Description

  In the present invention, an article is conveyed vertically from below to above or from above to below while horizontally supporting the article on the loading platform, and a horizontal traveling part at one end of the vertical conveying part forms a loading or unloading end of the article. The present invention relates to a conveyor in which a carry-out end or a carry-in end of an article is formed by a horizontal traveling unit at the other end of the conveyance unit.

  Conventionally, when an article such as a food is conveyed from below to above or from above to below, a method is adopted in which the conveyor is arranged obliquely at a gentle gradient and the article is conveyed along a slope.

However, the above-described inclined conveyor requires a relatively long conveyor to transport articles to a predetermined height, and requires an excessive installation space.
In addition, the article becomes slanted and easily slips and falls.

  The present invention provides a conveyor for eliminating the above-mentioned problems, and includes the following configurations A to F.

A. A pair of left and right outer drive chains that run endlessly in parallel, and a pair of left and right inner drive chains that run endlessly at the same speed as the outer drive chains in parallel inside the pair of outer drive chains.
B. A plurality of cargo beds having flexibility are provided.
C. Both sides of the front end or the rear end of each loading platform are connected and supported by the pair of outer drive chains, and both the rear end sides or both front ends of the loading platforms are connected and supported by the pair of inner drive chains.
D. In the pair of outer drive chains or the pair of inner drive chains, the drive chain connected to the rear end of the loading platform has a first single vertical traveling portion that vertically travels in advance, and the drive chain connected to the front end of the loading platform is There is a second single vertical traveling section that follows and vertically travels, and a vertical transport section that vertically operates while supporting the loading platform horizontally between the first and second single vertical traveling sections is formed.
E. The pair of outer drive chains and the pair of inner drive chains have a first parallel horizontal travel unit that horizontally travels in parallel with each other at the lower end of the vertical transport unit and horizontally supports and operates the loading platform. In the traveling part, a carrying-in end for carrying the article onto the loading platform or a carrying-out end for carrying the article from the loading platform are formed.
F. The pair of outer drive chains and the pair of inner drive chains have a second parallel horizontal traveling unit that horizontally travels in parallel with each other at the upper end of the vertical conveying unit to horizontally support and operate the loading platform. In the traveling part, a carry-out end for carrying out the article from the cargo bed or a carry-in end for carrying the article into the cargo bed is formed.

  As a suitable example, the loading platform is formed by braiding wire, and a pair of left and right loading platform side chains are disposed along the left and right sides of the loading platform, and both ends of the braided wire are supported by the pair of loading platform side chains. To.

  According to the present invention, it is possible to immediately move from the carry-in end of the article to the vertical carrying unit and to the carry-out end, that is, configure a vertical carrying unit that conveys the article vertically between the carry-in end and the carry-out end. Therefore, the length of the conveyance part which conveys articles | goods up and down can be minimized, and installation space can be reduced significantly.

  In addition, the article can be horizontally supported and conveyed at each of the carry-in end, the vertical conveyance unit, and the carry-out end, and the article can be reliably prevented from falling or breaking.
