Device for detecting and conveying a plurality of materials and working method thereof

Abstract

The invention relates to a device for detecting and conveying a plurality of materials, which comprises an adjusting rod, a connecting plate, a long spring, a fixed plate, a proximity switch, a positioning screw, a nut, an adjusting plate, a roller, a positioning plate, a guide component, an adjusting screw, an adjusting nut, a seat, an elastic mechanism, a connecting shaft and a locking nut; andthe working method comprises the following steps of: adjusting the up-and-down position of the roller; adjusting the detection distance of a detecting electric eye and the upper plane of the connecting shaft; adjusting the height of the positioning screw; enabling materials to pass successfully when the detection distance of the detecting electric eye of the proximity switch and the upper plane of the connecting shaft is within the range of a set value; and sending out a signal when the detection distance of the detecting electric eye of the proximity switch and the upper plane of the connecting shaft is smaller than a set numerical value, and stopping conveying the materials. The invention has the following advantages that: parts have simple structure and are easy to process; the detection sensitivity is high; the adjustment is convenient, and the operation is easy; the surfaces of the processing materials are protected to successfully pass through detection without being scratched; and the detection range of the thickness of the processing materials is wider.

Description

(1) Technical field: [0001] The invention is suitable for a printing machine, especially for printing equipment required for sheet-sheet conveying, that is, a device for detecting and conveying multiple sheets of material and its working method. (two) background technology: [0002] The equipment for conveying single-sheet materials in the printing machinery currently used in the market needs to install a mechanism for detecting multiple sheets. [0003] A plurality of detecting mechanisms widely used in the prior art is a swing rod device (see figure 2 ). The sheet material passes through the roller (2-12), and it swings upwards with the swing rod shaft (2-9) as the axis center. Swing, if a single sheet of material passes through the roller, it is easy to scratch the printed surface of the material if it is tilted; multiple sheets of material swing upward through the side of the swing rod roller because the height of the roller (2-12) and the detection wheel exceed the th...

AI Technical Summary

Problems solved by technology

When adjusting the contact distance between the roller (2-12) and the detection wheel (2-14), the accuracy of the line contact is not high, and the structure of the connecting rod (2-1) and the fixing seat (2-5) is complicated. High precision requirements, difficult processing, cumulative error and its overall structure lead to low detection sensitivity, and the applicable processing material thickness range is small (0.1mm-4mm)
