Description

[Detailed Description of the Invention] This invention relates to a tray support device for a weight sorter in a fruit sorting facility or the like.

Conventionally, in a tray support device for a weight sorting machine that weighs and sorts fruits while transporting the tray with a chenette, etc., as shown in Fig. 1, a guide rail and a point of the weighing device are attached to one end of the tray. A pin that slides on the rail is protruded, and the other ends of the upper and lower link rods are rotatably supported near the protruding part of the pin on a supporting frame that is suspended from the transfer cheno. Therefore, when the guide of the pin of the saucer is released and the link rod is rotated downward around the pivot of the support frame to tilt the saucer and release the loaded fruit, the rotation range of each link rod is large. However, since the pin position is at one end of the saucer and is far from the center of gravity of the saucer, it has the disadvantage that a large load is applied to each link rod.

This invention takes the following technical measures to eliminate the above-mentioned drawbacks.

That is, a pin 5 that slides on a guide rail 2 and a point rail 4 of a weighing device 3 is installed in a protruding manner at the center and side of a tray 1 on which fruit can be placed, and a supporting frame 7 is held on a transfer cheno 6. The other ends of the left and right link rods 8, 8, which are rotatably supported on the upper part, are rotatably supported on both sides of the saucer 1 on the support frame 7 side from the pin 5 mounting position, and are rotatably supported on the lower part of the support frame 7. The other ends of the left and right link rods 10, 10, which are movably supported and whose intermediate portions can be bent about the pivot shaft 9, are placed below the pivot points of the link rods 8, 8 on the side of the support frame 7 from the pin 5 mounting position. A tray support device in a weight sorter is rotatably supported on a tray at a position.

In the illustrated example, reference numeral 11 indicates a holding member for the support frame 7 installed on the transfer chinos 6, 6, and a mounting portion 12 on the upper part of the support frame 7.
It is mated and held together.

The support frame 7 is composed of an upper support frame 13 that hangs shortly from the outermost side of the attachment part 12, and a lower support frame 14 that hangs long from the attachment part 12 inside the upper support frame 13. One end of the link rod 8 is rotatably supported by a shaft 15,
At the lower part of the lower support frame 14, one end of a link rod 10, which can be bent at its intermediate portion about a pivot shaft 9, is rotatably supported by a shaft 16.

A pin 5 is protruded from approximately the center side of the tray 1 and supports the tray 1 by sliding on a guide rail 2 disposed along the direction of the transfer chamber 6.

Reference numerals 17 and 18 denote support frames provided on the side of the tray 1 on the side of the support frame 7 from the protruding position of the pin 5 of the tray 1; The other end of the link rod 10 is rotatably connected to the lower end of the support frame 18 by a pivot shaft 20.

In addition, each support frame 13, 14, link rod 8, 10, support stem 1
7, 18, etc. are provided in pairs on each side of the saucer 1.

The spring 21 of the weighing device 3 is located in the missing part in the middle of the guide rail 2.
A point rail 4 is provided which is supported by the point rail 4, and the pin 5 of the saucer 1 on which the fruit with a weight exceeding the shell limit is mounted is mounted on the point rail 4.
When passing over the point rail 4, it resists the spring 21.
The pin 5 is lowered to guide the pin 5 to the inclined guide guide 22.

23 is a drawer conveyor for sorting fruits, and 24 is a stopper.

When fruits are appropriately loaded into the trays 1, 1, . 6, 6, and is pulled by the holding member 11 installed at 6, guided by the pin 5 by the guide rail 2, and transported in the direction of arrow A in the fruit loading attitude.

During this transfer, since the pin 5 is located approximately at the central side of the saucer 1, that is, near the center of gravity, and receives the weight of the fruit, an unreasonable load is placed on each link rod 8, 10 and each pivot point. It is possible to transfer the saucer 1 while maintaining its posture at a constant level without adding any pressure, and it is also possible to smoothly rotate each link tr] 8.10 for lowering the saucer 1 at the rear fruit sorting position. .

Through this transfer, the pin 5 of the tray 1 reaches the point rail 4 of the weighing device 3. At this time, if the weight of the fruit loaded on the tray 1 is smaller than the weight setting value of the spring 21 of the weighing device 3, the pin 5 of the tray 1 reaches the point rail 4 of the weighing device 3. By only slightly lowering the point rail 4, it is guided to the succeeding guide rail 2, and is further transferred in the direction of arrow A, and is sequentially sorted by a weighing device (not shown) at the rear that gradually reduces the setting value of the spring 21. be done.

In addition, if the weight of the fruit loaded on the tray 1 is larger than the weight setting value of the spring 21 of the weighing device 3, the point rail 4 is lowered against the spring 21, and the pin 5 of the tray 1 is lowered. The guide is then transferred to the inclined guide guide 22.

In response to the lowering of pin 5 of this saucer 1, each link rod 8.10
is rotated downward about the pivot shaft 15.16 to the support rod 13.14 to tilt the saucer 1.
Due to the inclination, the center of gravity of the saucer 1 is moved to the rear side in the tray transfer direction, and the link 10 is bent around the pivot shaft 9, and the saucer 1 is further rotated around the axis 9, making the saucer 1 larger and faster. The body is rotated into a prone position.

As described above, the present invention has a tray on which fruit can be loaded with a protruding pin that slides on the guide rail and the point rail of the weighing device approximately at the center and side, and a supporting frame that is held on the transfer ceno. The other ends of the left and right link rods that are rotatably supported on the upper part are rotatably supported on both sides of the saucer on the side of the support frame from the pin mounting position, and the other ends of the left and right link rods are rotatably supported on the lower part of the support frame. This is because the other ends of the left and right link rods, whose intermediate portions can be bent around the pivot shaft, are rotatably pivoted to the receivers located below the pivot points of the link rods, closer to the support frame than the pin mounting position. During the transfer of the saucer, the weight of the loaded fruit is supported by the pins, and the rotation of each link rod for the lowering of the saucer at the rear fruit sorting position is avoided. In addition, the link rod is short, and the lower link rod bends around the pivot shaft in the middle of the link to quickly and greatly lower the tray. The sorted fruits can be released quickly.
