Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is suitable for carrying out so-called long vegetables such as carrots, radishes, and cucumbers one by one and sorting them into grades. This invention relates to an unloading device that allows automatic unloading.

[Conventional technology]

Conventionally, the above-mentioned unloading work was generally performed manually.

[Problem to be solved by the invention]

In the manual process described above, it is possible to reliably transport one item at a time, so the sorting and sorting in the later process has the advantage of making it easier to automate the work, but as the amount of processing increases, the labor burden on the workers increases. This has serious disadvantages, and it has been desired to automate such unloading work.

Therefore, a structure as shown in FIG. 6, for example, was devised to automatically carry out the above-mentioned unloading work. That is, at the bottom of the hopper (1), the first transport conveyor (40) for horizontally transporting the objects is disposed, and the first transport conveyor (40)
The protrusion (41) locks the conveyed object that falls from the terminal end of 0).
It is configured to be placed and conveyed diagonally upward on a second conveyor (42).

However, in the above improved structure, the first conveyor (
Since the structure is such that the weight of the objects in the hopper (1) is forcibly conveyed onto the conveyance surface of the hopper (1), there is a high risk that the objects will be damaged during transportation. In addition, there was also the drawback that two conveyors were required, making the structure complicated.

SUMMARY OF THE INVENTION An object of the present invention is to provide an unloading device that can automatically unload long vegetables with a simple structure while minimizing damage to the transported items.

[Means to solve the problem]

The present invention is characterized in that it includes a hopper that stores a large number of items to be carried out, and a conveyance device with a locking protrusion that places and conveys objects to be conveyed diagonally upward from the lower part of the hopper. A notch is formed to allow entry into the diagonal conveyance area of the conveyance device, and a cutout wider than the width of the diagonal conveyance area is formed inside the hopper along the upper side of the diagonal conveyance area. This is because a guide plate is provided.

[For production]

The conveyance device sequentially places objects to be conveyed from the bottom of the hopper and conveys them. At this time, since the diagonal conveyance area of the conveyance device is inward of the hopper, the objects to be conveyed are placed on each of the locking protrusions during the conveyance, and furthermore, Since a guide plate is provided above the hopper, the entire weight of the stored material in the hopper is not applied to the transported object during transport.

〔Effect of the invention〕

As a result, it is possible to carry out single-unit unloading with less damage to the transported items and with less omissions, using only one transport device, and automatic unloading is possible with a simple structure. I was able to do it.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIG. 5 shows a direct motion sorting device that automatically sorts long vegetables such as carrots into paper cans by weight sorting. This sorting device includes a hopper (1) that stores a large number of objects (a), and carries out the objects (a) to be sorted diagonally upward one by one at a predetermined pitch from the bottom of the hopper (1). An unloading section (2), a measuring section (3) that is connected to the conveying end of the unloading section (2) and automatically measures the weight of each object to be sorted (a) while being conveyed horizontally, and the measuring section (3). It consists of a sorting section (5) that automatically sorts and collects into a plurality of collection tools (4) based on the measurement results in >.

As shown in FIG.
At the bottom of the conveyor belt (12) for placing and conveying the object (a), there is a weighing platform (13) that is displaced downward by the weight of the object (a) to be sorted.
) is provided so as to be biased back to a predetermined position by a balance spring (14) and a damper mechanism (15), and the difference in the amount of downward displacement of the weighing platform (13) due to the difference in weight is compensated for by the differential transformer (
16), so that the weight of the objects to be sorted can be automatically measured without stopping them.

The sorting section (5) is configured to separate
They are classified into stages and automatically collected into five collecting tools (4). In other words, the sorting section (5)
A conveyor (18) that is connected to the conveyance terminal end of the measuring section (3) and continuously conveys the conveyor (18) is provided, and this conveyor (
18) Push out the object to be sorted (a) laterally to the side part of 5
A number of extrusion tools (19) are arranged in parallel, and a guide chute (20
) and each collection tool (4) are provided. Based on the measurement result of the measuring section (3), a pushing tool (19) corresponding to grading automatically collects the object to be sorted (a) into a corresponding collecting tool (4). .

The conveyance section (2) includes a pair of upper and lower pulleys (21).

(22), a conveyor belt (23) is wound around the endless conveyor belt (23), and a number of locking protrusions (24) are provided at a predetermined pitch on the outer periphery of the conveyor belt (23).
The diagonal conveying area (L) in this conveying device (25) is arranged so as to enter inside the hopper (1) through a notch (26) formed in the hopper (1). .

As shown in FIGS. 1 and 2, the lower part of the hopper (1) is tapered and has an opening (27
), and the edge (27a) of this opening (27) on the side where the transport device (25) is disposed is provided at a higher position than the opposite edge (27b), and the above-mentioned cutout is formed in a continuous manner from this opening (27). A notch (26) is formed. The opening (27) faces the starting end of the conveying device (25). And hopper (
1) Inwardly, the diagonal conveyance area (
A guide plate (28) wider than the width of the diagonal conveyance area (L) is provided along the upper part of the diagonal conveyance area (L).
A diagonal conveyed object supply opening (30) is formed between the lower edge (28a) of 8> and the opposing side wall (29), and the conveyed object (a) spilling out from this supply opening (30>) are sequentially placed on the locking protrusions (24) of the conveyance device (25) and conveyed diagonally upward.At this time, during the diagonal conveyance, the weight of the stored articles is received by the guide plate (28>). The guide plate (28) is height-adjustable and slidable by means of a screw adjustment mechanism (43), so that it can be changed depending on the type of crop. It is.

In addition, when a plurality of objects to be conveyed are forcefully placed on the locking protrusion (24) and protrude laterally outward, the guide plate (28) locks the protruding objects and locks the hopper. A dispensing tool (32) is provided in (1) for dropping and returning.

Further, as shown in FIG. 2, the locking protrusion (24) on the conveying device (25) is formed into a comb shape, and the hopper (1)
The opening edge of the opening is formed into a comb shape in which the locking protrusions (24) fit together to prevent crops from digging into the opening.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
