Winding packaging machine for automatic coiled material packaging line

Abstract

The invention discloses a winding packaging machine for an automatic coiled material packaging line. The winding packaging machine comprises a fixing frame, a coil library, an annular track, a rotary ground roller, a coiled material inner hole inspection device and a control system, wherein the winding trolley is used for winding a packaging material on a coiled material, the coil library is used for storing at least two packaging materials and supplementing the packaging material to the winding trolley, the annular track is arranged on the fixing frame and is used for guiding the winding trolley to run, the rotary ground roller is used for driving the coiled material to rotate. Provided are a coiled material inner hole inspection device and a control system. According to the winding packaging machine for the automatic coiled material packaging line, through cooperation of the winding trolley, the annular track and the coil library, winding of packaging materials on coiled materials can be achieved, and the packaging efficiency of the coiled materials is improved; before each time of winding and packaging, the coiled material inner hole inspection device checks, analyzes and judges whether a coiled material inner hole meets the winding and packaging conditions or not, and collision accidents of the winding trolley are effectively prevented; and the winding trolley is automatically supplemented with packaging materials through the coil library, the manual intervention frequency can be reduced, and the automation degree is high.

Description

technical field [0001] The invention belongs to the technical field of coil packaging equipment, in particular, the invention relates to a winding packaging machine for an automatic coil packaging line. Background technique [0002] Cold-rolled sheets in the iron and steel industry or cold-rolled aluminum sheets in the aluminum industry are generally 0.15 to 3mm thick. Products produced by similar companies are mostly delivered in coils, called steel coils or aluminum coils, which are collectively referred to as coils below. Generally, the inner hole of the material is φ508 or φ610mm, the outer diameter is φ700~φ2400mm, and the width is 800~2200mm. In order to ensure that the coil will not be rusted and damaged before delivery, the coil will be packaged, including the inner layer of anti-rust packaging and the outer layer of mechanical protection packaging. The inner layer of anti-rust packaging mainly refers to the installation of anti-rust paper or film. For the inner la...

Problems solved by technology

[0004] 1. The core problem of the tension of the packaging material has not been solved: the force on the packaging material at different points of winding is completely different. Some places have tension, while others do not. The prior art packaging equipment uses springs ( or gas spring) type of energy storage mechanism can theoretically solve the above problems, but in actual operation, frequent packaging material breaks will be caused by reasons such as operating speed and packaging material performance. Therefore, the performance requirements for packaging materials are relatively high. It is necessary to use the supporting imported stretch film. If the domestic stretch film is used, the probability of film breakage is high, which will affect the packaging efficiency

[0005] 2. Due to the problem of tension control, the packaging equipment in the prior art has no way to pack different packaging materials at the same time, and generally can only be used for packaging stretch stretch film

[0006] 3. The inner hole of the coil is not supported by any object (unlike a cardboard tube in the commonly used paper roll), it is very likely that the innermost circle will collapse (called inner hole collapse), and there is no detection system In some cases, collision accidents between the track or the shuttle and the collapsed part are likely to occur. The existing method is to install opposite-beam photoelectric sensors at the top and bottom of the inner hole with a diameter of 508mm, but there is a high probability that the edge will collapse but it can be avoided. The light condition of the beam photoelectric sensor makes the beam photoelectric sensor unable to detect effectively;

[0007] 4. The existing winding packaging machine is equipped with a shuttle replacement mechanism, which supplements the packaging materials by using a section of guide rail to guide the same row of shuttle cars to replace the shuttle cars that have run out of packaging materials. Manual intervention is required for each replacement , affecting packaging efficiency
