Description

[Detailed Description of the Invention] The present invention relates to a bobbin feeding vehicle in an automatic wine gourd.

In an automatic wine goo with a large number of winding units installed in parallel, once a predetermined amount of thread has been wound in each unit, a doffing operation is performed to remove the fully wound package from the bobbin holder, and a bobbin insertion operation is performed to supply a new empty bobbin to the holder. The winding operation is performed and winding is started again.

Such bobbin replacement work needs to be done quickly in order to increase the operating rate of the unit.

The present invention specifically provides an automatic bobbin feeding device for automatically feeding bobbins for this purpose.

That is, instead of providing a bobbin supply device for each winding unit, the bobbin is stored in a moving vehicle that runs along the winding unit, and the bobbin is supplied to the unit that has a bobbin request command. In particular, the present invention provides a cutting device suitable for cutting out a bobbin from a bobbin box of a moving vehicle that accommodates the bobbin.

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

In Fig. 1, reference numeral 1 denotes an automatic wine goo having a large number of winding units 2 arranged in parallel, and each unit 2 includes a cradle arm 3 that supports a winding package, and a traversing drum 4 that traverses the yarn and contacts and rotates the package. The unit is equipped with a yarn supply magazine 5 for supplying the yarn to the bed at the bottom of the unit, and winding is performed by known means.

A shelf or belt conveyor 7 for storing or transporting the full packages 6 is disposed behind the unit.

A ceiling rail 8 is provided above the unit along the unit.
, 8 are laid, and a bobbin supply vehicle 10 is suspended from the rails 8, 8 via wheels 9.9.

The moving vehicle is equipped with a bobbin box 11 that accommodates a large number of bobbins, and a bobbin cutting device that cuts out one bobbin from the bobbin box, and the cut bobbin is held by a bobbin insertion device (not shown). is supplied and inserted into the cradle arm.

The bobbin box 11 has an accommodating section 12 that accommodates a large number of bobbins 13 and an inclined passage 13 for aligning and moving bobbins 13 from the accommodating section to the cutting section. When a new bobbin is supplied to the bobbin box 11, the bobbin box 11 is rotated clockwise in FIG. 1 about the shaft 14 and positioned at a lower position.

The cutting device and the passage 13 of the bobbin box are shown.

In FIGS. 3 and 4, an approximately shaped bobbin receiving plate 15.15 is fixed to the rotating shaft 14 inwardly from both ends of the bobbin 13, and a shaft 16 is connected and supported between the receiving plates 15, 15. A U-shaped bracket 18 having an empty bobbin holding plate 17 fixed to its back surface is loosely fitted onto the shaft 16.

A spring 19 is wound around the shaft and constantly biases the bracket 18 in a clockwise direction about the shaft 16 in FIG.

The L-shaped receiving surface 15a of the bobbin receiving plate 15 is normally located at a position continuous with the lower surface 20 of the bobbin transfer passage 13, and the holding plate 17
A long pin 22 protrudes and is fixed onto the holding plate 17 so as to be continuous with the upper surface 21 of the passage 13 or positioned above the upper surface 21 of the passage, and the protruding portion of the long pin 22 engages with the bobbin box side wall 23. It is stopped and positioned against the spring 19.

Further, stop plates 24.24 are loosely fitted and supported on both sides of the receiving plates 15, 15 of the shaft 14 so as to be able to freely rotate around the axis, and the stop plates 24.24 are fitted with pins fixed to the side walls 23.23 of the box. Spring 26.26 connected to 25.25
The lower ends are connected, and the stop plates 25, 25 are always urged in the direction of arrow A in FIG.

A plate 27 is fixed between the bottom surfaces of the stop plates 24 and 24, and normally a spring 27 is attached as shown in the third figure.
The biased plate 27 on the lower surface of the stop plate 24 is positioned by coming into contact with the lower surface of the bobbin receiving plate 15 from below.

At this time, the front surface 24a of the stop plate 24 is located below the lower surface of the passage 20 and does not prevent the bobbin on the passage from entering the receiving plate 15.

Therefore, when cutting out the bobbin B1 that has entered the bobbin receiving plate 15 from the passage 13, the ron 28 shown in the fourth figure is actuated by a cam plate (not shown) provided on the moving vehicle, and the rotating shaft 14 is moved through the lever 29. Rotate by a certain angle in the direction of arrow C in Fig. 3.

