Description

  The present invention relates to a combing machine. More specifically, a trailing fleece fed from a pair of upper and lower detaching rollers is joined to a trailing fleece combed by rotation of a combing cylinder, and a rear end portion of the trailing fleece is connected to a top comb. It is related with the comber machine comprised so that it combed by.

  In the combing machine, the supplied wrap is gripped at the position where the nipper device is retracted, and a needle row (cylinder needle) in which the tip of the wrap is implanted in the combing cylinder is rolled up and the short fiber or the like (such as Nep) (Including impurities) to make a fleece. This action is called cylinder combing. The fleece is moved toward the detaching roller by the advance of the nipper device. Corresponding to the advance of the fleece, the detaching roller is reversed, the fleece previously pulled out (the preceding fleece) is moved backward, and the rear end of the fleece and the tip of the newly beaten fleece (following fleece) are connected. Overlapping. This action is called piecing. Thereafter, the detaching roller is rotated forward again, and the succeeding fleece joined to the preceding fleece is pulled out. At this time, the top comb rolls over the rear end of the fleece. This action is called top combing. The combing machine repeats cylinder combing, pecing and top combing. In a combing machine, both the combing action and the quality of pecing are major factors that determine the quality of the product.

  It is said that top combing is more important in both combing actions. When the top comb acts on the subsequent fleece, it is important that the top comb penetrates the fleece at an optimum depth in accordance with the nipper motion. Conventionally, when the distance between the detaching roller and the top comb at the forward end position of the nipper unit is adjusted to a preset value, the top comb pin rush depth and angle are set to appropriate values. A configuration in which the comb holder is positioned on the lower nipper so as to be adjustable and rotatable is disclosed (see Patent Document 1).

In addition, when the short fiber or the nep adheres and accumulates between the needles of the top comb or between the needles, the effective action of the top comb is impaired. In view of this, a method has been proposed in which the top comb needles or the short fibers and the nep attached and deposited between the needles are blown off with pressurized air (see, for example, Patent Document 2). In this method, the supply of pressurized air is controlled at precisely defined time points and precisely defined time intervals so that the pressurized air does not adversely affect the combing and piecing processes.
Japanese Patent Laid-Open No. 2-80623 Japanese Unexamined Patent Publication No. 7-48724

  However, in the configuration of Patent Document 1, the fleece is bent downward due to the frictional resistance between the top comb and the fleece, which adversely affects the fiber peening. Also, every time the distance between the detaching roller and the top comb at the forward end position of the nipper unit is changed, it is necessary to adjust the position of the top comb holder, which is troublesome. Further, as in Patent Document 2, in the method of blowing short fibers attached and deposited (grown) on the top comb by jetting of pressurized air, if the jetting time and jetting time of the pressurized air are not accurately controlled, the pressurized air Disturbs part of the fleece and deteriorates quality. In addition to the control system wiring, a pneumatic circuit is required, which complicates the configuration.

  The present invention has been made in view of the above-mentioned problems, and its first object is to suppress the fleece from being pushed downwardly when the top comb pierces the fleece, It is to make pecing smoother. A second object is to provide a combing machine that can achieve the first object and can suppress the adhesion and deposition (growth) of short fibers, neps and the like on the top comb.

In order to achieve the first and second objects, the invention according to claim 1 is characterized in that the lap is gripped in the middle of the backward movement of the swing motion of the nipper frame, and the lap is combed by the rotation of the combing cylinder. None, the grip of the lap is released during the forward movement of the swing motion, and the trailing fleece is joined to the leading fleece fed from the pair of upper and lower detaching rollers, and the rear end portion of the trailing fleece is combed with the top comb. A combing machine configured to oscillate the top comb and control means for controlling the excitation of the excitation means, the control means starting from the retreat start time of the nipper frame After the excitation of the means is interrupted, the top is again started when the fleece connected to the nipper portion is cut from the detaching roller. Controlling said driving means so as to oscillate the combs.

