SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the above-mentioned prior art. In the middle of conveyance by a belt with a crosspiece, a taper-like long object is moved in the width direction by a feed rotary member. It is possible to pack the taped elongated object such that its thick end abuts on one inner side surface of the box body, so that it can be packed in the box body. In order to achieve a satisfactory quantitative packing in an aligned state with less gaps,
Its purpose is.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention conveys the direction of a long tapering object which is conveyed by a belt with crosspieces in a sideways lying sideways direction orthogonal to the conveying direction. Detected by the direction discrimination sensor in the middle of the process, and the detection signal is used to selectively operate each feed rotating body that rotates so that the thick end of the tapered long object is moved toward the side end of the belt with crosspieces. By transmitting the rotation of the rotating body to the tapered elongated object, the tapered elongated object can be placed in each of the recesses that are provided outwardly in the guide plates that are erected on both sides of the crosspiece belt. After pushing out, the thick end is projected to the outside of the side end of the belt with crosspieces, and the thick end is conveyed while abutting against the inclined surface connected to the downstream side from the concave portion, and then the thick end is belted with crosspieces. Along the side edge of the It is intended to provide an end gathering methods tapered long product by - With Centering Flange belt conveyor, characterized in that it has so go being.

[0008]

The taper-like long object such as carrot is placed on the upstream side of the belt with crosspieces from the required supplying device or the like, and the thick ends thereof are placed sideways so that the thick ends thereof are alternately inverted. When the tapered long object is conveyed to the predetermined position by the belt with crosspieces, the direction is detected by the direction determining sensor, and the detection signal causes the feed rotary member arranged downstream thereof to operate.

Each of the pair of feed rotary members is made of sponge rubber or the like, and by transmitting the rotation to the tapered elongated member, it rotates in a fixed direction so as to feed in one direction in the longitudinal direction. Therefore, by the above-mentioned rotation, the long end with the taper is extruded with its thick end toward one side end in the lateral width direction of the crosspiece belt.

When the object to be conveyed is pushed out to the one end side, the thick end enters the concave portion of the concave portion outwardly toward the guide plate, whereby the thick end is moved from the side end of the belt with crosspieces. , Once projected to the outside.

The thick end projecting outward is conveyed downstream while being in contact with an inclined surface which is located on the downstream side of the recess and is inclined toward the side end of the crosspiece belt. It is conveyed toward the edge while being attached to the guide plate.

[0012] Therefore, if the end aligning method is adopted for the automatic box packing of the tapered long object, it becomes possible to pack the tapered long object in a state where the thick end thereof is brought close to the inner surface of the box. Therefore, by alternately changing the direction of the tapered long object and placing it on the belt with crosspieces, the thick end of the long piece is brought close to the side end of the belt with crosspieces, so that the taped long article can be packed in the space of the gap. It is possible to have a cleaner alignment than no.
