Description

  The present invention copes with various causes that cause rotation failure of the rotor metal that moves the spindle runner, and can reduce damage to various parts that transmit rotation to the rotor metal and prevent pattern collapse. It relates to torsion racing machines.

  Generally, in a torsion race machine, as disclosed in JP-A-8-284051, rotor metals are arranged on the same circle, spindle runners are interposed between arc recesses of the rotor metal, and each rotor metal is adjacent to the right and left rotors. The spindle runner is alternately moved by one step by rotating 180 ° in the arc concavity facing the metal.

  When the spindle runner is moved continuously for several steps, as shown in FIG. 5, one spindle runner S at the position a is rotated by the broken arrow A ′ by rotating the rotor metal A 180 ° to the right as shown by the arrow. It moves one step along the trajectory (inward) and reaches the 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 ′ moves one step from the position b through the locus (outward) of the broken line arrow B ′, and the position c become. Subsequently, when the rotor metal C is rotated 180 ° to the right as indicated by the arrow, the rotor metal C moves one step from the position c through the locus (inward) of the broken line arrow C ′, and is sequentially repeated so as to reach the position d.

In the above torsion racing machine, one rotor metal is rotated 180 ° while the rotor metal adjacent to the left and right faces the circular arc recesses and stopped, and the spindle runner is repeatedly operated repeatedly. However, it is important that one rotor metal and the stop angle of the rotor metal adjacent to the rotor metal are always linked in a timely manner. This is important for torsion racing machines that can be selected. This timing error causes a rotation failure due to a rotor metal collision. Also, the rotation failure caused by the thread pulled out from the many bobbins mounted on the spindle runner and gathered in the race forming section, and part of the operator's work clothes that fix this breaks into the spindle etc. Or, there was also a rotation failure caused by a broken thread entangled with the bobbin spindle like a spider web.
JP-A-8-284051

    However, the rotation of the rotor metal is forcibly stopped due to the rotation failure caused by the collision of the rotor metal, the rotation failure that occurs during the repair of the broken yarn, or the rotation failure that occurs when the broken yarn gets entangled with the bobbin spindle. In such a case, a large obstacle (damage) is given to various parts that transmit rotation to the rotor metal. Therefore, although it has been necessary to reduce the damage as much as possible, there is no effective mitigation measure at present.

  In view of the above-described points, the present invention provides a rotation failure caused by a collision between adjacent rotor metals due to an improper timing, a rotation failure caused by a part of an operator's work clothes being caught in a spindle or the like, The purpose is to provide a torsion race machine that can immediately take measures against rotation obstacles caused by entanglement, reduce damage to various parts that transmit rotation to the rotor metal, and take preventive measures such as pattern collapse. It is said.

  In order to achieve the above object, a torsion race machine according to the present invention has a horizontal axis for driving a rotor metal that is fitted in a vertical direction so as to be able to rotate in a horizontal direction on a vertical axis arranged at a predetermined interval on a base. A transmission gear for transmitting the power from the prime mover is provided, and a split surface between the horizontal axis connecting side and the prime mover linked side is provided in the shaft core portion of the transmission gear, and the load from the horizontal axis side is provided on the split surface. Is that the prime mover linkage side is moved up against the spring pressure, a load cam from the prime mover linkage side is formed with an integrated cam, and a sensor for monitoring the prime mover linkage side upward movement is provided. As a feature, transmission is normally continued for addition on the prime mover side, and for trouble on the rotor metal side, transmission is stopped by the cam action of the shaft core part of the transmission gear and rotation is transmitted to the rotor metal. Configured so as not to damage the parts .

  The torsion race machine according to the invention described in claim 2 is characterized in that the cam is formed with a slope and a step portion, and the slopes slide on the load from the rotor metal side. Thus, the cam action is stopped, and the load from the driving part side can be maintained in the transmission state as it is.

  Furthermore, in the torsion race machine according to the invention described in claim 3, the sensor outputs a stop signal to the prime mover, and rotation that occurs during rotor metal collision or broken thread repair The machine can be stopped immediately when a failure occurs.

