Description

[Detailed Description of the Invention] The present invention relates to a boxing device for fruits such as apples whose surfaces are easily damaged.

When mechanically packing fruits such as apples and peaches whose surfaces are easily damaged during handling, the fruit supplied from the fruit feeding mechanism to the fruit storage box may be placed on the bottom or side of the storage box, or if the fruit is already in the fruit storage box. It is necessary to take measures to prevent scratches that occur when the fruit collides with the fruit stored in the box.

For this purpose, the present applicants have proposed, for example, that the fruit feeding mechanism is placed in a fruit storage box with its top open, and that the weight of the fruit supplied from the fruit feeding mechanism and accommodated in the fruit storage box is used to store the fruit. By lowering the box in sequence,
A device has been proposed in which the boxing operation is performed while reducing the height difference between the feeding end of the fruit feeding mechanism and the fruit storage box, thereby reducing the occurrence of fruit damage.

However, in this device, the position at which the fruit is fed from the fruit supply mechanism into the fruit storage box is fixed, so the fruits are piled up high in one place and then dispersed inside the fruit storage box, which may cause collisions between fruits. There was a disadvantage that the number of lesions increased, and the occurrence of scars increased accordingly.

The present invention was made to solve the above-mentioned drawbacks, and the feeding end of the fruit feeding mechanism can be raised and lowered into the fruit storage box, which is installed to rotate horizontally with an open top. By providing a sensor at this feeding end that sends a signal to raise the fruit feeding mechanism when it comes into contact with the fruit fed into the fruit storage box, and to lower the fruit feeding mechanism when it does not come into contact with the fruit, the fruit feeding It is an object of the present invention to provide a fruit packing device which can pack fruits fed from a mechanism into a fruit storage box evenly and while keeping the height difference to a minimum, thereby reducing the occurrence of damaged fruit. be.

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 has an open upper part;
This fruit storage box has a substantially square plan view, and the bottom of this storage box 1 is provided with support legs 1a that form a space into which a fork of a forklift is inserted.

The storage box 1 is supported horizontally by a vertical rotating shaft 2, and is placed on a turntable 3 that is slightly larger than the planar shape of the storage box 1 and has a substantially square shape, so that it rotates in the direction of the arrow in FIG. It has become.

A supply end 4a of the fruit supply mechanism 4 is exposed inside the storage box 1 from above.

The fruit supply mechanism 4 includes a pair of left and right frames 5 that are L-shaped.
, 5, a pair of chinos 11, 11 are endlessly stretched along the length direction of the frames 5, 5 via each pair of driving sprocket wheels 6 and driven sprocket wheels 7.8.9. A large number of cross pars 12, 12... are installed between the chains 11, 11 at predetermined intervals, and a rubberized cloth belt 13 is continuously attached to each cross par 12, and a fruit is attached to the inside between the cross pars 12, 12. Accommodation recess 13a
3 and 4, and the feeding end 4a faces the inside of the fruit storage box 1 as described above. A discharge roller 14 having an engagement groove 14a on its circumferential surface that engages with the cross spar 12 is installed, and between the sprocket wheels 9, there is a passage from the back of the rubberized cloth belt 13 to the fruit storage recess 13a. An extrusion roller 15 for extruding the stored fruit A is mounted eccentrically with respect to the axis of the sprocket wheel 9.

Although not shown, the fruit supply mechanism 4 is equipped with an elevating mechanism that moves up and down relative to the fruit storage box 1, and is configured to move up and down with the rotating shaft 6a of the drive sprocket wheel 6 as a fulcrum.

Furthermore, rotational power is transmitted from the motor 16 to the rotating shaft 6a.

The fruit discharging position of the supply end 4a is such that the rotating shaft 6a moves slightly back and forth as shown in FIG. 2 so that it moves almost vertically when going up and down. As shown in FIG. 1, the fruit storage box 1 is arranged so as to be discharged in the direction of rotation at a position away from the center of rotation.

A discharge guide plate 17 is provided at this fruit discharge position.

Furthermore, the supply end 4a of the fruit supply mechanism 4 is provided with first and second sensors 18 and 19 for detecting the surface on which the fruit A is deposited, as shown in FIGS. 5 and 6.

