Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for judging the quality of rush to select and remove, for example, bad grass that has been broken and cannot be supplied to a weaving machine from raw rush such as tatami mats and mats.

[0002]

2. Description of the Related Art In recent years, a large amount of rush fabrics such as tatami mats and mats imported from foreign countries are supplied to the Japanese market, and domestic rush farmers produce higher quality, higher value-added and more competitive grass products. Efforts are being made to improve quality day and night. For example, cut grass which is to grow to about 1.5 meters, cut it with mud, dry it, and set it on both sides in front of the weaving device in a state where it is made into a bundle of about 200 unbounds, for example. While throwing into the feeding section, and alternately flying into the warp gap of the weaving section two by two from the left and right direction,
The required tatami mats are woven.

[0003]

The rush to be put into the looms is, for example, sun-dried as described above, and the rush having a diameter of about 1 to 2 millimeters and a length of about 1.5 meters is handled during handling. If the rush is supplied to a looms loom in a state containing rush having such a broken part, the tatami of the fold of the broken part is dented or woven. Occasionally, the tatami is cut off, and the entire tatami mat at that portion is rejected or downgraded, thereby significantly reducing the commercial value. For this reason, conventionally, for example, when a producer finds broken grass by placing several hundred rushes in a bottomed cylindrical container and holding the container and shaking it manually, The grass was removed, and the grass was judged good or bad. However, if the container itself is enlarged and a large amount of rush is thrown in to perform quality screening, the whole becomes heavy, and a large amount of labor is required for the work of shaking the operator in the horizontal direction while holding it with hands or the like, Sorting by sufficient rocking was apt to be omitted. On the other hand, when a small container is used, the amount of grass that can be sorted in one sorting step is small, and there is a problem that the efficiency of sorting is poor.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and one object of the present invention is to reduce the labor of an operator by rotating the rotation shaft while rotating the rotation shaft while supporting the bottom portion of the eccentric shaft so as to freely rotate. It is an object of the present invention to provide a grass quality judgment assisting device that enables a user to easily visually recognize a grass having a broken portion by shaking a bottomed container portion storing a lower end side of the grass in a circumferential direction, without the need. . Another object of the present invention is to
It can be manufactured with a simple structure and at low cost, and mechanically shakes the lower end side of the rush without manpower to take enough time to perform sufficient shaking and sorting to determine the accuracy of grass quality. It is an object of the present invention to provide an apparatus for determining the quality of grass which can be improved.

[0005]

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 4
FIG. 1 shows a preferred embodiment of the present invention. In FIG.
A rotating shaft 32 rotatably supported in the vertical direction and the vertical direction on the support base 12, and a position eccentric from the axis of the rotating shaft 32, fixed to the rotating shaft and attached vertically. An eccentric shaft 14 and a bottomed container portion 16 whose bottom is rotatably supported with respect to the eccentric shaft are provided.

The apparatus 10 for judging the quality of rush of the present invention comprises:
For example, it is an auxiliary device for judging whether each piece of rush is good or defective when inspecting each piece of rush before putting it into a looms loom. . In FIG. 1, the support base 12 is supported by a floating (elastic) support via a hollow short cylindrical case 18 having a certain height and a floating support mechanism (elastic support mechanism) 20 provided inside the hollow of the case. And a base plate 22 to be formed. In the present embodiment, the base plate 22 is formed in a disk shape arranged in a horizontal direction so that its plane faces up and down, and a drive motor 24 is fixed to the lower surface thereof.

In the embodiment, the floating support mechanism 20 has three lower ends fixed to the upper surfaces of the bent pieces of three bracket members 26 fixed to the inner wall of the case 18 in an inverted L shape and projecting the bent pieces toward the center. It consists of three coil springs 28 arranged. Each coil spring 28 is vertically arranged so as to apply a spring force in the vertical direction, and the upper end thereof is fixed to the lower surface of the base plate 22. As shown in the figure, a gap H is provided between the upper edge of the case 18 and the base plate 22.
The base plate is floatingly (elastically) supported by the coil spring 28 at a position directly above the case 18 at a height position where the gap H can be formed and at a position separated in the height direction. . A hole (not shown) is formed in the center of the base plate 22 so that a rotation shaft 32 to be described later penetrates and is connected to the rotation shaft of the drive motor 24.

A hollow, cylindrical support tube 30 is erected in the vertical direction, that is, in the vertical direction, at a position substantially at the center of the base plate 22 and directly above the drive motor 24. A rotation shaft 32 is rotatably provided in the support cylinder 30 via a bearing 34 disposed at a required position in the support cylinder so that the center of the circular section is the rotation axis. The lower end of the rotating shaft 32 is connected to the rotating shaft of the drive motor 24 through a hole provided in the center of the base plate 22, and is driven to rotate in the vertical direction by the activation of the drive motor 24.

