The slip sheet detection device comprises: a slip sheet (110) disposed between a printed sheet lot (PL1) and a next printed sheet lot (PL2) to perform a marking function, so as to divide the printed sheet lot (PL1) and the next printed sheet lot (PL2) from printed sheets arranged in a lot unit at a paper supply part (11) of a paper folding machine (10); a detection sensor (120) for detecting exposure of the slip sheet (110), when the printed sheet lot (PL1) is completely supplied to a paper folding part (12) from the paper supply part (11) by a feeding roller (15) and the slip sheet (110) is exposed above the next printed sheet lot (PL2); a controller (130) for receiving a signal, which is input from the detection sensor (120), to control an operation of a warning means (140), and providing the signal to a control part (13) of the paper folding machine (10); and the control part (13) for, when the signal of the controller (130) is input, closing a solenoid valve (16) of the feeding roller (15), so as to automatically stop the supply of a printed sheet to the paper folding part (12) from the paper supply part (11).

Description

Separator detection device for grounding machine

The present invention relates to an interleaving paper detecting device for a folding machine for preventing the printing paper from being mixed and grounded in the process of folding a printing paper (folding material) to produce a book, and more specifically, any one from the feeding section to the grounding section by a feeding roller. When the printing paper supply of the lot is completed and the slip sheet is exposed to the upper part of the next printing paper lot, the detection sensor detects the exposure and the warning light and buzzer of the warning means operate, and the operation of the feeding roller is controlled to ground the paper feeder. It relates to an interleaving paper detecting device for a folding machine that automatically stops the supply of printing paper to the buro.

In the Republic of Korea Patent No. 10-1841746 (registered on March 19, 2018), "the folding method of the folding book that is applied to the folding folding machine and the folding book manufacturing apparatus" is introduced.

The folding folding method applied to the round folding machine and the folding booklet manufacturing apparatus is based on the first folding line parallel to the horizontal direction so that the upper end of the printing paper is positioned at the center of the printing paper in the state where one printing paper is unfolded. A first grounding step; A second folding step of folding the paper so that the paper is flipped on the basis of the second folding line parallel to the horizontal direction so that the lower end of the printing paper is in the center of the printing paper in the state of passing through the first folding step; At the same time, a pair of mislead lines are formed in a vertical direction with a predetermined width on the printing paper grounded by the second grounding step, and at the same width intervals preset on the left and right sides of the printing paper based on the misalignment lines. A third grounding step of forming a left vertical fold line and a right vertical fold line; A fourth folding step of sequentially folding a left vertical folding line parallel to the vertical direction on the left side of the printing paper to the pair of drawing lines sequentially based on a pair of the five lines formed by the third folding step; In the state of passing through the fourth folding step, the entire printing paper is turned over to the right, so that the left side of the grounded printing paper is placed on the right side and the right side of the printing paper is placed on the left side, and then the right vertical folding line parallel to the vertical direction A fifth folding step of folding in a clockwise direction so that the entire left side of the printing paper is covered with reference to and then folding in a counterclockwise direction based on the right vertical fold line; And a sixth grounding step of folding the left and right ends of the printing paper grounded by the fifth grounding step based on a pair of line of sight lines.

However, in a conventional round folding machine applied to the folding method of the folding booklet as described above, 1 lot of printing paper (generally referred to as large) is folded, and the same content is folded into a printed unit of printed paper) When trying to fold the next lot of printing paper, it is not possible to distinguish it automatically, and because the operator manually classifies it, there is a very high risk that the next lot of printing paper may be mixed with the printing paper of the previous lot. It was high.

Accordingly, an object of the present invention is to place a sheet of paper between one lot of printing paper and the next lot of printing paper, and supplying one sheet of printing paper from the feeding section to the grounding section by a feeding roller is completed, so that the sheet of paper is the next printing paper lot. When exposed to the upper part, the detection sensor detects the exposure, the warning light and the buzzer of the warning means operate, the feeding roller is controlled, and the supply of printing paper from the paper feed unit to the ground is automatically stopped. It is to provide an interleaving paper detecting device for a grounding machine that can not only allow an operator to recognize that a lot of printing paper is grounded, but also to prevent mixing of a printing paper of the next lot into a printing paper of a preceding lot.

The paper separator detecting device for a folding machine according to the present invention for achieving the above object, in order to distinguish one printing paper lot from the next printing paper lot in a printing paper arranged in lot units of the paper feeder of the folding machine, one printing paper A separator sheet disposed between the lot and the next lot of printing paper to serve as a marker;

When a lot of printing paper is supplied from the paper feed unit to the ground by the feeding roller, and the sheet is exposed to the top of the next lot of printing paper, the exposed sheet is detected, and it may be either a light sensor or a photosensor, When the lamp of the case is in a normal turn-on state, and detecting the sexagenary cycle, the lamp of the case is turned on, and a detection sensor providing a detection signal to the controller;

A controller that receives a signal from the detection sensor, controls the operation of the warning means, and provides a signal to a controller of the grounding machine;

When the controller signal is input, the solenoid valve of the feeding roller is closed, and it is characterized by comprising a control unit of a folding machine that automatically stops the supply of printing paper from the feeding unit to the grounding unit.

The folding machine may be either a round folding machine or a stand table folding machine.

The warning means is composed of a warning light and a buzzer, it characterized in that the operation is controlled by the controller.

Thereby, the interleaving paper detecting device for a folding machine according to the present invention can not only recognize that the ground of the printing paper of one lot is completed by the warning means, but also prevents the printing paper of the next lot from being mixed with the printing paper of the preceding lot. There is an effect that can be done.
