Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a spinning machine in which the sliding contact of the suction cleaning device can be easily and safely replaced.

Generally, when forming a spun yarn from a sliver of synthetic fiber or natural fiber, a plurality of bottom rollers 41 are rotatably mounted on a machine frame 50 as shown in FIGS. a top roller 42 rotatably mounted on both sides of the other end of a top arm 43 rotatably mounted on the frame;
A draft device 40 comprising a sliver guide 44 disposed between each bottom roller drafts the sliver, and a yarn forming device 45 forms a spun yarn. During the above-mentioned drafting process, fibers, cotton dust, etc. adhere to each bottom roller, and if the amount increases, draft spots may occur, and the fibers, cotton dust, etc. adhered to the rollers may become lumps of cotton sludge on the drafted sliver. To prevent the thread from getting caught and causing breakage or thread defects, the sliding contact 46 is located below the bottom roller 41 and is attached to the machine frame 50 so that it is always in sliding contact with the roller surface.
The roller is attached to the roller with a bolt 47, and fibers, cotton dust, etc. adhering to the roller are peeled off, sucked with a suction nozzle 48, and discharged outside the machine.

However, if the sliding contact 46 is damaged, the operator inserts his/her hand deep into the rotating bottom roller 41 from below and loosens the bolt 47.
The sliding contact 46 is removed from the 0 and taken out of the machine, or the operation of the machine is stopped and work is carried out. Also, when installing a new sliding contact 46, the sliding contact 46 is inserted from below the roller to a predetermined position and attached to the machine frame 50 in the same manner as described above. This makes the work extremely difficult. Furthermore, in order to safely replace the sliding contact, it is necessary to stop the rotation of the rollers, resulting in problems such as a reduction in operating efficiency.

The present invention was developed as a result of studies aimed at solving the above-mentioned problems and providing a spinning machine in which the sliver guide and sliding connector can be replaced easily and safely. .

(Means for Solving the Problems) That is, the present invention includes a draft device in which a sliver guide is arranged between each draft roller, and a device that slides in contact with the draft rollers and peels off fibers and cotton dust adhering to the rollers. In a spinning machine having a suction cleaning device consisting of a sliding joint and a suction nozzle installed below the roller and sucking peeled fibers and cotton dust, the sliver guide and the sliding joint are attached to a common support rod. The purpose is to provide a spinning machine with

(Example) The spinning machine of the present invention will be explained.

1 is a draft device, and 2 is a yarn forming device. 3 is a back bottom roller, and 4 is a back bottom roller. 5 is a third bottom roller, and 6 is a third top roller. 7 is a second photo roller, to which an apron belt 12 is attached. 8 is a second top roller, to which an apron belt 13 is attached. 9 is a front bottom roller, and 10 is a front top roller. Each bottom roller is formed as a single shaft having a plurality of weights, and is rotatably mounted on the machine frame 30. The roller is adapted to rotate at a preset speed by a drive device (not shown). Each top roller is rotatably mounted on both sides of the top arm 13, one end of which is rotatably mounted on the machine frame 30, and the other end of the top arm 13.

A support rod 14 is inserted into a groove formed in the machine frame 30. A sliver guide 16 and a sliding contact 17 are attached to the support rod 14, as shown in FIGS. 2 and 3. The sliver guide 16 and the sliding joint 17 are either fitted so as to have a spring effect and sandwich the support rod 14 from both sides, or are fixed to the support rod 14 with bolts. In addition, the sliding joint can be in the shape of a loop or a flat plate as shown in the figure, and can be made of wear-resistant materials such as soft synthetic resin, synthetic rubber, felt, and cloth, but it is also possible to use a used Eprun belt. It is economical to manufacture it.

18 is a suction duct, and suction nozzles 19, 2
0 and 21 are connected via pipes 22, 23, and 24, respectively.

If the sliding joint is damaged during operation, rotate the top arm 13 of the corresponding weight draft device 1 upward to separate the top roller from the bottom roller, lift the support rod 14, and remove the top roller from the groove 30 of the machine frame 30.
Remove it from a and replace it with a new sliding contact. After replacing the damaged parts, insert the support rod 14 into the groove 3 of the machine frame 30.
0a to complete the replacement work.

(Effects of the invention) As mentioned above, the invention has the following advantages: by attaching the sliver guide and the sliding contact to a common support rod,
The sliding contact replacement work can be carried out safely and easily without stopping the rotation of the rollers.
