でその全てを省略する。Automatic doffing involves grasping the full bobbin fitted to the spindle with a gripper or other gripping tool, removing it from the spindle, transporting the removed full bobbin to a predetermined storage position, and then placing it back on the empty spindle. The process of transporting and inserting the empty bobbin held in the machine is carried out automatically.
There is a so-called simultaneous lifting method in which all spindles on one side of the spinning machine are doffed at the same time, a group lifting method in which multiple spindles are doffed as one unit, a method in which two sets of grippers process full bobbins and insert empty bobbins in parallel, Various grippers have been proposed and put into practical use, such as a gripper that alternately processes full bobbins and inserts empty bobbins. Regardless of which type of automatic doffing you use, it is important to reliably remove the full bobbin from the spindle, but empty bobbins that are inserted into the spindle can easily slip out of the spindle during spinning. It is tightly fitted to the spindle due to both a certain amount of pushing to prevent the thread from being pulled up, the tightening caused by the tension of the wound thread, and the biting phenomenon caused by the temperature difference, and it is easy to pull it up by hand. The reality is that it is difficult to extract the material from the spindle, and when automatic machines are used, errors occur when removing it from the spindle. The purpose of this application is to prevent such extraction errors by loosening the fitting between the full bobbin and the spindle prior to extraction, so that the full bobbin gripped by the gripper can be reliably extracted. . The present application is intended to be applied to the group lifting type of Japanese Patent Publication No. 1981-8136, which the applicant previously filed, but the application of the present application is not limited to this and is applicable to other types of automatic doffing as well. Needless to say, it is applicable. 1 is the doffing machine body and spinning machine 2
The process of doffing by traveling along the front of the doffing tube and replacing the empty tube is as detailed in Japanese Patent Publication No. 56-8136, but the mechanism operation for doffing etc. is not directly related to the present application. So all of that will be omitted.

による把持抜き取りにそなえる。The operating rod 14 is composed of a first bar 15, a second lever 16, a third lever 17, and a swing lever 18. The rod 13a of the cylinder 13 is connected to the first lever 15. Ru. The swing lever 18 has an intermediate portion pivotally supported by the doffing machine main body 1, a roller 20 provided at the upper end thereof is fitted so as to be in contact with the upper surface of the long groove 8 of the slide metal 4, and the lower end and the second
A third lever 17 is connected between the lever 16 and the four levers to form a link mechanism. Therefore, when the cylinder rod 13a is pulled up, these four levers 15,
16, 17, and 18 are interlocked, and the main rod 3 swings toward the front side of the spinning machine 2 (upper side in FIG. 1, right side in FIG. 2). When the winding of the yarn on the empty bobbin on the dust spindle 21 is finished and the bobbin 22 is full, the spinning machine 2 stops, and the doffing machine 1 carried by the carrier is docked on the stopped spinning machine 2, and the spinning machine 2 is docked on the spinning machine 2. The fork 10 is positioned at a position corresponding to the spindle 21 (corresponding to the ready-to-fill bobbin 22) and stopped, and as shown in FIG. Hold it and confront it. Next, when the cylinder 13 is actuated and the cylinder rod 13a is pulled up, the link constituted by the actuation rod 14 is actuated and is fitted into the long groove 8 of the slide metal 4 provided at the upper end of the swing lever 18. The roller 20 (while sliding in the long groove 8) swings the main rod 3 toward the right side in FIG. 2 toward the spinning machine 2. When the main rod 3 swings to the position shown in FIG. It enters between the lower end surface of the corresponding full bobbin 22 and the warp 23 of the spindle 21, and the long groove 8
The roller 20 that was in contact with the upper surface slides to the bottom and comes into contact with the lower surface. As described above, the fork 10 comes into contact with the bottom surface 11a of the mounting groove 11 and is prevented from rotating downward, thereby maintaining a substantially horizontal position, and moves in an arc shape due to the swinging of the main rod 3. The spindle 21 enters the spindle 21 in such a way that it rolls up, and as shown in the enlarged view in FIG. And at point B, the full bobbin 22 and the warp 23 are in point contact.As described above, the fork 10 enters the spindle 21 and the forward movement of the fork 10 is controlled by the wedge effect. cylinder 13 continues to operate, but fork 1
Since the main rod is also prevented from further swinging by 0, the roller 20 of the swing lever 18 is moved by the slide metal 4
Push the bottom surface of the long groove 8 of the slide metal 4 against the spring 7.
As a result, the fork 10 reverses upward using the contact point B with the warp 23 as a fulcrum, and uses the principle of a screw to forcefully push up the full bobbin 22 to bring it into tension with the spindle 21, as shown in FIG. The fitting is loosened to prepare for gripping and extraction using an appropriate gripping tool.

る事なく作動伝導が行なわれる。When the loosening operation and full bobbin extraction operation shown in FIG.
returns to the position shown in FIG. 2, the inverted fork 10 is held in its original state by falling under its own weight, and the slide metal 4 is also pushed by the spring 7 to return to its original state and waits for the next loosening operation. In the embodiment, the fork 10 is fully loaded with the bobbin 22.
Although the fork 10 is inserted diagonally between the fork 10 and the warp 23 and is brought into point contact with the spindle 23, this can also be done by inserting the fork 10 deeply and bringing the mounting rod 12 into direct contact with the spindle 21.
In this case, since a force perpendicular to the axial center of the spindle 21 is applied straight, there is a risk that the axial center of the spindle 21 will be misaligned if the work is repeated over a long period of time. Furthermore, although the operating rod 14 has been described as a link made by combining four bars, it is not limited to this, but it may be used as long as it transmits the operation of the cylinder 13 to the main rod 3 and gives the main rod 3 a predetermined swinging motion. This is sufficient and can be set arbitrarily depending on the mounting position of the cylinder 13. Since automatic machines such as doffing machine 1 run along the front of spinning machine 2 and run between the already installed spinning machines, the machine width is extremely limited, especially in the longitudinal direction. However, as mentioned above, the main parts of the cylinder 13 and the main rod 3 are housed in the doffing machine 1 in a substantially upright manner, and the operating range is limited to only a slight swing of the main rod 3. It can be easily installed within the width of the machine, and by using a link mechanism, it can be set appropriately to conduct operation transmission without interfering with other mechanisms.

構の構成を簡易化し得る利点がある。In addition, since the hydraulic cylinder 13 is used as the operating source, the fit between the spindle 21 and full bobbin 22 is abnormally tight, causing the fork 1
Even if the main rod 3 cannot be reversed or the swinging of the main rod 3 is inhibited for some reason, resulting in an overload exceeding the set pressure, oil leakage may occur, causing not only damage to the equipment itself but also damage to the spindle. There is absolutely no risk of harm to 21. As described above, in the present invention, when loosening a full bobbin that is tightly fitted to the spindle, the main rod is swung forward and the tip of the fork is placed between the lower end surface of the full bobbin and the warp of the spindle. After inserting the fork, the rear end of the fork is lowered and the fork is rotated upward using the point of contact with the warp as a fulcrum, so the action of the fork's screw powerfully pushes up the full bobbin and makes the full bobbin full. The bobbin can be loosened without forcing the spindle. Furthermore, after the above-mentioned loosening work is completed, the push-down of the rear end of the fork is released and the main rod is swung backwards to move the fork away from the spindle, thereby ensuring stable rotation of the spindle. It can also be carried out on a traveling doffing machine without any problems. In addition, the fork's back and forth movement and the lowering of the fork's rear end are performed by the back and forth rocking of the swing lever, so the fork movement can be made smooth and stable, and the structure of the drive mechanism can be simplified. There are advantages that can be realized.
