Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package discharge device for use in a take-up winder having a bobbin holder on which a large number of packages are mounted and which is rotatably projected.

[0002]

2. Description of the Related Art First, a spinning winder to which this type of package discharge device is applied will be described with reference to FIGS. 2 is a side view of the take-up winder, and FIG. 3 is a front view of the take-up winder. The take-up winder 1 has a horizontal shaft 3 with respect to the main body frame 2.
A turret disk 4 rotating around the turret disk 2, two bobbin holders 5 and 6 protruding from the turret disk 4, and an induction motor 7 fixed to the back side of the turret disk 4 to drive the bobbin holders 5 and 6 in rotation. , 8 and a detection roller 1 provided on an elevating frame 9 which is vertically movable with respect to the main body frame 2.
0 and a traverse device 11 for yarns, which is also provided on the elevating frame 9, and the elevating frame 9 bears a load by an air cylinder 12 provided on the base end side thereof.
The pressure difference between the weight and the lifting force of the air cylinder 12 is the contact pressure of the detection roller 10 against the package. B is a bobbin and P is a package formed by winding a thread around the bobbin B. The two bobbin holders 5 and 6 can be switched by rotating the turret disc 4 by 180 degrees by a drive source (not shown).

When winding onto the bobbin B on one bobbin holder 6 is completed and the package P is formed, the turret disk 4 rotates clockwise, and the package P is positioned on the lower side as shown in the figure. On the contrary, the other bobbin holder 5 in which the empty bobbin B has been inserted is positioned on the upper side, and the winding of the new empty bobbin B is started again. By the way, it is necessary to discharge the package P from the bobbin holder 6 and mount a new empty bobbin B until the next package is formed.

Therefore, conventionally, as shown in FIG. 2, a cylinder 13 is arranged below the main body frame 2, and the cylinder 13
The plate 14 that comes into contact with the end surface of the bobbin B is provided at the tip of the
A package ejection device is provided that pushes out the package P as the air cylinder 13 extends. A package pushed out by such a conventional package discharge device is usually automatically conveyed by a doffing device.

The structure and operation of the doffing device will be described with reference to FIG. Since a large number of the above-described spinning winders 1 are arranged in parallel, the common doffing device 20 is movably arranged on the rail 15 laid along the spinning winder 1. That is, the doffing device 20 is located in front of the take-up winder 1 having the package P, and receives the package P and supplies the empty paper tube. Note that FIG. 4 illustrates the package receiving mechanism and omits the empty paper tube feeding mechanism. The doffing device 20 includes a plate 22 that is slidable on the carriage 21 toward the take-up winder 1, and a support shaft 24 that projects from a column 23 that is erected on the plate 22. The support shaft 24 is the bobbin holder 6 of the take-up winder 1.
When the plate 22 is slid forward, the support shaft tip 24A and the bobbin holder tip 6A are engaged with each other.

The operation of the doffing device 20 will be described. First, as shown by the arrow, the doffing device 20 travels to the take-up winder 1 having the package P. As shown by the arrow, the plate 22 slides forward, and the support shaft tip 24A
Engages with the bobbin holder tip 6A. Like the arrow
The cylinder 13 extends and the plate 14 pushes the bobbin B end surface to push the package P to the support shaft 24. Then,
The plate 22 slides backward (see the arrow) to release the engagement between the support shaft tip 24A and the bobbin holder tip 6A,
The doffing device 20 travels to the package collection site (see arrow). The cylinder 13 of the take-up winder 1 has returned to its original state (see arrow).

[0007]

By the way, the above-mentioned conventional package discharging device is one in which all the packages P mounted on the bobbin holder 6 are pushed out by the air cylinder 13 at once, and the supporting shaft of the doffing device 20. Twenty-four receive all packages at once. However, in recent years, the bobbin holder 6 has become longer (more bobbins), and a bobbin holder 6 having a total length of about 2 meters has been manufactured. Therefore, the width W of the doffing device 20 is also longer than the bobbin holder 6, and the traveling space of the doffing device 20 is required to be large. Therefore, the doffing device 20 has two support shafts 24, for example, an upper and a lower support shaft 24, which are rotatable in a vertical plane.
A system for receiving all packages in two has also been considered. However, the conventional package discharge device using the air cylinder 13 has a problem that it cannot be pushed out in a divided manner.
Further, as described above, there is a spin winding machine that uses one bobbin holder, instead of the type of a spin winding machine that automatically switches between a package and an empty bobbin between two turret type bobbin holders. In such a take-up winder, the operator may do the doffing of the packages P one by one, and the discharging device using the air cylinder 13 cannot push out the packages P one by one.

The present invention has been made in view of the above problems of the prior art, and its object is to provide a spinning winder capable of extruding an arbitrary number of one or more packages. It is to provide a package ejection device.

[0009]

SUMMARY OF THE INVENTION A package ejecting device for a take-up winder according to the present invention, which solves the above-mentioned problems, is used in a take-up winder having a bobbin holder, on which a large number of packages are mounted, projecting rotatably. The discharging device includes advancing / retreating means capable of pushing out a predetermined number of the packages to stop it, and control means for directly or indirectly detecting the prescribed number of packages to determine the stop position of the advancing / retreating means. It is a thing.

[0010]

For example, when it is desired to push out packages one by one, the control means detects one package and issues a stop command to the advancing / retreating means. The advancing / retreating means can be stopped at a predetermined position, such as a trapezoidal screw ball screw, and can push out an arbitrary number of packages based on a command.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a package discharge device of a take-up winder according to the present invention.

