BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bobbin conveying device equipped with a dispensing device for dispensing a yarn end of a spinning bobbin or the like and supplying it to a winder or the like.

[0002]

2. Description of the Related Art When a spinning bobbin produced by a spinning machine is supplied to each winding unit of a winder, a spinning process is performed so that the yarn end can be easily caught.

An example of this feeding device is Japanese Patent Laid-Open No. 61
There is one disclosed in Japanese Patent Publication No. 155171.

[0004]

By the way, at the start of operation of the winder, it is necessary to flow empty bobbins or empty trays in order to flow a predetermined number of trays on the transfer line. When the actual bobbin and the empty bobbin are mixed, the conventional dispensing device cannot selectively bypass only the empty bobbin.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to solve the above problems and to provide a bobbin transport system equipped with a dispensing device capable of dispensing only the bobbin to be dispensed and improving the dispensing processing efficiency.

[0006]

In order to achieve the above object, the present invention is to connect a lead-out transfer path in the middle of a tray transfer line separately from the tray transfer line to connect the tray transfer line and the lead-out transfer path. The separating unit is provided with a dispensing device characterized in that a bobbin to be dispensed is provided and a sorting device is provided for determining whether the bobbin should be taken into the dispensing transport path or to be flown to the tray transport line and sorts it. .

[0007]

According to the above construction, the tray transfer line is connected to the lead-out transfer path, and the discriminator provided on the upstream side of the connection portion determines whether or not the tray should be taken into the lead-out transfer line. A bobbin that can be rewound by a winder, such as a half-ball bobbin, or a bobbin that cannot be rewound by a winder, such as a bobbin with an extremely small amount of residual thread, or an empty bobbin, and the actual bobbin, etc. By letting the bobbin or the like flow through the transport line as it is, the empty bobbin or the like does not flow in the feeding transfer path, and the feeding efficiency can be improved.

[0008]

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

First, referring to FIG. 3 and FIG. 4, description will be given of a feeding device A having an air flow control means of the present invention.

In FIGS. 3 and 4, reference numeral 1 denotes a bobbin for feeding, which is erected on the transfer tray T and is transferred through the feeding passage 2 and stopped at a feeding position P by a stopper (not shown). A discriminating device for discriminating whether or not the bobbin is rewound by a winder is provided on the upstream side of the feeding position P of the feeding passage 2 for feeding. It is determined that the bobbin with the minimal residual thread, the empty bobbin, and the empty tray cannot be rewound.

A tray sensor 4 for detecting the tray T is provided near the stop position.

Corresponding to the output position P, the output device main body U
Is erected. In the body U of the dispensing device, a cylindrical body 5 is provided above the bobbin 1 stopped at the dispensing position P so as to be vertically movable as an air flow control means. An expandable bellows hose 6 is connected to the upper part of the cylindrical body 5, the hose 6 is connected to a shutter cutter 7, and an outlet pipe 8 of the shutter cutter 7 is connected to a suction pipe 9 connected to an air flow generating means. To be done.

An arm 10 is attached to the cylindrical body 5,
The arm 10 passes through the slit 11 of the device body U,
A vertical guide rod 12 provided in the main body U is provided so as to be movable up and down, and a fixed plate 13 of the rod 12 is provided with an arm 10.
An elevating cylinder 14 that moves up and down is provided.

The arm 10 is provided with a bobbin detection sensor 16 for detecting the chess portion 15a of the thread layer 15 of the bobbin 1. Based on the detection value of the bobbin detection sensor 16 and the like, the ascending and descending electromagnetic valves 17a, b is turned on and off to operate the lifting cylinder 14 to move the cylinder 5 up and down.

The shutter cutter 7 includes upper and lower plates 7a and 7a.
b, a hole 18 for communicating the bellows hose 6 with the outlet pipe 8
a and 18b are formed, and a movable shutter 19 that opens and closes the holes 18a and 18b and cuts the yarn passing through the holes 18a and 18b to a fixed length is provided, and the movable shutter 19 is opened and closed by a shutter actuator 20. .

A V-shaped guide 21 for guiding the sucked yarn end to a predetermined position is provided on the inward side of the bent portion of the sion pipe 9, and the spout detecting sensor is positioned at the yarn path YP. 22 is provided, and the shutter cutter electromagnetic valve 23 that operates the shutter actuator 20 is operated by the output of the sensor 22.

