then, the rotational force is transmitted to the spindle plate 4 via the clutch engaging member 10.
5 and 6 show a third embodiment of a shifter fork drive selection control method and apparatus according to the present invention. Also in this embodiment, the same members and structures as those of the first embodiment such as the spindle driving member 3 are denoted by the same reference numerals.
In FIG. 5, reference numeral 143 denotes a fork shaft which is fitted with a shifter fork 11 and is slidably fitted to an upper portion 193a of a holding member 193 fixed to the machine frame 1 by screwing means or the like. A compression spring 16 is positioned between the upper machine casing 2 and the shifter fork 11 by receiving seats 17a and 17b, and is loosely fitted to the fork shaft 143 so as to urge the shifter fork 11 downward.
Reference numeral 183 denotes a shifter fork drive selection control device according to the third embodiment, which has the following configuration.
In the holding member 193 fixed to the machine frame 1, the elevating member 204 is slidably held up and down. Further, as shown in FIG. It is inserted into the groove portion 57 squeezed to the depth of the bottom 204 a and the groove portion 60 squeezed at the bottom portion of the holding member 193, and is fixed to the holding member 193 by the snap ring 58. In the groove portion 57 of the elevating member 204, a pawl 233 as a selection rod is pivotally supported by a support shaft 283 so as to be able to be tilted and a permanent magnet 223 is provided on the pawl 233.
A compression spring 164 is disposed between the seat 61 provided at the lower end of the elevating member 204 and the stepped portion of the holding member 193 so that the elevating member 204 is inserted, and the elevating member 204 is attached downward. It is fast. The roller 274 that contacts the elevating member bottom surface 204b is rotatably attached to the displacement applying member 242 via a fulcrum pin 273b, and the displacement applying member 242 is provided rotatably via the fulcrum pin 273a. A transmission roller 470 is connected to the member 242.
The cam 46 is fitted to the tubular shaft 9, and its peripheral surface is in contact with the transmission roller 470. The solenoid member 56 fixed to the holding member 193 by screwing means or the like has a solenoid 214 provided so as to face the permanent magnet 223 so as to be magnetically operable. The solenoid 214 is set so that the magnetic pole when energized during the movement of the pole is the same pole as the permanent magnet 223 and the NS pole.
The stopper pin 53 is attached to the groove portion 57 of the elevating member 204 so as to keep the pawl 233 at an appropriate position when the pawl 233 is repelled by the solenoid 214. Needless to say, a stopper means such as a projecting piece that performs the same function may be provided in place of the stopper pin.
The cam piece 54 is provided so as not to be affected by the elevating / lowering member middle bottom 204a regardless of the rising / lowering state of the elevating / lowering member 204.
In the drive selection control device of this embodiment, the cam 46 is rotated around the tubular shaft 9, and when the convex portion of the peripheral surface reaches the contact surface with the transmission roller 470, the transmission roller 470 presses in the direction of the arrow A5. Then, the displacement applying member 242 displaces the elevating member 204 in the direction of the arrow B4.
When the solenoid 214 is not energized, when the elevating member 204 is lowered, the bottom of the pawl 233 comes into contact with the inclined surface 54a of the cam piece 54 as a return means, and the force that tilts the pawl 233 toward the solenoid 214 is obtained. At the same time, the permanent magnet 223 also tries to be attracted to the iron core of the solenoid 214. With the permanent magnet 223 reaching the position close to the solenoid 214, the central portion of the pole 233 is connected to a part 193b of the holding member 193. As a result, the pawl 233 keeps the proximity position with respect to the solenoid 214. In this state, the tip (upper end) of the pawl 233 moves up without acting on the lower end as the engaging portion of the fork shaft 143, so that the fork shaft 143 is held stationary.
