2. Description of the Related Art Heretofore, in order to pack a long tapered object having a thick end like a carrot using an automatic packing device, it is only necessary to supply ginseng or the like to a transfer belt at random. Therefore, carrots and the like lying on the transfer belt may be thrown in the same direction one after another, and when thrown into the box in such a state, the carrots and the like stored in the box body become thick. The thick end portion is further stacked on the end portion. As a result, although the stacked thick end portion reaches the opening of the box body, the thin end portion and the opening are closed. A space is left between the head and the part, so that the required amount of ginseng and the like cannot be packed.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks caused by the conventional method. The present invention relates to a long object which is randomly transferred by a transfer conveyor so that a desired box can be packed. The transport direction of ginseng etc. is to be alternately reversed so that it is transported alternately such that the thin end comes before the thick end first, so if necessary, The long end of the long object put in the box body is piled up on the thick end by allowing the long end of the long object to be transported with the thick end and the thin end inverted. It is an object of the present invention to make it possible to pack ginseng and the like that can fit in the box body.

[0004]

According to the present invention, in order to achieve the above object, a tapered long object having a thick end portion and a thin end portion is supplied on a transfer belt at random. and gradually, the long object is, the predetermined transfer axis of the transfer belt by the guide mechanism, so as to one destined transported vertically long state, per long object of the thus transferred, the direction discrimination sensors instrumentation set To determine the direction of the leading end of the thick end or the leading end of the narrow end, and input the pointing discrimination output from the direction discriminating sensor to the electric controller based on the judgment result, and the electric controller sequentially transfers the discrimination. When the direction of the long object is alternately determined to be the repetition of the thick end advance and the narrow end advance, based on this determination, when the long object should be transferred in the same direction By electrical controller Running a power source, a reversing rotary body that is instrumentation set downstream of said direction discrimination sensor is required angle by rotating, thereby the inversion becomes said transfer axis and the swash交状of the long product The transferred long object comes in contact with the sliding receiving surface of the rotating body, and is transferred in the same direction, and the electric controller reverses the long object instead of the same direction. When it is determined that it should be performed, the power source is operated by the electric controller to reverse the reversing rotating body by a required angle, and the long object transferred by the reversing rotating body is used for the reversing. The impact source is brought into contact with an impact sensor attached to the rotating body, and at this time, the reversing rotating body is moved backward by the operation of the power source based on a signal output from the impact sensor, whereby the impact sensor is in contact with the impact sensor. Rotate the end of a long object DOO and in which, with the transfer by the transfer belt, by reversing the long product, changing its orientation, as transfer by the transfer belt at the turning state is continued, of the long product sequentially separately prepared Carrying
By feeding it to the feed belt,
Place the product in a lying position, and sequentially place these long objects on the transport bell.
It is intended to provide a method of reversing and transporting a tapered long object such as ginseng packed in a box, wherein the long object is put into a box body by falling from the box .

[0005]

[Action] When a tapered long object is sequentially provided at random on a transfer belt, a guide mechanism guides the long object.
A long object is transported on the transport axis of the transport belt in a vertically long state with the leading end at the thick end or the leading end at the narrow end.

The long object transferred in this manner is:
A direction discriminating sensor provided facing the transfer belt determines whether the long object has been sent before the thick end or transferred before the thin end. The pointing discrimination output, which is the discrimination result, is input to the electric controller, and here, a judgment is made as to whether or not the long objects sequentially transferred repeatedly alternate between the thick end leading and the thin end leading. Will be given.

[0007] Next, the electric controller determines whether the long object should be transported in the same direction or the direction should be reversed to be redirected and transported according to the above-described determination. With the reversing output of the electric controller, the rotating body for reversing is rotated by a required angle by a separately prepared power source, whereby the long object contacts the sliding receiving surface of the rotating body for reversing, It is transported in the same direction.

On the other hand, in the case where the above-mentioned reverse reversal transfer is required, the electric controller also operates the power source with the reversal output, whereby the reversal rotating body is reversely moved. long member that incoming to strike the impact sensor of the reversing rotor.

Accordingly, the output of the impact sensor activates the power source, so that the rotating body for reversing moves backward, so that the end of the long object in contact with the impact sensor receives the rotating power,
When the long object is transferred by the transfer belt, the long object is inverted and transferred by the transfer belt in a deflected state.

In this manner, the long object whose transfer direction has been alternately changed is then sent to a separately provided transfer belt (not shown), where it is placed in a reclining state in a direction orthogonal to the transfer direction. Long objects that are sent as they are and that fall sequentially from the conveyor belt are put into the box.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Prior to describing the method of the present invention in detail with reference to the drawings, a reversing device which can be used for carrying out the method will be described below with reference to FIGS. Is provided with a guide mechanism 2.

The above-mentioned guide mechanism 2 transports a long tapered object 3 randomly provided on the transfer belt 1 while being guided on a predetermined transfer axis A of the transfer belt 1. In the illustrated example, a pair of guides 2 are formed on the transfer belt 1 so that the tapered through-hole 4 is formed in the transfer direction B.
a and 2b are provided.

The guide mechanism 2 is not limited to the above-described embodiment, but the transfer belt 1 is formed by a V-belt, and the lowermost part of the V-belt coincides with a predetermined transfer axis A. Is also good.

Next, on the downstream side of the guide mechanism 2, a direction discriminating sensor 5 is provided in the direction perpendicular to the transfer direction B, directly above the transfer belt 1 and close to the passage 4. The long object 3 that has been transferred is
It is determined whether the narrow end portion 3a is ahead or the thick end portion 3b is forward. At this time, the direction determination sensor 5 displays the image of the long object 3 that has entered. Optically grasped ones are adopted.

