Section accelerating device of high-speed roller type automatic collating machine and collating machine of section accelerating device

Abstract

The invention discloses a section accelerating device of a high-speed roller type automatic collating machine and a collating machine of the section accelerating device. The section accelerating device of the high-speed roller type automatic collating machine comprises a base body and a rack and further comprises a page holding device, a conveying channel and a section accelerating device body; the base body is sleeved with two reduction gearboxes, and the input shaft ends of the two reduction gearboxes are both sleeved with belt wheels; the belt wheels are in transmission connection with a page holding main shaft through a belt; the output shaft ends of the two reduction gearboxes are each fixedly connected with a crank; the other ends of the cranks are movably connected with connecting plates; pressing blocks are vertically arranged on the connecting plates in a penetrating mode; the page holding device comprises the page holding main shaft, a page holding mechanism, a section feeding belt and an acceleration hopper, the page holding main shaft is rotationally connected with the rack, and the section feeding belt is in friction connection with the page holding main shaft. According to the section accelerating device of the high-speed roller type automatic collating machine, various impacts generated during high-speed section discharging are greatly reduced through the section acceleration device body; and falling sections have a certain horizontal relative speed and can be matched with a book shifting rod, so that a good accelerated conveying effect is achieved.

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. It is the mainstream of the collating machine in the post-press market at present; 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 order of the page numbers. A roller-type gripper mechanism is installed under each station. When th...

[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.