A bunch removing blast nozzle 25 for removing the top bunch 24 on the upper portion of the bobbin 1 is provided in the dispensing device body U, and a blast electromagnetic valve 26 for intermittently supplying air to the blast nozzle 25 is provided. To be The blast nozzle 25 is used only for the bobbin 1 of the top bunch 24, and is not used for the bottom bunch.

Above the bobbin 1, there is provided a head pressing lever 27 for pressing the yarn unwound from the bobbin 1 and sucked by the suction pipe 9 onto the bobbin 1, and the actuator 2
At 8, the head pressing lever 27 is operated so as to come into contact with and separate from the head of the bobbin 1.

At the outlet position P, the bobbin 1 is prevented from slipping out of the tray T when the bobbin 1 is extended, particularly when the bobbin 1 is unwound by the tubular body 5 of the air flow control means. A bobbin pressing lever 29 and an actuator 30 for pressing the bobbin pressing lever are provided for pressing the unwound portion of the lower part.

As shown in FIG. 4, the feeding passage 2 is provided along a round belt 31 for transporting the tray T and both sides of the round belt 31, and receives and guides both sides of the bottom portion of the tray T. The bottom guide plate 32 and the peg portion 3 of the tray T
It is composed of an upper guide plate 34 for regulating and guiding 3. A suction pipe 35 is provided below the tray transport path at the feeding position P to draw the cut fixed-length yarn into the bobbin 1 when the cutter shutter 7 cuts the fixed-length yarn. The upper end opening of the suction tube 35 is directed to the center of the lower surface of the tray T at the feeding position P. A suction hole suction shutter 35a is provided in the middle of the suction pipe 35, and the shutter 35a is opened and closed by a solenoid 35b. Further, on the upper guide plate 34 at the feeding position P, yarn blowing nozzles 60 are provided at both side positions sandwiching the bobbin 1. Each nozzle 60
Has two injection ports 61a for injecting blast air obliquely upward toward the bobbin 1 and obliquely downward. By the blast air, for example, a thread hung from the thread layer 15 of the bobbin 1 is moved to the bobbin pressing lever 29. It is designed to be blown away from the bobbin holding area.

Next, the lead-out operation will be described.

Before the tray T is moved along the transfer path 2 to the feeding position P, whether or not the tray T is a bobbin which can be rewound by a winder by a discriminating device (not shown), that is, whether or not the feeding is necessary. To be determined. When the ejection is not necessary, for example, in the case of a minimal residual yarn bobbin, an empty bobbin, an empty tray on which the bobbin is not placed, the ejection operation is not performed by the ejection device, and the tray T and the ejection device are passed. On the other hand, in the case where it is necessary to take out the mouth, for example, in the case of a full bobbin, a half bobbin, a bean bobbin, etc., the following lead out operation is performed. That is,
When the tray T is conveyed to the lead-out position P, the tray is stopped at the lead-out position P by a stopper (not shown). When the tray sensor 4 detects the tray T, blast air is jetted from the yarn blowing nozzle 50, and then the bobbin pressing lever 29 (solenoid 28) is operated to press the lower part of the bobbin 1 by the tip of the lever 29. . Therefore, as will be described later, the bobbin 1 does not come out of the tray T even if the suction force acts on the bobbin 1.
Since air is blown from the nozzle 60 before the bobbin 1 is pressed by the lever 29, it is possible to prevent the yarn end from being caught between the lever 29 and the bobbin 1. Simultaneously with the operation of the lever 29, the actuator 20 is operated, the shutter cutter 7 is opened, the suction pipe 9 and the tubular body 5 are brought into communication with each other, and an airflow toward the inside of the tubular body 5, that is, a suction force is generated, and the thread of the bobbin 1 is generated. An air flow that rises along the surface of the layer and heads into the cylindrical body 5 is generated.

The operation thereafter is different between the case of the bobbin with the bottom bunch and the case of the bobbin with the tob bunch, so the case of the bottom bunch will be described first. In the case of a bottom bunch, a bottom bunch cut station is provided on the upstream side of the lead-out position P.

