Embodiment Construction

[0010] Now, the present invention will be further described through specific embodiments.

[0011] The preferred rubber double cam feed control method of the present invention comprises the following steps:

[0012] (1) Set the change height of the rubber curve feed through the PLC controller to control the rubber curve feeding device so that the stretching degree of the rubber band can adapt to the stretching degree required by the corresponding rubber band of different products. The elastic curve feeding device includes a first motion controller, a second motion controller, a first servo motor, a second servo motor, a rubber feeding and pressing wheel set and a swing bar, and the first motion controller is controlled by a servo The motor is connected to and controls the swing of the pendulum, and the swing of the pendulum drives the rubber band to carry out curved conveying and feeding. The second motion controller is connected to the second servo motor and controls the rubb...

Abstract

The invention relates to the field of sanitary article manufacturing, and provides a rubber band double-cam feeding control method. The method comprises the following steps that (1) a rubber band curve feeding device controlled by a PLC is arranged to adjust the changing height of rubber band curve feeding, so that the stretching degree of a rubber band adapts to the stretching degree required byrubber bands corresponding to different products respectively; and (2) the PLC controls a first motion controller, then the first motion controller controls and adjusts the forward and reverse rotation angle of a first servo motor to adjust and control the swing angle of a swing rod, meanwhile, the PLC controls a second motion controller according to a rubber band curve feeding graph, the swing speed of the swing rod and the rubber band conveying rate, and the second motion controller controls the operation speed of a second servo motor to guarantee the rubber band output speed. The method solves the problems that the rubber band rate of existing rubber band curve feeding cannot be effectively controlled and the changing rate of the rubber bands cannot be changed in real time to adapt to production switching of various products.

Description

technical field [0001] The invention relates to the technical field of hygienic product manufacturing, in particular to a method for controlling feed of elastic double cams. Background technique [0002] As consumers have increasingly strict requirements on product quality and product appearance. In the production process of automatic production lines such as diapers, pull-up pants, adult diapers, etc., due to the need to achieve more three-dimensional products, more beautiful product appearance, and the need for ergonomic design to improve the comfort of the product, so the rubber band The need for curve feed was born. However, due to problems such as motor characteristics, load inertia, and curve shape control, it has always been a major problem for many manufacturers to realize high-speed feeding of elastic curves. Some manufacturers directly make a set of mechanical cams according to the elastic curve, but the mechanical cam cannot solve the problem of high and low spe...
