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, single items can be carried out reliably, so that the sorting work in the subsequent process can be carried out with high precision and
Although this process can be carried out smoothly, when the amount of processing increases, there is a problem in that the labor burden on the workers increases, so automation of such carrying out work has been desired.

SUMMARY OF THE INVENTION An object of the present invention is to provide a carrying-out device for sorting long vegetables, which has a relatively simple structure and is capable of automatically carrying out single-piece vegetables reliably.

[Means to solve the problem]

A feature of the present invention is that a first conveying device for placing and conveying objects to be conveyed is installed at the inner lower end of a hopper that stores a large number of objects to be conveyed.
The width of the loading surface is set to be shorter than the length of the transported object in the longitudinal direction, and the transported objects carried out from the terminal end of the first transporting device are successively scooped up and placed diagonally upward. A second conveying device with a locking protrusion for conveying is provided.

[For production]

The objects stored in the hopper are loaded and transported by the first transport device, but at this time, since the width of the mounting surface is short, the objects are placed at the side edges of the mounting surface during transportation. The portion protruding outward from the edge contacts the outer object and is conveyed while changing its posture so that its longitudinal direction substantially follows the conveyance direction, and is conveyed to the second conveyance device. At the starting end of the second conveying device, the object to be conveyed is fed in a direction facing the path, so that the respective locking protrusions ensure reliable loading and conveyance without any leakage.

〔Effect of the invention〕

As a result, according to the present invention, it has become possible to provide a device that can reliably and automatically carry out each unit.

〔Example〕

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

FIG. 6 shows an automatic 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 conveyance terminal 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 the waste into a plurality of collection tools (4) based on the measurement results.

As shown in FIG.
At the bottom of the conveyor belt (12) on which the material to be sorted (a) is placed and transported, there is a weighing platform (13) that is displaced downward by the weight of the material to be sorted (a).
The balance spring (14) and the damper mechanism (15) are used to bias the weighing platform (13) back to a predetermined position, and the differential transformer (1
6), so that the weight of the object to be sorted (a) can be automatically measured without stopping it.

The sorting section (5) is configured to separate
They are classified into stages and automatically collected into five collection tools (4). In other words, the sorting section (5)
A transport conveyor (18) is provided at the end of the transport of the measuring section (3) for continuous transport, and five pushing tools ( 19) are arranged in parallel, and each extruder (
A guide chute (20) and each recovery tool (4) are arranged below the location corresponding to point 19). Then, based on the measurement results of the measurement unit (3), the push-out tool (19) corresponding to the grading automatically moves the object to be sorted to the corresponding collection tool (
4> It is configured to be pushed out and collected by falling.

Next, the structure of the unloading section (2) will be explained. As shown in Figures 1 to 3, the hopper (1) has left and right side walls (
21), the lower part of the hopper (21) is inclined in the shape of a gutter so that the stored material is guided to fall to the center of the lower end, and the transported material is guided along the opening (22) formed in the center of the lower end of the hopper (1). A first conveying device (23) is provided for placing and conveying. This first conveyance device (23) includes a pair of pulleys (24),
(25) An endless rotating belt (26) is wound around the belt (26), and a large number of conveying protrusions (27) are formed at a predetermined pitch on the outer periphery of the belt (26). ,
The outer peripheral mounting surface (27a) of the protrusion (27) is the left and right side walls (21).

(21) It has an arcuate shape that extends to the lower edge of the road surface. Further, this arcuate surface is provided in an arc having substantially the same shape as the outer periphery of the object to be transported. Moreover, the mounting surface (
The width (L) of 27a) is formed to be shorter than the length of the object to be transported in the longitudinal direction.

Further, at the inner upper position of the hopper (1), there is a first conveying device (
A plurality of rows of rollers (28) that freely rotate around the axis in the same direction as the arrangement direction of rollers (23) are arranged in parallel.

In other words, each roller (28) is fitted freely around the support shaft (29) fixed to the hopper (1), and the gap between each roller (28) is shorter than the length of the conveyed object in the longitudinal direction. It is structured like this. A chevron-shaped inclined guide plate (30) is placed above the first transport device (23).
) and is fixedly attached to the hopper (1). Edge of inclined guide plate (30) and hopper (1)
The distance between the sloped surface and the lower end opening (22) is the width of the lower end opening (22) and the distance between the paths.

A second conveying device (31) is provided which sequentially scoops up the objects to be conveyed, which are carried out from the conveying terminal end of the first conveying device (23), and places and conveys them diagonally upward.This second conveying device (23) 31) is a pair of upper and lower pulleys (32), (3
3), and a number of locking protrusions (35) for loading and conveying are formed on the outer peripheral surface of the belt (34) at a predetermined pitch. be.

The second conveyance device (31) is configured to convey in a direction perpendicular to the conveyance direction of the first conveyance device (23), and each locking protrusion (35) has a longitudinal direction that is perpendicular to the conveyance direction. Place it in the same position.

With the above configuration, the object to be transported on the first transport device (23) is stably placed on the protrusion (27) and transported with the longitudinal direction along the transport direction, and the object is transported by the second transport device (23). (3
1) The delivery to 1> is always carried out smoothly and reliably in a constant posture. Furthermore, the inclined guide plate (30) can prevent the weight of the stored items above from being applied to the items being transported, thereby suppressing damage.

[Another example]

The placement surface of the first conveyance device (23) may be configured to have a flat shape and a width narrower than the longitudinal direction of the conveyed object instead of having an arc shape.

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.
