Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to each saucer of a cutting conveyor for cutting long agricultural products such as long onions and asparagus into a certain length, and sorting the long agricultural products according to size. An edge aligning and supplying device for long agricultural products, which automatically supplies the long agricultural products with one side end aligned to each saucer of the sorting machine, is suitable for use in agricultural product sorting and packaging facilities.

(Prior Art) Conventionally, many devices have already been developed for automatically supplying substantially spherical fruits one by one to each saucer of a fruit sorter, but a sorter for long agricultural products such as asparagus and long onions. There is not yet a device that automatically aligns one side edge of each saucer and each tray of the cutting conveyor and supplies one by one, and the worker manually aligns one side edge and supplies one by one. It is in the actual situation.

On the other hand, as an end face aligning / supplying device for supplying a long material such as a steel pipe or a steel bar to the subsequent bundling step with one side end aligned, one disclosed in JP-A-57-85720 is known.

In the conventional one of the above-mentioned publication, a long material such as a straight steel pipe, which is placed side by side over four take-up conveyors parallel to the conveying direction and is supplied one by one, has the same length as the length of the long material. 8
~ 90% of the length is equally placed on each of the four lined conveyors arranged in parallel at equal intervals, and the sheets are sequentially placed between the standing attachments arranged at equal intervals and conveyed, and arranged on the side of the conveyance start end side. The end face correction conveyor is used to laterally move the laterally-oriented long material placed over the four-row alignment conveyor by the uneven amount to align the end surfaces of the long-length material from the end portion of the four-row alignment conveyor. The long material is supplied to the latter stage.

(Problems to be solved by the invention) The above conventional one can be applied to a straight long product such as a steel pipe or a steel bar, but when the conventional product is used for a long agricultural product, a long agricultural product is In general, there are many things that are not straight but are bent in a bow shape, so the following problems are assumed.

That is, in this conventional one, even if a slightly curved long agricultural product is placed between the respective standing attachments of the four-row alignment conveyor, the curved long agricultural product is divided into 80 to 90% of its length. Since it will be restrained and held between the standing attachments at four places, when the long agricultural products are laterally moved by the end face correction conveyor, the bent long agricultural products may be strongly rubbed against the standing attachments or may not move laterally smoothly. The problem of damaging long agricultural products can be considered.

In view of the above circumstances and the above problems, the present invention is capable of automatically aligning one side end of a long agricultural product without damaging the long agricultural product, even if it is curved in an arc shape or the like. It is an object of the present invention to provide an edge aligning and feeding device for long agricultural products that can be fed one by one.

A conveyor with a crosspiece that receives and conveys it so that it is placed between the crosspieces, and a long agricultural produce is provided laterally while being in contact with the one end of the long agricultural product that is provided on the side of the crosspiece conveyor and that is conveyed on the crossed conveyor. An edge aligning means for moving and aligning the one side edge, and supplying the long agricultural products conveyed on the conveyor with the crosspiece one by one to the next step from the conveying end portion. Configuration of supply device Those were.

Thus, in the present invention, the long agricultural products that are sequentially supplied one by one from the end portion of the supply conveyor are sequentially received one by one between the bars of the conveyor with the crosspiece, but about 1/4 to 1/2 of the length of the long agricultural product. It will be accepted so that the middle part of the long agricultural product will be placed between the horizontal bars of the length of, and about half or more of the long agricultural products will be on the side of the end of the horizontal bar, not between the horizontal bars. Since it is free from being restrained by a crosspiece, even if long agricultural products are bent in a bow shape,
When the horizontal product is laterally moved by the edge aligning means, the long agricultural product can be smoothly laterally moved without being strongly rubbed against the crosspiece, and the long agricultural product is not damaged.

In the present invention, it is preferable that the predetermined interval is an interval in which two or more laterally long agricultural products are not mounted between the crosspieces, and there is a slight margin for one long agricultural product. It is preferable that each of the crosspieces is made of a soft elastic material such as rubber or sponge, and the cross-sectional shape thereof is semicircular or trapezoidal. Further, the edge aligning means is a belt conveyor having a belt surface substantially vertical. In addition, the end portion of the belt is disposed closer to the conveyor with the crosspiece than the start end, and the traveling speed of the belt surface in contact with one end of the long agricultural product in the transport direction is the conveyor with the crosspiece. It is preferable that the transport speed is the same as the transport speed.
