Abstract

PURPOSE:To shorten the process and time of the encasing and increase the efficiency of the encasing operation. CONSTITUTION:A multiplicity of cucumbers sorted into grades are loaded one after another on a feed conveyor of a transport conveyor system and, as they are carried on the feed conveyor, each of the cucumbers is oriented by acceleration on accelerating rollers and accelerating conveyors 8. Simultaneously a cucumber-boxing machine 3 is operated, which moves suction pads 18 each in parallel with the cucumbers on the accelerating conveyors 8 and in the direction of the feeding horizontally; each suction pad 18 is put in tight contact with the upper circumferential surface of one of the cucumbers and made to hold it by suction. As many cucumbers as the suction pads 18 that thus hold them are so gathered as to fit into a corrugated paperboard box and packed successively therein. This constitution enables shortening the distance for which many long objects must be carried, the process of their encasement, and the time required therefor.

[0003]

However, as described above, when a large number of each cucumber K ... Is once placed on the aligning conveyor 51 and conveyed, the space between the supply conveyor 50 and the cucumber box packing machine 52 is increased. Since the alignment conveyor 51 is provided in the above, the transport distance between the supply conveyor 50 and the cucumber boxing machine 52 becomes long, and it takes time and labor to transport and supply a large number of each cucumber K ... to the cucumber boxing machine 52. It takes time. In addition, by adding a process for mounting a large number of each cucumber K ... on the alignment conveyor 51, the work process becomes complicated and the work efficiency per unit time becomes poor. There is.

In view of the above problems, the present invention drives a long object boxing means to directly hold a large number of each long object placed on the conveying surface of a conveyer for boxing inside the box body. Therefore, it is possible to reduce the process and time required for boxing work,
An object of the present invention is to provide a long object boxing device capable of saving labor in boxing and improving efficiency.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a large number of long objects sorted by equal rank are placed on a conveyor for conveyance, and a large number of long articles conveyed by the conveyor are conveyed. A long object boxing device for boxing items inside a box,
On the conveyor for conveyance, a long object boxing device provided with a long object boxing means for aligning and holding an appropriate number of each long object conveyed by the conveyer in the same direction and packing the box inside the box body. It is characterized by being.

[0006]

According to the present invention, a large number of long objects sorted according to the equal rank are sequentially placed on the conveyor for transportation, and the means for packing the long objects is driven so as to be placed on the transportation surface of the conveyor for transportation. After the appropriate number of the mounted long objects are aligned and held directly in the same direction, the appropriate number of the long objects are boxed in the box while being aligned in the same direction.

[0007]

According to the present invention, an appropriate number of each long object placed on the carrying surface of the carrying conveyor is directly held and packed in the box body. The labor and work of placing each long item on a conveyor for alignment or an alignment tray can be saved, and the transport distance for transporting a large number of each long item can be shortened. The time can be greatly shortened, the work process can be simplified, and the labor and efficiency of the box packing work can be improved.
