Description

[Detailed Description of the Invention] This invention relates to a device for discharging objects contained in a case for discharging objects contained in a case by inverting the case.

Conventionally, when fruits are harvested, they are placed in a case and transported to a fruit farm, where the case is inverted on a conveyor to be transferred to a fruit harvesting machine. It was transferred to a conveyor. However, there was a drawback that soft fruits were damaged during this transition. Therefore, there was a drawback that a large amount of manpower and time was required to transfer the fruits in the case to the conveyor individually, and the processing capacity was not improved. In Japanese Patent Application Laid-open No. 54-111992, when feeding the storage boxes placed on the transport frame to the guide device, there is no feeding control device for the storage boxes, so the transfer intervals of the storage boxes are uneven, and the storage boxes are not horizontally moved. There is a drawback that when taking out the stored items in the transport section, the storage box becomes unstable and the stored items cannot be taken out in an orderly manner. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a device for discharging objects contained in a case, which can efficiently transfer the fruits contained in the case to a conveyor without damaging the fruits.

An embodiment of this invention in which fruits are transferred from a case containing fruits to a conveyor will be described.
First of all, FIG. 1 shows a side view of the device, in which fruits 2, which are objects to be stored, are stored in a case 1, and when the fruits 2 are harvested, they are carried to the fruit farm housed in the case 1. . Fruits 2 brought into the fruit farm are taken out from case 1 to be put into the fruit machine.
The cases 1 are placed on the upper surface of the placement frame 10 in order to be aligned on the alignment conveyor. A roller group 13 is disposed on the upper surface of this mounting frame 10, and this roller group 13 is driven by a drive motor 11 via a chain 12. A cylinder 14 is disposed on the mounting frame 10 in order to time the conveyance of the case 1, and when a stopper 14a disposed at the tip of the rod of this cylinder 14 protrudes from the roller group 13, the case 1 is locked, and when the stopper 14a is positioned below the roller group 13, the case 1 is conveyed to the left. A reversing frame 20 is connected to the left side of the mounting frame 10, and a drive motor 21 is disposed on the upper surface of this reversing frame 20, and a sprocket 21a fixed to the output shaft of this drive motor 21 and a sprocket 2
3, and a reversing chain 28 is wound around a first sprocket 23a, a second sprocket 24, a third sprocket 25, a fourth sprocket 26, and a fifth sprocket 27, which are coaxial with the sprocket 23. This inversion chain 28
The first sprocket 23a and the fifth sprocket 2
A semi-circular chain guide 29 is disposed between the case 1 and the case 7, and a conveying section 28a is formed. There is. Also, inversion chain 28
A belt 33 is disposed opposite to the conveying section 28a of the reversing frame 20, and this belt 33 is connected between the sprocket 21b fixed to the output shaft of the drive motor 21 disposed on the upper surface of the reversing frame 20 and the sprocket 31a. A chain 31 is wound around this sprocket 3.
A roller 32 is disposed coaxially with 1a, and a roller 34 is disposed oppositely to the lower part of this roller 32,
A belt 33 is wound between the rollers 34 and 32, and a guide 33a is disposed on the left side of the belt 33 to form a semicircular arc having the same shape as the reversing chain 28. Then, the case 1 conveyed by the roller section 13 is stopped by the locking pawl 30 of the reversing chain 28, and is reversed by 180 degrees while being transferred through the conveying section 28a of the reversing chain 28. At that time, the opening of the case 1 is closed by a reversing belt 33 moving at the same speed as the reversing chain 28 to prevent the fruit 2 in the case 1 from spilling out. Case ejection belts 42 and 43 are arranged at a distance from each other on the upper right side of the reversing frame 20, and the case ejecting belts 42 and 43 are driven by motors 44 and 45, and are reversed and transported by the reversing chain 28. The bottom of the case 1 is held and conveyed to the right, and the case 1 ejected from the case ejection belts 42 and 43 is placed on a case mounting table 60 disposed to the right of the case ejection belts 42 and 43. Ru. When the case 1 is reversed and transferred from the reversing chain 28 to the case discharge belts 42 and 43, the fruit 2 in the case 1 moves along the guide 41 that is inclined between the reversing frame 20 and the transfer frame 40. It rolls and is ejected from the case 1. The fruits 2 rolled on this guide 41 and discharged are placed on four rows of alignment belts 50, 51, 52, 53, 54, 55 arranged on the right side.
56 and 57. This alignment belt 50,
51, 52, 53, 54, 55, 56, and 57 are formed by two opposing belts arranged in a substantially V shape, and one of the two belts is arranged to move at a high speed. , alignment belts 50, 51, 5
2, 53, 54, 55, 56, 57, the fruits 2 arranged on each alignment belt 50, 51, 52, 5
3, 54, 55, 56, and 57, and are arranged one by one in a line and transferred to the next process, the fruiting process.

As described above, in the present invention, by providing the mounting frame with a stopper that is reciprocated by a cylinder, the cases can be sent out in an orderly manner, and the bottoms of the cases can be accurately engaged with the claws of the reversing chain to be transferred. At the same time, the case is sandwiched between the semi-circular chain guide and the guide, and the bottom of the case is locked with the claw of the reversing chain, so that the reversing chain can be moved without creating frictional resistance between the conveyor part, the guide, and the case. The case is locked by the claws and the belt, and in a stable state, the opening is turned over by 180 degrees, and the case is held down from both sides by the discharge guide while being discharged onto the contents and the guide. Therefore, the opening of the case will not be compressed or damaged by nails, so the object to be stored will not be compressed or damaged. In addition, in cases where the discharge has been completed,
Empty boxes can be smoothly sorted because they are sandwiched between the ejection belts and ejected toward the case mounting table with the openings facing downward.
