Description

  The present invention relates to a torsion race machine that can stably rotate a cam wheel that slides a horizontal shaft that rotates a rotor metal that moves a spindle runner (bobbin spindle) to the right or left.

  In a conventional torsion race machine, a spindle runner is interposed between recesses of a rotor metal arranged on the same circle, and one rotor metal rotates 180 ° in the recesses facing each other adjacent to the left and right of the rotor runner. Are moved one step at a time.

  When moving the spindle runner several steps continuously, as shown in FIG. 8, one spindle runner S located at a position of the broken line trajectory (rotation of the rotor metal A 180 degrees to the right as shown by the arrow ( Inward) Move one step through A 'to reach position b. In this case, the spindle runner S ′ originally located at the position “b” moves so as to be replaced with the position “a”.

  Next, when the rotor metal B rotates 180 ° to the left as shown by the arrow, the spindle runner S (shown as S ′ in the drawing) takes one step from the position b through a broken line trajectory (outward turn) B ′. Move to position c. Subsequently, when the rotor metal C is rotated 180 ° to the right as shown by an arrow, it is sequentially repeated so as to move one step from the position c through the broken line locus (inner direction) C ′ to the position d.

  In the above-described conventional torsion race machine, the rotation of one rotor metal from right to left is performed by setting a horizontal axis that fixes two bevel gears opposed to each other with a bevel gear rotating integrally with the rotor metal. The left and right cam surfaces of the cam ring fixed to the outer end portion of the cam are selectively brought into contact with the plunger that protrudes and retracts by operating two solenoids and slid to the left and right, and one of the two bevel gears is an umbrella integrated with the rotor metal. This was realized by meshing with a gear.

  The cam wheel having the left and right cam surfaces that come into contact with the plungers protruding and retracting by the two solenoids has side walls that guide the traveling body on the left and right. The width of the side wall is kept wide within an angle where one of the two bevel gears meshes with the bevel gear rotating integrally with the rotor metal, and is narrowed and narrowed outside this angle. It was comprised so that a traveling body could always drive | work the center part of a side wall.

  However, the rotor metal that runs the spindle runner equipped with the handle yarn bobbin is also stopped, and there are two bevel gears facing each other with the bevel gear rotating integrally with the rotor metal even in this time zone. The horizontal shaft that is fixed is kept rotating while keeping the two bevel gears in a neutral position, so that it can respond immediately when there is an instruction to supply the handle yarn. The traveling body between the side walls of the cam ring fixed to the outer shaft end of the horizontal shaft in the neutral position may be shaken in the width direction between the wide side walls. Even if the blur is corrected at the narrow portion of the side wall as described above, there is a problem that the correction becomes insufficient when the rotational speed is increased, and the rotor metal cannot be rotated according to the structure.

  In the present invention, in view of the above points, when the solenoid slides on the left and right cam surfaces of the cam wheel in which the horizontal shaft at the neutral position is fixed to the outer end in the time period when the rotation of the rotor metal is stopped. Another object of the present invention is to provide a torsion race machine in which the rotor metal can be rotated according to the organization so that the traveling body traveling between the side walls can stably travel even when the solenoid does not act and does not slide. It is said.

  In order to achieve the above object, a torsion racing machine according to the present invention is a bevel gear that rotates integrally with a rotor metal that is fitted to a fixed vertical shaft that is annularly arranged at a predetermined interval on a base so as to be rotatable in the horizontal direction. A horizontal shaft with two bevel gears fixed to each other is provided, a cam ring having cam surfaces formed on the outer surfaces of the left and right side walls is fixed to the outer end of the horizontal shaft, and plungers are mounted on the left and right cam surfaces of the cam wheel. Two solenoids that are selectively brought into contact with each other, and a recess groove provided endlessly along the circumference between the side walls of the cam ring so that it can escape against the spring pressure of the spring when the cam ring slides. The traveling body is inserted into the body, and the traveling body can stably travel even when the cam wheel is slid left and right.

  Further, in the torsion race machine according to the second aspect of the present invention, the groove between the side walls of the cam ring has a tapered surface that expands outward, and the cam ring is activated by actuation of a solenoid. When the vehicle slides, the traveling body can be easily escaped from the concave groove.

  Furthermore, the torsion race machine according to the invention of claim 3 is characterized in that the lower edge portion of the traveling body is a tapered surface having a smaller diameter toward the lower surface, and the cam wheel is activated by the operation of the solenoid. It was configured so that the traveling body could easily escape from the concave groove when sliding.