After the shutter cutter 7 is activated, the tubular body 5 begins to descend after a short time. However, if the yarn end of the bobbin 1 is sucked into the suction pipe 9 through the tubular body 5 and the lead-out detection sensor 22 detects that the yarn end is sucked in the short time, the tubular body 5 Does not fall. When the tubular body 5 descends, the tubular body 5 and the bobbin 1 gradually approach each other, so that the air flow acting on the bobbin thread layer is strengthened. If the yarn end detection sensor 22 detects the yarn end while descending, the tubular body 5 immediately rises. Sensor 22
If the yarn end is not detected at, the tubular body 5 descends to a position (the lower end of the stroke) that substantially surrounds the entire bobbin 1. Cylinder 5
After descending to the lower end of the stroke, the robot subsequently moves up. If the yarn end is not detected by the sensor 22 by the time the cylinder 5 finishes ascending to the upper end of the stroke, the cylinder 5 performs the lowering operation again. The lowering and raising of the cylinder 5 are repeated three times,
If the sensor 22 still does not detect the yarn end, the stopper (not shown) is released, and the tray T is dispensed from the dispensing position. The number of times of lowering and raising the cylindrical body 5 may be only once, or may be four times or more. It should be noted that the blast air of the yarn blowing nozzle 60 is stopped during the period in which the tubular body 5 starts to rise and then falls. This can be easily done by receiving signals from the electromagnetic valves 17a and 17b.

When the thread end is detected by the sensor 22 and the cylindrical body 5 rises and reaches the upper end of the stroke, this is detected by a sensor (not shown), and the head pressing lever 27 is operated to contact the head of the bobbin 1. , The thread connected between the bobbin 1 and the suction pipe 9 is pressed to stop the thread release. Alternatively, the head pressing lever 27 may be operated when the cylinder body 5 is raised to a predetermined height without setting the stroke upper end. The point is that the cylindrical body 5 and the lever 27 should not interfere with each other. Simultaneously with the operation of the solenoid 28, the solenoid 35
b also operates, the top hole insertion suction shutter 35a opens, and the suction force acts toward the inside of the bobbin 1.

After that, the actuator 20 is operated to close the shutter cutter 7, and the yarn connecting the bobbin 1 to the suction pipe 9 is cut by the shutter cutter 7. The yarn end connected to the cut bobbin 1 is sucked into the bobbin 1 by the suction force of the suction tube 35. Bobbin one by one
Since the distance from to the shutter cutter 7 is set shorter than the length of the bobbin 1, the yarn end sucked into the bobbin 1 does not pass through the tray T and extend to the suction tube 35.

Then, the solenoid 28 is actuated, the head pressing lever 27 is returned to its original position, and the bobbin pressing lever 29 is moved.
Returns to the original position and the suction shutter 35a closes. After that, the stopper holding the tray T is released, the tray T is discharged from the feeding position P, and is supplied from the transfer path 2 to each winding unit of the winder.

Next, the case of a bobbin having a top bunch will be described. In the case of a top bunch, after the shutter cutter 7 is activated, first the bunch removal blast nozzle 2
Blast air is jetted from 5 toward the bunch winding portion of the bobbin 1 for a predetermined time. Subsequently, the tubular body 5 starts to descend, and thereafter, the same operation as in the case of the bottom bunch is performed.

It is also possible to do the following.
That is, the chess portion 1 of the thread layer 15 of the bobbin 1 is attached to the arm 10.
The bobbin detection sensor 16 for detecting 5a is provided, and the cylindrical body 5 is lowered based on the detection value of the sensor 16. In this case, regardless of the detection by the sensor 22, the tubular body 5 is lowered until the sensor 16 detects the chess portion 15a. After that, the cylinder 5 may be raised when the sensor 22 detects the yarn end, or may be raised when a predetermined time has elapsed. As described above, the method of lowering the tubular body 5 while looking at the chess portion 15a is as follows.
It is preferably used in the case where the shape is along the chess portion as in (b), (c) and (d).

In the above-mentioned embodiment, the sensor 22 for detecting the lead-out is detected.
When the yarn end is detected by, the cylinder body (air flow control means) 5 is moved up (retracted) and then the next operation (operation of the shutter cutter, etc.) is performed. The next operation may be performed as soon as the yarn end is detected. Alternatively, when the yarn end detection sensor 22 detects the yarn end, the tubular body 5 may be stopped first, the shutter cutter 7 may be operated, and then the tubular body 5 may be raised. Further, instead of providing the means for inserting the thread end into the hole of the bobbin 1, a means for winding the thread end around the head of the bobbin 1 or a means for fixing the thread end on the thread layer of the bobbin 1 may be provided. The suction pipe 9 and the tubular body 5 may be continuous or may be divided. The bobbin pressing means may be, for example, a plunger that moves forward and backward with respect to the bobbin or the end portion by a solenoid, in addition to the swinging lever.
