A differential tracking buffer type anti-collision paper feed method

Abstract

The application provides a differential tracking buffer type anti-collision paper feeding method applied in a corrugated color box processing process, and the technical principle is as follows: 1, a speed difference between two groups of conveying belts running in the same direction but at different speeds is formed; 2, the suction belt is started to run into the box piece in the conveying bed standby position, so that the static box piece is moved; 3, the synchronous conveying belt is started to chase the box piece in the front when the box piece is in the moving state; 4, the positioning work push plate on the synchronous conveying belt chases the box piece in the front when the box piece is about to reach the first processing station; 5, because the speed of the synchronous conveying belt is slightly higher than that of the suction belt, the push plate of the synchronous conveying belt flexibly takes over the box piece running on the suction belt and continues to run forward; 6, the soft contact is formed by taking over and transferring the box piece in the moving state, so that the hard contact formed by the static and dynamic states in the high-speed moving state is avoided, and the collision is avoided.

Description

Technical Field

[0001] This invention relates to the field of paperboard processing technology, specifically to a differential speed tracking buffer-type anti-collision paper feeding method. Background Technology

[0002] In recent years, to address the environmental problem of white pollution caused by plastic handles on corrugated boxes, my country's corrugated packaging industry has developed non-woven fabric handles. However, the operation of non-woven fabric handles requires a push-plate synchronous conveyor belt for transporting the box sheets. Therefore, during high-speed operation, the plastic push plates on the synchronous conveyor belt inevitably cause significant impacts to the stationary corrugated box sheets on the conveyor bed, resulting in severe damage. Furthermore, fully automatic double-sheet gluing machines also use this principle for paper feeding. Thus, the damage caused by impacts has become a pressing problem for the industry. Currently, there is no reasonable and effective solution in the industry; the only temporary measure is to attach die-cut spring pads in front of the push plates for cushioning. However, due to the high impact force, each application of spring pads only lasts for two hours. Additionally, the thickness of the die-cut spring pads and the thickness variations caused by impacts result in serious errors in the handle's positional accuracy. Furthermore, the frequent and time-consuming application of spring pads increases production costs. Summary of the Invention

[0003] In view of this, the present invention provides a differential tracking buffer anti-collision paper feeding method, which utilizes the differential principle between different speeds to change hard contact into soft contact by using a fast speed to catch up with a slow speed, thereby avoiding impact damage to the corrugated box sheets caused by the hard push plate due to violent impact caused by high-speed hard contact.

[0004] The reason for the hard contact is that the stationary corrugated sheets are at rest, while the running synchronous conveyor belt is moving at high speed. Therefore, when the pusher plate of the high-speed synchronous belt comes into contact with the stationary sheets, a violent impact is inevitable. Since the corrugated sheets are made of soft material, severe damage is unavoidable.

[0005] The best way to solve the problem of impact damage from hard contact is to make the stationary boxes move in advance, so that the pusher plate of the synchronous conveyor belt can contact the box in front during the movement. In this way, the hard contact becomes a soft contact.

[0006] Therefore, the first step is to create a speed difference by using the differential speed principle of the two sets of conveyor belts; then, to achieve buffering by using the speed difference tracking method of the fast speed to track the slow speed; to change hard contact to soft contact through the principle of buffering; to remove the impact caused by hard contact formed by the fast speed through the principle of soft contact; and to avoid damage to the conveyor belt by avoiding impact.

[0007] The specific solution of the present invention is as follows:

[0008] 1. Add a pair of suction conveyor belts between the two synchronous conveyor belts at the inlet of the conveyor bed;

[0009] 2. A suction box that can move back and forth is attached to the underside of the suction belt;

[0010] 3. When the sheet falls from the paper feeding table to the conveyor bed, the suction belt first moves the sheet forward at a speed slightly lower than that of the synchronous conveyor belt;

[0011] 4. When the synchronous conveyor belt starts, its pusher plate follows the box pieces that are running in front from behind;

[0012] 5. When the push plate is about to catch up with the box piece, the suction box closes its suction, and the synchronous conveyor belt catches up from behind and completely takes over the box piece, forming a soft contact between the push plate and the box piece;

[0013] 6. The pusher plate of the synchronous conveyor belt pushes the box pieces forward, completing each subsequent step of the operation step by step.

[0014] What seems like a simple technical problem has remained unsolved in the industry for many years. With the increasing use of non-woven fabric handles, addressing this quality issue has become an urgent technical challenge. This technical solution uses a very simple principle to solve one of the most difficult problems—this is the invention of a technology, the most effective technology the industry has yet to develop. The advantages of this technology are its simple principle, extremely low manufacturing cost, ease of operation, high stability, and wide applicability. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of the present invention. Figure 1-4 The technical solutions of the embodiments of the present invention will be clearly and completely described.

[0021] 1. The paper feeding belt of paper feeding table 9 starts, and sends the box sheet 01 out to the waiting sheet position (position 01A) for standby;

[0022] 2. The extrusion roller 7 and the extrusion pressure roller 6 start to send the box sheet 01 at the position to be extruded (position 01A) to position 01B of the conveyor bed 1;

[0023] 3. The suction box 5 located below position 01B opens the negative pressure air and sucks the upper box piece 01 through the air hole of the suction belt 4. The suction belt 4 carries the box piece 01 forward at a speed slightly lower than that of the synchronous conveyor belt 2.

[0024] 4. The tail of the box piece 01 in the standby position (position 3A) and position 01B of the synchronous belt pusher plate should be kept at a distance of no less than 20cm.

[0025] 5. The synchronous conveyor belt 2 starts and chases the box piece 01 from behind at a speed higher than that of the suction belt 4;

[0026] 6. When the end of the box plate 01 is about to leave the end of the suction belt 4, the suction box 5 closes the negative pressure suction. Before the end of the box plate 01 completely enters the 01C position, the push plate 3 on the synchronous belt 2 catches up with the box plate 01 and completely takes over the box plate 01 from the suction belt 4 during the movement.

[0027] 7. Once the box piece 01 is completely separated from the suction belt 4, it is pushed forward by the push plate 3 of the synchronous conveyor belt 2 and stops at position 01C. At station 8, the gluing operation begins.

[0028] 8. At the same time as the sheet 01 enters position 01C, the sheet delivery roller 7 and the sheet delivery pressure roller 6 send another sheet 01 into position 01B for standby.

[0029] 9. After the adhesive application at station 1 is completed, the synchronous conveyor belt 2 continues to move forward, and the pusher plate 3 at position 3B sends the adhesive-coated box piece 01 downwards to one station. The box piece at position 01B is sent to position 01C in the same manner as steps 3, 4, 5, and 6.

[0030] 10. Following this process, the subsequent box pieces 01 move forward step by step with the synchronous conveyor belt 2, and one box piece at a time enters. The subsequent workstations also carry out their respective operations synchronously.
