Description

[Detailed explanation of the invention] Purpose of the invention [Industrial field of application] This invention relates to a fluff removal device for removing fluff adsorbed to the suction ports of blowers installed near various spinning machines. be.

[Problems to be solved by the prior art and the invention]

Generally, in a spinning factory, air supplied from a blower is ejected through a nozzle to blow away the fluff generated from various spinning machines such as roving frames so that it does not stay in the thread path of the running yarn. It's summery. However, since this type of blower is installed under the machine base of the spinning machine, it tends to suck in large amounts of fluff flying around in the air and cause malfunctions.
Therefore, conventionally, for example, as shown in FIG. 1, a metal steel 3 is attached to the outer surface of the suction port 2 of the blower 1, and the air fluff C is adsorbed to the metal steel 3 by the suction action of the fan 4. 1. We have been trying to prevent wind cotton C from entering inside. However, according to such a conventional configuration, the fluff C accumulates on the metal steel 3 within a short time and reduces the intake efficiency of the blower 1.
The operator has to regularly remove the fluff C, which poses a problem in that maintenance work on the blower becomes troublesome.

Therefore, the purpose of this invention is to provide a new blower suction port that can automatically and continuously remove fly fluff adsorbed to the blower suction port, thereby facilitating maintenance work on the blower. An object of the present invention is to provide a fluff removal device.

Structure of the invention [Means for solving the problem] The present invention includes a drum that is rotatably supported in communication with the suction port of the blower and has a large number of ventilation holes formed on its circumference. , consisting of a drive mechanism for rotationally driving this drum, and a clearer that is supported so as to be movable in a direction away from the axis of the drum and is driven to rotate while in contact with the circumferential surface of the drum. A structure is adopted in which fluff adsorbed to the circumferential surface of the drum by the suction action is wound around the clearer as the drum rotates.

[Effect]

When the blower performs an intake action, the drum, which has a large number of ventilation holes formed on its circumferential surface, is rotated by a drive mechanism and is supported on its circumferential surface so as to be movable in a direction away from the axis of the drum. The cleared clearer is also driven to rotate while in contact with the circumferential surface of the drum. Therefore, even if fluff is attracted to the peripheral surface of the drum by the suction action of the blower, the fluff is automatically and continuously wound around the clearer by the driven rotation of the clearer.

Embodiment An embodiment of this invention in a blower for blowing off fluff installed under the stand of a roving frame in a spinning factory will be described below with reference to FIGS. 2 to 4.

As shown in FIGS. 2 and 3, a fan box 13 is attached to the blower 11 installed on the board 10 so as to surround the fan 12, and a suction port 14 is provided on the front surface of the fan box 13. It is opened. A shaft 17 is disposed between a support frame 15 fixed inside the suction port 14 and a support bracket 16 erected on the substrate 10 so as to face the suction port 14 with a gap therebetween. fixed,
A drum 19 is attached to this shaft 17 at a central boss portion 18.
is rotatably supported.

A ratchet wheel 20 is attached to one side of the outer peripheral edge of the drum 19, and a large number of small holes 21 for ventilation are provided throughout the circumferential surface of the drum 19. Further, an opening 22 is formed on the side surface of the drum 19 facing the suction port 14.
2 and the suction port 14 are communicated with each other in an airtight manner by an annular rubber seal member 23 fixed around the outer surface of the suction port 14. When the blower 11 is in operation, air is sucked into the fan box 13 through the small holes 21 of the drum 19 as the fan 12 rotates. Therefore, the fluff flying around in the air is attracted to the outer peripheral surface of the drum 19.

As shown in FIG. 2, a lever 25 is swingably supported at its base end by a bolt 24 at the outer end of the shaft 17, and at its tip is a plunger for a solenoid 26 attached to a part of the blower 11. 26a
is connected to. A ratchet pawl 27 that engages with the ratchet wheel 20 of the drum 19 is rotatably supported on the lever 25. When the solenoid 26 is energized, the lever 25 is swung as the plunger 26a moves in and out, and the ratchet pawl 27
The engagement of the drum 19 with the ratchet wheel 20 causes the drum 19 to rotate counterclockwise in FIG.

On the other hand, between the upper end of the support bracket 16 and a support plate 28 erected on the upper surface of the fan box 13 facing the support bracket 16, a conical cone whose circumferential surface is in contact with the drum 19 is provided. A table-shaped clearer 29 is supported in an inclined state with respect to the axis of the shaft 17. A pair of shaft portions 30 protruding from both end surfaces of the clearer 29 are connected to guide grooves 16a, 28a extending vertically, which are cut out in the support bracket 16 and the support plate 28, respectively.
This allows the clearer 29 to rotate and move up and down.

As shown in FIG. 4, the clearer 29 includes an iron core 32 formed integrally with the shaft portion 30, a wooden frame 33 provided on the outer surface of the iron core 32, and a wooden frame 33 wound around the outer surface of the wooden frame 33. The felt 34 is normally pressed against the circumferential surface of the drum 19 by the weight of the iron core 32 and the like. When the drum 19 is rotated as the solenoid 26 is driven, the clearer 29 is driven to rotate, and the fluff C adsorbed on the circumferential surface of the drum 19 is wound onto the outer surface of the felt 34.
With the increase in the amount of winding, clearer 29
is the drum 1 along both the guide grooves 16a, 28a.
9 in a direction away from the axis.

Now, according to the fluff removal device of this embodiment configured as described above, the fluff C flying around in the air is adsorbed to the circumferential surface of the drum 19 by the suction action of the fan 12, and the fluff C is absorbed into the fan box 13. Since clean air from which the fluff C has been removed is introduced, there is no fear that the blower 11 will malfunction due to clogging of fluff inside the machine, unlike in the past. As the drum 19 rotates, the fly fluff C adsorbed on the drum 19 is sequentially wound up on the clearer 29, thereby avoiding clogging of each small hole 21 and moving the blower 1
1 can be maintained in a good state.

Moreover, if the clearer 29 is formed into a conical shape as in this embodiment and rotates at an angle with respect to the axis of the shaft 17, the difference in circumferential speed between the large diameter side and the small diameter side causes the drum 19 to Since slips occur between the drum 19 and the clearer 29, the fluff C is scraped off and peeled off from the peripheral surface of the drum 19.
Winding efficiency of the fluff C by the felt 34 is improved. Further, as the operating time elapses, as the outer diameter of the clearer 29 increases due to the wound up fluff C, the clearer 29 gradually moves upward along both guide grooves 16a and 28a, as shown in FIG. Because it moves, one clearer 29 can be used for a long time. Therefore, there is no need to frequently perform maintenance and inspection of the blower 11, unlike in the past, and the effort required to do so can be saved.

Note that this invention is not limited to the configuration of the above embodiment, and for example, the drive mechanism for rotating the drum 19 may be configured with a pulse motor or the like, or the clearer 29 may be formed in a cylindrical shape, etc. It is also possible to arbitrarily change the shape and structure of each part without departing from the spirit of the invention.

Effects of the invention As detailed above, this invention rotatably supports a drum with a large number of ventilation holes formed on its circumferential surface at the suction port of a blower, and a drive mechanism for rotationally driving this drum. At the same time, by supporting the clearer which is driven and rotated in contact with the circumferential surface of the drum so as to be movable in the direction away from the axis of the drum, the air fluff adsorbed to the suction port of the blower is automatically and continuously removed. This is an industrially excellent device for removing fluff from the blower suction port, as it has the effect of facilitating maintenance work on the blower.