  Furthermore, in the torsion race machine according to the invention described in claim 4, the spring includes a thrust bearing fitted on the shaft core portion of the transmission gear and an extension shaft raised from the top surface of the shaft core portion. It is characterized in that it is interposed between the upper end and the cam so that the cam action of the cam formed on the split surface of the shaft core can always be maintained.

  According to the present invention, normal rotation can be transmitted to the rotor metal in response to the addition from the prime mover side. On the other hand, in the case of trouble on the rotor metal side, the cam formed on the shaft core part of the transmission gear is detached and transmitted. Stopped so that the parts that transmit the rotation of the rotor metal were not damaged significantly. Therefore, a failure caused by a collision between one rotor metal and the adjacent rotor metal on the left or right side, a rotation failure caused by a part of the operator's work clothes being caught in the spindle, or a broken thread entangled with the spindle. Even if there is a rotation failure that occurs, the large force transmitted to the horizontal axis for driving the rotor metal can be instantaneously reduced, and the cam of the shaft center part of the transmission gear is released and the cam action is stopped This makes it possible to monitor various events and the like.

  Further, according to the invention described in claim 2, since the load from the rotor metal side slides on the slope, and the load from the prime mover side keeps the transmission state continuously, The present invention has an excellent effect that it can quickly and smoothly cope with a spindle rotation failure that occurs when an operator's work clothes are entangled with the spindle or a broken thread is entangled with the spindle.

  Furthermore, according to the invention described in claim 3, when a rotation failure or the like that occurs during rotor metal collision or broken thread repair occurs, the machine can be stopped immediately and there is a risk of causing pattern collapse or the like. There is an excellent effect of not.

  Furthermore, according to the invention described in claim 4, since the force is applied in the direction in which the cams formed on the split surface of the transmission gear shaft mesh with each other, the response to the trouble on the rotor metal side is extremely fast. There is an effect.

  Next, an embodiment of the present invention will be described. FIG. 1 is a side sectional view showing a drive part of a rotor metal, FIG. 2 is an enlarged sectional view showing a mechanism for transmitting the power of a driving part to a horizontal axis for driving the rotor metal, FIG. 3 is an explanatory view of a cam, and FIG. FIG. 5 is an explanatory view showing the action of the rotor metal and the moving state of the spindle runner.

  A rotor metal 3 is fitted to a vertical shaft 2 that is annularly arranged at a predetermined interval along the outer peripheral portion 1 ′ of the base 1 of the torsion race machine T so as to be rotatable in the horizontal direction, and is fixed by a pin 2 ′. ing. A bevel gear 12 is fixed to the vertical shaft 2, meshed with the bevel gears 13 and 14 of the horizontal shaft 4, and can receive forward and reverse rotation from the horizontal shaft 4. The horizontal shaft 4 is connected to a spur gear 6a that constitutes a transmission gear 6 that meshes with a driving gear (large spur gear) 5 that is driven from a driving portion (not shown). The driving gear 5 bears only a plurality of (for example, eight) horizontal shafts 4 and is dispersed by a plurality of driving gears as a whole.

  The transmission gear 6 includes a spur gear 6 a meshed with the driving gear 5, a bevel gear 6 b provided rotatably on the lower surface thereof, and a common shaft portion 6 c. The shaft core portion 6c is pivotally supported by bearing means 1b fixed to the base 1 by fixing means 1a. The bevel gear 6b is attached to the shaft core portion 6c via a bearing 6b 'and meshes with a bevel gear 7 provided at the end of the horizontal shaft 4. In other words, the spur gear 6a linked to the driving gear 5 is transmitted to the horizontal shaft 4 via the bevel gears 6b and 7 and drives the rotor metal 3 together with the vertical shaft 2 via the bevel gears 14 and 12. Yes.

  The shaft core portion 6c, which is a common shaft of the spur gear 6a and the bevel gear 6b constituting the transmission gear 6, is horizontally below the driving portion connecting side (spur gear 6a) and above the horizontal shaft connecting side (bevel gear 6b). It is divided in the direction to constitute a dividing surface 8 (see FIG. 2). As shown in FIG. 3, the dividing surface 8 is engaged with a convex portion having a srobe 9a and a step portion 9b on the upper side and a concave portion having a srobe 9a 'and a step portion 9b' on the lower side. Two srobes 9a and 9a 'and stepped portions 9b and 9b' are provided opposite to each other around the dividing surface 8 of the shaft core portion 6c. Of course, it is not limited to two.

