Embodiment

[0033] Step 1, such as figure 2 As shown, select commonly used different paper format specifications N 1 ~N 7 , the paper format includes the largest standard paper A1 format N 1 : 841mm*594mm, non-standard paper format N 2 : 640mm*536mm, standard paper A3 size N 3 : 420mm*297mm, A4 format N4: 297mm*210mm, positive degree 16 format N5: 270mm*185mm, positive degree 8 format N6: 390mm*270mm, positive degree 32 format N 7 : 185mm*135mm;

[0034] Step 2: Carry out the front gauge and left / right orientation of all specifications of paper in step 1. From step 1, it can be known that paper N 1 has an aspect ratio greater than Therefore choose paper N 1 right / left The location is the anchor point ( figure 2 Selected to the right The position is the anchor point); paper N 2 with an aspect ratio smaller than Therefore choose paper N 2 The middle position is the anchor point; the aspect ratio of paper N3 is equal to Therefore choose paper N 3 The middle position i...

Abstract

The invention discloses a sheet-fed positioning paper feeding board design method. The method comprises the following specific steps that 1, different paper breadth specifications are selected; 2, allthe paper breadths selected in the step 1 are subjected to front lay and left / right side lay positioning, the positioning point of each paper is selected according to the length-width ratio of the paper, and an arc for paper positioning is obtained by connecting the obtained positioning points; 3, the specification of a paper feeding board is determined; and 4, an arc-shaped lay positioning groove is formed on the paper feeding board of which the specification is determined in the step 3 according to the positioning arc obtained in the step 2, a paper positioning lay moves along the positioning groove, and then positioning of paper with different breadths is achieved. The problem that in the existing paper positioning mode, paper positioning deviations exist due to the fact that a paper feeding board is unreasonable in design is solved.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, and relates to a design method for a sheet-fed paper positioning feeding board. Background technique [0002] At present, in the case of collating business books and periodicals and printing documents by printers, it is necessary to place the paper on the paper feeding board to position the front, back and sides of the paper. This process is usually determined by the front and rear rules of the paper positioning feeding board and It is realized by the lateral positioning device. The prior art paper front, back and side positioning devices include a front plate installed on the front of the paper feeding board, a rear rule and a right end plate on the right. Due to the consideration that there will be papers of different sizes when matching business books and periodicals, and The existing paper positioning device cannot meet the positioning of paper of different sizes, which will cause...
