Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a package removal device in an automatic winder.

When winding up the package in an automatic winder and taking it out, the package thread end is wound around the bobbin and cut. When winding the yarn end, it is preferable that the package yarn end is wound as close to the package cage as possible because there is no fear that the yarn end will come off the bobbin at the time of winding or at the end of winding.

Therefore, in the present invention, a rod is used to push the package cage in the direction of the bobbin axis to remove it from the cradle, and a rod is used to guide the thread of the traverse drum to the end of the bobbin when the package cage is separated from the traverse drum. The present invention is characterized in that it is used together with the thread guide having an inclined edge as a guide rod for winding the thread end to a position close to the package.

An embodiment of the device of the present invention will be described below with reference to the drawings.

have. A cam 32 is fixed to the drive shaft 31, and a cam follower 34 at the tip of a swing arm 33 is pressed against the cam 32 by the elastic force of a spring 35. The other end of the swinging arm 33 is connected via a rod 36 to one arm of a V-shaped lever 38 supported on a shaft 37, and the other arm of the V-shaped lever 38 is connected to a lever 40 via a rod 39. ing. The lever 40 is
It is fixed to a shaft 42 rotatably supported by a support member 41. A boss 43 is fixed to the shaft 42,
A boss 44 is fixed to the tip of the boss 43 so as to be perpendicular to the boss 43. At the center of the boss 44, a shaft 45 having a package extrusion/thread guide rod 9 fixed therethrough is rotatably supported. A pin 46 is fixed to the shaft 45, and a spring 4 is inserted between the stopper 47 fixed to the lever 40 and the tip of the pin 46.
8 is applied, and its elastic force urges the pin 46 to approach the end of the stopper 47. The package extrusion/thread guide rod 9 is roughly L-shaped as shown in FIG. 5, and its tip is bent in a wave-like manner as shown in FIG. .

Next, the operation of the device of the present invention will be explained. When the package 4 is full and it is to be taken out, the yarn end must first be wound onto the bobbin at a position in contact with the side surface of the package 4.

First, the fully wrapped package 4 must be separated from the traversing drum 6. To do this, a mechanism (not shown) is used to lower the lifting lever 50 (Fig. 4) located inside the moving vehicle 3, and the hook 5 at the tip
1 is engaged with a pin 53 protruding from the side of the cradle arm 52, and by raising the lifting lever 50, the cradle arm 52 is slightly rotated (counterclockwise in FIG. 1), and the traverse drum 6 and package cage 4 are Separate the distance between you and

Next, the thread Y extending between the traversing drum 6 and the fully wrapped package cage 4 is transferred to the side of the package cage and transferred to the moving vehicle 54.
You have to wrap it around. When the rod 17 is pulled up in the direction of arrow A in FIG. 3 by a cam (not shown), the lever 12 turns counterclockwise around the shaft 11, and when the shaft 16 at the tip of the lever 12 reaches the side surface at the center position of the package. The rod 17 stops being pulled up, and the lever 12 and support arm 15 move along the two-dot chain line 1.
The positions will be 2a and 15a. Subsequently, the rod 22 is pulled upward and the fan-shaped gear 21 turns clockwise. As the sector gear 21 rotates, the gear 14 meshing with the gear 21 rotates counterclockwise, and the shaft 11 to which the gear 14 is fixed also rotates in the same direction.
The triangular plate 13 fixed to rotates counterclockwise. That is, the rod 20a at the two-dot chain line position is pushed in the direction of arrow B, and the support arm 15 integrated with the lever 19
a turns in the direction of arrow C around the shaft 16a, and the thread guide 23 turns along the outer periphery of the package without contacting the package 4, passing the thread Y through the gap between the package 4 and the traversing drum 6. engage. Since the end edge 24 of the thread shifting guide 23 is inclined as shown in FIG. 25. This position is off the side of the package 4, and the yarn Y falls from the end of the package and is located between the package extrusion/yarn guide rod 9 and the side of the package. In this state, the thread Y is wound around the bobbin 54 to create a selvedge. The rotation of the package for wrapping the ears is performed by an auxiliary roller 27. That is, the auxiliary roller 27 pivotally supported by the swing arm 26 is rotationally driven in the direction of the arrow by a motor (not shown) via a belt, and rotates the package 4 in the direction of the arrow, that is, in the direction in which the yarn Y is wound up. At this time, the thread Y is wound around the bobbin 54 while being pressed against the side of the package 4 by the protrusions 9a and 9b of the package extrusion/thread guide rod 9.

Thereafter, the thread end is cut by a cutter (not shown), and the package 4 is removed from the cradle arm 52. The package 4 can be removed from the cradle arm 52 as follows.

5 and 6, when the cam follower 34 of the swinging arm 33 comes into contact with the recess of the cam 32 due to the rotation of the cam 3 fixed to the drive shaft 31 on the moving vehicle 3 side in the direction of the arrow, the spring 35 Swing arm 3
3 rotates counterclockwise. As a result, the lever 40 is rotated clockwise about the shaft 42 via the rod 36, the V-shaped lever 38, and the rod 39.
Therefore, the package extrusion/thread guide rod 9 is supported on the shaft 42 via the boss 44 and the shaft 45.
The L-shaped bent end pivots downward toward the package 4. Since the tip of the package extrusion/thread guide rod 9 is bent, when the rod 9 and the end surface 4a of the package 4 come into contact, the rod 9
Pushed in the direction of the arrow in the figure. This movement is shown in Figures 6 and 7.
The movement is against the elastic force of the spring 48 in the figure, and the rod 9 pivots about the shaft 42 in the clockwise direction in FIG. Therefore, in the ear wrap position where the rod 9 is in contact with the end surface 4a of the package, the pin 46 is pivoted away from the end surface 47a of the stopper 47.

When the ear wrap is completed in this state, a cradle arm release member (not shown) comes into contact with the lever 55 of the cradle arm 52 and opens the tip of the cradle arm 52 against the elastic force of the spring 56 provided on the cradle arm 52. The rod 9, which is urged in the direction opposite to the arrow in FIG. 2 by the resilient force, pushes the package 4 to the left in FIG. The package 4 that has come off the cradle arm 52 is transferred to the conveyor by the guide plate 7 shown in FIG. 1 and conveyed.

As explained in detail above, in the device of the present invention, since the package extrusion/yarn guide rod is provided which has a bent convex portion at the tip, the convex portion of the rod is pressed against the end face of the package when wrapping the end of the package yarn around the selvage. By doing so, the yarn end can be wound around the bobbin while being in contact with the end surface of the package cage, and an accident in which the yarn end is wound around a bobbin supporting spindle provided at the end of the cradle arm can be prevented. Can be done. Moreover, since the arm is in pressure contact with the end face of the bobbin by a spring, just by pushing open one arm of the cradle arm, the fully wound bobbin can be immediately removed from the cradle arm by the pressing force of the arm. There is no need to provide a member for taking out the winding bobbin, and the device can be simplified accordingly.

In addition, since the package cage has a thread guide with an edge that slopes toward the bobbin end on the side where the thread end is wound, when the thread guide guide is guiding the thread end, the guided thread The end always reaches the thread end winding side end of the package cage, where it engages with the bent convex part of the package cage extrusion/thread guide, ensuring that the thread end is wound in the specified position on the bobbin. .
