Horizontal roller suction collating machine

Abstract

The invention relates to the technical field of book collating machines, and discloses a horizontal roller suction collating machine. The horizontal roller suction collating machine comprises a base,paper, a conveying belt, a pneumatic pump and a hydraulic pump. By arranging center shafts and pressure sealing devices, the paper is integrally sucked; on the one hand, sufficient tension on the paper is provided, the harm of grippers to the paper is avoided, the safety of the paper is improved, the situation that the tail of the paper hits against the equipment in the rotating process of the center shafts is prevented, the damage of the paper is reduced, and the product quality is improved; and on the other hand, uninterrupted collating can be achieved, the outer surfaces of the pressure sealing devices are efficiently utilized, the collating speed is increased, and the collating efficiency is improved. Meanwhile, by arranging expanding devices, the diameter of the collating device is regulated and controlled, the diameter of the collating device can be selected according to the length of the paper, at least two pieces of paper can be collated when the collating device rotates by onecircle, and the collating efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of book collating machines, in particular to a horizontal roller suction collating machine. Background technique [0002] The collating machine is to match papers with different page numbers together. It can be divided into clamp type and roller type collating machine. The working principle of the roller type collating machine is as follows Figure 8 As shown: the rotating roller 1 rotates, and drives the suction nozzle 2 and the gripper 3 to rotate. When it rotates to the gap below the storage box 4, the cam installed on the rotating roller 1 controls the movement of the gripper 3. Open and close, clamp the paper 5, and then rotate again, carry the paper 5, turn to the page box 6, the suction nozzle 2 and the gripper 3 are separated, the paper 5 is released, and the page roller 7 is used to dial move to make the paper 5 return to its original position, but there are some deficiencies in this process, as fol...

Problems solved by technology

[0003] First, when the suction nozzle 2 and the gripper 3 are clamping the paper 5, because the cam drives the gripper 3 to rotate, which is a mechanical movement, the thickness of the paper 5 cannot be accurately measured, and the clamping force is prone to be too large , so that the paper 5 has an indentation, or the clamping force is too small to pull the paper 5 out, and then the phenomenon of page loss and paper jam occurs, and the gripper 3 is in the process of closing. The paper 5 at the gap causes local impact, which is easy to cause damage to the paper 4, resulting in a decline in product quality

[0004] Its two, because the diameter of rotary drum 1 is fixed, then can't adjust according to the length of paper 5, once the length of paper 5 exceeds half of the circumference of the section of rotary drum 1, then paper 5 covers another gripper 3, The speed of collating pages of the collating machine will be greatly reduced. At the same time, the constant diameter of the rotating roller 1 will greatly restrict the rotating speed of the rotating roller 1. If the speed is too high, the closing speed of the gripper teeth 3 will increase accordingly. If the speed is too high, the damage to the paper will be increased; if the speed is too slow, the paging speed will be affected

[0005] Third, when the paper 5 is transported to the page box 6, the paging roller 7 collides with the paper 5, which will easily cause creases to appear on the paper 5, further affecting the quality of the paper 5, and causing a decline in the quality of the product
