Abstract

PURPOSE:To securely carry out sorting of fruits without damaging them by installing receiving boards, which project out between a pair of chains being opposite to each other and which are inclinable with each opposite end side directed downward, in alignment in the endless direction. CONSTITUTION:When chains 1, 2 move on rails 8, a fruit 5 placed on the top surfaces of receiving boards 3, 4, which are installed between the chains 1, 3 being opposite to each other, is transferred and, as it comes above a draw-out conveyor 22, a cam 18 is rotated by a certain angle due to the action of a solenoid 16, an engaging pawl 14 is disengaged from an engaging pin 11, causing the receiving board 3 to be inclined with its end side opposite to the receiving board 4 directed downward. As for the receiving board 4, its end side opposite to the receiving board 3 is lowered with a fulcrum 20 as the center of inclination, due to the inclination of the fruits, which, in turn, falls on the draw-out conveyor 22.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyor for transporting fruits and the like, and is used in fruit sorting machines and the like. The fruit conveyor of a transfer sorting machine that sorts fruits, etc. by placing them thereon is generally configured so that the fruit tray on which the fruits are placed is raised in the direction of transfer and tilted backwards to allow the fruits to fall downward. However, the interval between the transfers of the trays was determined by the interval between the transfers of the fruit, and it was not possible to reduce the transfer interval even for small fruits. In addition, since the fruit falls while rolling on the tilted tray surface, it may be damaged by colliding with other fruits or the side wall of the fruit tray. Furthermore, it was difficult to sort out long fruits such as cucumbers and nanu and round fruits such as apples and tomatoes.

For this reason, the present invention has taken the following technical measures. In other words, a pair of chains 7 (1) and (2) are stretched endlessly at a constant interval and transported synchronously, and each of these chains protrudes oppositely between them, and Receiving plates (3) and (4) which can be tilted downward are arranged in series in the endless direction, and at least one of the receiving plates (3) has this receiving plate (
3) (4) The conveyor for fruits, etc. is provided with a tilting mechanism (6) for tilting the fruit (5) placed on top to be transported so as to fall downward.

With this configuration, the present invention has the following technical effects. That is, when the fruit (5) is placed on the receiving plates (3) and (4) and transferred, and the tilting mechanism (6) is applied due to the weighing of the weighing device, the receiving plates on both opposing sides ( 3
) and (4) at the same time, and the fruit is placed on the receiving plate (3).
The opposing ends of the receiving plates (3) and (4) descend at the same time, sinking into the V-shaped groove that gradually deepens, and fall from the wide gap between the receiving plates (3) and (4), so there is little head difference. In addition, since it is less susceptible to rolling effects, there is less risk of impact from falling and damage from transfer.

In addition, when using a device that transports an elongated fruit (5) by placing it on the receiving plate (3) and dropping it downward, the tilting mechanism of only one receiving plate (3) should be operated. , or move one of the receiving plates (3) and (4) faster and the other slower.
If the structure is tilted, one end of the elongated fruit (5) settles downward first, and the other end arrives after absorbing the weight of the fruit, so that shocks and transfers can be reduced. Furthermore, the receiving plate (3
) (4) are subdivided and arranged in an endless direction, so the fruit (5) can be placed at closer intervals in the endless direction, increasing efficiency. Furthermore, if the tilting mechanism (6) is used properly as described above, round fruits (5
) and elongated fruit (5), which also has transfer value.

Next, a diagram example will be explained. Frames (7) (7) Rails (8) (8) protruding inward from the frame (8) are provided with endlessly stretched chains 7 (1) and (2) placed on them,
- A receiving plate (
3) is rotatably supported on the fulcrum αO provided on the leg (9) attached to the chain 7(1), and the locking pin (■υ provided on the receiving plate (3) and the leg (9) A locking pawl Q4) supported by another fulcrum Q2 provided above and resiliently biased downward by a spring 03 engages to lock the receiving plate (3). The anti-engaging end aO of the locking pawl 04) is provided so as to approach and look below the cam θ which fixes the shaft (17) to the rotary solenoid α0 provided on the frame (7). In addition, the other check 7 (2) has a rotatable receiving plate (4) supported on a fulcrum (A) provided on a leg rail attached to the check 7 (2). It is provided opposite to the plate (3) in the - row. Note that the receiving plate (3) is supported by the leg 00 so as to maintain a horizontal posture due to its own weight. Furthermore, below the fruit conveyor 〇1) there is a drawer conveyor (5) for receiving the fruit (5).
A) is provided to transfer the fruit to the side of the fruit conveyor Cυ. Fruit (5) is an example of cucumber.

When the power of the motor rotates Naen (1) (2) and moves Ray/I/(8) (8) J2, it is installed opposite to said Ches 7 (1) and (2). The fruit (5) placed on the upper surfaces of the receiving plates (3) and (4) is transferred, and when the fruit (5) comes to the side of another larger drawer conveyor (A), it is placed on the frame (7). Current flows through the rotary solenoid 0 attached to the shaft (171) due to the force of the electromagnet. The anti-engaging end Q of the locking claw (14) that engages with the locking pin 0υ of the plate (3)
When G is pressed, the engagement between the locking pawl (14) and the locking pin 01) is disengaged, so the receiving plate (3) is turned downward with the end opposite to the receiving plate (4) centered around the fulcrum aI. Tilt the receiving plate (
3) (4) The fruit (5) sitting on top loses its support on the receiving plate (3) side and tilts downward with this side first. At this time, the opposite end of the receiving plate (4) to the receiving plate (3) is pushed down by the inclination of the fruit (5), so the opposite end side is tilted downward using the fulcrum as the center of tilting. The fruit (5) slides down on the inclined catch plate (4). One end of the fruit (5) that landed on the drawer conveyor (2) first absorbs the falling impact, and then the whole fruit lies along the drawer conveyor, so the impact is small. For example, elongated fruits such as cucumbers are placed on the side. It has the advantage that warts are difficult to remove.
