Section acceleration device of high-speed roller type automatic assembling machine and assembling machine

Abstract

The invention relates to the technical field of book assembling machines, in particular relates to a section acceleration device of a high-speed roller type automatic assembling machine and an assembling machine. The section acceleration device of the high-speed roller type automatic assembling machine comprises a fixed rod of which two ends are both fixed on a main rack of the assembling machine, wherein a hollow shaft is sleeved on the fixed rod; sliding blocks matched with the fixed rod are arranged at two tail ends of the hollow shaft; an acceleration hopper arrangement piece is fixedly connected to the hollow shaft; an acceleration hopper is arranged on the acceleration hopper arrangement piece; a sliding seat is fixedly arranged on the hollow shaft; the sliding seat is connected with one end of a right-angle swing arm through a first connecting rod; the right-angle swing arm is arranged on the main rack of the assembling machine through a movable bearing, and the other end of the right-angle swing arm is connected with a sleeve ring through a second connecting rod; and an eccentric wheel is movably matched in the sleeve ring and fixed to a main transmission shaft of a page carrying device. The problem that the high-speed assembling machine discharges sections disorderly is well solved, and the assembling work can be performed normally.

Description

technical field [0001] The invention relates to the technical field of book collating machines, in particular to a signature acceleration device of a high-speed roller-type automatic collating machine and a collating machine thereof. Background technique [0002] The roller type automatic collating machine is a professional post-press processing equipment that stacks single sheets of paper or signatures completed by previous processes into book blocks in the order of page numbers through the jaw roller mechanism. Compared with other collation methods, the roller collating machine has a compact structure, stable operation and high production efficiency, and is the mainstream of the collating machines in the post-press market at present; the working principle of the roller collating machine is shown in the attached manual picture figure 1 As shown, the signatures 105 to be collated are firstly stacked in the stacking bucket 104 of the corresponding station according to the or...

Problems solved by technology

[0004]However, due to structural limitations, the existing collating machines can only be used in environments with low operating speeds. When the collating machines operate in high-speed operating environments, If the running speed is greater than 10000c / h, when the matching bookmarks fall into the conveying channel with the high-speed rotation of the gripper wheel, they will inevitably collide with the conveying channel, especially when the signature paper is thick and heavy, it may even appear. Rebounding, skewing and other phenomena, in serious cases, will also cause blockage of the conveying channel due to the flipping of the signature; and when the signature paper is light and thin, especially for single-sheet paper, the gripping wheel will drop the signature due to air resistance when it falls at high speed. The signature is skewed or even floated so that it cannot fall into the designated position; even if the signature is placed accurately, because the speed of the signature in the conveying channel is zero, and the following lever hits the signature at high speed, it may It will cause the signatures to be skewed or even bounced off, making the book block conveyance difficult. In severe cases, the signatures will be overturned and the conveying channel will be blocked, resulting in a high failure rate of the high-speed collating machine, which is not conducive to production.
