Description

[Detailed Description of the Invention] Technical Field The present application relates to a spare tape storage device for a spinning machine, a yarn twisting machine, etc. (hereinafter referred to as a spinning machine) using a pulley driving method.

Prior art and its problems In a pulley driving type spinning machine in which a large number of tapes wound around a chin pulley or chin roller each rotate a total of four spindles, two on the R and L sides of the spinning machine, the tape is cut. When or S
In preparation for changing the twisting direction from twisting to Z-twisting or vice versa, it is recommended to have a spare tape between each bearing that supports the drive shaft, and to store this spare tape in an appropriate storage container. This has been practiced for a long time and was disclosed in Japanese Patent Publication No. 52-27736 and put into practical use. However, in the conventional device described above, all of the containers for storing spare tapes are attached to the drive shaft, which not only causes a loss of drive power but also risks disrupting the rotational balance.
Furthermore, the endless tape surrounding the drive shaft generates heat and deteriorates due to friction caused by the rotation of the drive shaft, which is undesirable.

Purpose and Overview In view of the above drawbacks of the conventional device, in the present application, a spare tape is attached to the bearing of the drive shaft, which is a non-rotating part, so as to partially surround the bearing, and the remaining part is stored in a stocker. By attaching the stocker to the frame in a detachable manner, the drawbacks of the conventional device are eliminated.

Embodiments Next, the present application will be explained in detail with reference to drawings showing embodiments. Prior to that, the necessity of the preliminary tape will be explained with reference to FIG. 2 to aid understanding of the present application.

Figure 2 shows the case where the spindle is driven by the chin roller 1, but even in the case of a chin pulley, the chin pulley is attached to the tape winding position in Figure 1, and the following explanation is all about the chin pulley, chin pulley, and chin pulley. This is common to both rollers. Figure 2 shows only one part of the chin roller 1 supported by the bearing 2. It is fixedly supported by a shaft 3, and a plurality of chin rollers 1 are arranged in series as shown in FIG. 2 to constitute a long spindle drive system. A large number of tapes 4 are attached to each of the chin rollers 1 supported between the respective bearings 2.
It is well known that a single tape 4 is used to rotate a total of four spindles, two each on the R and L sides. Now, as shown in Figure 2, the P of chin roller 1 is
S-twisting is performed by winding tape 4 at the positions shown in P1, P3, and P5, respectively. To change this to Z-twisting, the tape 4 at position P1 is wound to P2, and then to P3.
The winding position must be changed from P4 to P5 to P6. However, as is clear from the drawing, the tape 4 wrapped around P1 and P5 can be replaced without any problem, but the tape 4 wrapped around P3 is obstructed by the bearing 2 and must be disassembled. It is not possible to replace P4. Therefore, by preparing a spare tape 5 for each section of each chin roller 1 supported by the bearing 2, the twist direction of S-Z and Z-S can be changed without disassembling the bearing 2 part. Needless to say, even if the tape should break, you can take immediate action. The present application relates to a storage device for the above-mentioned spare tape 5, as will be described in detail below.

Reference numeral 6 denotes a stocker, which is dish-shaped without a bottom plate, and has an insertion groove 7 for a spare tape 5 in its peripheral wall, and a U-shaped bullet piece 8 made of a leaf spring on its top surface 6a.
is attached using studs 9 or other appropriate means.
Inside the stocker 6 is a wind-up drum 13 having a retaining groove 10 for the spare tape 5 on the peripheral wall and a wind-up button 12 or a crank on the top surface 11 that protrudes outside the stocker 6. By turning the winding drum 13, the winding drum 13 can be freely rotated. It is preferable to interpose a spring washer or other appropriate elastic body 14 between the stocker 6 and the winding button 12 to prevent the winding drum 13 from spinning idly.

In the above manner, storage of the spare tape 5 in the present application is carried out as follows. First, the chin roller 1 on the right side in FIG. 2 is removed, and a spare tape 5 is attached to the outer circumference of the bearing 2, which is a non-rotating part, so as to partially surround the bearing 2, and the end 5a of the spare tape 5 is folded in two. is inserted into the insertion groove 7 and put into the stocker 6, and then the terminal 5a is further latched to the latching groove 10 of the winding drum 6, and the winding button 12 is turned to rotate the winding drum 13. After the remaining portion of the spare tape 5 is stored in the stocker 6, it is removably fitted into an appropriate position on the frame 15 using the bullet piece 8 attached to the stocker 6.
The attachment of the stocker 6 is not limited to the above-mentioned bullet piece 8, but the purpose can be achieved as long as it is easy to attach and detach and does not fall off from the frame 15 unless necessary.

Effects As described above, the present invention eliminates the drawbacks of the conventional device by attaching the spare tape to the outer periphery of the shaft bearing, which is a non-rotating part, and attaching the stocker containing the remaining part to the frame in a detachable manner. In addition, it is easy to store and take out spare tapes in the stocker, which is a great idea that contributes to improving work efficiency.