The first sensor 18 includes a detection plate 20 whose one end is pivotally supported on the frame 5 by a pin 20a and whose other end is bent along the rotational direction of the fruit storage box 1, and the detection plate 20 is in contact with the fruit A. The first microswitch 2 is turned on by the detection plate when
1, and the second sensor 19 includes the discharge guide plate 17 whose one end is pivotally supported to the frame 5 by a pin 22, and the discharge guide plate 17 when the bottom surface of the guide plate 17 comes into contact with the fruit A.
and a second microswitch 23 that is turned on.

Then, the first and second microswitches 21.2
3 is connected to send a signal to the lifting mechanism,
When one or both of the microswitches 21 and 23 is turned on, the fruit supply mechanism 4 is raised, and when both microswitches are turned off, the fruit supply mechanism 4 is raised after two seconds.
is configured to lower.

The fruit boxing device configured as described above is used by placing the fruit storage box 1 on the turntable 3, rotating the turntable 3 about the rotating shaft 2, and driving the fruit supply mechanism 4.

Fruit A fed onto the rubberized cloth belt 13 by appropriate means
are accommodated in the four fruit storage sections 13a by their own weight and transported in the direction of the arrow in FIG. The rubberized cloth belt 13, which is engaged with the matching groove 14a and secured to the cross spar 12, is connected to the fruit storage recess 13a.
The fruit A is pushed out by a discharge roller 14 so as to be pushed outward, and at the same time, the fruit A is pushed by a push roller 15 and is discharged and stored in the fruit storage box 1 via a discharge guide plate 17.

When the fruit A is not stored in the fruit storage box 1, the feeding end 4a of the fruit supply mechanism 4 is positioned close to the bottom of the fruit storage box 1 by the action of the sensors 18 and 19, and the fruit A is not stored in the fruit storage box 1. When A begins to be accommodated, it moves up and down by the operation of sensors 18 and 19, as shown in FIGS. 5 and 6.

To explain this operating state in a little more detail, the supply end 1
As shown in FIG. 1, the fruit A discharged from the fruit storage box 4a is stored in one place without clumping together as shown in FIG. The detection plate 20 contacts the pin 20 a
The first microswitch 21 is turned on and the fruit supply mechanism 4 is raised.

When the first microswitch 21 is turned off by this rise, the fruit supply mechanism 4 descends two seconds later, and the detection plate 20
contacts the fruit A, the microswitch 21 is turned on, and the fruit supply mechanism 4 rises again.

While repeating such raising and lowering operations alternately, the supply end portion 4a rises following the stacked surface of the fruit A whose height is gradually increasing.

FIG. 6 shows that the first sensor 18 is off and the second sensor 19 is off.
Although this shows the state of "O", it is possible to achieve most of the objectives with just one sensor.

The fruit A stored in the fruit storage box 1 in this way is
By rotating the fruit storage box 1, the fruits A are not piled up in one place but are piled up almost evenly, and the feeding end 4a is almost the same as the bottom of the fruit storage box 1 or the fruits A piled inside the storage box. Fruit A is discharged without creating a drop.
The fruits do not collide strongly with the bottom or side surfaces of the fruit storage box 1 or with the fruits already stored, thereby preventing the occurrence of damage.

In addition, it is preferable to provide a mechanism that stops driving the turntable 3 and the fruit supply mechanism 4 when the fruit A is stored at a desired height in the fruit storage box 1.

As explained above, according to the fruit boxing device according to the present invention, the feeding end 4a of the fruit feeding mechanism 4, which can be raised and lowered, faces into the fruit storage box 1, which is installed so as to rotate in the horizontal direction. Fruit A supplied into the storage box at the supply end 4a
Sensors 18 and 19 are provided that emit a signal to raise the fruit supply mechanism 4 when it comes into contact with the fruit, and to lower the fruit supply mechanism when it does not come into contact with the fruit. The fruits can be housed almost evenly within the container while keeping the height to a minimum, and therefore can be automatically packed into boxes without damaging the fruits.
