Abstract

(57) [Summary] [Objective] To provide a cleaning device for automatically removing single fibers attached to a draft roller. A cleaning belt, which is an endless belt supported so as to be pressed by a draft roller, is provided with cleaning belt driving means for intermittently moving the cleaning belt in a predetermined direction.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for cleaning a draft roller in a draft device of a spinning machine. In this specification, the draft roller is referred to as including the apron in the draft device.

[0002]

[Prior Art]

 The draft roller of the drafting device rotates by firmly holding the sliver for pulling or holding, and in the roller without an apron, fine grooves are formed on the surface, so that the single fiber is Easy to attach and accumulate. Since the function of the draft roller deteriorates when the amount of the adhered fibers accumulated increases, it may cause yarn breakage and deterioration of the physical properties of the yarn, so the draft roller had to be inspected and cleaned from time to time.

[0003]

[Problems to be solved by the device]

 Therefore, an object of the present invention is to provide a cleaning device that automatically removes the single fibers adhering to the draft roller, and to eliminate or simplify the inspection and cleaning work.

[0004]

[Means for Solving the Problems]

 A cleaning belt, which is an endless belt supported so as to be pressed by a draft roller, is provided with a cleaning belt driving means for intermittently moving the cleaning belt in a fixed direction.

[0005]

[Action]

 In the cleaning device of the present invention, the longitudinal direction of the cleaning belt is aligned with the arrangement direction of the draft rollers so that the cleaning belt can be removed or moved above and below the draft device or above or below the draft device as needed. To install. In the installed state, the cleaning belt is lightly pressed by the draft roller, so that the peripheral surface of the draft roller in operation makes contact with and slides on the cleaning belt. It is desirable to contact the cleaning belt with all draft rollers, but the front roller, which does not adhere much fiber, may be removed from the processing target.

The fibers attached to the surface of the draft roller (including the apron belt; the same applies below) are peeled off by the cleaning belt by coming into contact with the cleaning belt and sliding. Since the peeled fibers accumulate on the cleaning belt, the cleaning belt driving means intermittently drives the cleaning belt to move the contact position. The fibers accumulated on the cleaning belt are appropriately removed by a method such as suction or scraping.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In the illustrated embodiment, the top roller except the front roller 5 of the 5-wire draft device in which the aprons 3 and 4 are mounted on the second roller 1 and the force roller 2 (in the roller on which the apron is mounted, The apron) was installed so as to be cleaned, and is installed above the draft device. When cleaning the bottom roller of the draft part, a bottom roller cleaning device may be provided below the bottom roller and in contact with the peripheral surface of the bottom roller.

The cleaning device 6 for cleaning the top roller will be described below. The cleaning belt 8 is stretched between rollers 9 and 10, and both rollers 9 and 10 are freely rotatable. The roller 9 has a ratchet wheel 11 fixed thereto. On the other hand, as a rotating means of the ratchet wheel 11, a rod 14 is attached to a rotating shaft 13 via an eccentric wheel 12, and a claw 15 at the tip of the rod 14 that reciprocates as the rotating shaft 13 rotates is used. Interlocks with the ratchet wheel 11 and rotates intermittently.

The frame 16 supporting the rollers 9 and 10 is arranged so as to cover the entire draft device (hereinafter, referred to as a set state) as shown in the figure in the operating state of the device, but enables the inspection of the draft device. Therefore, it is possible to turn upward with the end portion on the sliver introduction portion side (the right end in FIG. 1) as the fulcrum.

The frame 16 has a pressing member 19 for pressing down the cleaning belt 8 so as to surely contact all of the aprons 3 and 4, the third roller 17, and the back roller 18 when the frame 16 is in the set state. Are installed in three places. In addition, a cotton wool suction pipe 21 having an opening 20 is attached to the tip at a position close to the roller 10 and a position close to the front roller 5, and the base thereof is a flexible hose 22 and a main duct (Fig. Connected (not shown). As the belt 8, a belt made of natural rubber or the like is used, and a belt that is easily charged is preferable.

Next, the operation of the cleaning device 6 during the operation of the draft device will be described.

When the rotating shaft 13 is rotated, the rod 14 attached via the eccentric wheel 12 reciprocates, and the pawl 15 at the tip catches the ratchet wheel 11 in the return cycle, and the roller that is integral with the ratchet wheel 11. 9 is rotated clockwise in the figure. By repeating this, the cleaning belt 8 is intermittently driven clockwise in the drawing. Whether the cleaning belt 8 is stationary or moving, the adhering fibers on the draft roller sliding on the cleaning belt 8 are scraped off and move to the surface of the cleaning belt 8.

Due to the intermittent movement of the cleaning belt 8, the fibers peeled off gradually move toward the front roller 5 while adhering to the cleaning belt 8, and finally when approaching the cotton wool suction pipe opening 20. From there, it is sucked into the fly dust suction pipe 21 and sent to the fly dust collecting device via the hose 22. Further, the fly dust adhering to the peripheral surface of the front roller 5 is directly sucked and collected by the blow dust suction pipe 21. A comb 21 that contacts the cleaning belt 8 and a cotton wool suction pipe 22 that opens in the vicinity of the comb 21 are added to the rear end position of the cleaning belt 8 to more reliably collect the fibers attached to the cleaning belt 8. You may do it. Further, although the above-mentioned embodiment is the cam drive system, it may be a belt drive system in which power is transmitted from the drive shaft to the roller of the cleaning belt via the power transmission belt.

[0015]

[Effect of the device]

 As described above, the present invention provides a cleaning belt, which is an endless belt supported by a draft roller so as to be able to press the cleaning belt, and the cleaning belt is provided at a contact surface with the draft roller in a direction opposite to the moving direction of the peripheral surface of the draft roller. Since the fibers adhering to the draft roller are constantly peeled off by moving the draft roller to the surface, the surface of the draft roller is always kept clean, stable drafting is possible, and the frequency of thread breakage is reduced. Quality improvement is also achieved.
