(effect) Next, we will discuss the effect.

Before feeding the fruit 18 onto the supply roll 9, depending on the type of fruit 18, the distance between the terminal ends 43, 43 of the width belts 38, 38 is adjusted to the minimum distance by rotating the tongue buckle 54. Since the spring 56 is attached between the width belts 38 and 38, the pins 49 and 49
move within the elongated hole 51 and stop with the bottles 49 abutting the inner ends of the elongated hole 51, respectively.

Then, when the fruit 18 is placed on the supply roll 9 and the supply roll 9 is rotated by the motor, the fruit 18 flows out toward the flow plate 2, and is divided into approximately three equal parts by the flow plate 2, and then the fruit 18 is divided into three equal parts by the flow plate 2. Transfer between supply brush rolls 12.12.

Since the supply brush rolls 12 are all rotating to the left,
When there is excess fruit 18, it is moved to the left side and the falling part 1
Fall to 9. In this case, two chevron-shaped guide plates 13 are provided so that even fruits 18 that are not excessive are not guided to the falling part 19.

That is, the fruit 1 that collided with the steeply sloped surface 14 of the chevron-shaped guide plate 13
8 is stopped here because the slope of the steep slope surface 14 is steep. Excess fruit climbs over and falls into the falling part 19, and is returned to its original state by the conveyor 21. The fruit 18, which has been quantified by the supply brush roll 12 of the quantitative supply part 3, is supplied between the alignment brush rolls 22 of the alignment supply part 5. , are aligned. The guide plate 24 is made up of an alignment plate 22, and the upper surface of the gap 23 is covered with a guide plate 24 every other time, so that it is aligned in three rows, and the aligned items are transferred to the transfer part 6.

Since the transfer section 6 is formed by a pair of left and right transfer endless belts 33 and a bottom delivery endless belt 30, the fruit 18 flows between them. 35 is open, so it can be smoothly flowed in and taken over. Further, although the fruit 18 is transported by the endless delivery belt 30, since the outer peripheral surface of the endless delivery belt 30 is provided with protrusions 39, the fruit 18 does not slip. 1
It moves to the width belt 38.38 of the width width part 7 and flows out to the take-out part 8 from between the terminal ends 43.43. In this case, since the distance between the terminal ends 43 and 43 is adjusted by the tongue buckle 54, the left threaded rod 52, and the right threaded rod 53, even small fruits are brought closer to the center of the endless delivery belt 30. In this case, when a fruit 18 that is larger than the interval between the end sides 43 and 43 is sent, the fruit 18 is sent to the end side 43 against the elasticity of the spring 56.
．． Since it is sent out for 43 minutes, it does not damage the fruit 18.