  In this invention, when the top comb pierces the fleece, if the top comb is vibrated by an excitation means (for example, ultrasonic vibration), the resistance when the top comb pierces the fleece becomes very small, and the top comb is necessary. Stings to a certain depth. In other words, even if the angle of the distance between the detaching roller and the top comb when the comb portion (needle, teeth, etc.) of the top comb pierces the fleece is not finely adjusted, the comb portion pierces the fleece without any trouble. The combing action by the top comb can be performed satisfactorily. Therefore, the top comb can efficiently beat the fleece fibers, and the quality of the fleece is improved. Further, when the top comb pierces the fleece, it is also suppressed that the fleece is pushed so as to bend downward.

Also, since the top comb is not vibrated from the start of the retraction of the nipper frame until the fleece is cut, the top comb is attached to the fleece that moves relative to the top comb while contacting the top comb, etc. Therefore, it is possible to prevent the short fibers and the like from being mixed with the product due to the fleece. Moreover, it can suppress that a short fiber, a nep, etc. adhere and deposit (grow) on a top comb from the time of cutting a fleece.

According to a second aspect of the present invention, in the first aspect of the invention, the top comb includes a plurality of comb members that roll the fleece and a support member that supports the comb member, and the excitation means includes: The vibrator is provided to vibrate the support member. Here, the “comb member” is the tip of the top comb, and when the fleece is pierced by the fleece, the fleece is wound up by the detaching roller, and the needle, needle, tooth, pin It means a member called "etc."

  When vibrating the top comb, if the vibrator of the excitation means vibrates the part where vibration is transmitted to the top comb, the top comb can be vibrated even if parts other than the top comb are vibrated. The farther the part is from the top comb, the greater the energy required to vibrate the top comb. In this invention, since the vibrator is provided so as to vibrate the support member constituting the top comb, the top comb can be vibrated with small energy.

The invention according to claim 3 is the invention according to claim 2 , wherein the vibrator is rigidly connected to a support member via a horn, and the side of the horn rigidly connected to the support member is a flat rectangular parallelepiped. The thickness of the portion of the base end side and the tip end side is constant, the base end side is thicker, and the thickness of the intermediate portion between the base end side constant thickness portion and the tip end side constant thickness portion Is formed in a shape that is notched with a curved surface that protrudes inward so that it gradually becomes thinner toward the tip side. In this invention, all the comb members can be vibrated uniformly compared with the case where a horn is formed in a cone shape.

According to a fourth aspect of the present invention, in the first aspect of the invention, the top comb includes a plurality of comb members that roll the fleece and a support member that supports the comb member, and the excitation means includes: The vibrator is connected to the plurality of comb members via a diaphragm extending in a direction orthogonal to the comb members. In the present invention, it is possible to efficiently vibrate a plurality of comb members with a single vibrator.

According to a fifth aspect of the present invention, in the first or second aspect of the present invention, the excitation means is provided so that the vibrator vibrates the top comb in a direction orthogonal to the moving direction of the fleece. It has been. According to the present invention, it is easier to attach the vibrator as compared with a configuration in which the vibrator is disposed on the front side of the support member and the tip of the vibrator is rigidly connected to the support member.

According to invention of Claims 1-5 , when a top comb stabs into a fleece, it can suppress that a fleece is pushed so that it may curve below, and can make pecing of a fiber more smooth. . Further, it is possible to suppress the short fibers and neps, etc. preparative Ppukomu adhesion, deposition (growth) to.

Hereinafter, an embodiment embodying the present invention will be described with reference to FIGS.
As shown in FIGS. 1A and 1B, two pairs of upper and lower detaching rollers 12 are disposed near the upper front side of the combing cylinder 11. A nipper frame 14 constituting a nipper device 13 is disposed behind the detaching roller 12 and above the combing cylinder 11. The nipper frame 14 is provided with a cushion plate 15 at the bottom, and a top comb 16 is fixed at the tip. The front side portion of the nipper frame 14 is suspended from the nipper pivot 19 via the support shaft 17 and the hinge link 18, and the rear end portion is suspended from the nipper shaft 22 via the support shaft 20 and the nipper lever 21. Yes. The nipper frame 14 is configured to swing back and forth so that the tip portion 15 a of the cushion plate 15 approaches and separates from the detaching roller 12 by reciprocating rotation of the nipper shaft 22.

