Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is to raise a bobbin suspended from a predetermined position on a bobbin hanger to fit on the bottom of the bobbin and push the bobbin up to lift the bobbin from the bobbin hanger. The present invention relates to a bobbin position restricting device when a bobbin removing device for removing is used.

(Prior Art) In recent years, labor saving has progressed in spinning factories, and there is an increasing number of cases in which automation in each process is taken one step further from automation in each process and automation of connection between each process and conveyance. Several proposals have also been made for connection between the roving and spinning processes and automatic transfer of bobbins. JP-B-55-36731 and JP-A-6-36731.
In the 1-194228 publication, etc., a main conveying path connecting the roving process and the spinning process is provided on the ceiling, and a conveying route branched from the main conveying route along the roving frame and the spinning frame is provided. A method is disclosed in which the wound roving spool is conveyed to a spinning machine via a main conveying path and an empty bobbin used in the spinning machine is conveyed to the roving machine.

When the bobbin is automatically transported by using the transport path laid on the ceiling in this way, generally, a bobbin hanger is equipped on the transporter traveling on the transport path, and the bobbin hanger is equipped with a roving bobbin (full bobbin) or an empty bobbin. The bobbin is carried while the is suspended. As shown in FIG. 9, the bobbin hanger 41 has an operating member having a pair of hooks 42.
A known bobbin hanger is used in which the hook claws 42 are moved and inserted between the protruding position and the retracted position by the vertical movement of 43.
As shown in the figure, the bobbin B is removed from the bobbin hanger 41 by the vertical movement of a bobbin removing device 45 having a peg 44 capable of fitting with the bottom of the bobbin B.

In the conventional device, when the bobbin hanger 41 freely shakes during the transportation of the preliminary roving bobbin, there is a risk that the preliminary roving windings may collide with each other due to vibration during transportation to damage the roving or cause the roving to sag. 41 is fixed to the carrier 46 so as not to swing. Therefore, when the carrier 46 is carried into the upper position corresponding to the bobbin removing device 45, the bobbin B may be inclined due to the tilt of the carrier 46, the tilt of the bobbin hanger 41 itself, or the protruding position of the latch claw 42 due to a manufacturing error. May be placed in a slightly tilted state without being hung vertically. Since the length of the bobbin B is long even if the inclination of the bobbin hanger 41 is slight, the peg of the bobbin removing device 45 is provided at the bottom of the bobbin as shown in FIG.
There is a problem in that the bobbin removing device 45 moves up and down, which hinders the removal of the bobbin due to the vertical movement of the bobbin removing device 45.

Configuration of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, in the present invention, a support body that can be fitted to the bottom of the bobbin is provided, and the support is disposed below the bobbin that is suspended from the bobbin hanger. In a state where the bobbin is lifted up and down, and the support is fitted to the bottom of the bobbin, the bobbin is pushed up and removed from the bobbin hanger. The bobbin outer periphery is movably arranged in a retracted position where it cannot be engaged with the bobbin, and is moved to an operating position prior to the upward movement to a fitting position with the bobbin bottom of the bobbin removing device. And a regulating member for regulating the position of the bobbin so that the bottom of the bobbin corresponds to the support.

(Operation) In the device of the present invention, the restricting member is moved from the retracted position to the operating position before the bobbin removing device moves upward to a position where it can engage with the bottom of the bobbin suspended from the bobbin hanger. Then, the restricting member engages with the outer periphery of the bobbin to restrict the position of the bobbin so that the bottom part thereof corresponds to the support of the bobbin removing device, and in this state, the bobbin removing device is fitted with the bobbin bottom part. The bobbin is removed from the bobbin hanger by being moved up to the position, the support is securely fitted to the bottom of the bobbin, and the bobbin is removed.

