Description

[Detailed description of the invention] C. Industrial application field] The present invention moves along the longitudinal direction of the Sei 4413 machine,
A method for taking out the remaining thread bobbin of a sinter changing machine, in which the remaining thread bobbin after the roving has been used is exchanged with the spare sintered thread suspended from the spare sintered winding row of the creel by raising and lowering and moving back and forth the bobbin changing arm. Regarding.

(Prior Art) In a spinning frame, roving is pulled out from a shinomaki suspended from a creel at a high position and is supplied to a draft part below.

Since the VJ winding has a considerably larger diameter than the spindle gauge of a spinning machine, the Shinomaki is generally suspended from creel rails arranged in two rows, inside and outside. Then, when the supply of roving to the draft part progresses and the remaining yarn (support) of the Shinomaki becomes less, it is necessary to replace it with a new Shinomaki (fJ [replacement]). This work has long been carried out by a worker manually carrying out the shinomaki transported by a trolley, or by having the same worker replace the spare shinomaki that has been placed on a creel shelf in advance. . In addition, in addition to the two inner and outer creel rails, another rail is provided on the outside, and a spare JI volume is suspended from this rail, and an operator performs the replacement work as necessary. There is also.

However, the shinomaki is hung higher than the worker's height, and in recent years, the weight has increased to around 3 kilograms, and each spinning machine requires around 400 shinomaki, making it difficult to replace the shinomaki. is a hard labor for the workers.

As a method to solve this problem, Japanese Patent Laid-Open No. 58-8163
Publication No. 1 and Japanese Unexamined Patent Application Publication No. 60-71724@
A shin replacement filter is provided that automatically replaces a spare shin suspended from a shin winding rail and a remaining yarn bobbin that supplies roving to a draft bar and is almost empty. This Shinomaki machine takes out the remaining yarn boggon by lifting and lowering and moving back and forth a pair of interchangeable arms, and suspends it on the spare Shinomaki rail. Hang it on a creel.

[Problem that the invention seeks to solve]

In the above-mentioned Japanese Patent Application Laid-Open No. 58-81631, no special consideration is given to cutting the roving connected to the draft bar when taking out the remaining yarn bobbin from the creel.

On the other hand, in Japanese Patent Application Laid-Open No. 60-71724, a bobbin support mounted on an exchange arm is made rotatable, and the bobbin support is rotated with the remaining thread bobbin fitted onto the bobbin support, and It is designed to pull and cut the roving thread that passes through the thread kite and connects to the draft bar.

Therefore, in both of the above conventional techniques, the cutting position of the roving becomes unspecified, which not only makes it difficult to cut the thread, but also makes it difficult to cut the thread.
If the cutting position is too close to the draft bar, there will be no supply of roving, making it impossible to splice the yarn, resulting in yarn breakage. The above-mentioned inconvenience becomes especially noticeable when the yarn splicing work is automated regardless of the availability of yarns.

In order to solve the above problem (e), the applicant first moved the spinning machine along the longitudinal direction of the spinning machine frame and suspended it from the preliminary winding row of the creel by lifting and lowering the bobbin changing arm and moving it back and forth. In the sash changing machine that exchanges the spare jLJ and the remaining yarn bobbin after the roving has been used, the roving connected from the remaining yarn bobbin to the draft bar is placed in the bobbin exchanging arm at a predetermined position in the forward position of the exchanging arm. We have proposed a device for taking out the remaining yarn boggons of the Shino change machine, which is equipped with a cutting means.

In the above-mentioned proposed technique, by cutting the roving by the cutting means, the problem of variation in the cutting position of the roving can be solved. However, in order to prevent the spinning machine from stopping due to roving splicing after the roving change, when taking out the remaining yarn bobbin, the amount of roving required for roving splicing is pulled out from the remaining yarn bobbin in advance and the roving is cut. do. At this time, since the roving is pulled out from the remaining yarn bobbin at a speed faster than the spinning speed, the remaining yarn bobbin swings from side to side around the bobbin hanger.

If you try to insert the peg at the end of the replacement arm where the remaining thread bobbin is shaking, the peg will not fit into the recess at the bottom of the bobbin, and the peg will push the bobbin up.
This may cause the replacement operation to stop or cause damage to the bobbin.

[Purpose of the invention]

In view of the above-mentioned points, the present invention provides a spinning machine for a spinning machine.
An object of the present invention is to provide a method for taking out a remaining thread bobbin of a TI changing machine, which prevents the remaining thread bobbin from being pushed up by a peg at the tip of the replacing arm without shaking the remaining thread bobbin when taking out the remaining thread bobbin with a bobbin changing arm. do.

[Means for solving problems]

In the present invention, the above-mentioned purpose is achieved by raising and lowering the bobbin changing arm to remove the remaining yarn bobbin after the pre-mesh winding and roving yarn suspended from the preliminary winding row of the creel of the spinning frame frame are used. On the Shino N machine to be replaced, the end of the bobbin replacement arm is placed in the recess at the bottom of the remaining thread bobbin suspended from the bobbin hanger so that the remaining thread bobbin can rotate around the bobbin hanger when the roving is pulled out from the remaining thread bobbin. Raise the exchange arm until it loosely engages the tip of the formed peg, pull out the required amount of roving from the remaining thread bobbin when replacing the bobbin, then raise the bobbin exchange arm to the final end to remove the remaining thread bobbin. This is achieved by the method of removing the remaining thread from the bobbin of Shinogaishi.

(Function) In the present invention, the lifting of the exchange arm is stopped before the peg at the tip of the exchange arm is completely inserted into the remaining thread bobbin.This allows the tip of the peg to be inserted loosely into the remaining thread bobbin. The remaining thread bobbin remains suspended from the bobbin hanger.Therefore, when pulling out the roving from the remaining thread bobbin, the remaining thread bobbin can rotate around the bobbin hanger.
Furthermore, even if the remaining thread bobbin shakes at this time, the peg faces the recessed portion of the remaining thread bobbin, so the remaining thread bobbin will not come off the peg. After pulling out the required amount of roving from the remaining thread bobbin, the exchange arm is raised to the final end and the remaining thread bobbin is taken out. The drawn-out roving is cut by a cutting means after the required amount of roving is pulled out and before the remaining yarn bobbin is taken out. The roving splicing may be performed automatically or manually.