  On the cushion plate 15, there is provided a feed roller 23 that rotates intermittently and feeds a lap L required for one combing. A support shaft 24 is provided at the center portion of the nipper frame 14, and a nipper arm 26 having a nipper knife 25 fixed to the tip thereof is rotatably supported at the center portion of the support shaft 24. A spring rod 28 is connected to the rear end portion of the nipper arm 26 via a support shaft 27. The spring end 28 a of the spring rod 28 is supported by a bracket 30 that is rotatable with respect to the machine frame 29 and fixed by bolts 31.

  The nipper knife 25 is opened and closed at a predetermined timing by the forward / backward swinging motion of the nipper frame 14 and cooperates with the cushion plate 15 to sandwich the lap L. The cushion plate 15 and the nipper knife 25 constitute a nipper portion. The spring rod 28 is used to adjust the opening / closing timing of the nipper knife 25 when the nipper gauge is changed.

  The top comb 16 is inserted into a groove formed in the front side portion of the nipper frame 14 so as to be movable in the vertical direction, and is held at a predetermined position by a holding member (not shown). The top comb 16 is composed of a plurality of needles 32 serving as comb members that roll over the fleece F and a support member 33 that supports the needles 32. The needle 32 is formed by fixing a tip portion 32a formed separately. The top comb 16 can be moved and adjusted with respect to the nipper frame 14 in a known configuration (not shown), and the penetration depth of the needle 32 into the fleece F during top combing can be adjusted.

  The nipper frame 14 is provided with excitation means 34 for vibrating the top comb 16. The vibrator 35 constituting the excitation means 34 is supported by a bracket 36 fixed to the nipper frame 14. The support member 33 is rigidly connected to a horn 37 that is excited by the vibrator 35. The horn 37 is formed in a substantially conical shape, and is rigidly connected to the lower part of the front surface of the support member 33 by brazing at the tip, and is fixed to the vibrator 35 on the surface opposite to the surface rigidly connected to the support member 33. ing. The front end surface of the horn 37 is formed on a plane orthogonal to the axial direction of the vibrator 35, and the horn 37 is provided perpendicular to the support member 33.

  A so-called Langevin-type vibrator is used as the vibrator 35 and includes a pair of ring-shaped piezoelectric elements 38a and 38b as shown in FIG. A ring-shaped electrode plate 39 is disposed between the piezo elements 38a and 38b, and metal blocks 40 and 41 that are in contact with the surface of the piezo elements 38a and 38b opposite to the side in contact with the electrode plate 39 are secured by bolts (not shown). The vibrator 35 is configured by tightening and fixing. The bolt is screwed into a screw hole (not shown) formed in the metal block 40 from the metal block 41 side. Both metal blocks 40 and 41 are in a state of being electrically connected to each other via bolts. A flange 40a is formed at the tip of the metal block 40, and the metal block 40 is fixed to the bracket 36 at the flange 40a.

  As shown in FIG. 3, the electrode plate 39 is connected to an oscillator 42 fixed at an appropriate position on the machine base via a wiring 43a, and the ground terminal of the oscillator 42 is connected to the metal block 41 via a wiring 43b. . That is, the vibrator 35 is electrically connected to the oscillator 42. The vibrator 35, the horn 37, and the oscillator 42 constitute excitation means 34 that vibrates the top comb 16. The oscillator 42 excites the vibrator 35 so as to vibrate the top comb 16 at a frequency higher than the human audible range.

  The oscillator 42 is controlled by the control device 44. The control device 44 constitutes control means for controlling the excitation of the excitation means 34. The controller 44 does not output the excitation command signal to the oscillator 42 during the entire combing cycle, but intermittently outputs the excitation command signal to the oscillator 42. Specifically, an excitation command signal is output from the time when the tip of the top comb 16, that is, the needle 32 pierces the fleece F to the time when the piercing ends, and the output is interrupted from the time when the nipper frame 14 starts to retract, and then the detaching The output is resumed from the point when the fleece F connected to the nipper portion is cut from the roller 12. The control device 44 sets the output timing of the excitation command signal based on a value (referred to as an index) obtained by equally dividing the rotation angle position of the combing cylinder 11 (in this embodiment, 40 equally).