A receiving plate 15 fixed to the shaft 14 by rotation of the shaft 14,
15 turns in the direction of the arrow and reaches the position shown by the two-dot chain line 15a.

At this time, after the long pin 22 is detached from the upper surface of the side wall 23, the holding plate 17, which rotates integrally with the receiving plate 15, grips the bobbin B1 by the force of the spring 19 shown in the fourth figure, so that the bobbin B1 does not fall. It is cut out and transferred to the position indicated by the two-dot chain line.

Furthermore, when the receiving plate 15 rotates, the stop plate 24 is driven by the spring 26 and rotates, but the protrusion 30 of the plate 27 fixed to the lower surface of the stop plate 24
The stop plate 24 engages with the passage lower surface 20 from below.
is positioned and stopped at a position indicated by the two-dot chain line 24b in FIG. 3, that is, at a position protruding above the passage.

Therefore, the bobbin B in the passage 13 comes into contact with the front surface of the stop plate 24b at this position, and is prevented from falling from the passage.

Further, the stop plate 24 acts to prevent the bobbin at the end of the passage from falling when the bobbin box 11 is rotated to the bobbin supply position.

That is, in FIGS. 3 and 4, when the bobbin box is rotated about the shaft 14 in the direction of arrow E, the passage 13 also rotates integrally with the bobbin box, so that the lower surface 20 of the passage is rotated by the plate protrusion 30 of the stop plate 24. After this engagement, the passage 13 and the plate protrusion 30 are rotated together, so that the front surface 24a of the stop plate 24 rotates while maintaining the state in contact with the bobbin B, and the passage 13 passes through the horizontal position, the passage is inclined in a direction opposite to the direction of inclination shown in FIG. 3, and the bobbin in the passage moves toward the receiving part of the box (FIG. 1, 12).

FIG. 5 shows the state in which the bobbin box 11 has been rotated and positioned at the bobbin supply position as described above.
Grasp the handle 31 shown in the second figure and pull it out to rotate the bobbin box about 90 degrees.
The position is as shown.

By opening the opening/closing door 32 on the side of the box at this position, the bobbin B can be easily replenished from the side of the box.

When the bobbin box 11 supplied with a predetermined amount of bobbins is reversely rotated and returned to its original position, it becomes the normal bobbin supply position.

At this time, after the passage 13 has passed through the horizontal position, the passage end opening is inclined so as to face diagonally downward, but the bobbin in the passage falls because the stop plate 24 returns to its original state in contact with the passage lower surface 20. The normal bobbin supply position can be taken without any trouble.

Note that when rotating the bobbin box, the shaft 14 shown in the third figure
does not rotate, the bobbin receiving plate 15 remains at the solid line position. Therefore, when the bobbin box 11 is rotated to its original position, after the plate 27 of the stop plate 24 engages with the lower surface of the receiving plate 15, the stop plate 24 stops at the position, and only the bobbin box 11 rotates, so the stop plate 24
The contact relationship between the front surface of the bobbin B and the bobbin B is released, and the bobbin B
will enter between the bobbin receiving plate 15 and the holding plate 17, which are waiting.

As described above, in the present invention, an inclined bobbin passage is provided in the bobbin box of the moving vehicle, and a receiving plate that pivots between a position for receiving the bobbin from the passage and a position for winding the hobbin is pivotally supported on the moving vehicle. A stop plate is rotatably supported on the lower surface of the receiving plate, and comes into contact with a spring biased from below, so that when the receiving plate receives the bobbin and rotates to the winding position, the stop plate will stop. The plate also rotates following the spring force, and stops at the position where the plate fixed to the bottom surface of the stop plate comes into contact with the bottom surface of the bobbin passage.The stop plate can come into contact with the bobbin at the end of the passage, and the cut bobbin is removed. Only one bobbin can be cut out without the subsequent bobbins falling from the passage.

Furthermore, when the bobbin box is rotated to the bobbin replenishment position, the lower surface of the bobbin passage abuts and engages the protrusion of the plate of the stop plate from above, positioning the stop plate at the end of the passage and integrating the box and stop plate. Since the bobbin box is rotated in a fixed manner, the bobbins in the passage do not come into contact with the stop plate and fall from the passage even when the box is returned to its original position after bobbin supply to the bobbin box.