Next, the operation of the device configured as described above will be described.
By the way, the bobbin position regulating device 11 includes the guide arms 16a to 16a.
While c, 17a to 17c are held at the retracted position shown by the chain line in FIG. 1, the c and 17a to 17c are moved along the roving machine stand 2 and stopped at a predetermined position to perform pipe replacement work. When the empty bobbin B is removed from the bobbin hanger 4 of the bobbin carrier 5 which stands by on the carrying rail 3 by the vertical movement of the empty bobbin lifter 8,
The motor M is driven in the normal direction before the peg 8a of 8 moves upward to a position corresponding to the bottom of the bobbin B. When the motor M is driven in the normal direction, the support shaft 14 is rotated in the clockwise direction in FIGS. By the rotation of the support shaft 14, the guide arm 16b is rotated in the clockwise direction integrally with the lever 15a via the lever 15a and the torsion spring 21, and the guide arms 16a, 16c, 17a are connected to each other by the connection angle 20. .About.17c are rotated integrally with the guide arm 16b in the same direction. When the guide arms 16a to 16c and 17a to 17c are rotated to the horizontal position shown by the solid line in FIG. 1, the lower surface of the connecting angle 20 is engaged with the stopper bolt 22 screwed to the support brackets 13a and 13b. However, even if the support shaft 14 is rotated thereafter, each guide arm 16a to 16a
c, 17a to 17c are held in a horizontal position.

While the guide arms 16a to 17c move from the retracted position to the horizontal position, the pin 29 is held at the position shown by the solid line in FIG. 4 by the wire 34 against the elastic force of the tension spring 32, and each guide member 27a, 27b. Is arranged at a position extending parallel to the guide arms 16a to 17c. Therefore, when the bottom of the bobbin B suspended from the bobbin hanger 4 is displaced in the longitudinal direction of the transport rail 3 as indicated by P in FIG.
While the 27a is moved to the horizontal position, the tip end portion bent outward is brought into contact with the outer peripheral surface of the bobbin B, so that the guide member
With the movement of 27a, the bobbin B is moved to the position indicated by Q in FIG.

After the guide arms 16a to 17c are arranged at the horizontal position, the forward rotation of the motor M is further continued and the support shaft 14 is further rotated. At the time when the guide arms 16a to 17c are in the horizontal state, the ends of the wires 34 wound around the pulleys 33 are at the positions indicated by A1 in FIG. When the support shaft 14 is rotated clockwise from this state, the pulley 33 is relatively rotated with respect to the guide arms 16a to 17c, and one end of the wire 34 is moved from the point A1 to the point A2.
The pin 29 is moved to the right side, and accordingly, the pin 29 is moved to the right in FIGS. 4 and 5 by the elastic force of the tension spring 32. As the pin 29 moves to the tip side of the guide arms 16a to 17c, the guide members 27a and 27b are supported by the columns 26a and 26 via the link plates 30a and 30b.
The tips of the bobbins B are rotated inwardly with respect to each other around b, and the bobbin B located at the position 0 in FIG. 4 is guided into the fork 19 as the guide members 27a and 27b rotate.
The center is moved to the center of the bobbin hanger 4, that is, the position corresponding to the peg 8a of the empty bobbin lifter 8. When the empty bobbin lifter 8 is moved up in this state, each peg 8a is surely inserted into the hole at the bottom of the bobbin B and is moved up to a position where the bobbin hanger 4 releases the hooked state of the bobbin B.

The motor M is reversely driven before the empty bobbin lifter 8 starts the downward movement, and the reverse rotation of the motor M causes the support shaft 14 and the pulley 33 to rotate counterclockwise in FIG. As a result, one end of the wire 34 is rotated from the A2 point to the A1 point, and the pin 29 is moved leftward with the movement of the wire 34 against the elastic force of the tension spring 32, and via the link plates 30a, 30b. The guide members 27a, 27b are the columns 26a,
The tip end portion is rotated outward around 26b and is arranged at the position shown by the solid line in FIG. Lever at this point
When the stopper bolt 22 on 15a, 15b abuts the lower surface of the connecting angle 20 and the motor M is further driven in the reverse direction, the spindle 14
Together, the levers 15a and 15b are rotated counterclockwise, and the levers 15a and 15b push up the connecting angle 20 and the guide arms 16a.
.About.17c are rotated counterclockwise integrally with the levers 15a and 15b. Then, the motor M is stopped at the time when it is moved to the retracted position shown by the chain line in FIG. 1, and the guide arms 16a to 17c are stopped and held at the same position. Next, the empty bobbin lifter 8 is moved down, and the bobbin B is removed from the bobbin hanger 4.

