Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention moves along the longitudinal direction of a spinning machine base and is hung on a spare shino reel of a creel by raising and lowering and moving back and forth of a bobbin exchange arm. The present invention relates to a method for taking out a residual thread bobbin of a Shino transfer machine for exchanging a spare shinomaki and a residual thread bobbin after roving has been used.

[Conventional technology]

In the spinning machine, the roving is drawn from the Shino-maki suspended on the creel at a high position and supplied to the draft part below.

Since the Shino-maki has a diameter considerably larger than that of the spindle gauge of the spinning machine, the Shino-maki is generally suspended on the creel rails arranged in two rows inside and outside. Then, when the supply of roving to the draft part progresses and the amount of remaining yarn in Shino-maki becomes small, it is necessary to replace it with a new Shino-maki.
This work has been performed for a long time by an operator manually performing Shino-maki carried by a dolly, or by replacing the spare Shino-maki preliminarily placed on a creel shelf. Further, in addition to the inner and outer two rows of creel rails, one rail is further provided on the outer side of the creel rail, and a spare shinomaki is hung on the rail, and an operator performs the replacement work as needed. There is also.

However, Shino rolls are suspended above the worker's height, and in recent years their weight has been around 3 kilograms, and around 400 spinning machines are needed, so Shino roll replacement work is required. Is hard work for workers.

As a method for solving this problem, Japanese Unexamined Patent Publication No. 58-81631 and Japanese Unexamined Patent Publication No. 60-71724 provide a spare shinomaki suspended on a spare shinomaki rail and a roving yarn to a draft part. There is provided a Shino-changing machine that automatically replaces the remaining thread bobbin that is almost empty. This Shino-changing machine takes out the residual thread bobbin by lifting and lowering the pair of replacement arms and suspends it on a spare Shino-maki rail. Instead, the spare Shino-maki suspended on the spare Shino-maki rail is used as a creel. Let it hang.

[Problems to be solved by the invention]

In Japanese Patent Laid-Open No. 58-81631, no special consideration is given to cutting the roving thread connected to the draft part when the residual thread bobbin is taken out from the creel.

On the other hand, in Japanese Patent Laid-Open No. 60-71724, a bobbin support mounted on an exchange arm is made rotatable, and a bobbin support is rotated with a residual thread bobbin fitted on the bobbin support. The roving thread connected to the draft part through the thread guide is pulled and cut.

Therefore, in both the above-mentioned conventional techniques, not only the cutting position of the roving becomes unspecified and it becomes difficult to perform the yarn splicing work,
If the cutting position is too close to the draft part, there is a disadvantage that the roving yarn to be supplied runs out and the yarn joining operation cannot be performed, resulting in yarn breakage. And, when the yarn splicing work is automated without manual labor, the above inconvenience becomes remarkable.

In order to solve the above-mentioned problem, the present applicant first moved along the longitudinal direction of the spinning machine base and was suspended in the preliminary reel winding of the creel by raising and lowering and moving the bobbin exchange arm back and forth. In a Shino transfer machine for exchanging a spare Shino winding and a residual thread bobbin after the roving has been used, a roving thread continuing from the residual thread bobbin to a draft part is moved to a predetermined position on the bobbin exchange arm at a forward position of the exchange arm. We have proposed a residual thread bobbin take-out device for Shinoshinki machines equipped with cutting means for cutting.

In the above-mentioned proposed technique, the problem that the cutting position of the roving varies due to the cutting of the roving by the cutting means is solved. However, after changing the roving yarn, in order to prevent the spinning machine from being stopped by performing roving splicing, when removing the residual yarn bobbin, pull out the necessary amount of roving yarn for roving yarn splicing from the residual yarn bobbin in advance and cut the roving yarn. To do. At this time, since the roving yarn is pulled out from the residual yarn bobbin at a speed faster than the spinning speed, the residual yarn bobbin sways left and right around the bobbin hanger. If you try to insert the peg at the tip of the replacement arm into a place where the residual thread bobbin is swinging, the peg will not fit into the recess at the bottom of the bobbin, and the peg will push the bobbin up, thus stopping the replacement operation. Or damage the bobbin.

[Object of the Invention]

In view of the above points, the present invention provides a spinning machine for spinning machines,
An object of the present invention is to provide a method for removing a residual thread bobbin of a Shino-changing machine, which prevents the residual thread bobbin from being pushed up by a peg at the tip of the replacement arm when the residual thread bobbin is taken out by the bobbin exchange arm. To do.

[Means for solving problems]

In the present invention, for the above-mentioned purpose, the bobbin exchanging arm is moved up and down to exchange the spare shinomaki suspended in the spare shinomaki row of the creel of the spinning machine stand and the residual thread bobbin after the roving is used. In the Shino-changing machine, when the roving is pulled out from the residual thread bobbin, the residual thread bobbin is hung on the bobbin hanger so that the bobbin hanger can be rotated around the bobbin hanger. Raise the exchange arm until the tip of the peg is loosely engaged, pull out the required amount of coarse thread from the residual thread bobbin when exchanging the bobbin, and then raise the bobbin exchange arm to the final end to remove the residual thread bobbin. This is achieved by the method for taking out the residual thread bobbin of the Shino-changing machine.

[Action]

In the present invention, the raising of the exchange arm is stopped before the peg at the tip of the exchange arm is completely inserted into the residual thread bobbin. As a result, the tip of the peg is loosely inserted into the residual thread bobbin, and the residual thread bobbin remains suspended on the bobbin hanger. Therefore, when pulling out the roving from the residual thread bobbin, the residual thread bobbin can rotate around the bobbin hanger, and even if the residual thread bobbin sways at this time, the peg faces the concave portion of the residual thread bobbin. The residual thread bobbin never comes off the peg. After pulling out the required amount of roving from the residual thread bobbin, raise the exchange arm to the final end and take out the residual thread bobbin. The pull-out roving yarn is cut by the cutting means after the required amount of roving yarn is pulled out and before the residual yarn bobbin is taken out. The roving splicing may be performed automatically or manually.
