Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a shape sorting device for sorting the shape of spherical objects such as tomatoes and apples, or damaged long objects such as cucumbers.

[Conventional technology]

2. Description of the Related Art Conventional shape sorting devices include those configured to detect objects to be sorted from the lateral direction and those configured to detect objects from above and below.

[Problem that the invention seeks to solve]

However, in the above configuration, when sorting objects,
A sorting device must be prepared according to the material to be sorted.

For this reason, if a sorting device equipped with each detection device is installed in a sorting place, a large installation space will be required, which will require a large sorting house, and the cost will also increase.

[Means to solve the problem]

The purpose of this invention is to solve such technical problems. To this end, we took the following technical measures.

In other words, a conveyor (2) on which the objects to be sorted (1) are placed and transferred.
During the transfer, a discrimination detection device (3) detects the height of the object to be sorted from the mounting surface, and the object to be sorted (1) is transferred to the conveyor (2).
) and a horizontal inspection hanging device (4) that can detect objects to be sorted (1) from the lateral direction with respect to the direction of conveyance (2), and a vertical detection device that can detect objects to be sorted (1) from below in the direction of conveyance (2). Device (5
) is provided 1, and when the discrimination detection device (3) detects the height of the object to be sorted (1) as [high 1], both detection devices (4) and (5) are activated, and the height of the object to be sorted (1) is set to 1 low. In order to activate only the vertical detection device (5) when the detection occurs, the discrimination detection device (3), the horizontal detection device (4), and the lower horizontal suspension device (5) are configured in a related manner.

[Effect]

The discrimination detection device (3) detects the height of the objects to be sorted transferred by the conveyor (2), and when it is detected as "high", it is connected to the side detection device (4) and the lower detection device. By activating both the detection devices (5), it becomes possible to detect the height and width of spherical objects and thick objects.

Furthermore, when it is detected as "low", the low detection device (5) becomes capable of detection.

〔effect〕

Therefore, in the case of spherical or thick objects such as tomatoes or apples, the height and width directions can be detected 1-13, improving the sorting accuracy, and even long objects such as cucumbers can be sorted by shape. . Moreover, since both of these sorting functions can be carried out by one sorting device, it is possible to sort thick materials and fine materials, so that the sorting place can be configured compactly.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.The conveyor (2) includes a pair of left and right endless bands (7) which are rotatably stretched, and a base part of which is rotatably attached to the endless bands. It is composed of a large number of carriers (6) which are pivotally supported and whose tips are supported by guide rails (not shown) and arranged at predetermined intervals. In this example, the objects to be sorted (], ) are placed on each carrier (
Although the configuration is such that one object is placed on each object (6), multiple objects (6) can be placed on each object.
Alternatively, one object to be sorted may be placed on the tray.

The discrimination detection device (3) is an optical sensor consisting of a light emitting element and a light receiving element, and is configured as a unit and is connected to the conveyor (2).
), the gate-shaped casing (8) is exposed in several cases when viewed from the front (viewed from the direction of transport). The sensor unit (3) is provided in the casing (8) so that it can be moved downwardly and fixed by an adjustment tool (9).

The lateral detection device (4) is composed of a light emitting element 01) mounted on the leg 00 of the casing (8) and a light receiving element 04 mounted on the leg O3, and the light emitting element 011 and the light receiving element 031 is "- multiple pieces downward (5 pieces in the example)
are provided and are provided relative to each other. It should be noted that the element located at the lowest end among the respective elements is positioned slightly on two sides of the body (6).

” The second lower detection device (5) is the lower frame θ of the casing (8).
4) The light-emitting element 0 (to) placed in the section and the two frames 00
The pixel elements θ (I7) are arranged at predetermined intervals in the lateral direction, that is, in the direction orthogonal to the moving direction of the conveyor (2). In the embodiment, 12 elements are provided, and each element is provided opposite to each other. Note that among the elements, the elements located at both left and right ends are arranged to be located at both ends of the carrier (6).

The lateral detection device (4) and the vertical detection device (5) are located closer to the transfer direction of the conveyor (2) than the discrimination detection device (3). Same view
It is located on the line.

To explain the block circuit shown in Fig. 4, 08) is a comparison calculation circuit, which is connected to the discrimination detection device (3), the multiplexer 09, the memory wire, the interface (goods), and the drive circuit (a). There is. The multiplexer 09 is connected to the lateral detection device (4), the vertical detection device (5), and the interface Cυ. The drive circuit (a) is configured to energize a solenoid (not shown) that causes the carrier (6) to fall over at a predetermined classification position. The function of the comparison calculation circuit 08) is to receive "H" (high) and rLJ (low) signals from the discrimination detection device (3), and to detect rHJO.
When the rL
During JO, only the vertical detection device (5) is activated. Further, the magnitude is determined by comparing and calculating the input value inputted from each detection device (41(5) via the interface Qυ and the set value stored in advance in the memory (A)). Then, the solenoid corresponding to the classification position is energized via the drive circuit (a), the carrier (6) is overturned, and the material to be sorted is discharged to a predetermined position.

To explain the flowchart of FIG. 5, first, the memory (a) is read and then the input signal of the discrimination detection device (3) is input. Then, if this input signal is rHJ or
If the result is “H”, multiplexer 0 is selected.
In step 9, the input values of the side detection device (4) and the top and bottom detection device (5) are taken in, and the comparison calculation circuit θ8) calculates the height and width of the object to be sorted. ) is discharged to a predetermined position.

In addition, at the time of rLJ, only the input value of the up/down detection device (5) is taken into the comparison calculation circuit Q8), where it is arithmetic processed, the size is determined, and it is discharged to a predetermined classification position. .

In the configuration shown in E-H, the objects to be sorted placed on the carrier (6) also move in the same direction as the conveyor (2) moves, but when passing through the discrimination and detection device (3),
This detection device (3) distinguishes between rHJ and rLJ.

Now, if the object to be sorted (1) is a spherical object such as a tomato or an apple, the object to be sorted becomes rHJ and activates the horizontal detection device (4) and the vertical detection device (5), so that the object to be sorted is The height is detected by the lateral detection device (4) at the part facing this detection device (,il (5)), and the height is detected by the vertical detection device (4).
5), the width perpendicular to the transport direction is detected.

Therefore, since the classification position is determined by the comparison calculation circuit 08 based on the detection result of the rain detection device (41(5)), the classification accuracy can be improved.

Next, if it is a paralyzed plant (B) like a cucumber,
Since it becomes "L" and only the lower detection device (5) is activated, the length of the object to be sorted is detected by this detection device (5), and then the length is detected by the comparison calculation circuit 08). After the classification is determined, it is discharged at a predetermined classification position.

In this way, since the length of the cucumber can be detected even if both ends of the cucumber are warped, classification accuracy can be improved. Furthermore, even if spherical objects such as apples and tomatoes and τ-long objects such as cucumbers are brought in at the same time, they can be sorted and sorted on the same conveyor by simply switching the detection device. It's Kade.
In this way, if automatic detection is performed using the discrimination and detection device (3), it is possible to perform the spherical object sorting operation and the long object sorting operation at the same time.

In this embodiment, the detection device was automatically switched, but it goes without saying that the detection device may be switched manually if the spherical object sorting operation and the long object sorting operation are to be performed separately.
