In spinning machines, yarn twisting machines, etc., when automatically replacing a full bobbin using an auto-doffer device, in order to ensure automatic winding of thread onto the bobbin, there is a number of It is necessary to firmly fix the wrapped tail thread so that it does not move. If the tail thread moves due to a slight force at the tail thread winding section, when the ring rail rises to the bobbin thread winding start position, the end of the thread may become loose, causing the traveler's posture. It is easy to break the thread and cause thread breakage at the start of operation.

は、次の玉揚げ作業時まで切断されないため、玉
揚げを繰り返していくたびに尻糸の上にさらに新
しい尻糸を数回巻き付けていくことになる。 The biggest reason why it is difficult to firmly fix the tail thread to the tail thread at the spindle base is the presence of the tail thread wound around the tail thread. In other words, the tail thread at the tail end of the spindle base is wound around the knurling surface several times to prevent it from moving, but the crossover thread that connects the bobbin to the end thread is not cut until the next doffing operation. Therefore, each time the doffing is repeated, a new piece of string is wrapped around the string several times.

案した（特願昭62−130632号明細書）。 Therefore, in order to solve the problems of the prior art, to securely fix the tail thread to the spindle base, and to reliably dispose of the tail thread remaining during machine operation, the present inventor first fixed the tail thread to the spindle base. An upper slit ring is fixed to the upper slit ring, and a cylindrical body having a lower slit ring thereunder and whose lower part expands by centrifugal force is fitted so as to be slidable in the axial direction of the base of the spindle, and further the cylindrical body is expanded. The lower end of the opening can come into contact with a guide surface fixed to the spindle base, and the upper slit ring and the lower slit ring are pressed to form a tail thread holding part, and the lower part of the cylinder body is moved by the centrifugal force of the spindle. We proposed a tail thread processing device in which, when expanded, the cylindrical body slides downward in the axial direction of the spindle base, releasing the pressed state between the upper slit ring and the lower slit ring (Japanese Patent Application No. 130632/1988). No. Specification).

In the present invention, an upper slit ring is fixed to the spindle base, and a cylindrical body having a lower slit ring at the upper end and whose lower part expands due to centrifugal force is fitted under the upper slit ring so as to be slidable in the axial direction of the spindle base. The expanded lower end of the cylindrical body can be brought into contact with a guide surface fixed to the spindle base, and the upper slit ring and the lower slit ring are pressed to form a tail thread clamping part, and the spindle is centrifugally When the lower part of the cylindrical body is expanded by force, the cylindrical body slides downward in the axial direction of the spindle base, thereby releasing the pressed state between the upper slit ring and the lower slit ring, The lower part of the cylindrical body is divided by a plurality of slits, and a spring is provided for actively restoring the lower part of the cylindrical body from the expanded state to the original state when the spindle is stationary. This company provides tail yarn processing devices for spinning machines, yarn twisting machines, etc.

The tail thread processing device of the present invention not only uses the elasticity of the cylinder itself to restore the lower part of the cylinder from the expanded state to its original state when the spindle is stationary.
Because it also utilizes the force of a separate spring,
The lower part of the barrel body is actively restored to its original state, and as a result, the tail thread (crossing thread)
is securely and firmly fixed.

固定効果も一段と向上させることができる。 Furthermore, by carving outward radial grooves on the upper surface of the lower slit ring, the remaining yarn from the tail thread is caught in the tail thread pinching part of the spindle where the main tail thread processing device is newly installed. If the remaining thread is not released from the end, for example, by inserting a hook-shaped jig or the like from the outside into this radial groove to catch and remove the remaining thread, the remaining thread can be easily removed and the thread can be removed. When winding the thread around the bobbin, the tail thread at the beginning of winding of the thread is wedged into the upper part of the edge of the radial groove, thereby further improving the effect of fixing the tail thread to the tail thread holding part.
以下、図面により本考案の装置を説明する。 Hereinafter, the apparatus of the present invention will be explained with reference to the drawings.

次に、第４〜８図により、第１図に示した装置
を用いた場合の本考案装置の作用について説明す
る。 Next, the operation of the device of the present invention when the device shown in FIG. 1 is used will be explained with reference to FIGS. 4 to 8.
なお、第１図と同一部分については、第１図と
同じ番号を付し、その説明を省略する。 Note that the same parts as in FIG. 1 are given the same numbers as in FIG. 1, and the explanation thereof will be omitted.

