Embroidery machine power-off protection method and system

Abstract

The invention discloses an embroidery machine power-off protection method and system, and belongs to the technical field of computerized embroidery machines. The method comprises the following steps that during power failure, if a main shaft is in a rotating trend away from a zero position, power supplying to a main shaft driving mechanism is stopped, and the main shaft is made to continuously rotate with inertia along the direction during power failure until the main shaft is stopped; when the main shaft stops, if the main shaft is in the rotating trend away from the zero position, the main shaft is made to rotate reversely, and power is supplied to the main shaft driving mechanism till the main shaft returns to the zero position; if the main shaft is in the rotating trend close to the zero position, power is supplied to a main shaft driving mechanism, and the main shaft is made to continuously rotate to the zero position along the direction during power failure; and during power failure, if the main shaft is in the rotating trend close to the zero position, power is continuously supplied to the main shaft driving mechanism, so that the main shaft continuously rotates along the direction during power failure until the main shaft returns to the zero position. The main shaft of the embroidery machine can be effectively ensured to return to the parking space during power failure, the restarting efficiency is improved, additional component cost does not need to be increased, and the economic benefit is high.

Description

technical field [0001] The invention relates to the technical field of computerized embroidery machines, in particular to a power-off protection method and system for an embroidery machine. Background technique [0002] At present, the embroidery machines on the market generally do not perform special treatment when the power grid fails, and the machine is in a state of natural power failure and shutdown. At this time, the parking position of the spindle is uncertain. At present, due to the mechanical design of the embroidery machine, if the main shaft of the machine is not at the zero position when it is powered on again, the equipment will not be able to operate and needs to return to the parking space. If the machine is forced to operate, the machine may be damaged. At this time, it is necessary to manually turn the main shaft to the zero position to perform the next operation, which greatly reduces the work efficiency. For areas with frequent power outages, such as some...

Problems solved by technology

At present, due to the mechanical design of the embroidery machine, if the main shaft of the machine is not at the zero position when it is powered on again, the equipment will not be able to operate and needs to return to the parking space

If the machine is forced to operate, it may damage the machine. At this time, it is necessary to manually turn the main shaft to the zero position to proceed to the next operation, which greatly reduces the work efficiency.

For areas with frequent power failures, such as some backward countries or regions such as Africa, the workload of operators will increase. If operators do not perform manual alignment without knowing it, they may misoperate the machine and cause damage to the machine.
