Description

[Detailed description of the invention] (a) Field of the invention This invention relates to a fruit boxing device that packs fruits into predetermined boxes.

(b) Background of the invention In order to mechanically pack fruits into boxes, it is preferable to arrange the fruits in advance in storage rows within a box, and then move the fruits in this arranged state to a boxing position and box them.

During the transition from the above-mentioned fruit alignment position to the boxing position, if the fruit is adsorbed by a suction satsuka and transferred, marks of this adsorption will be left on the fruit, reducing the commercial value of the fruit. Even if the fruit is pinched, there is a problem that the pinching may damage the fruit.

(c) Purpose of the invention This invention enables the fruits to be reliably packed in boxes without damaging them by rapidly pulling out the alignment board on which the fruits are arranged and placed on the top surface, allowing the fruits to fall and then being packed in boxes. The purpose is to provide fruit boxing equipment.

(d) Summary of the invention This invention is a fruit boxing device in which an alignment plate is removably provided in relation to all position regulating plates, and the alignment plate is rapidly pulled out at the boxing position to drop the fruits and pack them into boxes. It is characterized by

(e) Effects of the invention According to this invention, the fruit falls when the alignment board is pulled out and is packed in a box, so there is no possibility of suction marks, scratches, etc. In addition, since the alignment unit including the alignment plate is moved to the top of the box at the packing position and the alignment plate is rapidly pulled out, the alignment of the boxes directly below will not be disturbed and the alignment will remain in good condition. Fruits can be packed in boxes.

Furthermore, since the boxing device can be composed of an alignment unit, a moving device for moving the unit, and a pulling device for pulling out the alignment plate, there is no element that increases the size of the device, and the boxing device can be downsized. can.

(F) Embodiment of the invention An embodiment of the invention will be described below in detail based on the drawings.

The fruit 14 is fed to the first feeding device 11 manually. For example, if the fruit 14 is a persimmon, the persimmon is placed on the conveyor belt 15 with its calyx facing downward.

When the fruit 14 is supplied to the second feeding device 12 by driving the above-mentioned conveyor belt 15 in the conveyance direction, the front and rear conveyor belts 24 and 25 driven in opposite directions and the left and right guides Board 38,3
8, the fruits 14 are transferred to the sorting unit 39 while being moved in a circulating state.

The boxing device 13 includes both hydraulic cylinders 49 and 52.
is being operated downward, the first rail member 4
6, and the frame 50 is in an inclined state, the alignment unit 39 and the guide plate 60 in the preceding stage thereof
is tilted, the electromagnet 57 attracts and fixes the alignment unit 39, and the vibration generator 54 generates vibrations.

Note that since the alignment unit 39 is fixed to the electromagnet 57 by attraction, no noise is generated even if the vibration generator 54 applies vibration.

Therefore, the fruit 14 is
When the fruit 14 is supplied, the fruit 14 is moved to the alignment unit 39 by the inclination and vibration of the alignment plate 40 and the guide plate 60.
The fruits 14 that have been moved to the inclined lower edge side of the alignment plate 40 and have reached the position regulating plate 41 at the lower edge are aligned in a line, and the fruits 14 that are aligned above the alignment plate 40 are aligned on the left and right position regulating plates 42, 42. Accordingly, the arrays are arranged in parallel, and the subsequent arrays of fruits 14 are similarly arranged in a grid pattern.

Note that when the fruit 14 moves, the position regulating plates 41, 4
2, but since these surfaces are made of an elastic material, they do not damage the fruit 14.

When the fruits 14 that can be boxed are arranged in the above-mentioned arrangement unit 39, the first and second feeding devices 1
The supply of fruit 14 by 1, 12 is temporarily suspended,
The vibration generator 54 stops vibrating, the first and second hydraulic cylinders 49 and 52 are operated, the first rail member 46 and the frame 50 are operated to a horizontal state, and the alignment unit 39 changes its posture to a horizontal state. be done.

Thereafter, the electromagnet 57 is turned off to release the adsorption of the alignment unit 39, and then the second hydraulic cylinder 52 is operated downward to tilt the frame 50, and this movement causes the concave portion 58 of the electromagnet 57 to
Then, the alignment unit 39 is disengaged from the protrusion 59, and the alignment unit 39 is placed in a slidable state.

Sliding body 63 placed on the second rail member 61
is normally waiting at the front end position of the second rail member 61, and as the alignment unit 39 rises, the first and second hooks 44,
45, the third and fourth hooks 65, 6 on the sliding body 63 side
7 engage with each other (see FIG. 6).

Next, the third hydraulic cylinder 64 is operated rearward, the sliding body 63 moves rearward, and the alignment unit 3
9 is moved to the boxing position (see FIG. 7), and then, by rapidly operating the fourth hydraulic cylinder 66, the alignment plate 40 of the alignment unit 39 is rapidly pulled out rearward and aligned with the alignment plate 40. The fruits 14... that were placed are still lined up and are placed in the lower box 68.
They fall into the interior and are stored in an aligned state (see Figure 8).

When the packaging of the fruits 14 is completed as described above, the fourth hydraulic cylinder 66 is operated forward to return the alignment plate 40 to its original state, and further,
By operating the third hydraulic cylinder 64 forward and moving the sliding body 63 forward, the alignment unit 39 is returned to the alignment position.

When the above-mentioned alignment unit 39 returns to the alignment position, the second hydraulic cylinder 52 is operated upward,