The spinning winder shown in FIG. 1 differs from the spinning winder of the type described in the prior art in which two bobbin holders are projected on a rotating turret disk to alternately wind the spinning yarn. It is a type of take-up winder in which the bobbin holder winds up the spinning thread, and when the bobbin is full, the winding is stopped once (spinning is sucked up by the suction gun), and the package and the empty bobbin are replaced and mounted. FIG. 1 shows an example in which the package discharge device of the present invention is applied to a spin winder of this type.
Will be described.

First, the structure will be described. In FIG. 1, the take-up winder 41 includes a bobbin holder 46 on a main body frame 42.
And, a frame 49 is projected above it. The bobbin holder 46 is loaded with a plurality of packages P and is driven to rotate by a drive motor (not shown) to wind up the yarn. A pusher 43 that pushes out the bobbin B is disposed further inside the bobbin B of the innermost package P. The pusher 43 is installed below the bobbin holder 46 in parallel with each other on the main body frame 42. The guide bar 44 and the trapezoidal screw 45 are fitted and attached. The trapezoidal screw 45 and the fitting hole 43a of the pusher 43 are threaded, and the pusher 43 is moved in the axial direction by rotating the trapezoidal screw 45 by the drive motor 51 connected to one end of the trapezoidal screw 45. It is like this. The guide bar 44 prevents the pusher 43 from rotating and is slidable. The drive motor 51, the trapezoidal screw 45, and the guide bar 44 constitute a means for moving the package P forward and backward.

A pusher 4 is provided near the base end of the trapezoidal screw 45.
An in-situ sensor 48 is provided for detecting that 3 has returned to the origin, and a return sensor 47 for detecting that the pusher 43 has reached the tip of the trapezoidal screw 45 is provided near the tip. Limit switches and the like are used for the original position sensor 48 and the return sensor 47. Furthermore, the tip of the bobbin holder 46 is at the take-out position of the package P, and above the take-out position, that is, the frame 4
A package detection sensor 52 for detecting the presence or absence of the package P at the tip of the bobbin holder 46 is provided at the tip of the package 9. An infrared sensor or the like is used as the package detection sensor 52. Each of these sensors 47, 48, 52
And the drive motor 51 is a control circuit 5 including a CPU and the like.
The control circuit 50 controls the drive motor 51 by receiving inputs from the sensors 47, 48 and 52 as control means and calculating the inputs. Here, the control circuit 50 causes the drive motor 51 to rotate normally (in a direction in which the pusher 43 moves forward) while there is no input from the package detection sensor 52. Further, the input from the return sensor 47 causes the drive motor 51 to rotate in the reverse direction to return the pusher 43 to the original position. The drive motor 51 is stopped by the input from the original position sensor 48.

Next, the operation of the package discharge device of this spinning winder will be described. (1) When the desired package P is wound and formed, the package discharge operation is started by the signal 53 from the main body. At this time, since the pusher 43 is in the original position shown by the chain double-dashed line and the tip of the package P is at the winding position 46b, the package P does not exist at the taking-out position 46a. Therefore, since there is no input from the package detection sensor 52, the drive motor rotates in the normal direction, and the pusher 43 advances to push out the package P. (2) When the tip of the package P reaches the take-out position 46a, the package detection sensor 52 detects this and outputs a signal, and the drive motor 51 stops and the pusher 43 stops. (3) When the operator removes the package P in the front row, the input from the package detection sensor 52 disappears, so the pusher 43 advances and pushes out the package P. (4) Hereinafter, the operations of (2) and (3) are repeated. (5) When the operator takes out the last package P,
The pusher 43 advances as it is to the position of the return sensor 47, and when the return sensor 47 detects this, the drive motor 51 reversely rotates and the pusher 43 moves backward. Then, the home position sensor 48 detects the pusher 43, whereby the drive motor 51 stops, and the pusher 43 returns to the home position.

In the above description, the position (presence / absence) of the package P is directly detected by using the package detection sensor 52 to control the operation of the pusher 43. However, the package P is indirectly detected and the pusher 43 is detected. The operation of may be controlled. That is, for example, the position of the package P can be indirectly detected by connecting an encoder to the drive motor 51 and detecting the rotation angle of the motor 51. Further, in this case, if the array interval of the packages P is stored in the CPU in advance, it is possible to push out an arbitrary number of packages P from the package interval and the encoder input.

Further, as the advancing / retreating means, the above-mentioned screw 4 is used.
Instead of 5, etc., a type in which a pusher is attached to a chain wound around sprockets on both ends, a type using a servomotor or a magnet scale and a hydraulic cylinder, or the like may be used, and the same result can be obtained.

In the above description, the case where the package discharge device of the present invention is applied to the spinning winder of the type in which the single bobbin holder winds the spinning yarn and the package and the empty bobbin are exchanged and mounted is explained. The package discharge device of the present invention can be applied in the same manner to the spin winding machine of the type described in the prior art in which the two bobbin holders provided on the rotating turret disk alternately wind the spinning yarn. is there.

Further, the packages pushed out from the spinning winder are directly received by a tray having a horizontal peg shaft projecting from the tray, and the tray is conveyed by a conveyor. When the doffing device receives the entire package by dividing it into two, the package ejecting device of the take-up winder of the present invention is used.

[0020]

As described above, the package discharge device of the spinning winder of the present invention detects the position of the package directly or indirectly and pushes it out to a predetermined position. It can be applied to automation using a doffing device for receiving all packages in two, or automation for receiving packages one by one in a tray. Further, even when the operator takes out one by one, when the operator pulls out the package, the next package is automatically pushed out to the tip of the bobbin holder, which facilitates the work.
