Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a sliver drill for guiding a sliver to the spinning machine body of a semi-worsted spinning machine.

(b) Prior art As shown in Fig. 3, a conventional sliver drill consists of a back drill 1' and a front drill 2', both of which are long and have a length corresponding to the number of spindles of a spinning machine. It is installed in

(c) Problems to be Solved by the Invention In such conventional sliver drills, it is impossible to set the sliver from the rear can on the crill until the sliver has been sent out from the can at the front end of the bicoiler. Because of this, it takes a long time to switch between the front and rear slivers.
I was inefficient. The present invention aims to improve this point.

(d) Means for Solving the Problems Explained with reference to illustrative drawings, the present invention is directed to a sliver drill which is composed of a back drill 1 and a long front drill 2 and which guides a sliver 4 to a spinning machine main body 3. , consisting of a large number of short crills 1a, 1b, 1c... in which back crills 1 are arranged in parallel,
A distance 5 necessary for removing the sliver 4 is provided between each short creel, and each short creel 1a is attached to each arm 7a, 7b, 7c... branched from a long shaft 6 rotatably provided above the short creel. ,1
This invention relates to a sliver creel for a semi-worsted spinning machine, characterized in that each of the short creels can be rotated at once like a pendulum by connecting b, 1c, . . . The appropriate length of each short krill is for two or four spindles.

(e) Effect The effect of the present invention will be explained using FIGS. 4 to 7. FIG. 4 shows a state in which the sliver 4a of the front can 9a is supplied to the spinning machine main body 3 through the back creel 1 and the front creel 2, and spinning is being carried out. In the present invention, since the back drill 1 is made up of a large number of short drills arranged in parallel at intervals 5 necessary for removing the sliver 4, while the sliver 4a at the front end is being supplied, the back drill 1 is The sliver 4a is removed from the creel 1 after passing through the gap 5, and the front opening can 9a is moved between the back creel 1 and the front creel 2, as shown in FIG. It is made to be directly supplied to the front creel 2. Next, as shown in FIG. 6, a rear can 9b is prepared in front of the back drill 1, and the end of the sliver 4b is set in the back drill 1. As soon as the sliver 4a of the front can 9a disappears, as shown in FIG.
The shaft 6 is rotated and the arm 7 is rotated in the direction of the arrow so that the back drill 1 is positioned above the front drill 2. In this state, perform the thread splicing work. When the thread is connected, back creel 1
is rotated in the opposite direction to the arrow to return to its original position, and spinning of the sliver at the back end is started in the state shown in FIG. In the above, since each short back drill 1 is connected to the shaft 6 via each arm 7, the back drill 1
It is possible to rotate all of the objects at once like a pendulum.

(f) Effects of the invention Since semi-worsted wool is produced in small batches with a wide variety of products, it has become common practice to change the sliver for each spinning machine once or twice a day. In a conventional semi-worsted spinning machine equipped with a sliver creel, when changing over, it takes about 30 minutes to remove the can at the front opening, about 30 minutes to line up the cans at the rear opening, and hang sliver 4' on back crill 1'. Normally, it takes about 30 minutes to pass the sliver from the back creel 1' to the front creel 2', and it takes a lot of time to change the sliver.
Using the sliver drill of the present invention, changeover time is only a few minutes, and changeover efficiency is greatly improved because the rear end is fully prepared by the time the front end is completed.

Claims (1)

[Claims] 1. In a sliver crill that is composed of a back crill and a long front crill and guides the sliver to the main body of the spinning machine, the back crill is composed of a large number of short criles arranged in parallel, and the intervals necessary for removing the sliver are provided between each short crill, By connecting each short krill to each arm branched from a long shaft rotatably provided above the short krill, each short krill can be rotated at once like a pendulum. The feature is the sliver creel of the semi-worsted spinning machine.
