Abstract

PURPOSE:To align the stems of fruits along the clamping face of a conveyor, and clamp the stems in vertical state, by placing an apparatus for correting the transversal and longitudinal positions of the stem before the apparatus for clamping and transferring the fruit stem. CONSTITUTION:The fruit stem protruded below the fruit-supporting part 2 is shifted to the position coinciding with the clamping face of the apparatus 3 for clamping and transferring the fruit stem. The position coincides also with the moving orbit of the center of the supporting part 2 when viewed from the top. The shifted stem is clamped laterally with the apparatus 3, and the neck of the bag C of the fruit B is cut with the stem clamping device 6 and the neck cutting device 7. The fruit is transferred to the apparatus 8 for correcting the machine direction of the stem, and the stem is corrected to vertical position viewed from the side. The stem is clamped with the apparatus 3, and cut with the stem cutting device 4.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for transferring a harvested fruit with a bag and a stalk to a fruit receiving portion of a conveyor, and transferring the fruit stalk of the fruit from a through hole provided in the fruit receiving portion to the lower surface of the fruit receiving portion. During the transportation process, the fruit is transported by being placed in a state where it protrudes to the side, and during the transportation process, the fruit is transported by a pedestal clamping and conveying device and a pedestal cutting device, which are disposed on the lower side of the movement trajectory of the fruit receiver. This invention relates to an improvement in a fruit stem cutting device which cuts the fruit stem part.

The fruit stem cutting device targeted in the present invention is one of the above-mentioned fruit stem cutting devices, in which the fruit stem holding and conveying device cuts the fruit stem protruding from the through hole of the fruit receiver. In a plan view, the fruit is gripped from the left and right of the movement trajectory with a holding surface that is aligned with the movement trajectory of the center point of the through hole of the fruit receiving part, and in that state, the fruit is conveyed along the movement trajectory. It is a stalk cutting device.

The above-mentioned type of fruit stem cutting device has a structure in which the fruit stem is cut by the fruit stem cutting device while being held and conveyed by the fruit stem holding and conveying device. The length of the fruit stalk becomes irregular, and the cut of the fruit stalk [J] becomes an irregular shape with a diagonal shape.

The present invention solves the above-mentioned problem in the posture of the stem of the fruit that is placed on the fruit holder and protrudes from the lower side of the fruit, and the state and fruit when the fruit is placed on the fruit holder. Focusing on the fact that irregularities occur due to the shape of the fruit, which is caused by the fruit being held in an irregular posture by the fruit stem holding device, the appearance of the fruit stem held in this fruit holder was determined. The purpose is to have the fruit stem aligned with the clamping surface of the pedestal clamping and conveying device and perpendicular in side view, and to be held in that state by the pedestal clamping and conveying device. The device of the present invention for achieving this object includes a fruit receiving device of the conveyor, which is placed on the lower side of the conveyor's conveyance path in the fruit stalk cutting device described above, and before the fruit stalk holding and conveying device. A left-right direction in which the stem of a fruit, which moves protruding from the lower side of the fruit, is brought to a position aligned with the locus of movement of the center point of a hole provided in the fruit receiver so that the stem protrudes downward in plan view. The present invention is characterized in that it is provided with a stalk position correcting device, and a stalk position correcting device in the front-rear direction that corrects the stalk portion of the fruit straight forward in a side view.

Next, the function and effect will be explained. As mentioned above, the fruit stem cutting device according to the present invention has the fruit stem receiving part (2) of the conhair a.
) of the fruit B, which protrudes from the bottom side of the fruit receiving part (2), is held by the stem part holding and conveying device (3) disposed on the bottom side of the conveyor path of the conveyor a. , and when feeding the fruit stem from the left and right sides and feeding it to the fruit stem cutting device (4) for cutting, the fruit holder is held before the fruit stem is held by the fruit stem cutting device (3). The posture of the stalk protruding toward the lower surface of the portion (2) is controlled by a left and right stalk position correction device (
5), the through hole (22) of the fruit receiving part (2) is
1 to a position that is aligned with the moving trajectory Y of the center point, which is a position that coincides with the holding surface of the pedicel holding and conveying device (3), and further, the pedicel position correcting device (8) in the front and back direction is used to align the center point of the pedicel with the vertical position in side view. Since the posture is corrected and the corrected state of the stem is held by the stem holding and conveying device (3), the stem is held by the stem holding and conveying device (3). There were problems with the uneven cutting positions of the stems, which were caused by the stems moving when being held from the left and right, disturbing the holding condition, and being held in an inclined position, and the cutting position of the stems.
