Description

[Detailed Description of the Invention] The present invention relates to an elastic belt, and in particular, to a pair of endless conveyors with their conveying surfaces facing each other, the belt is used to hold an article between the conveying surfaces in an upward or downward direction such as in a vertical direction. The present invention relates to a conveying device for conveying articles, which is installed on an endless conveyor that acts as a support side and an endless conveyor that acts as a presser side for articles.

When an article is conveyed vertically or in an inclined direction, for example, upwardly, conventionally, as shown in FIG. 1, a supporting conveyor a is used as a first endless conveyor, and a holding conveyor b is used as a second endless conveyor. are provided facing each other, and both conveyors a.

By rotating conveyors b synchronously in opposite directions and carrying the article d into the carry-in section C located below, the article d is sandwiched between the opposing conveyance surfaces of both conveyors a and b. A conveying device is used in which the material is raised, and the material is transported out from a transport section e located above.

In this case, an elastic belt composed of an elastic string body and a flexible sheet body is usually attached to the presser side conveyor b between endless drive chains disposed on both sides. It is required to be able to accurately hold down articles of different shapes and sizes, and not to cause poor conveyance or damage to the articles.

For this reason, it is necessary that the string body of the elastic belt and the sheet body are assembled so that they interact organically.
For this reason, elastic belts have complex structures or require many processing steps, such as sewing, in order to obtain a structure for holding the string body.

The present invention was devised in view of these points, and aims to improve the structure of an elastic belt and make it easier to manufacture.

Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

Reference numeral 1 denotes an endless sheet, and this sheet 1 is formed into an endless belt shape from flexible synthetic resin cloth, etc., and the sheets 1 and 1 are formed at regular intervals in the length direction, that is, the vertical direction, on the surface of the sheet 1. A plurality of cylindrical portions 2 having the same width are provided in parallel in the width direction, that is, the lateral direction, of the sheet 1, respectively.

In case 2, each cylindrical part 2 is made of a separate sheet piece with the same width as the sheet 1 and has a roughly U-shaped cross section. It is arranged at a predetermined position in the longitudinal direction, and is attached by attaching both ends of the piece 3 to the sheet 1 via one sewn part 4.

Reference numeral 5 designates an elastic string, and the elastic string 5 is made of an elastic string material such as a rubber tube. It is stretched horizontally.

Further, hooks 6 as fastening members are attached to both ends of each elastic string 5, and the hooks 6 on both sides are located outwardly on both sides of the sheet 1 in the longitudinal direction of the sheet 1. The elastic belt g in the presser side conveyor b shown in FIG. 1 is thereby configured.

According to the present invention, mounting strips that are approximately the same width as the seat are placed at appropriate intervals in the longitudinal direction of the sheet, and mounting strips that are approximately the same width as the sheet are sewn to the seat with both ends of the strips aligned. Therefore, the cylindrical part that connects the elastic string and the sheet can be formed over almost the entire width of the sheet surface with a single sewing operation, and it can accurately hold down articles of different shapes and sizes. By doing so, it is possible to easily manufacture an elastic belt that does not cause poor conveyance or damage to articles.