  As a result, troubles (for example, collision of the rotor metal, entanglement of the operator's work clothes with the spindle, or entanglement of the broken thread with the spindle) caused the rotor metal to stop rotating. As a result, a load is applied to the bevel gear 6b. In such a case, since the upper srobe 9a slides on the lower srobe 9a 'and stops the cam action, the spur gear 6a connected to the driving unit connecting side is a spring (coil spring) 10 described later. It moves up against the spring pressure. On the other hand, the upper step portion 9b and the lower step portion 9b 'are integrated with the load from the driving unit connecting side and the transmission is continued as it is.

  The spring (coil spring) 10 includes a thrust bearing 10a fitted in a concave groove 6a 'formed along the shaft core portion 6c on the upper surface of the spur gear 6a constituting the transmission gear 6, and the shaft core portion. It is interposed in a compressed state between the upper end flange 10c of the extension shaft 10b raised from the top surface of 6c. Therefore, the thrust bearing 10a presses the spur gear 6a downward from its upper surface so that the srobes 9a, 9a ′ of the cam 9 and the step portions 9b, 9b ′ are engaged with each other. In FIG. 2, the upper end flange 10c uses the upper end flange of a cylindrical body 10d screwed to the extension shaft 10b. The cylindrical body 10d is effective in that the inner periphery of the spring 10 is in close contact and does not run out.

  The horizontal shaft 4 side generates a load due to trouble, the upper slobe 9a slides on the lower slobe 9a ', and the spur gear 6a connected to the driving side is raised against the spring pressure of the spring 10. Although it moves, the sensor 11 is installed in order to monitor the change by the upward movement. The sensor 11 is attached to a support member 11 ′ installed on the base 1 and faces the spur gear 6 a. That is, as shown in FIG. 4, the sensor 11 is operated by the closeness of the spur gear 6a by an upward movement amount h generated when the srobes 9a and 9a 'are climbed. Thus, the sensor 11 senses that a stop signal is output to a prime mover (not shown) to immediately stop the machine so as not to cause pattern collapse or the like.

  Next, the operation of the present torsion race machine will be described. First, when the driving gear 5 connected from the driving portion rotates, the spur gear 6a constituting the transmission gear 6 meshed with the driving gear 5 rotates on the shaft core portion 6c, and is formed on the split surface 8 of the shaft core portion 6c. The cam 9 rotates integrally with the stepped portions 9b and 9b 'engaged with each other, and the bevel gear 6b rotates the horizontal shaft 4 via the bevel gear 7, so that the rotor metal 3 is rotated normally. The rotation of the rotor metal moves the spindle runner 15, the bobbin 16 mounted on the spindle runner 15 moves, and the yarn 17 drawn from the bobbin 16 is entangled in a lace forming portion (not shown) to form a knitted lace fabric. To do.

  Next, during race knitting, the rotation timing of the rotor metal that moves the spindle runner is incorrect, which causes a rotation failure of the rotor metal caused by a collision with the adjacent rotor metal, and part of the operator's work clothes get caught in the spindle etc. If the spindle rotation failure occurs due to the rotation of the spindle, or the spindle rotation failure occurs when the broken thread is entangled with the bobbin spindle like a spider web, the cam formed on the dividing surface 8 of the shaft core portion 6c. The upper slobe 9a of the motor 9 slides on the lower slobe 9a ', moves the spur gear 6a connected to the driving side against the spring (coil spring) 10 and senses the upward movement. 11 outputs a stop signal to the prime mover, stops the torsion race machine, damages the rotor metal, and transmits the rotation to the rotor metal. Mitigation of damage to the various components are, such as pattern collapse of the race can be prevented in advance.

  The torsion race machine of this application stops the torsion race machine, prevents damage to the rotor metal when there is an obstacle in the rotation of the rotor metal that moves the spindle runner, and reduces damage to various parts that transmit rotation to the rotor metal. , Preventing pattern collapse and increasing industrial applicability.
