Thereby, the packaging box in which the articles on the installation table 8 are packed can be carried out.

Next, the operation of the automatic box packing device according to the present invention will be described.

The articles placed on the article mounting portion on the belt conveyor 11 are carried by the belt conveyor 11 to the orbital position of the scraping plate 21 on the belt conveyor 11. The scraping plate 21 is movable back and forth in a direction perpendicular to the traveling direction of the belt conveyor 11, and one end of its movement track is provided on the belt conveyor 11. It is scraped by the plate 21 and taken out of the belt conveyor 11.

A middle plate 6 is provided in the middle of the moving orbit of the scraping plate 21 as shown in FIG. 4, and a movable plate 31 is provided at the other end of the moving orbit at the retracted position. Thus, the article gathered by the scraping plate 21 can be smoothly carried onto the movable plate 31. Further, the belt conveyor 11 is arranged so that the article can be accurately placed on the movable plate 31.
A partition 12 may be provided on the top to guide the location of the item. Alternatively, a partition line may be simply displayed on the belt conveyor instead of the partition 12.

The standby position for retracting the articles, which is one end of the moving path of the scraping plate 21, and the retreat position are determined by the cylinder 24 and its rod 25. The articles are moved from the belt conveyor 11 to the movable plate 31. Because it carries up to, it may be at both ends of this range. In addition, as shown in FIG.

At this time, since the movable plate moving rod 32 of the movable plate 31 is disposed on two sides of the movable plate 31 parallel to the cylinder 24 for parallel movement of the scraping plate, the movable plate moving rod 32 causes the scraping plate 2 to move.
The track 1 is not obstructed and does not hinder the movement of the article. The movable plate 31 can be moved up and down by moving the two movable plate lifting cylinders 38 at the same time. By moving only one of the movable plate lifting cylinders 38, the moving direction of the scraping plate 21 can be adjusted. The movable plate 31 can be inclined in the direction. By these operations, the movable plate 31 is lowered to a predetermined lower limit position, and the movable plate 31 is tilted.
The article carried above can be stored in a packaging box placed under the movable plate 31.

That is, as shown in FIG. 5, the movable plate 31 on which the article 17 is placed can be stored in all the arms 33 by simultaneously storing the rods 39 of the two movable plate lifting cylinders 38.
And all the movable plate moving rods 32 also descend. Along with this, the movable plate 31 descends to a predetermined lower limit position while maintaining the parallel state as shown by the dashed line in FIG. Although the lower limit position is at the lowest level up to the bottom of the packaging box 16, it can be arbitrarily determined according to the presence or absence of an article in the packaging box, the type of the article, and the like. Next, by pulling out the rod 39 of one of the cylinders 38, the arm 33 on one side is pulled up, and accordingly, the movable plate moving rod 32 on one side rises. Thereby, as shown by the two-dot chain line in FIG. 5, the movable plate 31 can be inclined, and the articles 17 on the movable plate can be stored in the packaging box 16.

Next, the movable plate 31 is returned to the original position by returning the movable plate lifting cylinder 38 to its original state.

Detection marks are provided at predetermined intervals on the belt conveyor 11 in order to detect that an article placed on the article mounting portion of the belt conveyor 11 has arrived at the standby position of the scraping plate 21 due to the conveyance of the belt conveyor 11. The detector of the detection mark is installed at an appropriate position of the apparatus main body 1 so as to detect that the article has reached the detection position of the scraper plate 21. When the detector detects that the article has arrived at the standby position of the scraping plate 21, the scraping plate 21 operates to scrape the article on the belt conveyor 11 and convey it to the movable plate 31 at the retracted position. The scraping plate 21 is then moved upward by the cylinder 22 and returns to the standby position,
The scraping operation is repeated according to the detection of the next article by the detector.

Next, the movable plate 31 detects that the cylinder 22 of the scraper plate 21 has moved upward by a detector provided at an appropriate position, moves downward, and inclines to move the article into the packaging box. Fit. The height at which the movable plate 31 descends is set in advance in accordance with the type of articles to be stored, and the direction of inclination is set in advance in accordance with the number and position of rows to be stored in the storage box. For example, in the case of FIG.
Since the articles are stored in one row, the inclination is set to be alternately performed once. The movable plate 31 containing the article returns to its original state, and repeats the operation of storing the article as the cylinder 22 moves up next.

Finally, the carry-out plate 41 counts the number of actuations of the movable plate 31 by a counter installed at an appropriate position.
When the preset number of times of packing completion is reached, the carry-out plate moves, and the packaging box is carried out. Thereafter, the operation returns to the original position, and the operation of carrying out the packaging box is repeated according to the set number of times of movement.

By repeating these operations,
The articles placed on the mounting portion of the belt conveyor 11 are automatically boxed, and the boxed packaging boxes are sequentially carried out.
