[Prior art]
2. Description of the Related Art Conventionally, a spinning nozzle cleaning device that cleans impurities adhering to the base surface of a spinning nozzle includes a swivel / spinning type. According to this method, two or more metal blades contact the spinning nozzle base surface and rotate while rotating to clean the base surface. However, if the discharge of the spinning yarn is stopped during cleaning, it is not possible to obtain a stable physical property of the spinning yarn immediately after cleaning. Therefore, it is preferable to perform the cleaning in a state where the yarn is discharged from the spinning nozzle base. However, if cleaning is performed without stopping spinning, there is a problem that effective cleaning cannot be performed because the yarn is entangled with the rotating blade.
[0003]
In order to solve this problem, a swiveling / vibrating cleaning device has been developed in which the blade does not rotate but swirls while vibrating (see Patent Document 1). In this cleaning device, the metal blade is swung along the swirling path by the swiveling means and vibrated by the vibrating means. According to this method, the blade is cleaned while spinning without tangling the thread. Can do. However, since the base surface to be cleaned has a slightly swollen center, there is a problem in that the blade edge of the vibrating blade collides with the base surface and is damaged.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
[0011]
FIG. 1 is a side view showing a spinning nozzle cleaning device of the present invention. The spinning nozzle cap 5 in the spinning machine includes a plurality of nozzle holes 51 for discharging spinning yarn. When the yarn is discharged from the nozzle holes 51, deposits adhere to the spinning nozzle base surface 50, which is the lower surface of the nozzle base 5. To do. In order to remove this deposit, the spinning nozzle cleaning device is positioned directly below the nozzle base 5 and cleans the base surface 50.
[0012]
The nozzle cleaning device includes: a cleaning unit 1 that removes deposits attached to the base surface 50; a lubricant application unit 3 that applies silicon oil to the base surface 50; and a yarn suction unit 2 that sucks the yarn being cleaned. I have. Since the yarn suction means 2 performs cleaning with the yarn discharged so that stable yarn physical properties can be obtained even after cleaning, the yarn suction means 2 sucks and removes unnecessary yarn during cleaning. The lubricant applying means 3 applies silicon oil to the base face 50 in order to prevent the cleaning means 1 from damaging the base face 50.
[0013]
The cleaning means 1 includes a single blade mechanism 10. The blade mechanism 10 has a blade 12 on the upper side. The blade tip at the tip of the blade 12 abuts on the base surface 50 and the blade mechanism 10 is swung and cleaned by the swivel mechanism 11. The yarn suction means 2 includes a yarn receiving member 20 for efficiently receiving the yarn discharged from the base surface 50. The yarn receiving member 20 is located directly below the base surface 50 and is open in a relatively wide area when facing the base surface 50. A first suction pipe member 21 is connected to the thread receiving member 20, and a suction path connecting member 22 made of a flexible hose is connected to the downstream side of the first suction pipe member 21. A second suction pipe member 23 and a suction source 25 having a blower 24 are connected to the connection member 22, thereby forming a yarn suction path.
[0014]
The first suction pipe member 21 is made of metal because it is located in the vicinity of the nozzle base 5 that becomes high in temperature, and the yarn receiving member is used to prevent an increase in the viscosity of the yarn without lowering the temperature of the base surface 50. A plurality of small holes are provided upstream of 20 and the first suction pipe member 21. Then, a swirl flow applying means 26 for applying a swirl flow to the first suction pipe member 21 is provided at a connection portion between the yarn receiving member 20 and the first suction pipe member 21. The swirl flow applying means 26 is configured to blow the compressed air in a direction eccentric to the axis of the first suction pipe member 21, and binds the yarn sucked into the first suction pipe member 21. Since the yarn can be entangled and sucked, the yarn can be prevented from adhering to the yarn suction path. Furthermore, a plurality of small holes are provided on the downstream side of the first suction pipe member 21 to keep the flow rate of the yarn in the yarn suction path uniform.
[0015]
2 to 5 are explanatory views of the cleaning means, and the cleaning means will be described below in detail based on the respective drawings. FIG. 2 is a perspective view showing the cleaning means. As described above, the blade 12 is turned by the turning mechanism 11 to clean the base face 50. The turning mechanism 11 has a rotating disk member 14 that supports a sleeve member 13, and a rotation speed detection gear 15 is connected to the rotating disk member 14. Further, a center shaft 16 is provided at the center of the rotation speed detection gear 15, and the rotation disk member 14 is rotated together with the rotation speed detection gear 15 by rotating the center shaft 16 by a turning drive source 17 formed of an electric motor. Then, the blade mechanism 10 turns.