As shown in FIGS. 1 and 4, an eccentric shaft is integrally formed at the upper end of the rotating shaft 32 so that the position eccentric from the axis R of the rotating shaft is set as the axis Q. 14 is fixed in the vertical direction. In FIG. 4, the eccentric shaft 14 is
A part of the shaft body of the rotary shaft 32 is protruded further upward from the upper end of the shaft 0 by cutting or the like, for example, and is cut in a stepped manner. The bottomed container portion 16 is supported by the eccentric shaft 14 so that the bottom portion of the eccentric shaft 14 is freely rotatable. Since the bottomed container portion 16 engages with the eccentric shaft 14 so as to freely rotate, the bottomed container portion 16
The eccentric shaft 14 does not rotate around its center axis, but moves in a circular manner so that the orbit of the eccentric shaft becomes the orbit of the center of the bottomed container 16 in response to the orbital movement of the eccentric shaft 14.

In the embodiment, the bottomed container portion 16 has a container receiving member 36 whose bottom is rotatably supported on the eccentric shaft 14 and a container body 38 detachably mounted on the container receiving member 36. And 1 and 4, the container receiving member 36 is a short cylindrical member having a cylindrical tray shape and having a bottom, and a shaft connecting portion 44 having a small-diameter cylindrical member 42 protruding downward at the center of the bottom portion 40. Is provided. A bearing 46 is fixed inside the shaft connecting portion 44, and is fitted and fixed in a state where the upper end of the eccentric shaft 14 penetrates into the inner ring hole, whereby the shaft connecting portion is rotated to the eccentric shaft 14. While being freely supported, the bottomed container portion 16 is freely rotatably supported with respect to the eccentric shaft 14 having a vertical axis.

In FIG. 4, a spacer 50 is fixed to the upper end of the eccentric shaft 14 with a bolt, and a stop seat 48 is arranged and fixed so as to partially overlap the cutout portion at the upper end of the rotary shaft. In addition, the vertical movement of the bearing 34 is regulated to maintain the idling state of the rotating shaft 32 and the bottom of the bottomed container 16.

The container receiving member 36 is, for example, formed by forming a thin steel plate or the like into a cylindrical shape with a bottom, and is provided at its upper end with a vertically long inverted side having upper and lower ends open so that the upper part is slightly enlarged like a trumpet. A trapezoidal container 38 is screwed and fixed. As a result, the container body 3 is
8 is detachably mounted. The opening on the enlarged side of the upper surface is an insertion opening through which rush is inserted. The opening is, for example, about 1.5 meters in the hollow internal space of the bottomed container portion 16 constituted by the container receiving member 36 and the container body 38. A large number of long, thin, dry grasses are inserted from above, and the lower ends thereof are arranged in a state of being abutted against the inner bottom surface of the container receiving member 36. When the drive motor 24 is driven to rotate, the eccentric shaft 14 rotates around the axis of the rotating shaft 32 via the rotating shaft 32, and the bottomed container portion supported in an idling manner by this rotates the eccentric shaft 14. It moves around so as to be shaken laterally along the orbit.

Further, in this embodiment, as shown in FIG. 1, the lower end is fixed to the base plate 22 of the support base portion 12 to prevent the bottomed container portion from rotating together with the eccentric shaft 14 when rotating around. A stop 52 is attached. In the embodiment, the locking body 52 has a long bolt 5
4 and the lower end is bent into an L-shape and fixed on the base plate 22 with screws.

The locking member 52 is formed of an elongated metal plate-like member, and the upper end thereof can move to some extent by following a horizontal swing of the bottomed container 16 in a leaf spring shape. . Since the base plate 22 and the bottomed container portion 16 are connected and fixed, the bottomed container portion 16 follows the rotation of the rotating shaft 32.
Can be prevented from rotating together. Although not shown, a power supply wiring is connected to the drive motor 24, and the drive motor 24 may be turned on and off by, for example, stepping on or releasing the foot by a foot switch or the like. .

Next, the operation of the embodiment of the apparatus for judging the quality of grass will be described. When the drive motor 24 is turned on to rotate the rotary shaft 32 about the vertical direction,
The eccentric shaft 14 at the upper end rotates around at a position eccentric with respect to the center axis of the rotating shaft 32. In other words, the outer peripheral edge of the rotary shaft 32 moves at the same angular velocity as the rotary shaft 32 while being fixed to the rotary shaft. At this time, the bottom of the bottomed container portion 16 is rotatably supported by the eccentric shaft 14 via the bearing 46 so that the bottom portion of the container portion 16 can rotate around the rotation axis in a state of being fixed to the rotation shaft 32 of the eccentric shaft. Irrespective of the rotation, the low / low container section 16 itself does not rotate around the axis, and moves around the eccentric shaft while being supported by the eccentric shaft 14 so that the center of the bottom moves. For example, as shown in FIG. 5, the entire bottomed container portion 16 orbits along the orbit of the eccentric shaft 14 so as to draw a large orbit P while using the eccentric shaft 14 as a central axis. Basically, a large number of dry grasses whose lower ends are inserted into the lower / lower container portion 16 are shaken while being swung in the circumferential direction. As a result, as shown in FIG. The weeds that have been exposed are made visible, and the operator can easily visually observe them and pull them out with the apparatus stopped to select and secure only good-quality weeds.

