As shown in fig. 6, the present invention provides a collating machine including a gripper 203, a conveying path 102, and a feeding device, the feeding device being located below the gripper 203.

As shown in fig. 4, in the automatic collating machine of the present invention, the signatures 105 to be collated are stacked in the stacking hoppers 104 of the corresponding stations in sequence according to page numbers, a roller type gripper mechanism is installed under each station, when the machine is operated, the gripper mechanism holds the lowest signature of the signatures 105 to be collated out and puts the lowest signature on the conveying channel 102, then the poking rod 103 pushes the signatures on the conveying channel 102 to move forward along with the conveying chain 101 to enter the next station, and the gripper mechanism of the next station performs the same gripper feeding action to stack the signatures to be collated of the next page on the previous signature; this is followed by stacking of all stations to form a booklet signature 106.

As shown in fig. 5, a specific working process of the automatic collating machine according to the present invention includes: five stages of suction, paging, gripper, falling and conveying; the suction stage is a process of sucking and pulling down the lowest signature of the signature stack 201 to be matched from the page storage table by using a swingable suction nozzle with adsorption capability; the paging stage and the suction stage are synchronously carried out, when the suction nozzle sucks the lower hem of the signature 202, the paging hook is lifted oppositely to the movement direction of the suction nozzle, and the sucked signature 202 is just lifted up to a to-be-matched signature stack 201 on the page storage table when the suction nozzle swings to the highest point, so that the next signature is prevented from being adhered to the lower part to generate double lower signatures; the gripper stage is that after the suction nozzle sucks and swings to the lowest point, the suction nozzle loosens the gripper 202, and simultaneously, the gripper wheel of the gripper device 203 rotating forwards drives the gripper to clamp the gripper 202 to continue to do circular motion; the doffing stage is a process in which the grippers are clamped to the signature 202 from a clamping state when the signature 202 moves above the conveying passage 103, and gradually unclamped from the clamping state to the signature 202, and the signature 202 falls into the conveying passage 103; the conveying stage is that the matched signature 202 after falling into the conveying channel 103 moves along the conveying channel 102 under the pushing of the book poking rod 103.

The paste feeding device has the structural advantages that:

(1) Most of the existing collating machines have the defects that after the gripper loosens the signature, the signature is in a short-time flying state and flies into the book drop hopper, the signature is greatly influenced by airflow in the moving process, particularly, the thinner and lighter signature is easy to float out of the book drop hopper or cannot fall to the appointed position of the book drop hopper, and moreover, when the machine is in a low-speed state, the gripper wheel rotating speed is lower, and the inertia of the signature is smaller, so that the signature cannot fall to the appointed position in the appointed time; the signature feeding device of the books clamps the signatures by using two pairs of clamping belts and then feeds the signatures into the book drop hopper 601, so that the signatures can accurately and stably slide into the appointed position of the book drop hopper 601 within the appointed time without being influenced by air flow and speed; the feeding device can greatly reduce the unstable influence of air flow on the signature when the signature is fed at a high speed;

(2) The invention can greatly improve the adverse effect generated by the high-speed impact of the book poking rod 103 on the signature; after the signature falls into the hopper 601, the speed is zero in the travelling direction of the conveying channel 102, and the follow-up book poking rod 103 impacts the signature at a high speed, so that the signature can be skewed or even flicked to cause the non-smooth conveying of the book block, and the signature can be knocked over to block the conveying channel in severe cases; after the signature falls into the hopper 601, the signature feeding device of the invention dials the signature into the conveying channel 102 by the book poking rod 103 after an acceleration link is given to the signature, the signature has a certain speed in the advancing direction of the conveying channel 102, the force of the poking rod 103 contacting the signature is reduced, and the signature stably moves along with the book poking rod 103.

(3) The feeding device can improve irregular rebound phenomenon generated when the signature falls into the hopper 601; during the rebound of the signature, the accelerating platen 314 presses the signature, giving a force to the signature in the traveling direction of the conveying path 102, and the front portion of the upper paper guide plate 323 is designed to be concave, and the rebound signature is restrained in the groove and kept in a regular state.

(4) The upper part of the channel of the feeding device can be turned up, so that the channel blockage can be conveniently cleaned, the long guide seat 318 and the short guide seat 319 can rotate and swing around the driving pulley shaft 401, and the turning up and the falling down of the acceleration pressing plate 314, the lower end of the clamping belt, the upper paper guide plate 323 and the lower paper guide plate 501 are realized through the extension and the contraction of the air cylinder 324 at the shaft end of the accelerator mounting shaft 317.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
