DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor suitable for transporting small, soft and water-rich foods, such as raw materials for shirasu fish and dried radish, and more particularly, to a conveyor which is spread from a conveyor belt. Related to the device.

[0002]

2. Description of the Related Art In general, in a conveyor for conveying soft small foods, a vibrating device is added to a belt conveyor, and the vicinity of the end of the belt conveyor is vibrated up and down to diffuse and feed the food to be conveyed. Further, there has been proposed a device for blowing compressed air onto a conveyor belt by sending compressed air in order to wind-select the food to be transported.

[0003]

However, when the conveyed food is dropped by vibrating the conveyor belt, the spread is uneven due to mechanical diffusion.

[0004]

The above-mentioned object is achieved by winding a conveyor belt made of a porous material between a starting roller and an ending roller, and connecting the ending roller to an upper side disposed vertically. An air nozzle that is configured with at least two rollers and a lower roller, and that is located between the upper roller and the lower roller and that is located on the back surface of the conveyor belt and opened forward in the traveling direction of the conveyor belt. It is solved by providing. In this case, it is preferable to provide a receiving plate made of a porous member for receiving the conveyed food blown out from the air nozzle at a position beyond the conveyor belt of the air nozzle. Preferably, the receiving plate includes a front plate facing the conveyor belt and a porous side plate extending from both sides of the front plate toward the conveyor belt. A conveyor belt made of a porous material refers to a belt having many small holes, such as a resin mesh belt and a stainless steel mesh belt. Generally, a polyester material having a small hole of about 0.5 mm square is often used.

[0005]

The upper surface serving as the conveying surface of the conveyor belt is bent forward and downward by an upper roller and a lower roller in the vicinity of the end. Air is blown from the back surface of the portion of the conveyor belt bent downward by an air nozzle, and the conveyed food left on the conveyor belt is blown forward in the traveling direction. Most of the conveyed food blown off from the conveyor belt by the air nozzles loses speed and falls downward, and a part is received by the receiving plate and falls. In addition, the conveyed food that is blown off from the conveyor belt and is about to spread in the width direction is received by the side plate attached to the front plate, and falls inside the side plate.

BRIEF DESCRIPTION OF THE DRAWINGS The drawings show an embodiment of the present invention. In FIG. 1, reference numeral 10 denotes a transport conveyor for transporting soft small foods. The conveyor 10 has caster wheels 21
The frame 11 is supported on a carriage 20 provided with a slanting support via columns 22, 22.

The frame 11 has a main body 12, a lower roller support frame 13 and an upper roller support frame 14 screwed to both ends thereof, and the space between the main body 12 and the two support frames 13, 14 can be tightened and relaxed. Is fixed to the bolt 15. Reference numeral 16 denotes a drive frame provided integrally with the lower roller support frame 13,
An electric motor 17 with a speed reducer is supported.

Reference numeral 25 denotes a starting roller which is rotatably supported by the lower roller supporting frame 13, and is driven by a motor 17 with a speed reducer via a chain 26. Reference numeral 27 denotes a trailing end roller supported by the upper roller support frame 14. A conveyor belt 28 is wound between the start roller 25 and the end roller 27. Reference numeral 29 denotes an idle roller.

The end roller 27 is provided on the conveyor belt 2.
8, a lower roller 27a disposed on the front lower side in the traveling direction of 8,
The upper roller 27b is disposed above the lower roller 27a. Therefore, the conveyor belt 28 is inclined forward and downward between the lower roller 27a and the upper roller 27b. But conveyor belt 2
The fact that 8 is inclined forward and downward at this part is based on this invention.
The lower roller 27a and the upper roller 2 are not essential requirements.
7b may be arranged vertically and the conveyor belt 28 may be vertical.
7b may be closer to the start end side.

A small space is provided between the lower roller 27a and the upper roller 27b. The space is located behind the conveyor belt 28 and is opened forward in the traveling direction of the conveyor belt 28. An air nozzle 30 is provided. Reference numeral 31 denotes a blower supported by the cart 20, and its discharge port is connected to the air nozzle 30 via a flexible pipe.

Reference numeral 40 denotes a receiving plate formed of a resin mesh, a wire mesh, a perforated belt, and other porous members supported by the upper roller supporting frame 14, and is provided to receive the conveyed food accompanying the air blown out from the air nozzle 30. ing. The receiving plate 40 has a front plate facing the conveyor belt 28 side and the conveyor belt 28 from both sides of the front plate.
A plan view is formed in a substantially U shape by the porous side plate extending to the side. Reference numeral 45 denotes a receiving box for food to be transported disposed below the receiving plate 40.

Numeral 50 denotes a feeding conveyor for feeding the small fish and the dried radish, which are the food F to be transported, to the transport conveyor 10, and the transported food F falling from the charging conveyor 50 is located at the start end of the transport conveyor 10. Supported diffuser 5
Fall on 1 The diffuser 51 is a horizontal rotating plate 5 driven by a vertical shaft 52 supported on the main body 12.
3 Around the horizontal rotating plate 53, three sides are surrounded by a wire mesh 18 arranged on both sides of the conveyor belt 28 and a wire mesh 19 arranged on the starting end side. Therefore,
When the conveyed food F falls from the charging conveyor 50 onto the horizontal rotating plate 53, the three sides around the horizontal rotating plate 53
Even if the conveyed food F is put in a lump, the conveyed food F is broken up and shaken onto the conveyor belt 28 because it is surrounded by 19.

According to the above embodiment, the conveyor belt 2
When the conveyer belt 28 reaches the end, the conveyed food F that is placed and conveyed on the upper surface of the upper roller 8 drops forward by gravity, and also between the upper roller 27b and the lower roller 27a from the air nozzle 30. The air is blown forward by the blowing air flow, is received by the receiving plate 40, and falls into the lower receiving box 45. That is, the conveyor belt 28 is not vibrated without vibrating the conveyor 10.
The upper transported food F can be taken out.

FIG. 3 shows an example in which the transport conveyor 10 is incorporated in a system for removing contaminants mixed in the drying of the whitened shirasu. Here, it falls from the charging conveyor 50,
The conveyed food F, which is a boiled boiled whitebait fish, is received by the conveyor 10 according to the present invention, and the air nozzle 30 blows off the water attached to the whitebait fish, and at the same time, loosens and blows it out to the wind selection device 60. The wind selection device 60 removes shrimp and other contaminants mixed in the white fish.

FIG. 4 shows an example in which the conveyor 10 is incorporated into a system for removing broken or small items from boiled air. Here, boiled dried vegetables sent by the feeding conveyor are sorted by the wide sorting conveyor 7.
It is used to spread the material on a 0-belt in a wide and uniform thickness. In the figure, 71 is an air nozzle, and 72 is a product take-out conveyor.

[0017]

According to the first aspect of the present invention, the conveyed food F is blown off from the conveyor belt by the airflow, loosened and sent to the next step in a state where excess moisture is separated. Further, since the conveyed food F is lowered from the conveyer by the air flow, the conveyer itself vibrates as in the case of using the vibrator, and the stability of the installation is not impaired. According to the second aspect, the conveyed food blown off from the conveyor belt by the air nozzle is received by the receiving plate and taken out to a predetermined position. According to the third aspect, the food to be transported blown off from the conveyor belt by the air nozzle is prevented from spreading to the surroundings by the front plate and the side plates, and the unsanitary environment can be avoided. And so on.