  Next, the operation of the apparatus configured as described above will be described with reference to FIG. FIGS. 2A to 2H are schematic side views showing the relationship among the combing cylinder 11, the detaching roller 12, the cushion plate 15, the top comb 16, and the nipper knife 25 together with indexes in the combing cycle. In addition, the number drawn on the upper side of the frame of each figure shows the index of the state of the figure.

  When the combing machine is operated, the nipper frame 14 performs forward / backward swinging motion as the nipper shaft 22 reciprocates. The nipper knife 25 opens and closes at a predetermined timing by the forward / backward swing motion of the nipper frame 14, and grips the lap L supplied by the feed roller 23 in cooperation with the tip 15 a of the cushion plate 15.

  When the nipper knife 25 is closed during the retraction of the nipper frame 14, the front end of the cylinder needle row 11a faces the lap L. Then, when the nipper frame 14 continues to retreat from that state, the cylinder needle row 11a is in a state of hitting the lap L as shown in FIG. 2C, and cylinder combing is started. In the state of the index 40 (= 0) when the nipper frame 14 has reached the last retracted position, as shown in FIG. 2 (d), the cylinder needle row 11a is still engaged with the lap L, and the cylinder combing is continued. ing. From this state, the nipper frame 14 resumes moving forward, and at the index 2 shown in FIG. 2 (e), the engagement between the cylinder needle row 11a and the lap L is completed, and the combing by the combing cylinder is completed.

  Thereafter, the reverse rotation of the detaching roller 12 is started, the preceding fleece F1 is retracted, and the state shown in FIG. Thereafter, the nipper knife 25 is opened while the nipper frame 14 continues to advance, the feed roller 23 is rotated by a predetermined amount, and the lap L is fed by a predetermined amount, resulting in the state of FIG. Next, the forward rotation of the detaching roller 12 is started, the take-up of the preceding fleece F1 is started, and the subsequent fleece F2 is joined to the preceding fleece F1 to be in the state shown in FIG. At this time, the needle 32 pierces the fleece F. Further, when the nipper frame 14 continues to advance and the nipper frame 14 reaches the forward end as shown in FIG. 2A, the forward rotation of the detaching roller 12 is stopped.

  Thereafter, the nipper frame 14 is retracted in a state where the rotation of the detaching roller 12 is stopped, and the state shown in FIG. From this state, the nipper frame 14 continues to retreat, and the fleece connected to the nipper portion from the detaching roller 12 is cut off during retreat. And it will be in the state of Drawing 2 (c) corresponding to lap L where the front end of cylinder needle row 11a hangs down from a nipper part again.

  The needle 32 starts to pierce the fleece F during the transition from the state of FIG. 2 (g) to the state of FIG. 2 (h), and when the nipper frame 14 reaches the forward end, the needle 32 changes to the fleece F. On the other hand, it will be in the most deeply stabbed state. Since the control device 44 outputs an excitation command signal to the oscillator 42 from the time point of FIG. 2G to the time point of FIG. 2A, the oscillator 42 excites the vibrator 35, and the top is driven by the vibrator 35. The comb 16 is vibrated. The vibrator 35 is excited at a predetermined frequency (for example, around 20 kHz).

  In a state where the top comb 16 is not vibrated, unless the angle at which the needle 32 pierces the fleece F is adjusted to an appropriate value, the needle 32 does not pierce to an appropriate depth due to frictional resistance between the needle 32 and the fleece F. The fleece F is curved in a convex state downward. As a result, effective combing by the top comb 16 when the nipper frame 14 is retracted is not performed. However, in this embodiment, since the top comb 16 is vibrated until the time when the needle 32 completes piercing the fleece F, the frictional resistance between the needle 32 and the fleece F is reduced. As a result, even if the angle at which the needle 32 is pierced into the fleece F is not an appropriate angle, the needle 32 smoothly pierces to an appropriate depth without causing the fleece F to curve downward, and the top comb 16 is effective combing.

  Further, the control device 44 interrupts the output of the excitation command signal to the oscillator 42 until the fleece F between the detaching roller 12 and the nipper part is cut off from the time when the nipper frame 14 starts to move backward, and when the fleece F is cut off. The output of the excitation command signal to the oscillator 42 is resumed. The period from the start of retraction of the nipper frame 14 to the time when the fleece F is cut is a period in which top combing is performed by the top comb 16, and if the frictional resistance of the needle 32 is too low at this time, short fibers, neps, etc. In some cases, the fleece F is not removed from the fleece F even if it comes into contact with the fleece F and is taken off together with the fleece F when the detaching roller 12 rotates forward. However, since the top comb 16 is not vibrated during this period, occurrence of such a problem is avoided.