Second Embodiment Next, a second embodiment will be described with reference to FIGS. In the above embodiment, the guide arms 16a to 16a are used as the driving device for the pin 29.
Although the support shaft 14 serving as the drive device for 7c was also used, this embodiment differs from the above-mentioned embodiment in that a single drive device for driving only the pin 29 is provided. That is, an air cylinder 35 is fixed on the connecting angle 20, and a bar 36 that extends parallel to the connecting angle 20 and is slidable along the upper surfaces of the guide arms 16a to 17c is connected to the tip of the piston rod 35a. There is. One end of each wire 34 is fastened to the pin 29 and the other end of each wire 34 is fastened to the bar 36.
A guide pin 37 for guiding the wire 34 is provided in each guide hole 18.

Therefore, in the apparatus of this embodiment, the guide members 27a and 27b are arranged at the positions shown by the solid lines in FIG. 4 with the piston rod 35a of the air cylinder 35 arranged at the projecting position, and the piston rod 35a is in the retracted state. When it is held at the position shown in FIG. In this way, when the pin 29 is driven independently of the rotation of the support shaft 14, each guide arm 16a
The levers 15a and 15b and the torsion spring 21 can be omitted by fitting and fixing the members 17c to the support shaft 14 so as to be integrally rotatable.

Third Embodiment Next, a third embodiment will be described with reference to FIG. In both of the above embodiments, the pair of guide members 27a, 27b are connected by the pair of link plates 30a, 30b, and the base ends of the link plates 30a, 30b move back and forth via the pin 29 to guide the guide member 27.
Although a and 27b are opened and closed, in this embodiment, the guide arm 38
A fork part 38a is integrally formed at the tip of the fork part 3a.
A guide member 39 is rotatably supported by a shaft 39a on one side of 8a. An electromagnetic coil 40 is disposed on the fork portion 38a at a position rearward of the shaft 39a so as to be orthogonal to the guide arm 38. On the other hand, a permanent magnet 50 is fixed to the guide member 39 at a position corresponding to the electromagnetic coil 40. Therefore, in the device of this embodiment, by reversing the direction of the current passed through the electromagnetic coil 40, the N-S of the magnetic pole is reversed, and the attractive force or repulsive force acts between the permanent magnet 50 and the permanent magnet 50. And
When the suction force acts, the guide member 39 is held in the open state shown by the solid line in FIG. 8, and when the repulsive force acts, it is arranged at the closed position shown by the chain line.

It should be noted that the present invention is not limited to the above-described embodiments, and for example, instead of the configuration in which the guide arms 16a to 17c, 38 are pivotally arranged between the retracted position and the working position,
16a to 17c and 38 are arranged to be moved to a retracted position and an operating position by horizontal movement, and not limited to a roving machine tube changer, JP-A-58-81631 and JP-A-61-119728. The present invention may be applied to a bobbin removing device for removing a bobbin from a bobbin hanger by pushing up the bottom part of a bobbin suspended from a bobbin hanger such as an automatic spinning machine for spinning machines disclosed in the official gazette.

As described above in detail, according to the present invention, the bobbin is tilted due to the positional deviation, the tilt, the tilt of the bobbin hanger itself, or the state of the hooking hook of the bobbin hanger, which causes the bobbin to tilt. Even if the bottom position shifts, the bobbin bottom position shift is corrected before the bobbin removal device moves up to the fitting position with the bobbin bottom position, and the bobbin bottom position corresponds to the bobbin removal device support. Therefore, the bobbin can be reliably removed by the bobbin removing device, which is an excellent effect.
