Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention automatically transports so-called long vegetables, such as carrots, radishes, and cucumbers, one by one, and automatically sorts, for example, grades. The present invention relates to a carry-out device for carrying out.

[Conventional technology]

 Conventionally, the unloading work is generally performed manually.

[Problems to be Solved by the Invention]

In the above-mentioned manual work, it is possible to reliably carry out the single unit, so that the sorting work in the subsequent process can be performed accurately and
Although it can be carried out smoothly, there is an adverse effect that the labor load on the worker becomes large when the amount of processing increases, and automation of such carrying-out work has been desired.

It is an object of the present invention to provide a carry-out device for sorting long vegetables, which can automatically carry out reliable single-pieces with a relatively simple structure.

[Means for Solving the Problems]

The carrying-out device for sorting long vegetables according to the present invention includes a transporting body with a locking projection that scrapes up and transports the transported object obliquely upward from the lower part of the hopper that stores a large number of transported objects, A through hole through which the transported object can pass is formed in an area other than a predetermined mounting portion of the transported object between the respective locking projections of the transporting body, and an object which has passed through the through hole and dropped during the scraping and transporting process is formed. The present invention is characterized in that a reducing device for returning the conveyed object into the hopper is provided.

The operation and effect of this characteristic configuration are as follows.

[Action]

The transported object stored in the hopper is placed and transported from below the hopper while being sequentially scraped up by the respective locking projections of the transport body. At this time, even if two or more objects to be conveyed are erroneously placed on the respective locking protrusions, the extra ones pass through the through holes of the carrier and are then returned to the inside of the hopper via the reducing device. Therefore, at the end of conveyance of the carrier, the object to be conveyed is unloaded at predetermined intervals.

〔The invention's effect〕

Therefore, according to the present invention, it is possible to automatically carry out the selection of long vegetables, and moreover, it is possible to reliably carry out the individual vegetables and to improve the accuracy of the selection in the subsequent process. Moreover, since the extra transported object is selected and returned through the through hole of the transport body, a dedicated complex for selecting and extracting the extra transported object on the transport body in synchronization with the transport speed. It is possible to simplify the entire device without using any special extraction means. In addition, since it is carried out obliquely from the lower part of the hopper, there is also an advantage that it is easy to set the height of the ground at the hopper input port and the conveyance end part to a level at which work can be easily performed.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 5 shows an automatic sorting device that automatically sorts long vegetables such as carrots into grades by weight sorting. This sorting device carries out a hopper (1) for storing a large number of objects (a) to be sorted, and one object to be sorted (a) sequentially from a lower portion of the hopper (1) at predetermined pitches in an obliquely upward direction. The carrying-out section (2), a measuring section (3) which is connected to the carrying-out end section of the carrying-out section (2) and automatically measures the weight while laterally transporting each of the objects to be sorted, and the measurement result in the measuring section (3). The sorting unit (5) automatically sorts and collects a plurality of collecting tools (4) on the basis of the sorting unit (4).

The carry-out part (2) is provided at a lower part inside the hopper (1) over substantially the entire length thereof, and the articles to be sorted stored in the hopper (1) are sequentially fed laterally to the outlet (6) on one lateral side. The first transfer device (7) carried out from the first transfer device and the second transfer device (8) for sequentially scraping up and transferring the object to be sorted (a) falling from the terminal end of the first transfer device (7) while diagonally moving upward. ) And each transfer device (7), (8) is an electric motor (9)
Is configured to be driven synchronously.

As shown in FIG. 3, the measuring unit (3) is a weighing unit which is displaced downward by the weight of the object (a) to be sorted, below the conveyor belt (12) for placing and carrying the object (a) to be sorted. The table (13) is provided with the balance spring (14) and the damper mechanism (15) returned to a predetermined position and urged, and the difference in the downward displacement of the weighing table (13) due to the difference in weight is measured by a differential transformer ( 16), the weight is automatically measured without stopping the object to be sorted (a).

The sorting unit (5) has a weight difference of 5 depending on the weight of the object to be sorted (a).
The grades are classified into stages, and each of them is automatically collected in five collecting tools (4). That is, the sorting unit (5)
A transfer conveyer (18) is provided for continuous transfer in succession to the transfer end of the measuring section (3), and five extruding tools (extruding the objects to be sorted laterally laterally on the lateral side of the transfer conveyor (18) ( 19) are arranged in parallel, and the guide chute (20) and each collecting tool (4) are arranged below the portions corresponding to the pushing tools (19). Then, based on the measurement result of the measuring unit (3), the push-out tool (1
9) Automatic collection tool (4) corresponding to the item to be sorted (a)
It is configured to be collected.

As shown in FIG. 1, the second transfer device (8) in the carry-out section (2) has an endless transfer belt (2) which is an example of a transfer member.
1) is wound around a pair of upper and lower pulleys (22) and (23), and locking protrusions (24) are attached to the outer peripheral surface of the conveyor belt (21) at a predetermined pitch to rotate the conveyor belt (21). Along with the movement, the objects to be sorted (a) are placed one by one on the locking projections (24) and conveyed. Then, as shown in FIG. 2, a through hole (25) through which the transported object can pass is provided in a region between the locking protrusions (24) other than the predetermined placement portion of the sorted object (a). A guide member (26) that is formed and extends from the start end of the conveyor belt (21) to an intermediate position is provided along the lower surface side, and passes through the through hole (25) from below the upper end of the guide member (26). A returning device (27) is provided for returning the dropped object (a) to the hopper (1).

In this way, at the end of conveyance, one item to be sorted can always be placed on each locking projection (24) and reliably delivered as a single unit.

It should be noted that reference numerals are added to the claims for convenience of comparison with the drawings, but the present invention is not limited to the structures of the accompanying drawings by the entry.