[0016]
The rotation speed detection gear 15 has a plurality of teeth 15a around it at equal intervals, and detects the number of teeth 15a passing through a combination of a sensor and a detector (not shown), thereby rotating the disk member. 14 rotation angles are detected. Further, as will be described in detail later, by providing the blade mechanism 10 with the blade urging means 121, the contact pressure of the blade edge portion 120 with respect to the base surface 50 can be made uniform. By providing, damage to the base surface 50 can be prevented. A reciprocating drive source 18 (in this embodiment, an air cylinder) is provided below the blade mechanism 10.
[0017]
FIG. 3 is a front view for explaining the blade urging means. At the tip of the blade 12, there is a horizontally-shaped metal cutting edge 120. The cutting edge 120 abuts on the base surface 50, and in this state, the blade 12 is attached to the base surface 50 by turning. Remove the kimono. If the blade edge portion 120 can apply a uniform contact pressure along the inclination of the base surface 50, the blade edge portion 120 can be swung along the base surface 50 so that the blade biasing means can be efficiently cleaned. A displacement mechanism is provided. In this swing support mechanism, both end shafts 121a and 121a ′ of the blade edge portion 120 are pivotally supported by the blade edge holder member 121c, and the swing shaft 121b of the blade edge holder member 121c is pivotally supported by the main body member 122. ing.
[0018]
According to this blade urging means, first, as shown in FIG. 3A, the blade 12 is positioned directly below the base surface 50, and then the blade 12 is pushed up by the reciprocating drive source 18 as shown in FIG. 120 is pressed against the base surface 50. Then, by the operation of the swing support mechanism, the blade edge holder member 121c is rotated along the inclination of the base surface 50 about the swing shaft 121b, and the blade edge portion 120 further supports the both end shafts 121a and 121a ′. Therefore, the contact pressure with respect to the base surface 50 of the blade edge portion 120 becomes uniform.
[0019]
FIG. 4 is a side view for explaining the inclined support means. As shown in FIG. 4A, the blade 12 is supported on the upper portion of the blade support member 123, and the lower portion of the blade support member 123 is pivotally supported on the upper portion of the inclined link member 124 by the link shaft 123a. Further, the lower portion of the inclined link member 124 is pivotally supported on the upper portion of the push-up link member 19 by a link shaft 124a. The lower part of the push-up link member 19 is connected to the reciprocating drive source 18 through the sleeve member 13. The blade support member 123 communicates with a casing member 125 provided in the sleeve member 13 and is pivotally supported by a blade inclined shaft 125 a provided in the casing member 125. As a result of configuring such a link mechanism, the blade 12 is swung and at the same time the push-up link member 19 is pushed up by the reciprocating drive source 18 so that the nozzle of the spinning nozzle is formed according to the swiveling direction as will be described in detail later. The blade surface of the blade 12 can be inclined with respect to the surface 50.
[0020]
As shown in FIG. 4B, when the blade 12 is swung in the forward rotation direction α1 (rightward in the drawing), the blade 12 and the base surface are in contact with the base surface 50 because the tip of the blade 12 is in contact with the base surface 50. 50, the blade 12 tilts in the direction β1 (counterclockwise in the figure) opposite to the traveling direction about the blade tilting axis 125a, and the blade support member 123 is a stopper 125b provided in the casing member 125. The blade 12 can be pivoted while maintaining the inclination angle θ of the blade surface of the blade 12 with respect to the base surface 50 at an angle smaller than 90 degrees (about 88 degrees in this embodiment). Further, as shown in FIG. 4C, when the blade 12 is swung in the reverse rotation direction α2 (leftward in the figure), the blade 12 is moved in the reverse direction β2 (clockwise in the figure) from the traveling direction as described above. Tilt and swivel. If the blade 12 pivots in a state of being perpendicular to the base surface 50 (the state shown in FIG. 4A), the blade 12 vibrates (so-called chatter), so that the base surface 50 is damaged. By slightly tilting the blade 12 according to the turning direction (about 2 degrees in the present embodiment), the blade 12 can smoothly turn, suppress the occurrence of vibration, and prevent the base face 50 from being damaged.
[0021]
FIG. 5 is a plan view for explaining the trajectory of the blade. As described above, since there is one blade 12 according to the present invention, the length of the cutting edge portion 120 of the blade 12 corresponds to the radius φ of the base surface 50, and this cutting edge portion 120 is the center of the base surface 50. The base 50 is cleaned by swiveling around the base. Further, in order to prevent uneven cleaning, it rotates in the clockwise direction (forward rotation direction) α1 (see FIG. 5A), and then rotates in the antistatistical direction (reverse rotation direction) α2 (see FIG. 5B), and this is repeated. This forward / reverse rotation is configured to detect and control the rotational angle of the blade 12 by the rotational speed detection gear 15 so as to rotate 360 degrees or more (about 370 degrees in the present embodiment) in order to eliminate cleaning residue. Yes.
