Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bobbin pushing-out device for pushing a bobbin out of a bobbin holder by bringing a pushing member into contact with an end surface of the bobbin in a turret type spinning winder.

[0002]

2. Description of the Related Art In a take-up winder, a spun yarn is wound on a paper tube which is a bobbin supported by a bobbin holder which is rotationally driven by a motor to form a fully wound package. . In order to quickly exchange the formed full-wrap package and the empty paper tube, install another bobbin holder in a position parallel to the bobbin holder at the position where the yarn is wound, and support both bobbin holders on the turret plate, When the formation is completed, the turret plate is rotated, the positions of the bobbin holder that supports the full-wrapped package and the bobbin holder that supports the empty paper tube are exchanged, and the yarn is rewound on the empty paper tube and the full-wrapped package is removed from the bobbin holder. It is being discharged.

When the full-wrap package is discharged from the bobbin holder, all the full-wrap packages are discharged from the bobbin holder by pushing the full-wrap package in parallel with the axis of the pushing device provided at the base of the bobbin holder supporting the full-wrap package. .

[0004]

The pressing member of the extrusion device in the turret type spin winder as described above has a structure in which the turret plate is rotated to switch between the full winding package and the empty bobbin. It is necessary to make the size small enough not to interfere with the revolution trajectory of the bobbin holder that revolves around. Further, in consideration of mechanical error of the bobbin holder and deflection of the bobbin holder shaft due to the weight of the package, it is necessary to further reduce the pressing member that pushes the bobbin holder in parallel to the tip. As a result, conventionally, the pressing member pushes out a large number of full-wrap packages supported by the bobbin holder at a small area below the end surface of the paper tube which is the bobbin of the full-wrap package on the turret plate side. As a result, the end face of the paper tube is deformed or damaged, and the end face of the full-wrapped package is pushed out instead of the paper pipe, resulting in a defective product with a scratched end face of the package. Furthermore, since the paper tube is locally extruded with a strong force, there is a problem that twisting may occur between the bobbin holder and the bobbin of the full package, and the full package may not be reliably extruded.

According to the present invention, even if the turret plate is rotated,
A spinning winding that can smoothly and reliably push out a full winding package without contacting the bobbin holder that revolves when the turret plate rotates and eliminating defective products caused by damage to the paper tube and pushing out the package end surface. The purpose of the present invention is to provide an extruding device for a machine.

[0006]

In order to achieve the above object, the present invention is, in a bobbin pushing-out device in a take-up winder, an operating position in contact with an end face of the bobbin and a bobbin locus accompanying rotation of a turret plate. The position of the contact member can be freely changed over the stand-by position, and a mechanism for converting the pushing power of the bobbin into the position changing force of the pressing member is provided.

Further, it is preferable that the position changing operation is a sliding movement.

Further, the pressing member is composed of a base member and a moving member that engages with the end surface of the bobbin, and the converting mechanism pushes the moving member toward the working position. In order to pull back the moving member to the standby position side by connecting the elastic body, the base member and the moving member, and abutting against the body of the take-up winder when the pressing member is on the turret plate side. It is preferable that it is configured by the waist bending link member.

[0009]

In the bobbin pushing-out device of the spinning winder configured as described above, the pressing member is moved to a position where it comes into contact with the bobbin as the bobbin is pushed out. After the bobbin has been pushed out, the bobbin is returned to the standby position where it does not come into contact with the bobbin holder.

The pushing operation of the bobbin of the full package is used as the position changing force to the working position, and the movement of returning the bobbin to the turret plate side after the completion of pushing the bobbin is used as the position changing force to the standby position.

In the converting mechanism constituted by the elastic member attached to the lower end of the moving member and the upper end of the base member and the waist bending link member connecting the base member and the moving member, the waist bending link member is a spinning winder. By abutting on the main body, the wall of the main body of the take-up winder is utilized to pull back the moving member to the standby position side, and the elastic body works to urge the elastic member to project toward the working position side.

