A software limit control method for sponge ring knife cutting machine cutting

Abstract

The invention relates to a software limit control method when a sponge ring knife cutting machine cuts. The steps are: shift the ring knife to the leftmost position of the sponge cutting machine, that is, position 0, and save the position information; move the ring knife to Position to the far right of the sponge cutting machine, and save the position information; when shifting normally, record the current position of the ring knife and the information of the saved positions on both sides, automatically calculate the maximum position and maximum speed that the ring knife can move, and carry out Acceleration and deceleration movement, if it exceeds the range, it will prompt and stop moving; during processing, record the current position of the ring cutter and the information of the saved positions on both sides, compare it with the processing range, if it exceeds the range, it will prompt and stop processing. The present invention has the advantages of: first record the maximum distance between the two ends of the sponge cutting machine through the servo motor, and then calculate the movable maximum position and maximum speed of the ring knife according to the position of the ring knife during cutting, thereby avoiding the excessive cutting of the ring knife. In case of mechanical damage.

Description

technical field [0001] The invention relates to a software limit control method during cutting by a sponge ring cutter cutting machine. Background technique [0002] For the current machines with faster displacement, we take the sponge ring cutter cutting machine as an example. When cutting sponge, because the cutting speed is faster, the transmission speed of each axis is faster. The general practice is to use electrical limiters for each axis Position switches and mechanical hard limit devices are used for single or double limit to avoid damage to equipment caused by overtravel. [0003] However, once the movement speed is too fast, when each axis touches the electrical limit switch or the mechanical limit switch, a certain reaction process is required. At this time, the actual state has already exceeded the travel, and the actual mechanical damage has been caused. . Contents of the invention [0004] The technical problem to be solved by the present invention is to pr...