  According to the present invention, the cam ring having cam surfaces formed on the outer surfaces of the left and right side walls is fixed to the outer end of the horizontal shaft that fixes the two bevel gears with the bevel gear rotating integrally with the rotor metal. Two solenoids for selectively contacting the plunger are provided on the left and right cam surfaces of the cam ring, and a spring is provided in a concave groove provided endlessly along the circumference between the side walls of the cam ring when the cam ring slides. Since the traveling body is fitted so that it can escape against the spring pressure, the traveling body can stably travel when the cam wheel is not slid, and the traveling body is in a neutral position without interfering with the slide. This produces an excellent effect that the blur in the axial direction of the horizontal axis can be surely eliminated.

  According to the second aspect of the present invention, since the concave groove between the side walls of the cam ring is a tapered surface that expands outward, the travel when the cam ring slides due to the operation of the solenoid. It has an excellent effect that it is easier to escape from the body.

  Furthermore, according to the invention described in claim 3, since the lower edge portion of the traveling body is a tapered surface having a smaller diameter toward the lower surface, the cam wheel is slid by the operation of the solenoid. This has an excellent effect that the running body can be easily escaped.

  Next, an embodiment of the present invention will be described with reference to FIGS. 1 is a side cross-sectional view of a rotor metal drive mechanism including the main part of the present application, FIG. 2 is an enlarged cross-sectional view of the main part of the present application, FIG. 3 is an enlarged cross-sectional view of a traveling body and a groove, and FIG. 5 is a front view of the cam wheel, FIG. 6 is a bottom view of the cam wheel, and FIG. 7 is a perspective view showing a main part of the present application and its peripheral mechanism.

  Two bevel gears sandwiching a bevel gear 4 that rotates integrally with a rotor metal 3 that is rotatably fitted in a horizontal direction on a fixed vertical shaft 2 that is annularly arranged at predetermined intervals along the outer periphery of the base 1 A horizontal shaft 6 to which 5 and 5 'are fixed is provided. The horizontal shaft 6 has a cam ring 7 fixed to an outer end portion thereof via a key 6 '(see FIG. 2), and a slide connecting portion (sliding freely in the axial direction and rotating in an axial direction). The bevel gear 9 is fixed via 8).

  The bevel gear 9 is meshed with a bevel gear 12 that rotates integrally with a spur gear 11 that meshes with the drive gear (large spur gear) 10 that rotates in conjunction with a main shaft (drive unit) (not shown). Therefore, the bevel gear 12 that rotates integrally with the spur gear 11 that rotates continuously from the drive gear 10 rotates the horizontal shaft 6 via the bevel gear 9. The bevel gear 12 and the spur gear 11 share a rotating shaft 13.

  The cam wheel 7 fixed to the outer end portion of the horizontal shaft 6 raises substantially semicircular side walls 14 and 14 'on the left and right, and the outer surfaces of the side walls are cam surfaces 15a and 15a'. The left and right cam surfaces 15a and 15a 'are brought into contact with the tip rollers 16 "and 17" of the plungers 16' and 17 'protruding by selectively energizing the two solenoids 16 and 17, respectively. That is, when the plunger 16 'of the left solenoid 16 protrudes and the tip roller 16' 'acts on the left cam surface 15a of the cam wheel 7, the cam wheel 7 slides to the right together with the horizontal shaft 6. On the other hand, When the plunger 17 ′ of the solenoid 17 protrudes and the tip roller 17 ″ acts on the right cam surface 15 a ′ of the cam ring 7, the cam ring 7 slides to the left together with the horizontal shaft 6.

  When the horizontal shaft 6 slides as described above, one of the bevel gears 5 and 5 'fixed to the horizontal shaft 6 is engaged with the bevel gear 4 that rotates integrally with the rotor metal 3, and the rotor metal 3 is rotated clockwise or counterclockwise. Rotate to The rotation of the rotor metal 3 is always subjected to a rotation of only 180 ° because the bevel gears 5 and 5 ′ are missing in a range of 180 °. The rotation of the rotor metal 3 causes the spindle runners 18 in the concave portions on both sides of the rotor metal to move so that the left and right are interchanged (see FIG. 8). By this movement, the yarns 20 drawn from the bobbin 19 mounted on the spindle runner 18 are entangled with each other in a lace forming portion (not shown) so as to knit the knitted lace fabric.

  When the rotor metal 3 is rotated by 180 ° by the bevel gears 5 and 5 'having the missing teeth, the rotor metal 3 has claw pieces 21 extending from the hollow shaft 3'. Since the concave groove 25 formed on the lower surface of the fork 24 descending by the spring force of the spring 23 interposed therebetween is fitted (engaged), it is always surely stationary at a rotation angle of 180 °. It is supposed to be.