3 is a side view of the bobbin pushing device 13 of FIG.
FIG. 4 is a rear view of the main part of FIG. 4, and FIG. 4 and FIG. 5 are overall views of the take-up winder.

A winding machine using the extrusion device 13 of the first embodiment will be described with reference to FIGS. 4 and 5. This spinning winder 1 has a horizontal axis 3 with respect to the main body frame 2
Turret plate 4 that swivels by degrees, and the turret plate 4
Two bobbin holders 5 and 6 that cantilevered from the
Induction motors 7 and 8 fixed to the back side of the turret plate 4 to rotate and drive the bobbin holders 5 and 6, a touch roller 10 provided on an elevating frame 9 vertically movable with respect to the main body frame 2, and the elevating and lowering. The traverse device 11 provided on the frame 9 is mainly configured. The elevating frame 9 bears a load by a contact pressure cylinder (not shown) provided on the base end side of the elevating frame 9, and the pressure difference between the total weight of the elevating member and the lifting force of the contact pressure cylinder causes the contact roller 10 to contact the package. It comes to pressure. In addition, B
Is a paper tube which is a bobbin, P is a full winding package, and 14 is a pressing member.

The operation of the above-described spin winding machine will be described below. In FIG. 4, the bobbin holder 5 is in the winding position a, and the other bobbin holder 6 is in the standby position b. The package at the winding position a is wound up by a preset amount, and when the package is fully wound, the turret plate 4 turns 180 degrees,
On the contrary, the full package P becomes the standby position b, and the empty bobbin B becomes the winding position a. Then, as shown in FIG. 5, while the yarn Y is in contact with the bobbin B, the full package P
The yarn Y is transferred from the full winding package P to the empty bobbin B by a yarn passing device (not shown), and winding is started. Next, the rotation of the bobbin holder 6 at the standby position is stopped, and the pushing device 13 at the standby position is also pushed out in parallel with the axis of the bobbin holder by the operation of the cylinder 15, so that the pushing member 14 of the full package P is moved. The end surface of the bobbin B is pressed, the full-roll package P is pushed out to a doffing cart (not shown), and the empty bobbin B is inserted into the bobbin holder 6 at the same time. By repeating the above operation, the yarn is continuously wound.

The mechanism of the extruder will be described in detail below. 1 to 3, one end of the spring 19 is attached to a protrusion on the lower end of the U-shaped moving member 16 and the other end is attached to a protrusion on the upper end of the base member 17 whose upper end is a U-shaped notch as a tension spring. The shaft F pivotally supports the arm 18a on the bobbin holder side of the waist bending link member 18 and the notch of the base member 17. One groove 21 of the moving member 16 is fixed by a bolt 20 via a collar 26 with a collar and a washer 27 for preventing a shake at the time of movement so as to have the same axis as the shaft F and the other groove. 21 is fixed to the shaft F with a bolt 20 via a collar 28 so as to have the same axis center. Further, the other arm 18b of the waist bending link 18 and the moving member 16 are stopped with a bolt 22 so as to have a play, and the base member 17 and the groove 23 of the moving member 16 are further fixed.
Similarly, one side is collar 26 with washer and washer 27
Then, the other is fixed by the bolt 24 via the collar 28. At this time, the waist bending link member 18 is in a state of being bent toward the contact surface S side of the main body of the take-up winder.

With the above construction, as the pushing device 13 advances in the direction of B shown in FIG. 1 by the operation of the cylinder 15, it is located at the bent portion of the waist bending link member 18, and the movement of the waist bending link 18 is smooth. Roller 25
Is pressed against the contact surface S of the main body of the take-up winder, and the bent portion becomes linear. In other words, since the distances between the base member 17 and the arm 18a of the waist bending link 18 from the axis of the bobbin holder do not change, the bolt 20 serves as a fulcrum and the roller 25 serves as an action point. , Limited to the direction orthogonal to the axial direction of the bobbin holder. That is, the arm 18b of the waist bending link 18 moves in the direction away from the axis of the bobbin holder, and the moving member 16 connected by the bolt 22 also moves in the direction away from the axis of the bobbin holder, and finally the standby position. It becomes the state of 1.

