At the heads of the lifting members 5, the nozzles 41 to jet compressed air upward at the outer peripheral parts of the heads and the suction ports 45a to suck the fruits B at the inner positions of the nozzles 41 are equipped. Consequently, fruits even with small weight are removed from them smoothly and safely.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a conveyor with a fruit receiving part for supporting the harvested fruit with a bag and a stalk in a state in which the fruit stalk protrudes downward, and the fruit receiving part A fruit stalk cutting device is provided on the lower side of the movement trajectory in which the fruit is supported and moves, and is equipped with a fruit stalk cutting device for cutting the fruit stalk protruding downward from the fruit receiver. Related to improvements in bag removal equipment.

In this conventional fruit stalk removal bag removal device, the mouth of the bag is cut off, and the fruit that is being transported is lifted from the fruit receiver and the mouth of the cut bag is removed. There is a device that removes the bags by blowing out pressure air from the bag, but when the lifting member is lifted, the pressure air nozzle remains in a fixed position, so it lifts the fruits that are being transferred. and the distance between the mouth of the bag and the nozzle is large,
The pressure air that is ejected may not be blown into the bag, and depending on the type of fruit, the pressure may cause the fruit to lift up from the lifting member and cause the opening of the bag to open incompletely. In many cases, the ejected pressurized air is not reliably blown into the bag, and as a result, the bag removal action is not completely performed.

The present invention was made in order to solve the problems of the prior art, and it is possible to smoothly and reliably remove the bag regardless of the type of fruit or the weight of the fruit. It is an object of the present invention to provide a novel fruit stalk cutting and bag removal device having a simple structure.

Hereinafter, the present invention will be explained in detail according to embodiments illustrating the present invention. I will clarify.

Its outer surface is in sliding contact with the outer surface of the connecting flange (46).

As shown in FIGS. 3 and 4, the nozzle (41) that opens on the outer periphery of the head of the push-up arm 6S is cut by the above-mentioned stem cutting device (3), and the mouth of the bag C is cut. The part C is opened and exposed on the lower surface side of the fruit receiving part (2) and is arranged so as to face the position directly below the movement trajectory of the opening mouth part C of the moving fruit B, and on the other hand, A suction port (45a) opened in the end face of the push-up part (54) is arranged so as to face a position directly below the entanglement of the movement locus of the karms of the fruit B.

S is a switch, and the connection flanges (4) and (46) on the side that move together with the push-up arm (55) slide into contact with the fixed side connection flanges (44) and (47), respectively, and connect the air supply pipe (401). It operates at the timing when the and the pressure air jetting pipe (49) communicate with each other and the suction pipe (451 and (48)) communicate with each other.

In FIG. 1 again, (5) indicates the pressure air blowing device (4).

b) so that it protrudes toward the fruit receiving part (2) against the urging force of the spring field, and is placed on the fruit receiving part (2) with the push-up part (54) at the outer end. The stem part of the fruit B is pushed up, so that the fruit B is slightly raised from the fruit receiving part (2) as shown in the center of FIGS. 3 and 4.

In addition, a recess (54a) is formed on the upper surface side of the push-up part (54) to receive a short cut fruit stem.

(6) is the upper surface side of the movement trajectory of the fruit receiving part (2) of the conveyor a, and as shown in FIG. Wind power / <-,
The pressure wind blown from the nozzle (41) of the pressure air blowing device (4) and the bags C peeled from the fruit B and blown up by the pressure wind are guided to one side of the right and left sides of the conveyance process of the conveyor a. It is formed by slanting and curving in the negative side direction. In this embodiment, the induced force t<-(6) is determined by the fact that the holder for placing the fruit B on the fruit holder (2) is formed by two parallel seats (2a) on the left and right. ,Also,
A pressurized air blowing device (4) disposed below the movement trajectory of the fruit receiving portion (2) is connected to the two seats (2a) and (2a).
), so that a vertical line passing through the center of the left and right sides of the fruit holder (2) is symmetrically placed on the top side of the fruit holder (2). Two sets of shafts are installed so as to be symmetrical to the left and right, and the guiding direction of each guided force l<-(6) is reversed on the left and right sides.

Next, to explain the function and effect, the fruit stalk cutting and bag removal device according to the present invention has nozzles (41) (4υ) for blowing pressure air using a pressure air blowing device (4) for bag removal. It is provided integrally with a push-up arm (lifting member) 65) that lifts the bagged fruit B from the fruit receiving part (2) while transporting the bagged fruit B in which the mouth part C of the bag C is cut to form a pressure air inlet. At the same time, since a suction port for sucking the lifted fruit B downward is provided inside the nozzle (41), (40...), the fruit B does not float up from the push-up part, and the pressure air is directed to the nozzle (41). As a result, even fruits B having a small weight can be reliably guided to the inlet at the opening C of the bag C, and the bag removal action can be carried out smoothly and completely.
