DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an apparatus for automatically arranging and packing flat fruits such as classified persimmons and the like, and particularly to an apparatus for uniformly arranging fruits without clogging.

[0002]

2. Description of the Related Art In a conventional fruit boxing machine, fruits that have been classified and conveyed by a belt conveyor or the like are supplied to an alignment conveyor having a predetermined frame to align the fruits, and the aligned fruits are suctioned by a suction unit. Is to be packed in a box.

[0003]

However, the above-mentioned conventional box packing machine cannot supply fruits uniformly in each frame of the alignment conveyor, and the boundary between the belt conveyor and the alignment conveyor cannot be used. The fruits were easily clogged and the fruits could not be arranged smoothly. SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus in which the above-mentioned drawbacks are eliminated and fruits are supplied uniformly and without damage in each frame without clogging.

[0004]

The present invention employs the following technical means to solve such technical problems. That is, the fruit feeding means and the fruit alignment means are connected by the fruit supply amount control means, and the fruit supply amount control means implants a large number of fiber hair-like projections on the plate surface and vibrates the fiber hair-like projections. And a fruit re-supplying means for conveying the fruit overflowing from the fruit supply amount adjustment control means in a direction opposite to the fruit conveying means. It is a device for adjusting the fruit supply of the machine.

[0005]

The fruit conveyed by the fruit conveying means is conveyed while diffusing while being vibrated on the fibrous projections planted on the plate surface of the fruit supply amount control means. Then, the fruits are supplied to the fruit alignment means in an aligned state. At this time, some of the fruits spread by the fruit supply amount control means are not supplied to the fruit alignment means but overflow from the fruit supply amount control means to the fruit re-supply means and are returned to the fruit transport means.

[0006]

According to the present invention, the fruits are transported while being spread by the fruit supply amount control means, so that the fruits can be supplied in a state of being smoothly aligned to the fruit alignment means, and the efficiency of the automatic fruit boxing operation can be improved. improves. In addition, when a large amount of fruit is transported, a part of the fruit overflows from the fruit supply amount control means to the fruit re-supply means and is returned to the fruit transport means. It is possible to prevent the fruit from colliding with each other and damaging the fruit.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a first embodiment of a fruit supply amount adjusting device according to the present invention. Numeral 1 is a conveyor belt conveyor as a fruit conveying means, and it is preferable that the fruits to be conveyed have a lollipop and are relatively firm and flat. Here, persimmon is used as an example. The conveyor 1 transports the persimmon 2 from left to right on the drawing. Reference numeral 3 denotes an electromagnetic feeder as fruit supply amount control means. The electromagnetic feeder 3 has a large number of fibrous projections 4 planted on a plate surface, and the fibrous projections 4 vibrate, and the density of the persimmon 2 at each location in the vertical direction in the drawing is reduced. It is transported from left to right while diffusing so as to be uniform. Reference numeral 5 denotes an alignment conveyor as fruit alignment means, which has a plurality of frames having a predetermined interval, and the belt conveyor 7 moves below the frame 6 from left to right in the drawing.

Reference numeral 8 denotes a return belt conveyor as fruit re-supply means, which is provided along the entire length of the conveyor belt conveyor 1 and the electromagnetic feeder 3, and conveys fruits from right to left in the drawing. Reference numeral 9 denotes a guide portion provided at the end of the return belt conveyor 8, which hits the persimmon 2 conveyed on the return belt conveyor 8, and returns the persimmon 2 to the conveyor belt conveyor 1. It is a plate-like one inclined at a angle.

Numeral 10 denotes a fruit reversing device provided on the conveyor belt conveyor 1 for ensuring that the persimmons 2 to be boxed are all oriented in the same direction, for example, the doll is facing downward. The fruit reversing device 10 may be provided with a long hair roller around the rotating shaft 11 like a conventional one, but since the reversing rate is not so high, the present invention replaces this with urethane or the like. The sponge-like substance 12 is wound.

The rotation speed v of the fruit reversing device 10 is lower than the speed V of the conveyor belt conveyor 1 (v <V). Thus, as shown in FIG. 3, when the fruit inverting device 10 comes into contact with the face of the persimmon 2 where the candy is located, the candy becomes the sponge-like substance 12.
It's hard. The lower part of the persimmon 2 is regulated by the speed V of the conveyor belt conveyor 1, and the upper part is regulated by the rotation speed v of the reversing device 10, so that the lower part moves quickly and the fruit is reversed. When the face without the fairy comes in contact with the fruit reversing device 10, the persimmon 2 moves without being reversed without being regulated by the speed of the fruit reversing device 10.

Next, the operation of the present invention will be described. First, the grade and size were sorted by a fruit sorter (not shown).
That is, the classified persimmon 2 is supplied to the conveyor belt conveyor 1. The persimmons 2 move on the transport conveyor 1, and are all aligned by the fruit reversing device 10 provided on the transport belt conveyor 1 such that the face with the candy faces downward, and is transported to the electromagnetic feeder 3. Due to the vibration of the electromagnetic feeder 3, the persimmon 2 is distributed uniformly over the entire length of the electromagnetic feeder 3. Then, the persimmon 2 is supplied to the alignment conveyor 5 and aligned in each frame 6. The aligned persimmons 2 are adsorbed by an adsorption unit (not shown) as described in JP-A-63-82914 and packed in a box.

At this time, the persimmon 2 which cannot be supplied to the alignment conveyor 5 and overflows falls from the electromagnetic feeder 3 onto the return belt conveyor 8 (see FIG. 2). The conveyor belt 1 is conveyed in a direction opposite to that of the conveyor belt 1 and collides with the guide section 9, moves to the start end of the conveyor belt conveyor 1, and is supplied again. Further, as shown in FIG.
If the position of the alignment conveyor 5 is set so that the upper part of the frame 6 is lower than the electromagnetic feeder 3, the disadvantage that the persimmon 2 hits the frame 6 and is not accommodated in the frame and becomes jammed can be solved.