されている。 First, FIG. 4 shows the state immediately before starting winding onto the bobbin 1 in a spinning machine, a yarn twisting machine, etc. The cylinder body 8 is pushed upward and the upper slit ring 5
The lower slit ring 6 is pressed to form a tail thread holding portion 11. The yarn Y from a roller section (not shown) of a spinning machine, a twisting machine, etc. passes through a traveler 15 fitted to a ring 14, and its end touches the tail yarn clamping section 11 within about half to one turn. It is wrapped around and held in place.

転速度を所定の回転速度にまで上昇させていく
と、筒体８の下部７が遠心力によつて拡開し、下
端９が固定ガイド面１０に当接するようになる。 Next, when winding is started, the ring 14 rises to the winding position of the bobbin 1 as shown in FIG. A crossover thread 12 is formed between the bobbin 1 and the bobbin 1. The ring rail 15 and the ring 4 reciprocate within the end thread winding position range of the bobbin 1,
When the winding of the yarn Y is started on the bobbin 1 as shown in the figure, and then the rotational speed of the spindle 2 is increased to a predetermined rotational speed as shown in FIG. It expands due to the force, and the lower end 9 comes into contact with the fixed guide surface 10.

糸１２′となる。 Then, the movement of the lower end 9 is restrained by the fixed guide surface 10, so when further centrifugal force is applied, the cylinder 8 is automatically pulled down (in the direction of arrow A) and the tail thread is pulled down. The crossover thread 12 held by the holding part 11 is released and removed from the tail thread holding part 11 by the centrifugal force of rotation of the spindle 2, and becomes a tail thread 12'.
この際、固定ガイドの上端と下部スリツトリン
グ６の下面とが密着し、かつカバー１８によつて
覆われるため、固定ガイド内へ風綿などが入り込
むようなことがない。 At this time, since the upper end of the fixed guide and the lower surface of the lower slit ring 6 are in close contact with each other and covered by the cover 18, there is no possibility that fluff or the like will enter into the fixed guide.
ボビン１上に糸条Ｙが満管になつたら、リング

の状態に戻り、先端９が下部固定ガイド面１０′
に当接して筒体８を上方へ押し上げ、尻糸挟持部
１１が押圧状態に戻つているため、この巻き終え
た糸条Ｙの端部の挟持が極めて確実に行われる。 When the yarn Y is fully loaded on the bobbin 1, the ring rail 15 and the ring 14 are quickly lowered to the position of the tail yarn clamping part 11 again as shown in FIG.
The thread at the end of winding is held by the tail thread holding part 11 within one rotation, and the spindle is stopped. In this case, the previous tail string 12' has been completely released and removed from the tail string holding part 11, and as the rotational speed of the spindle 2 decreases, the force of the spring 16 actively moves the lower part of the cylinder body 8. 7 returns to its original state from the expanded state, and the tip 9 reaches the lower fixed guide surface 10'.
Since the cylindrical body 8 is pushed upward by contacting with the cylindrical member 8, and the tail thread clamping portion 11 returns to the pressed state, the end portion of the finished thread Y can be clamped extremely reliably.
次いで、スピンドルの回転が停止したのち、満
管ボビンをオートドツフアーで引き上げる。 Next, after the rotation of the spindle has stopped, the full bobbin is pulled up by an automatic transfer.
その際、リング１４を尻糸挟持部１１の位置へ

Or, when the spindle base of a conventional spinning machine, a yarn twisting machine, etc. is changed to a main yarn processing device, the yarn holding portion 11 is cut off during adjustment before production operation.
Gradually reduce the number of times the tail thread is wound around the tail thread holding part 11 to 1 turn or less so that the remaining thread (not shown) of the previous tail thread 12' remaining on the tail thread 12' is automatically released. If the remaining tail thread is not released from the tail thread holding part 11 at the adjustment stage, a hook-shaped jig (not shown) with a hook-shaped tip (not shown) is slid along the radial groove 19. The remaining threads can be removed by removing the threads. In addition, since the end of the yarn Y is wedged into the edge upper part 19' of the radial groove 19 when it is wound around the tail thread clamping part 11, the effect of fixing the tail thread to the tail thread clamping part 11 is further improved.