When the solenoid 214 is energized, the solenoid 214 is magnetized so as to have the same polarity as the NS pole of the permanent magnet 223 facing the solenoid 214 to generate a repulsive magnetic field, and the pole 233 is moved to the arrow C6. Therefore, the pawl 233 is rotated to a position where it abuts against the stopper pin 53, and can be acted on the fork shaft 143. As the elevating member 204 is lifted by the displacement applying member 242, the fork shaft 143 is lifted up. .
As a result, the shifter fork 11 displaces the clutch 5 to a position where it can engage with the clutch engaging member 10, and the drive gear 6 rotates in this state, so that the rotational force is transmitted via the clutch engaging member 10 to the spindle plate. 4 is transmitted.
Further, as a means for holding the pawl 233 at a position close to the solenoid 214 when the solenoid 214 is not energized, a bush is fitted on the outer periphery of the elevating member 204 to cover the groove portion 57 of the elevating member 204 or a part of the groove portion 57 is covered. It is possible to prevent the pawl 233 from coming into contact with the holding member 193 by closing or by fitting a stopper ring to the upper inner periphery of the groove portion 57.
In each of the first to third embodiments described above, when the pawls 23a, 23b, 231 and 233 which are the selection rods are not moved, that is, when they are close to the solenoids 21a, 21b, 212 and 214, It is also possible to energize the solenoid so as to generate a permanent magnetic field with the permanent magnets 22a, 22b, 221, and 223, and hold the pole so as not to move by the attraction action. In this case, the pawl is more reliably held in the inoperative state. When the solenoid does not have an iron core, it can be held in a non-operating state by means other than a permanent magnet.
Further, as a return means for returning the moved and displaced selection pole to the solenoid side, the magnetic force of the permanent magnet is used in the first embodiment, and the lifting member is used in the second embodiment or the third embodiment. A part of the holding member with which the lower end of the pawl abuts or the inclined surface of the cam piece is used as the inclined surface of the return member. It is also possible to use a separate solenoid provided across the selection rod to perform the return action.
In FIG. 7, a pole 235 as a selection rod is provided on a lifting / lowering means (not shown) that can be moved up and down in the direction of the arrow B5 in the drawing by a suitable displacement applying means. The fork shaft 145 is engaged with the fork shaft 145 by a tilting action, and a permanent magnet 225 is provided on the pawl 235. Two solenoids 215a and 215b are arranged with the pawl 235 interposed therebetween, and the magnetic poles when energized during the pawl movement are set so that the permanent magnet 225 and the NS pole facing each other have the same polarity.
In the non-operating state of the pawl 235 with respect to the fork shaft 145 (the state shown in FIG. 7), the solenoid 215a and 215b are not energized and are tilted and approached to the solenoid 215a side by the attractive action of the permanent magnet 225. Hold. Further, when the pawl 235 is moved to the working position with respect to the fork shaft 145, the solenoid 215a is energized to become magnetized so as to have the same polarity as the NS pole of the opposing permanent magnet 225, and the same polarity is provided between the permanent magnet and the permanent magnet. A repulsive magnetic field is generated, the pawl 235 is moved to a position where it is engaged with the fork shaft 145, and the state is maintained by the magnetic force of the permanent magnet 225 in proximity to the solenoid 215b.
Further, when returning the pawl 235 to the non-operating position, an energizing repulsive magnetic field is generated in the permanent magnet 225 by energizing the solenoid 215b to tilt the pawl 235 toward the solenoid 215a.
In order to maintain the non-acting state or the working state due to the tilting of the pawl 235, it is possible to generate a different-polarity attracting magnetic field for the permanent magnet in the solenoid 215a or 215b.
In FIG. 7, 65 a and 65 b indicate that the pawl 235 is connected to the solenoid 215 a. It is a stopper that restricts the movement of the pawl 235 beyond a certain level in order to hold it at a position close to 215b.
In the above torsion lace machine, it is possible to adopt a group management system that collects a plurality of lace machines together by a central control unit and centrally manages the braided state, thereby enabling more efficient production management of torsion lace machines. Is possible.
