Description

[Detailed Description of the Invention] This invention involves placing objects to be sorted, such as fruits and vegetables, on a tray, passing the tray over a weighing device while moving the tray, and classifying them by weight based on this measurement. This relates to an improvement of the fruit tray support device of a weight-type fruit sorting machine that overturns the tray and transfers the sorted materials, which prevents damage to the sorted materials during transfer and also allows the fruit sorter to have a compact structure. The purpose is to

For this reason, the following technical measures were taken.

That is, the endless belts 19 are arranged approximately parallel to each other at appropriate intervals.
In between, the tray 1 is vertically movably supported at vertical positions;
In addition, upper and lower front-back links 2 and 3 are provided which are arranged at appropriate intervals left and right along the moving direction of the endless band 19 and move in the same direction in relation to the movement of the endless band 19. ,
A fruit tray support device for a weight-type fruit sorting machine is constructed by projecting a sliding pin 5 to the side of the grains from one of the upper and lower front-rear links 2 and 3 to make sliding contact with the weighing device A.

The present invention achieves the following technical effects through the above-described configuration.

That is, when discharging the objects to be sorted, the tray 1 moves downward in conjunction with the downward movements of the upper and lower front-back links 2 and 3, and then the tray 1 falls over, reducing the impact on the objects to be sorted. Damage to the product can be prevented.

Furthermore, during this discharge, since the links 2 and 3 are arranged at appropriate intervals left and right along the moving direction of the endless belt 19, the amount of uneven gutter to the endless belt 19 is reduced. As a result, the inorganic band 19 can be moved smoothly. Also, endless belt 1
Since the tray 1 and the links 2 and 3 are installed between the trays 1 and 9, the operator can approach the endless band 19 side, making it easy to feed the objects to be sorted to the tray 1 and work safely. Can be done. Hereinafter, one embodiment of the present invention will be specifically described based on the drawings. The upper and lower longitudinal links 2 and 3 are formed in the shape of a rectangular box frame in plan, and the front end of the upper longitudinal link 2 is attached to the projection 7a of the mounting plate 7 on both left and right sides of the upper longitudinal link 2. It is pivotally mounted with horizontal pins 8 extending between the sides so that it can be placed up and down.

The front end of the lower longitudinal link 3 is attached to the protrusion 7a of the mounting plate with an intermediate link 9 formed in the shape of a surrounding frame interposed therebetween.
1, it is pivotally connected so as to be vertically movable. The fruit tray 1 is attached to the rear of the upper and lower front-rear links 2 and 3, and has a fruit tray 12 in the center of which is recessed in the shape of a mortar, and extends downward at the bottom. The protrusion 13 is integrally formed.

This protrusion 13 includes upper and lower front-rear links 2,
3 is pivotally connected to the inside of the surrounding frame by horizontal and lateral pins 14 and 15, so that the fruit tray 1 is supported by the upper and lower front-rear links 2 and 3.

In addition, the above-mentioned horizontal and lateral pins 10, 11, 14, 15
Each of the links 2, 3, and 9 is inserted between the left and right sides of the links 2, 3, and 9.

Further, in the case where the fruit receiving surface 12 of the fruit receiving tray 1 is provided with, for example, horizontal and lateral pins 14 and 15 inserted into the inside of the receiving tray 1, the insertion of the pins 14 can be easily visually checked. The concave long groove portion 16 may be formed so that the process can be performed while checking.

The sliding pin 5 is provided on the upper longitudinal link 2, and is installed and fixed behind the horizontal and lateral pins 14 and 15 in the moving direction and between the left and right sides of the upper longitudinal link 2. This end is formed so as to be able to protrude laterally and come into sliding contact with the rail B.

Further, this sliding pin 5 is configured to be able to protrude from either the left or right side of the upper front-rear link 2, and can be selected depending on the side where the rail B is present, which is very convenient.

The aforementioned mounting plates 7 are attached at appropriate intervals to an endless band 19 that guides and rotates on a guide body 17, and is pulled and moved in the direction of arrow A by rotation of the endless band 19.

A is a conventionally known weighing device having a vertically movable rail C and a fixed rail D on the upper side.

In the configuration of the above example, due to the rotation of the endless band 19, the attachment member 7, the upper and lower front-back links 2 and 3, and the fruit tray 1 are pulled in the direction of arrow A, and the Numakin pin 5 is pulled toward the rail B. The weight of the fruit tray 1 is supported by sliding on the top.

When this sliding pin 5 reaches the rail C of the weighing device A, if this weight exceeds the weighing limit, the rail C moves downward, and the sliding pin 5 descends along the rail D. Therefore, when the upper and lower front-rear links 2 and 3 move downward around the pins 8, 10, and 11 and move the fruit tray 1 downward together, the fruit tray 1 moves the pins 14 and 15 downward. The fruits, etc. fall downward from the center and are discharged from the fruit tray 1. After this,
When the sliding pin 5 continues to move along the seal, it returns to its original horizontal position, and the upper and lower longitudinal links 2 and 3 and the fruit tray 1 move upward together and return to their original horizontal position. It will be done.

In such a series of sorting operations, the vibrations generated when the sliding pin 5 slides on the rail B are transmitted to the upper longitudinal link 2, which absorbs most of the vibrations. Since the vibration is transmitted only indirectly and not directly, and because of this, the fruit etc. are less likely to be transferred on the fruit tray 1, so the fruit tray 1 will not vibrate up and down. As a result, fruits etc. can be weighed accurately on the weighing device A.

In addition, upper and lower front-rear links 2 and 3, and intermediate link 9
are formed in a frame shape with wide intervals, and the horizontal pins 8, 10, 11, 14, 15 and the sliding pin 5 extend between the left and right sides of each of these links 2, 3, 9. Each pin 8, 10, 11, 14, 1
5 and 5 can serve as reinforcing materials for each link, and even if the links are made thin and light, these link structures will remain strong and stable without distortion, and in addition, they can move up and down smoothly, and each drive It is easy to apply an even load to the parts, and the fruit etc. tray 1
It is possible to accurately measure the weight received from the
