Roll flipping machine is a mechanical equipment used for handling and rotating rolls, widely used in the industrial field.

Functional purpose:

The roll material flipping machine is mainly used to flip materials from the vertical direction to the horizontal direction, or from the horizontal direction to the vertical direction. For example, in the processing of food film rolls, it can first receive a pallet with rolls using a forklift, then flip the rolls 90 ° and place them on an electric moving prism with lateral movement function for subsequent handling through an overhead crane.

Structural features:

Taking a certain electric Coil Flipping Machine as an example, it is completely driven by electricity, avoiding the problem of hydraulic leakage, and is easy to assemble and transport. It can be moved by forklift. This device does not require a closed enclosure and is equipped with all necessary safety components such as sound warning devices, a complete sensor system, emergency mushroom buttons, etc. It has been certified by authoritative institutions.

Operation method:

The electrical connection of the roll material flipping machine can be made through a standard 220V single-phase socket and grounding connection. Control is integrated through the button box on the machine, allowing operators to semi automatically or manually control the equipment.

Application fields:

The Steel coil flipping machine is a sturdy and efficient machine designed for safe handling and rotation of steel coils, making it ideal for industrial environments such as steel mills, metal processing workshops, etc. It can improve operational efficiency, reduce manual labor, and minimize workplace risks to the greatest extent possible.

Selection considerations:

When purchasing a roll material flipping machine, price is a key consideration factor, but at the same time, equipment capacity, customization functions, etc. should also be taken into account. The price difference of roll flipping machines with different capacities is significant. The larger the capacity, the greater the weight and size of the rolls that can be processed, and the higher the price. In addition, roll flipping machines with functions such as automation control, safety mechanisms, and energy efficiency upgrades, although expensive, can significantly reduce labor costs and improve productivity.

The core working principle of the roll material flipping machine is to drive the clamping and positioning mechanism through the power drive system, stably rotate the roll material according to the preset trajectory, and achieve the transformation of its posture from "horizontal → vertical" or "vertical → horizontal". At the same time, the safety control system ensures that the roll material does not deviate or fall during the operation process, ultimately meeting the transportation, processing or storage needs of subsequent production processes. The workflow can be broken down into four core steps: "clamping and fixing → power driven flipping → positioning in place → release and transfer".

Workflow (taking "vertical coil → horizontal coil" as an example)

Taking the scenario of processing steel coils in a steel plant as an example, the complete working steps of the coil flipping machine are as follows:

Loading and positioning: The forklift transports the vertically placed steel coil to the flipping frame of the flipping machine. The positioning sensor detects whether the steel coil is centered. If it is offset, it is fine tuned through the clamping arm to ensure that the center of gravity of the steel coil is aligned with the rotation axis of the flipping frame.

Clamping fixation: The operator activates the clamping function through the control panel, and the clamping arm slowly tightens until the buffer pad is tightly attached to the surface of the steel coil. The pressure sensor feedback clamping force reaches the rated value, and the clamping system is locked.

Power driven flipping: Activate the flipping command, and the power system drives the flipping frame to slowly rotate around the horizontal rotation axis; During the rotation process, the control system monitors the flipping angle in real time and provides feedback on the position information through the encoder.

In place locking: When the flipping frame rotates to 90 °, the limit switch is triggered, the power system is powered off, and the flipping frame is fixed by a mechanical locking mechanism to prevent accidental rotation.

Release and transfer: The clamping system releases the clamping arm, and the operator transfers the horizontal steel coil to the next process through the overhead crane or roller conveyor, completing one flipping cycle; Subsequently, the flipping frame rotates in the opposite direction to reset and prepare for the processing of the next roll.

The principle differences of different types of roll flipping machines

According to the power source and application scenario, the roll material flipping machine can be divided into hydraulic, electric, and semi-automatic types, with detailed differences in their working principles, suitable for rolls of different weights:

Hydraulic coil flipping machine: using hydraulic oil as the power medium, transmitting power through hydraulic pumps and cylinders, with large flipping torque, smooth flipping process without impact, suitable for heavy-duty metal coils; The disadvantage is that it requires regular maintenance of the hydraulic system to avoid oil leakage.

Electric coil flipping machine: driven by servo motor or reduction motor, through gear/chain transmission, with high flipping accuracy and no need for hydraulic oil, clean and environmentally friendly, suitable for lightweight coil materials; The advantages are simple operation and low maintenance costs.

Semi automatic coil flipping machine: Some steps require manual assistance, and the power system only provides flipping power, suitable for small batch and multi specification coil processing scenarios. The cost is lower, but the efficiency is lower than that of fully automatic models.

Core design principles: balance of center of gravity and control of force

The safety and stability of the roll material flipping machine essentially rely on two design principles: "center of gravity balance" and "precise control of force":

Principle of center of gravity balance: During the flipping process, the center of gravity of the coil must always be within the support range of the flipping frame, otherwise it may cause the flipping frame to tilt or the coil to fall. Therefore, during equipment design, the rotation axis position will be calculated and fixed based on the maximum diameter and weight of the target coil, ensuring that the center of gravity does not shift when flipping coils of different specifications.

The principle of force control: The clamping force should be "moderate" - too small will cause the coil to slide, and too large will crush the coil. Therefore, modern flipping machines often adopt "pressure closed-loop control": pressure sensors provide real-time feedback on clamping force, and the control system automatically adjusts the clamping arm pressure based on the material of the coil, achieving "flexible clamping".

In summary, the working principle of the coil flipping machine is a combination of "mechanical structure+power drive+intelligent control". The core goal is to efficiently and accurately complete the coil posture conversion while ensuring safety, and adapt to the coil processing needs of different processes in industrial production.
