Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading / conveying apparatus for sequentially transferring conveyed objects such as carrots, radish and other root vegetables one by one to the next sorting step.

2. Description of the Related Art Conventionally, as the above-described crop conveying apparatus, for example, locking projections are formed on an outer peripheral surface of an endless rotating belt at a predetermined pitch, and the transported object is sequentially placed and locked by each locking projection. Then, one that is configured to be placed and conveyed one by one, or a pair of left and right endless rotation bands that support freely rotatable rollers at a predetermined pitch and one to-be-conveyed object between each roller. A device configured to be placed and transported has been considered.

[0002]

However, in the above-mentioned conventional structure, it is not always sure that the crops, which are the objects to be conveyed, are placed and guided one by one in a predetermined posture between the locking projections and the rollers. However, in the former conventional structure, the locking projection has two
Problems such as when more than one piece is placed or when no crop is placed, and in the latter conventional structure, the crop is placed across a plurality of rollers, so that the predetermined pitch is eventually set. They could not be placed and conveyed one by one without fail.

The present invention solves the above-mentioned disadvantages and sends out the objects to be conveyed one by one, for example, in the subsequent sorting step so that this type of crop can be accurately sorted.

[0004]

A characteristic construction of a one-piece feeding and conveying apparatus according to the present invention adopted to achieve the above-mentioned object is that conveying bodies are arranged side by side in a posture in which a longitudinal direction intersects the conveying direction. The respective mounting surfaces of the side-by-side transfer bodies are configured to be inclined surfaces that are lower on the lower side in the transfer direction, and the relative vertical position changes between the adjacent transfer bodies. The transport object placed on the transport surface is configured to be sequentially fed toward the transport lower side, and the transport surface has a terminal exit portion on the transport terminal side in the transport lateral width direction. It has a width corresponding to one piece of the conveyed object, and is configured such that the conveying start end side is wider than the terminal exit portion, and the lateral side edge of the conveying surface is at one lateral side of the conveying surface. Along with the contact guide surface for contacting the object to be conveyed along the conveying direction. A guide body composed of a moving endless rotation band is provided, the other lateral side portion is opened, and the guide body is moved in the conveying direction so that the contact guide surface protrudes toward the other lateral side toward the conveying end portion side. In addition, it is provided so as to be inclined with respect to the conveying surface, and the supply position of the conveyed object on the conveying surface is set to a position near the guide body side away from the opened other lateral side at the wide conveying start end portion. It is in. Further, in constructing the one-piece feeding / conveying device, as described in claim 2, the conveyed object dropped from the conveying body group is collected on the other lateral side of the conveying surface and returned to the conveying start end side. It is preferable to provide a reducing device.

[0005]

The operation of adopting the above configuration is as follows. That is, the respective transporters relatively move up and down, and due to the inclined mounting surface of the transporters, the transported object sequentially moves while moving to the transporter on the lower side. By repeating such a feeding operation, the conveyed objects which are vertically overlapped are collapsed and leveled, and the conveyed state is such that the conveyed objects are less overlapped toward the end of the conveyance on each conveying body. The transport surface formed by each transport body is configured so that the transport lateral width becomes narrower toward the transport terminal end side, and on the transport terminal end side of the transport surface, the terminal exit portion corresponds to one transported object. It is configured to the width. Moreover, the contact guide surface for contacting the object to be conveyed is formed on one lateral side of the conveying surface along the side edge of the conveying surface by an endless rotation band that is rotated in the conveying direction. Since the guide body is provided so as to be inclined toward the conveyance direction so that the contact guide portion protrudes laterally toward the other end of the conveyance, the guide body guides the contact guide to the conveyed object to guide the object. The conveyed product is assisted in the conveyance to the lower side of the conveyance, and is pushed from one lateral side to the other side during the conveyance. as a result,
Since the transferred object is prevented from staying on the transfer body, the transferred object is pushed laterally while reliably and quickly transferring it to the lower side of the transfer, and the transferred object pushed laterally is moved. Of these, the surplus transported object is dropped and removed from the open lateral other side of the transport surface, and only one transported object remains on the transport surface at the transport end, and that one transported object is transferred to the next process. Items will be sent out in sequence. According to the configuration of claim 2, in addition to the above-mentioned action, on the other side of the transport surface,
Since there is provided a reducing device for recovering the transported object removed from the transport surface and returning it to the transport start end side, at the transport end portion of the transport surface, each one can be sent to the subsequent process. Thus, the transported object excluded from the other side of the transportation surface can be efficiently returned.

[0006]

According to the structure of the first aspect, it is possible to solve the overlapping of the objects to be conveyed and to provide a conveying device capable of feeding the conveyed objects one by one with high accuracy. When used in an automatic sorting apparatus for other crops such as root vegetables, it is possible to accurately sort the weight rank of this type of crop. According to the configuration of claim 2,
In addition to the effect of the configuration according to claim 1, the transported object excluded from the transport surface is efficiently returned to realize efficient one-piece delivery while circulating the surplus transported object, which is even more efficient. Good sorting work can be performed.

In the one-piece feeding and conveying device 4, an upper placing surface 17a having a front-rear width substantially the same as the width (thickness) of the object to be conveyed A is lowered downward in the conveying direction of the object to be conveyed A. The transporting body 17 configured in the tilted position is set to the transported object A.
The transport surfaces 17A are arranged in parallel along the transport direction of No. 1 and each transport body 17 is vertically moved at a predetermined pitch, and adjacent transport bodies 17 are vertically moved in opposite directions. The drive timing is set and configured.

That is, as shown in FIG. 1, a large number of carriers 17 are arranged in parallel along the carrying direction, and the odd numbered carriers 17 are integrally driven as a first group in a reciprocating vertical movement at a constant pitch. In addition to the above configuration, the even-numbered transport bodies 17 are configured to integrally reciprocate vertically as a second group. More specifically, as shown in FIG. 2, the first group of carriers 17 are integrally connected by the first connector 19a, and the second group of carriers 17 are integrally connected by the second connector 19b. Connect each connecting tool 19a,

The drive system is configured to move up and down. Here, the drive timing is set so that the forward transfer speed of the transfer body 17 and the rotation speed of the endless rotation chain 14 in the sorting device 7 are synchronized to smoothly transfer the object A to be transferred.

Then, as shown in FIG. 3, the lateral width of each carrier 17 is narrowed toward the terminal end side of the carrier, and the terminal exit 16B on the terminal end side of the carrier is above the carrier 17. One object A to be transferred is placed, and each transfer body 17 is inclined so as to be at a lower level toward one end side in the transfer lateral width direction. It is configured to be laterally displaced one after another to be placed. Further, on the lateral side portion on the high level side in the lateral direction of conveyance, the vertical axis is moved along the lateral edge of the conveying surface 17A at a speed substantially the same as the conveying speed so as to contact the object A to be conveyed. The guide body 25 consisting of an endless rotation band that rotates around the core,
The object to be conveyed A is arranged so as to cover the entire area of the conveyance path.