  Further, after the fleece F between the detaching roller 12 and the nipper portion is cut, the control device 44 resumes outputting the excitation command signal to the oscillator 42. If the short fiber or the nep attached to the top comb 16 is left in the top combing, it gradually grows during the top combing, and the top comb 16 is in a state of being troubled when the top comb 16 pierces the fleece F. After the fleece F is cut, even if the top comb 16 is vibrated, the top combing is not adversely affected. Then, by vibrating the top comb 16, the short fibers and the nep attached to the top comb 16 are removed from the top comb 16 and removed. The control device 44 maintains the output of the excitation command signal to the oscillator 42 until the nipper frame 14 starts to retract.

According to this embodiment, the following effects can be obtained.
(1) The combing machine includes an excitation unit 34 that vibrates the top comb 16 and a control device 44 that controls the excitation of the excitation unit 34. Therefore, when the top comb 16 is pierced into the fleece F, if the top comb 16 is vibrated by the excitation means 34 (for example, ultrasonic vibration), the resistance when the top comb 16 pierces the fleece F becomes very small, The top comb 16 can be inserted to the required depth without any problem. For this reason, when the top comb 16 pierces the fleece F, the fleece F is prevented from being pushed downward so that the fibers are peated smoothly. In addition, even if the angle of the top comb is not finely adjusted every time the distance between the detaching roller and the top comb when the comb part (needle, teeth, etc.) of the top comb sticks into the fleece, The combing action by the top comb can be performed satisfactorily. Therefore, the top comb 16 can efficiently beat the fiber of the fleece F, and the quality of the fleece F is improved.

  (2) The control device 44 controls the excitation means 34 so as to vibrate the top comb 16 from the time when the tip (needle 32) of the top comb 16 is pierced into the fleece F to the end of piercing. Therefore, the resistance when the top comb 16 is stuck in the fleece F becomes very small, and the top comb 16 is stuck to a necessary depth.

  (3) The control device 44 vibrates the top comb 16 again from the time when the fleece F connected to the nipper portion is disconnected from the detaching roller 12 after the excitation of the excitation means 34 is interrupted from the time when the nipper frame 14 starts to move backward. The excitation means 34 is controlled so that Accordingly, since the top comb 16 is not vibrated during the top combing, the friction between the short comb and the nep attached to the fleece F that moves relative to the top comb 16 and the top comb 16 is caused. The resistance does not become too small, and it is possible to suppress short fibers and the like from being mixed with the product due to the fleece. In addition, since the top comb 16 is vibrated after the top combing is finished, the short fibers and the nep attached to the top comb 16 during the top combing are removed, and the short fibers and the nep are attached to the top comb 16. Accumulation (growth) can be suppressed. Further, unlike the configuration in which short fibers and the like are blown away with pressurized air as in Patent Document 2, the blown airflow does not disturb the fibers of the combing cylinder part and the quality of the fleece F is not deteriorated.

  (4) The top comb 16 includes a plurality of needles 32 that hold the fleece F and a support member 33 that supports the needles 32, and the excitation means 34 is provided so that the vibrator 35 vibrates the support member 33. It has been. Therefore, it is possible to vibrate the top comb 16 with a small amount of energy as compared with a configuration in which a portion other than the top comb 16, for example, the nipper frame 14 is vibrated by the vibrator 35.

  (5) The control device 44 sets the output timing of the excitation command signal based on a value (called an index) obtained by equally dividing the rotation angle position of the combing cylinder 11 (in this embodiment, 40 equally). Therefore, the frictional resistance of the top comb 16 can be easily reduced only when necessary.

