Transfer mechanism for coil

Abstract

The invention relates to the technical field of cast film production equipment, in particular to a roll transfer mechanism which comprises a conveying line, on-line equipment and off-line equipment, the conveying line comprises a conveying line on-line section and a conveying line off-line section, the on-line equipment is arranged below the conveying line on-line section, and the off-line equipment is arranged below the conveying line off-line section. The conveying line comprises a track, a power chain and a plurality of transfer devices arranged at equal intervals, each transfer device comprises a trailer and a hanging frame, the trailers are slidably connected with the track and fixedly connected with the power chain, the hanging frames are hinged to the trailers, the hanging frames can rotate, and the hanging frames at least can rotate to be parallel to the horizontal plane. The hanging frame comprises a first form and a second form, and the maximum sectional area of the hanging frame in the first form is smaller than that of the hanging frame in the second form. The floor height of a plant can be fully utilized, packaged coiled materials are conveyed to a stacking machine from a production line with the minimum occupied area, and the space utilization rate of the plant is effectively increased.

Description

technical field [0001] The invention relates to the technical field of cast film production equipment, in particular to a roll transfer mechanism. Background technique [0002] Cast film is a non-stretched, non-oriented flat extrusion film produced by melt casting and quenching. There are two ways of single-layer salivation and multi-layer co-extrusion salivation. Compared with blown film, it is characterized by fast production speed, high output, and excellent transparency, gloss, and thickness uniformity of the film. [0003] The cast film production line in the prior art usually arranges several production lines facing each other when laying out the factory building, and sets a transmission line between the end points of several oppositely arranged production lines, and sets a station at the intersection of the end point of the production line and the production line for transfer. , the prior art has the following defects: 1. The transmission lines of the prior art are ...

[0003] The cast film production line in the prior art usually arranges several production lines facing each other when laying out the factory building, and sets a transmission line between the end points of several oppositely arranged production lines, and sets a station at the intersection of the end point of the production line and the production line for transfer. , the prior art has the following defects: 1. The transmission lines of the prior art are mostly belt or chain transmission lines. When the production line is running, the personnel on the station need to bypass the transmission line if they go to the other end On the one hand, it caused a lot of inconvenience to the staff; 2. The transfer of finished rolls from the production line to the transmission line requires manual transfer. Even if a robot arm is installed for transfer, the cost of installing a robot arm at each intersection is extremely high; 3. When the finished roll is transported to the designated position on the conveyor line, it can only be transferred manually or with a mechanical arm by setting up a station, which is also expensive; 4. The finished roll itself is not large in size, but it is used for belts or chains. Based on practical considerations, the conventional conveyor line can only dump the finished rolls before transshipment, which makes the width of the conveyor line at least equal to the length of the finished rolls, which takes up a huge area of ​​the factory when transferring ultra-wide finished rolls