  A traveling body 26 is in contact between the left and right side walls 14, 14 ′ of the cam wheel 7. The traveling body 26 is slid in the axial direction via a sliding member 29 on the inner surface of a small diameter portion 28 ′ of a supported cylindrical body 28 as shown in FIG. 2 at the tip of an arm piece 27 extending from the base 1. It is attached to the lower end of a shaft rod 30 that is pivotally supported. The shaft rod 30 is provided with a concave hole 30 ′ at the center of the upper surface, and a spring (coil spring) 32 is interposed between the concave hole 30 ′ and the lid body 31 with the upper surface of the cylindrical body 28 closed. The traveling body 26 is always pressed downward.

  The inner surfaces of the side walls 14, 14 ′ constitute guide walls 33 a, 33 b of the traveling body 26. The guide walls 33a, 33b are wide in the urging area A (see FIGS. 4 and 5) where the plunger rollers 16 ″ and 17 ″ of the plungers of the solenoids 16 and 17 come into contact with each other to slide the cam wheel 7 left and right. Although it is A ′, in the non-sliding area B (see FIGS. 4 and 5) where the cam wheel 7 is not slid, it is narrowed to become a narrow width B ′. The narrow width B ′ portion serves to return the traveling body 26 to the center of the cam wheel 7.

  The traveling body 26 is fitted in a groove 34 that is formed in an annular shape along the circumference of the cam wheel 7 (see FIGS. 5 and 6). The traveling body 26 fitted in the concave groove 34 travels while being fitted in a so-called neutral state in which none of the bevel gears 5, 5 ′ meshes with the bevel gear 4 rotating integrally with the rotor metal 3. Therefore, it does not shake (shake) in the axial direction. On the other hand, when the cam wheel 7 slides to the left and right together with the horizontal shaft 6 by the action of the tip rollers 16 ", 17" of the plungers 16 ', 17' selectively protruded by energization of the solenoids 16, 17, It is possible to escape against the spring pressure of the spring 32. For this reason, it does not prevent the cam wheel 7 from sliding left and right together with the horizontal shaft 6.

  The concave groove 34 engraved in the cam wheel 7 has a tapered surface in which the left and right groove walls 34a and 34b expand outward at a constant angle θ. This makes it easier to escape from the concave groove 34 in which the traveling body 26 travels when the cam wheel 7 slides due to the operation by energizing the solenoids 16 and 17. In order to facilitate the escape, the lower edge portion 26 ′ of the traveling body 26 is also a tapered surface having a small diameter toward the lower surface at a constant angle θ ′.

  Next, the operation of the present torsion race machine will be described. First, when a drive gear (large spur gear) 10 rotates in a horizontal direction from a main shaft (drive unit) (not shown), a spur gear 11 meshed with the main gear rotates horizontally around a rotation shaft 13, and the bevel gear 12 is rotated by the bevel gear 9. The horizontal shaft 6 is rotated via

  A cam ring 7 is fixed to the inner end of the horizontal shaft 6 through a slide connecting portion 8, and a solenoid 16 is connected to cam surfaces 15 a and 15 a ′ formed on the outer surfaces of the left and right side walls 14 and 14 ′ of the cam ring 7. , 17 plungers 16 ′, 17 ′ end rollers 16 ″, 17 ″ contact and slide, so that the rotation of the horizontal shaft 6 is transmitted to the bevel gear 4 of the rotor metal 3 through the bevel gears 5, 5 ′. As a result of driving the rotor metal 3 clockwise or counterclockwise, the spindle runner 18 is moved by the rotor metal, and the yarn 20 drawn from the bobbin 19 mounted on the spindle runner 18 is entangled with each other in a race forming portion (not shown). Knitting lace fabric.

  Between the left and right side walls 14, 14 ′ of the cam wheel 7, a concave groove 34 is formed in an annular shape along the circumference, and a traveling body 26 is fitted in the concave groove 34. Therefore, since the traveling body 26 is normally pressed downward by a spring (coil spring) 32, the bevel gears 5 and 5 ′ are connected to the bevel gear 4 that rotates integrally with the rotor metal 3. In the so-called neutral state where the gears are not engaged, the vehicle travels in the fitted state, so that it does not shake (shake) in the axial direction.

  On the other hand, as described above, the end rollers 16 ″ and 17 ″ of the plungers of the solenoids 16 and 17 selectively come into contact with the cam surfaces 15a and 15a ′ of the cam ring 7 so that the cam ring 7 is moved to the left and right together with the horizontal shaft 6. When the sliding force is applied, the traveling body 29 can escape against the spring pressure of the spring 32, so that the cam wheel 7 is not prevented from sliding to the left and right together with the horizontal shaft 6.

  The torsion race machine of the present application is capable of stably rotating a cam wheel that slides a horizontal shaft that rotates a rotor metal that moves a spindle runner (bobbin spindle) to the right or left. It has industrial applicability that can contribute to improvement.