On the downstream side of the direction discriminating sensor 5, a rotating body 6 for reversing is located just above the transfer belt 1, and
By the vertically mounted rotation shaft 6a deviated from the predetermined transfer axis A,
Is rotatably so as So設 sideways, by the operation of the power source 7 due to such explicit rotary solenoid Figure 2,
By driving the vertical rotation shaft 6a, the reversing rotating body 6 is selectively rotated in the directions of arrows R ₁ and R ₂ in FIG.

Further, a vertically mounted rotating shaft 6a of the reversing rotating body 6 is provided.
Is disposed on the upper side of FIG. 1 which is a plan view with respect to the predetermined transfer axis A in the case shown in FIG. A slide receiving surface 6b for the scale 3 is formed. here,
The sliding receiving surface 6b shown in FIG. 2 is a vertically mounted roller 6c on the lower surface so as to be rotatable.
However, only a required number of the rollers 6c are provided, and 6d in the figure is a rotation shaft of the roller 6c.

Therefore, when using the sliding receiving surface 6b, the long object 3 transferred in the transfer direction B comes into contact with the sliding receiving surface 6b formed by the large number of rollers 6c. , And are sent to the downstream side while sliding smoothly.

Further, in the reversing device, reference numeral 8 denotes an electric controller, which includes a long object 3 sent from the direction discriminating sensor 5 by the transfer belt 1.
But whether the previous butt portion 3b, with directional discrimination output S ₁ which determines whether the preceding Hosotan portion 3a is inputted,
Its output is connected to a power source 7 above, thereby, an electrical controller 8 which receives the directional discrimination output S ₁ of the can, the inverted output S ₂ for transmitting to determine the later predetermined matters the contents, the as TateSo rotating shaft 6a are also available rotated in a direction of the R ₁ or R _2.

In order to timely transfer the long object 3 using the above-mentioned reversing device, first, the transfer belt 1 in the device is used.
In the meantime, one long object is randomly provided to the user, and when the long object is transferred by the transfer belt 1, the long object 3 is moved by the guide mechanism 2 from the passage 4 through the guides 2 a and 2 b shown in FIG. The long object 3 is sent on the predetermined transport axis A in the transport direction B in a vertically long state.

In this manner, the elongated object 3 in the vertically elongated state may be fed with the narrow end 3a side first or the thick end 3b.
Comes first, and at this time, for the long object 3 sequentially sent, it is determined which side is ahead.
Was determined by the direction discriminating sensor 5 above, it is to enter into an electrical controller 8 directional discrimination output S ₁ which emits a result.

Therefore, the electric controller 8 determines whether the direction of the long object 3 sequentially sent is alternately repeated between the leading end 3b and the leading end 3a. Is determined, and based on this determination, the electric controller 8 determines whether the incoming long object 3 should be transported in the same direction or inverted and transported. ₂ is input to a power source 7 such as a rotary solenoid.

[0022] Therefore, now, the inverted output S ₂ of the above, per long object 3 came transported, this, for example Hosotan 3
In the preceding state of a, if it is based on the determination that the transfer should be performed in the same direction, the vertical rotation shaft 6a is rotated by the operation of the power source 7, whereby the reversing rotating body 6 is rotated. From the position where it has been arranged parallel to the predetermined transfer axis A until then, it is rotated by a predetermined angle α in the direction of arrow R ₁ , whereby the reversing rotator is moved with respect to the transfer axis A. 6, the sliding receiving surface 6b is in an oblique state.

As a result, the long object 3 transferred by the transfer belt 1 as shown in FIG.
Is transported in the transport direction B by the transport belt 1 while sliding, after one side thereof contacts the slide receiving surface 6b.

Next, said inverted output S _2, the long object 3 came transported, as illustrated in FIG. 1 (B), not prior state of Hosotan portion 3a, this If it is based on the decision that the transport should be reversed,
The operation of the power source 7, the position that has been only rotated a predetermined angle α as described above, and than returning the inverted rotary member 6 in the direction of the arrow R _2, thereby, the reversing rotation body 6 is given The transfer is performed on the transfer axis A so as to be parallel to the transfer direction B.

Therefore, at this time, the narrow end 3a of the long body 3 transferred by the transfer belt 1 is
The impact sensor 6e will be impinge on, this time, the signal S ₃ output from the shock sensor 6e is input to an electrical controller 8 of the, or the output S ₄ from the electrical controller 8 based thereon, directly is operated the power source 7 by the signal S _3, thereby, as indicated by a chain line in FIG. 1 (B), again by a predetermined angle α reversing rotary member in the direction of the arrow R ₁ 6 is rotated.

In this way, the narrow end 3a of the long object 3 is rotated upward by the rotation of the reversing rotator 6 in the drawing, and is transported by the transport belt 1. Therefore, the long object 3 rotates counterclockwise as indicated by the dashed line, and the thick end 3b reverses to the preceding state, and is transferred in the transfer direction B while slidingly contacting the slide receiving surface 6b. Go being.

Here, the illustrated sliding receiving surface 6b is formed by the roller 6c as described above, so that the tapered long object 3 undesirably has a large resistance in sliding contact with the sliding receiving surface 6b. In this manner, the tapered long object which is alternately sent in a different direction without being received is sent onto a separately prepared transfer conveyor (not shown) as described above. The long object 3 placed one by one in the width direction is dropped into the box body 9 shown in FIG. 2 so that desired packing can be performed.

[0028]

Since the method of the present invention can be carried out as described above, when a long object having a taper such as carrot is packed in a box, the narrow end and the thick end of the long end are raised. It can be transported alternately with reliability and therefore
The elimination of the thick end portion being concentrated and piled up on one side of the box can be efficiently realized by an automated device.