The embodiment is not limited to the above, and may be embodied as follows, for example.
The horn 37 is not limited to a substantially conical shape. For example, as shown in FIG. 4, the side that is rigidly connected to the support member 33 is formed in a flat and substantially rectangular parallelepiped shape, and the width direction is the axis of the detaching roller 12. The support member 33 may be rigidly connected so as to be parallel to the direction. More specifically, the horn 37 has a side that is rigidly connected to the support member 33, a part of a flat rectangular parallelepiped, the thickness of the base end side and the tip end side are constant, the base end side is thicker, and the base It is formed in a shape that is cut out by a curved surface that protrudes inward so that the thickness of the intermediate portion between the constant-thickness portion on the end side and the constant-thickness portion on the front end side becomes gradually thinner toward the front end side. That is, the horn 37 is formed in a shape in which a quadratic curve is opposed from the middle toward the tip side in the longitudinal section. In this case, all the needles 32 can be vibrated uniformly compared with the case where the horn 37 is substantially conical.

  ○ Instead of the configuration in which the vibrator 35 vibrates the support member 33, as shown in FIG. 5, a vibration plate 45 extending in a direction orthogonal to the needle 32 is fixed to the tip of the horn 37, and a plurality of needles are fixed to the vibration plate 45. 32 may be connected. That is, the vibrator 35 is connected to a plurality of comb members (needle 32) via the diaphragm 45. With this configuration, it is easy to efficiently vibrate a plurality of comb members with a single vibrator.

The bracket 36 that supports the vibrator 35 may be made of an I-shaped material or a groove-shaped material in order to increase rigidity, instead of a flat plate.
○ Instead of providing the oscillators 42 on each combing head, the oscillators 35 of all the combing heads may be excited by one oscillator 42 as in the case of the controller 44, or a plurality of (for example, two or three). The combing head may share one oscillator 42.

  The excitation means 34 may oscillate the top comb 16 at least from the time when the tip of the top comb 16 pierces the fleece F until the end of piercing. Depending on the operating conditions of the combing machine, for example, the fiber material of the wrap, It is not always necessary to interrupt the vibration.

  The control device 44 controls to lower the vibration frequency or vibrate at a frequency deviated from the resonance frequency instead of controlling the excitation means 34 to interrupt the vibration of the top comb 16 by the excitation means 34. May be. In this case, the top comb 16 has a higher frictional resistance of the top comb when the vibration frequency is changed than when the tip end portion of the top comb 16 is stuck in the fleece F until the end point. As a result, the top comb 16 can easily remove the short fibers and the like from the fleece F.

  The direction in which the top comb 16 is vibrated is not limited to the direction along the moving direction of the fleece but may be a direction orthogonal to the moving direction of the fleece. For example, as shown in FIG. 6, the vibrator 35 may be fixed to the nipper frame 14 via the bracket 36 so that the tip of the horn 37 is rigidly connected to the side surface of the support member 33. In this case, as compared with the configuration in which the vibrator 35 is disposed on the front side of the support member 33 and the tip of the horn 37 is rigidly connected to the support member 33, the attachment work of the vibrator 35 is facilitated.

The forward start time and reverse start time of the nipper frame 14 or the opening / closing timing of the nipper knife 25 are not limited to the index.
The transducer 35 is not limited to a Langevin type transducer as long as a desired frequency and amplitude can be obtained. Further, instead of the vibrator 35 formed using a piezoelectric material, the vibrator may be formed using a magnetostrictive element or a giant magnetostrictive element (piezoelectric ceramic or the like).

O You may fix directly to the part which vibrates the vibrator | oscillator 35, without providing the horn 37. FIG.
The comb member is not limited to the needle 32 or the needle that is formed in a linear shape, but may be a plate (blade shape) that is called a tooth. Further, the needle 32 is not limited to the configuration in which the distal end portion 32a formed separately is rigidly connected, and may be configured with the same wire material from the proximal end to the distal end portion.

The rigid body connecting means between the horn 37 and the support member 33 or the diaphragm 45 is not limited to brazing, and appropriate means such as screw fastening can be used.
The top comb 16 is not limited to a configuration in which the top comb 16 is fixed to the nipper frame 14 and moves back and forth together with the nipper frame 14. For example, the top comb 16 is attached to the nipper frame 14, the back and forth motion is performed together with the nipper frame 14, and the vertical motion is actively performed separately from the nipper frame 14, or the top comb is driven independently of the nipper frame 14. It may be a method to be used.

The following technical idea (invention) can be understood from the embodiment.
