Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a storage box reversing device for reversing a storage box containing contents such as fruits and removing the contents.

Conventionally, when taking out the contents from the storage box, the contents were directly inverted from the storage box onto the ejection belt and discharged, but this had the disadvantage that the height from which the contents fell was large and the contents were easily damaged.

According to the present invention, the opening of the storage box is inverted while being shielded, and the opening is gradually opened to gradually discharge the contents. The purpose is to prevent damage and to facilitate the removal of contents.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In the figure, reference numeral 1 denotes an annular reversing frame supported on rollers 5 and 7 rotatably provided on a base 3, and is rotated via the rollers 5 by the drive of a motor 9.

Reference numeral 11 denotes a conveyor which is supported by the reversing frame 1 and reversed together with the reversing frame 1, and the belt 13 is rotated around pulleys 15 and 17.

A motor 19 is fixed to the base 3, and rotates the belt 13 by rotating a sprocket 29 coaxially fixed to the pulley 15 via a sprocket 21, a chain 23, a sprocket 25, and a chain 27.

Reference numeral 31 denotes a flexible cushion body made of an elastic material such as sponge rubber, which is fixedly provided on the surface of the belt 13, and whose surface is formed into a corrugated shape.

Reference numeral 33.33 denotes a presser stand fixed to the reversing frame 1 in a direction parallel to the upper and lower surfaces of the belt 13 of the conveyor 11 at appropriate intervals, and rotatable rollers 35, 35. ... are installed side by side.

37 is a carry-in conveyor for carrying in the storage box 39 in the direction of arrow A in FIG.
,... are arranged in parallel.

43 is a stopper that locks and stops the storage box 39 of the carry-in conveyor 37.

Reference numeral 45 denotes a take-out device for taking out the contents 47 from the storage box 39. A drop port 53 is provided between the upper surface of the conveyor 11 and a carry-out device 51 provided on substantially the same plane. A take-out conveyor 55 is provided which conveys the contents 47 in the direction of the arrow in FIG.

57 is a guide plate that guides the contents 47 falling from the drop port 53 to the take-out conveyor 55.

Reference numeral 59 denotes a belt of the take-out conveyor 55, which is rotated at a faster speed than the belt 13 of the transport conveyor 11 by being passed around a pulley 61 and the like.

LS1 and LS2 are limit switches fixed to the base 3, and are activated by coming into contact with an operating piece 63 fixedly provided on the reversing frame 1.

5OL1 is a cylinder 6 that operates the stopper 43.
This is a solenoid for a solenoid valve (not shown) No. 5.

PH1, PH2, . . . PH5 are photoelectric switches that detect the storage box 39.

In the above configuration, the storage box 39 conveyed by the carry-in conveyor 37 is stopped by the stopper 43,
The two storage boxes 39 and 39 are locked and the switch PH4,
When PH5 is activated, the stopper 43 descends,
The two storage boxes 39.degree. 39 are moved onto the presser foot 33 in the lower position.

When the storage box 39 is removed from the positions of the switches PH4 and PH5, the stopper 43 rises.

When two storage boxes 39 are placed on the presser foot 33, the switch PH1
PH2 is activated at the same time, and the conveyor 11 is stopped after a certain period of time has elapsed.

Subsequently, the motor 9 is driven, the reversing frame 1 is reversed, and the actuating piece 63 is activated by the limit switch LS1. It comes into contact with either LS2 and stops at a position rotated 180 degrees.

The storage box 39 is inverted while being held between the presser stand 33 and the cushion body 31 on the transport surface of the transport conveyor 11.

After a certain period of time has passed after the reversal stops, the conveyor 11 rotates and sends out the storage box 39 onto the unloading device 51.

At this time, the storage box 39 should be placed at the drop opening 5 with its opening facing down.
3, the contents 47 gradually move from the drop port 53 onto the take-out conveyor 55 and are discharged to the outside.

The storage box 39 is carried out by the conveyor 11, and the next storage box 39.
3, and the work is carried out continuously.

As described above, the present invention provides a transport conveyor for reversing the storage box with the opening thereof shielded, and a drop port is provided at the end of the transport of the storage box after the reversal, and the container falls from the drop port. The downward opening of the storage box is provided with a take-out conveyor for transporting the contents at a faster speed than the transport conveyor, and an unloading device for transporting the storage box above the take-out conveyor. When the container is gradually carried out while being shielded, the opening of the storage box gradually approaches the drop port from the tip side, and the opening of the storage box is gradually opened, which allows the contents to be gradually removed from the drop port. When the contents are dropped and discharged onto the take-out conveyor, since the take-out conveyor is approximately horizontal, the contents taken out onto the take-out conveyor are less likely to roll on the take-out conveyor, and there are fewer collisions with each other due to rolling. , the contents are less likely to be damaged.

Moreover, since the take-out conveyor conveys the taken contents at a faster speed than the transport conveyor, the contents taken out onto the take-out conveyor do not stagnate in a mountain near the bottom of the drop port, but are kept level. It can be taken out.

Therefore, even if the head difference between the transport conveyor and the take-out conveyor is set to be extremely small, the contents falling from the drop opening can be smoothly taken out by the take-out conveyor.

Therefore, the height of the contents falling from the drop opening is small, the impact applied to the contents when falling is small, and the contents can be taken out smoothly without being damaged.

This is particularly advantageous when the contents are spherical and easily damaged, such as fruits.