In this embodiment, the lower end of the rotating shaft 32 is floatingly or elastically supported by a coil spring 28 as an elastic member.
As shown in (2), when the bottomed container portion 16 at the upper end of the rotary member 32 rotates in synchronization with the rotation of the rotating shaft 32, centrifugal force acts on the upper end, and the elastic member absorbs the swinging operation in the circumferential direction. However, at this time, as shown in FIG. 3, the base plate 22 to which the support cylinder 30 is fixed moves horizontally in the horizontal direction as shown by the arrow, so that the bottomed container portion 16 on the upper end side also has It is a revolving motion accompanied by a revolving stress in a reflex manner, and this causes the lower end of the rush to oscillate greatly in the lateral direction, thereby efficiently and reliably assisting in the determination of defective or non-defective rush. That can be done.

Further, in this embodiment, a locking member 52 for preventing co-rotation is fixed so as to connect the base plate 22 and the bottomed container portion 16, and this locking member 52 is formed in a leaf spring shape. Since it can be moved elastically to some extent, it can effectively prevent the rotation shaft 32 from co-rotating with the bottomed container portion 16 while securing the function of amplifying the roll by the spring as an elastic member, It is intended to effectively assist in determining the quality of rush.

The apparatus for judging the quality of rush of the present invention described above is not limited to the configuration of the above-described embodiment, but may be arbitrarily modified without departing from the essence of the invention described in the claims. May go. For example, the elastic member is formed of a coil spring in the embodiment,
For example, a spring-like support configuration may be made by combining a rubber member, a leaf spring-like metal member, or a synthetic resin.

The eccentric shaft 14 is formed integrally with the upper end of the rotary shaft by cutting or the like. For example, a hole is formed in the peripheral side wall of the support cylinder, and one end is fixed to the rotary shaft side. The protruding rod is projected laterally through the hole, and the eccentric shaft 14 is fixed vertically upward from the protruding rod, and the bottomed container portion is rotatably supported on the eccentric shaft via a bearing. You may do so. Further, the container receiving member 36 of the bottomed container portion 16 may have a structure having only a free rotation with an eccentric shaft having no bottom plate, and a container body as a bottomed cylinder may be attached to the upper surface side. The bottomed container section 16
It may be integrally configured so that it cannot be mounted, or may be configured to be removable as in the embodiment. In addition, the shape of the case 18 of the support base 12 and the shape and configuration of the base plate 22 may be arbitrarily set.

[0025]

As described above, according to the auxiliary apparatus for judging the quality of rush of the present invention, the rotating shaft connected to the drive motor and rotating about the vertical direction, and the position eccentric from the axis of the rotating shaft. An eccentric shaft fixed in the vertical direction and fixed to the
And a bottomed container portion having an insertion opening for vertically inserting rush into the upper surface side, the bottom portion of which is rotatably supported with respect to the eccentric shaft. By rotating the bottomed container part so that it can rotate freely, the bottomed container part that houses the lower end of the grass can take a desired time in the circumferential direction without requiring the labor of the operator. It is possible to significantly improve the accuracy of the quality judgment of the grass having a broken portion by swinging the grass.

The bottomed container portion has a container receiving member whose bottom is rotatably supported with respect to the eccentric shaft, and a container body detachably attached to the container receiving member. Therefore, the depth of the container body and the size of the inner bottom surface with respect to the container receiving member can be changed as necessary, thereby effectively changing the grass body while replacing the container body according to the amount of grass to be determined to be put. Can be performed.

Further, since the lower end of the rotating shaft is floatingly supported by the elastic member, the base plate is largely horizontally supported by the floating support of the elastic member in combination with the centrifugal rotation of the bottomed container at the upper end. It is possible to amplify the swing of the bottomed container portion by swinging, thereby efficiently generating a shaking operation for assisting the quality judgment of the rush.

Further, since the elastic member is constituted by a spring, the elastic member can be realized by a simple constituent member, so that a simplified configuration of the whole apparatus and a reduction in cost can be realized.

Further, since the locking member is provided for preventing the bottomed container portion from rotating together when the eccentric shaft rotates around, it is possible to prevent the bottomed container portion from rotating around when rotating around the eccentric shaft. It is possible to effectively assist the quality judgment of the rush by shaking the bottomed container part.
