Abstract

PURPOSE: To pass an article at high speed by providing a shelf plate on the middle stage of a rectangular parallelopiped box body, and providing a fulcrum shaft and bearing for rotating a roller support plate on the front part of the shelf plate, and a motor with air cylinder or link device for pushing up the roller support plate on the rear part. CONSTITUTION: In a high speed sorting device for article, a linearly advancing carrying belt conveyor is longitudinally set, and in the starting point of a carrying article, a bar code for each sorting gate mounted on the article is read by a laser scanner and processed by a computer. When a sorting control signal is transmitted to a prescribed sorting device gate, an air cylinder A set on the rear part of a shelf plate is operated to push up a roller support plate 3, and the rear part of the roller support plate 3 is lifted with a fulcrum shaft 5 set on the shelf plate front part as the center. Thus, the rear part of the whole rotating roller R is instantaneously lifted obliquely, and the article is jumped out in the direction for rotating the roller, and sorted. Since the roller group is immediately recessed, the following article can pass the belt conveyor C at high speed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a novel apparatus for sorting a molded box shape or packed articles at high speed.

[0002]

2. Description of the Related Art Conventionally, in this type of article sorting method, a short belt conveyor or a rotating roller for sorting is installed between mainstream belt conveyors, and these are sorted by projecting a small amount vertically upward at a sorting point. The way was done. However, with this method, the straight running performance of the article is poor,
In addition, items could not be sorted and flowed.
There was only a processing capacity of about one piece, and there were many failures of the belt conveyor. In addition to this, a short belt conveyor is about 45
There was also a method of sorting by swinging left and right at an angle of °. However, in this device, there are many problems that the tip of the article bites into the belt conveyor or the article is splashed in the lateral direction.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus for sorting box-shaped or packed articles at high speed while transporting them at high speed.

[0004]

In order to achieve the above object, a rectangular parallelepiped box-shaped main body is provided, and an appropriate number of endless belt conveyors which rotate at a high speed in the front-rear longitudinal direction are provided on the upper surface of the main body. The belt conveyor is driven by a power motor installed at the bottom of the main body to drive and rotate a large number of pulleys installed on the side plates of the main body. Also, adjacent to the belt conveyor, each belt conveyor has a high speed of an appropriate length and thickness. A rotating roller is installed in the front-rear direction and rotatably installed on a roller supporting plate on the upper part of the main body. A roller rotation power motor is installed on the lower surface of the roller supporting plate, and the rotating roller is driven by several sets of belts. In addition, a shelf board is installed in the middle of the main body, a fulcrum shaft and a bearing for rotating the roller support plate upward are installed in the front part of the main body, and an air cylinder or an air cylinder that pushes up the roller support plate diagonally is installed in the rear part. Re Is an article faster sorting device formed by installing a click-equipped motor.

[0005]

The article high-speed sorting apparatus of the present invention configured as described above is provided with a straight conveyor belt conveyor before and after the apparatus, and the starting point of the conveyed article is different for each sorting gate attached to the article. When the bar code is read by a laser scanner and processed by a computer and a sorting control signal is sent to the gate of a predetermined sorting device, an air cylinder installed at the rear of the shelf plate of this device operates to push up the roller support plate and move it to the front of the shelf plate. Since the rear part of the roller support plate rises around the fulcrum shaft installed in the section, and therefore the rear part of all the rotating rollers are lifted up diagonally for a moment, this article is bounced in the direction of rotation of the roller to be sorted. is there. Then, since the roller group is immediately retracted, the subsequent articles can pass through the belt conveyor at high speed.

EXAMPLES Examples will be described with reference to the drawings.
In FIG. 1, a rectangular parallelepiped box-shaped main body (1) is provided, and a belt conveyor C which rotates the upper surface of the main body (1) in the longitudinal direction at a high speed in the longitudinal direction is provided at four.
The belt conveyor C of each line is constructed by the main body (1)
A large number of pulleys P installed on the side plate 2 of the main body (1) are driven and rotated by a power motor M1 installed on the bottom of the belt conveyor C, and adjacent to the belt conveyor C, four pulleys of appropriate length are provided. And a high-speed rotating roller R having a thickness are installed in the front-rear direction and rotatably installed on the roller supporting plate 3.
A roller rotation power motor M2 is installed on the lower surface of the roller, a rotary roller R is rotated by driving several sets of belts B, and a shelf board 4 is installed in the middle stage of the main body (1). This is a high speed article sorting apparatus in which a fulcrum shaft 5 for rotating the support plate 3 upward and the bearing 6 are installed, and an air cylinder A for pushing up the roller support plate 3 is installed in the rear part. In the drawings, CPU. Is a computer, G is an article,
PH is a phototube.

[0007]

Since the present invention is constructed as described above, it has the following effects. Unlike the conventional device, this high-speed sorting device for articles sorts out the rotating rollers installed between several belt conveyors of this device diagonally by the roller support plate all at once for a predetermined time according to the sorting control signal from the sender. Since the conveyed articles are sorted and sorted, the succeeding conveyed articles can be circulated backward at high speed without any trouble. In particular, this device is extremely effective in sorting newspaper packages that have severe time restrictions.
