Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fiber waste removal device for an endless belt type clearer applied to the drafting section of a spinning machine, which has a simple configuration and eliminates fiber waste attached to the clearer without using a special left drive means. It is designed so that it can be peeled off.

Roller drafting devices such as filament machines, combers, roving frames, fine spinning machines, etc. are equipped with a clearer device to remove fibers attached to the surface of the drafting roller or impurities contained in the fibers. .

There are various means and types of clearer devices like this, but from the viewpoint of operation and management, many are used in which an endless belt-type clearer material is actively rotated and brought into contact with the working surface of the drafting roller. ing.

In addition, felt, raised fabric, non-woven fabric, synthetic resin materials, etc., which tend to attract fiber waste and impurities, are used as such materials, but the fiber waste that adheres during use may accumulate. A cleaning device (fiber debris stripping device) is provided to remove fiber debris adhering to the clearer material, since this can destroy the cleaning effect on the mating roller or cause deposits to fall, damaging the product.

For example, FIG. 1 shows a clearer device in the drafting section of a wire drawing machine as a representative example, and the fiber waste peeling device is a cross-sectional view schematically showing various conventionally known devices, and the drafting section is a front bottom roller. 1. A group of bottom rollers including a second bottom roller 1a, a third bottom roller 1b, and a back bottom roller 1d, and a front top roller 2, a second top roller 2as, a third top roller 2b, and a back top. The rollers 2c are respectively placed under pressure.

The clearer devices include a bottom (under) clearer device 3 installed opposite to the bottom roller group and a top (upper) clearer device 4 installed opposite to the top roller group. An example of a belt-shaped structure is shown.

In these clearer devices, the above-described clearer material 5 is passed over clearer rollers 6 and 6a, respectively, with the clearer roller 6 serving as a tensioning roller and 6a serving as an actively driven roller.

The drive-side clearer rollers 6a are each rotated in the direction of the arrow by a suitable drive means, and the rotation is performed continuously or intermittently while being rotated back and forth to rotate the clearer material 5.

In addition, these clearer devices 3 and 4 are generally constructed of a frame whose left and right ends are supported by plate materials, and a support frame 7 is provided inside the clearer material 5 so that the clearer devices 3 and 4 can be detached and retracted from each roller group. ing.

Further, guide members 8 are resiliently provided on each of these support frames 7, so that the clearer material 5 is brought into contact with the surface of each roller group.

On the other hand, as such a device for removing fiber waste from the clearer material 5, various devices have been proposed and put into practical use, but all of them are actively driven to remove the fiber waste deposited on the clearer material 5. It was intended to peel off etc.

That is, reference numeral 9 indicates a peeling comb mainly applied to the top clearer device 4, which is fixed to the tip of a reciprocating swing lever 9a, and is brought into contact with the clearer material 5 by the weight of the peeling comb 9.

The swing lever 9a is connected to a special drive device, and its mounting connection portion is pivotally supported, so that when retracting, the swing lever 9a can be rotated together with the top clearer device 4 at the pivot portion and retracted.

Reference numeral 10 exemplifies a stripper type, in which a roller with a comb or a comb blade protruding from its circumferential surface is rotated in the direction of the arrow to peel off fiber waste, etc. in correspondence with the clearer material 5, and the peeled fiber waste, etc. It is removed by a suction nozzle 11 that is provided to face the area.

Reference numeral 12 mainly indicates a comb installed opposite to the pot clearer device 3, and the comb 12 is installed on an oscillating plate 13 and is configured to push up the plate 13 with a slight pressure.

The oscillating plate 13 is reciprocated by a suitable driving means, and the clarifier material 5 is moved by the comb 12.
Fiber waste etc. are removed.

Reference numeral 14 exemplifies a double plate comb that is placed oppositely with the clearer material 5 in between, and the combs 14a are pressed against the comb 14 by their own weight, a spring, etc., and are reciprocated individually or together.

By the way, all of these fiber waste removal devices are designed to remove fiber waste, etc. attached to the clearer material 5 by being actively driven. Further complication is caused by the need to keep these drives connected.

Therefore, handling and maintenance are troublesome, and breakdowns occur frequently.

Therefore, it is desired to develop a device that does not require any driving power or driving means, and can constantly peel off fiber debris and the like adhering to the clearer material 5 simply by simply installing the device.

The present invention has been made with attention to these points, and it is an object of the present invention to provide a peeling device that satisfies the above-mentioned needs.

However, in this invention, an upper open frame is formed through which clearer material can be passed, and between both side walls, a support member holding one end side of a companion plate formed of a thin steel plate is moored and supported. In addition to the mooring support,
The leading end side of the trailing plate is made to face the direction of movement of the clarifier and is curved to contact the clarifier material, and the leading end edge of the trailing plate forms a contact surface substantially parallel to the clarifier material to press the clarifier material. The structure is such that the two parts are brought into contact with each other.

The present invention will be explained in detail below based on the drawings, but the drawings show one example of a specific implementation of the present invention, and the present invention is not limited to these illustrated examples, but can be constructed based on the spirit described above and below. Even if the shape of the parts is changed or a part of the design is changed, the same implementation is possible.

FIG. 2 shows the peeling device 15 of the present invention applied to the top clearer device 4 illustrated in FIG. 1, which is supported by a support frame 7.

The peeling device 15 is composed of a frame and a trailing plate 19 held by the frame, and the leading edge of the trailing plate 19 serves as a comb plate.

As shown in FIG. 3 (enlarged view of FIG. 2) and FIG. 4 (plan view of FIG. 3), the frame body has side walls 16, 16 formed in accordance with the width dimension of the clearer material 50. is continuously integrated with the bottom plate 16c.

