Stamping and shearing processes in the manufacturing industry require the use of coil materials to achieve automated production. Material racks have become specialized equipment for carrying coil material, and among various types of coil carrying equipment, the decoiler has become the mainstream material release uncoiling equipment due to its advantages of large carrying capacity, wide applicability of material thickness and width ranges, and customizable options.
The standard type decoiler is an induction rack type that has some inevitable defects. To address these issues, Henli has developed and produced a photoelectric control decoiler that replaces the induction rack with multiple sets of photoelectric switches for control. This article explores the benefits of using the photoelectric control decoiler.
More Precise Control
The basic principle of the standard type decoiler is that when the decoiler uncoils and feeds the metal coil into the subsequent leveling machine, the material sag caused by the gravity of the metal material will occur during the transmission process. The contact with the induction rack will control the material rack to stop, and the decoiler will automatically run after it leaves to achieve fully automated control of the material rack.
However, the uncoiling speed of the decoiler affects the sag height of the material rack, which can cause loose or uncoiling phenomena. The standard type decoiler is also limited to metal materials. The material rack can be stretched straight and cause roll forming, which can lead to material rack stretching, deformation, and even damage, and both the leveling machine and the decoiler can be damaged during the stretching process.
Henli’s photoelectric control decoiler has multiple sets of photoelectric switches that sense the sag height of the material rack and control the rotation speed of the decoiler rotating axis according to the changes in the sag height. This results in precise control of the decoiler, fundamentally solving the occurrence of roll forming and uncoiling phenomena of the material rack and improving the efficiency of stamping production.
The photoelectric control decoiler is a new type of uncoiling equipment that is mainly used on the three-in-one feeder. It consists of three sets of vertically arranged photoelectric switches, which are connected to the frequency converter in the material rack control box to control the speed. When the reliable quality photoelectric switch senses the material, it indicates that the uncoiling speed of the decoiler is too slow. The controller drives the decoiler to increase the uncoiling speed to prevent roll forming and damage to the material rack.
When the second set of photoelectric switches senses the material, it indicates that the uncoiling speed of the decoiler is too fast. The frequency converter drives the decoiler to slow down the uncoiling speed to prevent loose uncoiling. The third set of photoelectric switches senses and controls the stop of the material rack, fully realizing automated and precise control.
Henli’s photoelectric control decoiler also offers customizable options to meet different manufacturing needs. The equipment can be tailored to fit specific material thickness and width ranges, making it a versatile option for various stamping and shearing processes.
The photoelectric control decoiler developed by Henli offers improved efficiency, automation, and versatility in stamping and shearing processes. By replacing the induction rack with photoelectric switches, the decoiler achieves precise control and eliminates the occurrence of roll forming and uncoiling phenomena of the material rack. Customizable options also make it a versatile option for different manufacturing needs.
