Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in winding devices for sheet-like elastomeric articles.

The insulation interposed between the carcass plies of a sheet-like elastomeric article, such as a tire, has a width of, for example, 2
Conventionally, the insulation 3 is a thin rubber layer of 5 to 10,001 g and 0.3 to 1.2 g thick, and as shown in FIG. It hangs down from the terminal end of the conveyor 2 and transfers to the starting end of the receiving conveyor 4.
The liner 7 is then transported to a take-up roll 6 driven by a surface drive mechanism 5 and wound together with a liner 7, and cut at a predetermined winding diameter by a cutter mechanism 8 to wind up the rear end 3a.

However, when the insulation 3 is cut by the cutter mechanism 8, the rear end 3a falls onto the receiving conveyor 4 side and becomes wrinkled, or sticks together, making it necessary to scrap the insulation. There was a problem.

The present invention has been made in view of the above-mentioned conventional problems.
The first invention includes a drive conveyor that conveys sheet-like elastomer articles in one direction, a longitudinal carriage that can freely travel back and forth on longitudinal rails parallel to the drive conveyor, and a drive conveyor supported by the longitudinal carriage. A traverse carriage that can freely travel back and forth on a traverse rail perpendicular to the traverse rail, and a take-up roll that is supported by the traverse carriage and can freely move up and down and rotate during winding are provided. A tip winding mechanism for winding the tip of the elastomer article around the take-up roll is disposed, and a cutter mechanism capable of cutting the elastomer article before the take-up re-roll is disposed midway along the drive conveyor, and the cutter mechanism is positioned at the front position. The winding roll with the tip of the elastomer article wound thereon is brought into contact with a drive conveyor and co-rotated while winding up the elastomer article, and the elastomer article is moved vertically to an intermediate position on a longitudinal carriage, and the elastomer article is rolled at a predetermined winding diameter. Provided is a winding device for a sheet-like elastomer article, characterized in that after cutting and winding up the rear end, the article is moved sideways on a traversing cart and the receiver is transferred to a conveying means located on the side of a drive conveyor. In particular, the sheet-like elastomer article wound on the take-up roll can be completely wound on the take-up roll without wrinkles or sticking to each other at the trailing end of the cut sheet-like elastomer article. This allows the winding work of articles to be carried out fully automatically.

In addition, the second invention aims to improve the efficiency of the winding operation in the winding device according to the first invention, and is provided with two longitudinal carts, two transverse carts, and a winding roll, and This allows the work to be carried out fully automatically and continuously.