Further, the lower part of the side wall 16 has an engaging protrusion 1 at the center thereof.
6a, and a fitting groove 17 which is open downward is formed in the engaging protrusion 16a.

In the peeling device 15 of the present invention illustrated in FIG. 2, since there is a considerable distance between the upper surface of the support base plate 7 and the clearer material 5, an intermediate floor plate 16b is provided above the bottom plate 16c.

In the arrangement, support shafts 18 are implanted on both sides of the support base plate 70, and the fitting grooves 17 of the engagement protrusions 16a are fitted and held in the support shafts 18.

Note that, prior to this arrangement, the clearer material 5 is guided between the side walls 16.

The frame arranged in this way is attached to the support base plate 7 with its bottom plate 1
6c and is stably supported by the support shaft 18 in the longitudinal direction.

The support shaft 18 may be a screw shaft that tightens the fitting groove 17.

On the other hand, a detachable peeling plate 19 made of fiber waste or the like is attached to the frame body, and in the present invention, the peeling plate 19 is made of a thin elastic plate made of steel, and is curved so that the lower end edge is a clearing plate. The guide plate 19 is arranged so as to be substantially parallel to the clearer material 5, and the fiber waste etc. adhering to the clearer material 5 is peeled off at the leading edge of the guide plate 19.

FIG. 5 is a developed sketch showing the configuration and attachment of the trailing plate 19 in a frame without the intermediate floor plate 16b.
It is fitted and held in place.

The supporting member 20 is made by bending an iron plate into two as shown in the figure, and the top part is made into a circular curved surface for easy handling, and the upper end side of the trailing plate 19 is held between the two beak-shaped pieces 20a.

Further, both side end portions 20b of the beak-shaped piece 20a are formed to protrude from the width of the outer phase 19 and the top circular surface, respectively, and the end portions 20b are fitted into fitting grooves 21 formed in the side wall 16, respectively, so that the companion plate 19
hold.

The fitting groove 21 is formed by inserting the end portion 20b of the support member 20 while bending the companion plate 19 as shown in FIG.
The end portion 20b is shaped so as to be tilted and stably supported by the reaction force of the trailing plate 19, and is composed of an insertion groove 21a and an enlarged tilt holding groove 21b as shown in FIG.

Therefore, when inserted as shown in FIG. 6, the end portions 20b are prevented from coming off by the step portions of the insertion groove 21a and the enlarged tilt holding groove 21b, respectively.

The guide plate 19 is formed with such a length that its lower end edge 19a is pressed almost parallel to the clearer 5 when it is curved and stably held as shown in FIG. 19
It is recommended that b be configured so that it slightly rises from the clearer material 5.

Regarding this pressurization, if the pressurization force is large, the friction of the clearer material 5 will increase, so the guide plate 19 should be set at 0.01
Use one with a thickness of ~0.5 mm.

Further, when the length is short, the pressurized parallel portion is not formed,
The leading end edge 19b of the companion plate 19 is in the shape of thrusting into the clearer material 5 and obstructs the movement of the clearer material 5.

Therefore, care must be taken in selecting the trailing plate 19, but these can be selected freely if configured as follows.

That is, FIG. 8 shows a structure in which the curvature of the trailing plate 19 can be changed and adjusted. A beam 22 is fixedly installed inside the side wall 16, and a pressing screw 23 is provided on the beam 22.

The tip of the pressing screw 23 is placed against the center of a material (not shown) that is placed along the width direction of the trailing plate 19 and approximately in the center of the curve, and pushes the material toward the trailing plate 19 to uncurve the curve. It is configured to adjust and hold the leading edge 19b as described above.

Alternatively, the support member 20 of the trailing plate 19 can be held in a freely inclined position.

FIG. 9 shows a specific example of this, and shows only the -blade side.

That is, the enlarged tilting holding groove 21b of the fitting groove 21 provided in the side wall 16 is made into a blank hole, and the swing bracket 24 is pivotally attached to the outer surface of the side wall 16, and the bracket 24 is provided with a groove 25 corresponding to the enlarged tilting holding groove. Form.

Then, the end portion 20b of the bullet plate 19 supporting member 20 is fitted into the groove 25.

Further, the swing bracket 24 has a projecting piece 24a on one end side thereof.
is integrally formed with an adjusting screw 27, and the adjusting screw 27 is screwed into an angle bracket 26 which is also pivotally supported on the side wall 16.

With this configuration, the curvature of the companion plate 19 is reduced by the adjusting screw 2.
The swing bracket 24 can be adjusted by swinging by moving it in and out, and the position shown in FIG. 7 can be maintained.

Since the clearer fiber waste peeling device of the present invention is configured in this way, the fiber waste etc. attached to the surface of the clearer material 50 can be removed.
It is peeled off by the leading edge 19b of the trailing plate 19 and deposited on the upper surface of the trailing plate 19.

In addition, such an apparatus does not require any drive means for the peeling reservoir as in the prior art, and can completely eliminate the need for these devices.

Also, when installing it, it is extremely easy to handle, as it can be installed simply by arranging the frame and attaching the trailing plate.

Although the figure shows a device installed opposite to a top clearer device, it can be similarly applied to a pot clearer device as is or by improving the support shaft 18 of the support frame 7 and the fitting groove 17.

In addition, although the leading edge 19b of the companion plate 19 is shown as a simple cutting line, it may be actively formed with unevenness or grooves like a comb to actively remove adhering fiber debris etc. of the clearer material. It may be peeled off.
