AI Technical Summary

Technical Problem

In existing technologies, uncontrolled movement can easily occur during the transmission of single sheets, making it difficult to achieve accurate and safe transmission. In particular, when receiving and transferring single sheets from other sheet feeding mechanisms, there are complex installation and adjustment problems.

Method used

Design a roller with an air suction opening. By rotating the through-part to apply low pressure, the position and size of the suction opening can be changed at a specific rotation phase. Combined with magnetism and suction elements, it can achieve precise holding and conveying of single sheets of paper.

Benefits of technology

It achieves precise and secure sheet delivery, optimizes the delivery process, simplifies roller installation and adjustment, and is suitable for generating optical variable primitives.

Abstract

The present invention relates to a roller (26; 17; 152; 12) of a machine (01) for processing and / or handling single sheets of paper, the roller including a holding mechanism (33) on its circumference, wherein a substrate single sheet (02) to be fed on the roller (26; 17; 152; 12) is received by the holding mechanism at its front end, and is held or can be held during rotation of the roller (26; 17; 152; 12) within an angular range between the receiving portion of the substrate single sheet (02) and its downstream feeding portion, and the roller having a rotational through portion (123) including: a rotor (124) rotating together with the roller (26; 17; 152; 12), the rotor being torsionally arranged at the end side to drive the roller (26; 17; 152; 12) at the end side. On the side of the shaft (32) of the roller (26;17;152;12) or on the roller journal (128) arranged on the end side; and a stator (126) that does not rotate according to the operation, wherein the suction opening (42) or the group of suction openings (42) provided on the circumference of the roller (26;17;152;12) can be loaded with low pressure during the effective angular phase of the roller (26;17;152;12) about its axis of rotation (R), wherein the rotation through part (123) can be adjusted in terms of the size of the through angle sector (Δφ) that determines the size of the effective angular phase and / or the position of the through angle sector (Δφ) that determines the position of the effective angular phase.