On the contrary, as the pushing device 13 advances in the direction of (a) in the figure by the operation of the cylinder 15, the restoring force of the spring 19 causes the waist bending link member 18 to change from the straight state to the bent state, and the moving member 16 is moved to the direction shown in FIG. It moves in the direction approaching the axis of the bobbin holder as shown in 2, and moves to the working position where it engages with the end surface of the bobbin holder B. As a result, the bobbin B is brought into contact with the bobbin B of the full package P by the U-shaped moving member 16 capable of reliably pressing two positions corresponding to 180 degrees of the bobbin end face.

A second embodiment is shown in FIGS. 6 and 7. In the first embodiment, one tension spring 19 is provided on the back surface of the base member 17, but in the second embodiment, two tension springs 19 are provided between the base member and the moving member 16, so that the tension spring 19 is smoother. The feature is that it works.

In the above embodiment, in order to urge the moving member 16 to project to the operating position where it abuts on the end surface of the bobbin B,
Although the tension spring 19 is provided, the tension spring 19 is not limited to the tension spring 19 and may be implemented as follows.

For example, a compression spring may be provided between the upper end of the base member 17 and the upper end of the moving member 16, and the moving member 16 may be projected to the operating position by the action of this compression spring. For example, a small-diameter cylinder may be provided in place of the tension spring 19 and the compression spring that are typical elastic bodies, and the small-diameter cylinder may be connected in parallel with the pushing cylinder 15 by piping. In this case, the cylinder 15 for extrusion
The moving member 16 can be changed to the working position in association with the start of extension of the moving member 16, and the moving member 16 can be returned to the standby position in association with the start of retreating the cylinder 15 after the doffing is completed.

[0021]

According to the present invention, the following effects can be obtained. According to the present invention, since the pushing member can be changed in position between the working position and the standby position, a U-shaped pushing member that wraps around the left and right sides of the bobbin can be adopted. In other words, even if the contact area with the end surface of the bobbin is increased, the pressing member does not come into contact with the bobbin holder that revolves due to the rotation of the turret plate. As a result, the pushing member surely presses two points corresponding to 180 degrees on the end surface of the bobbin, and further the U-shape is formed in consideration of the deflection of the bobbin holder, thereby causing the twist between the bobbin holder and the bobbin. In addition, the end surface of the paper tube, which is the bobbin, is not deformed or damaged so that a defective product with a scratch on the package end surface is not generated.
It has become possible to smoothly and reliably push out a full-roll package.

Further, since it has a mechanism for converting the power for pushing out the bobbin of the full package to the position changing force of the pressing member, no special control for changing the position is required. . Therefore, it can be attached to the conventional take-up winder, and the machine currently in operation at the customer can be improved simply by replacing the pressing member. In particular, since it is a mechanism that uses power to push out a full-wrapped package, compared to a mechanism that eliminates the interference between the pushing member and the bobbin holder by the force of contact with the bobbin holder that revolves at a relatively high speed. There is no impact due to the collision of the two, and there is an effect that it works smoothly.

Further, in the case where the position of the pressing member is changed by sliding movement, it is easy to increase the receiving surface of the reaction force when the full-roll package is pushed out, and it is easy to make a sturdy structure. effective. Further, when the mechanism for converting the pushing force of the bobbin into the position changing force of the pressing member is constituted by the elastic body and the waist bending link, the bobbin trajectory is deviated by using the wall surface of the take-up winder. The timing for changing the position to the standby position can be determined, which has the effect of making the configuration simple.
