Description

Technical Field

[0001] The invention relates to the technical field of paper collection of printing equipment, in particular to a layered paper collection device and a layered paper collection method. Background Art

[0002] In a printing factory, the printed products after processing need to be collected, stacked and bundled to facilitate subsequent transfer, storage and logistics transportation. Generally speaking, printing equipment is equipped with a paper collection device. Most of the paper collection devices (also commonly known as paper stackers or paper stacking tables) can only collect printed products in a straight up and down manner. Each time the paper stacking is completed, the machine needs to be stopped to remove the paper stack, which is relatively inefficient.

[0003] In the prior art, there is a Chinese invention patent with publication number CN220617837U, entitled "A layered paper collection device". When conveying printed products, the device uses the up and down tilting action of a guide plate to change the conveying angle of the printed products, so that the printed products are conveyed to an upper paper collection unit or a lower paper collection unit, thereby completing the layered paper collection work.

[0004] This printed matter layered conveying structure needs to accurately convey the printed matter to the upper and lower paper collection units, so it is necessary to ensure that when the guide plate tilts downward, the paper can completely avoid the upper conveying structure. However, as is well known, first, paper has a certain hardness, especially hardcover printed matter (color pages, exquisite brochures, etc.), which is difficult to bend with the downward tilt of the guide plate, and then smoothly enter the lower paper collection unit. Then this leads to the need for the specification of the guide plate to be very large, at least exceeding the size of general printed matter, and the layered paper collection device needs to be lengthened and enlarged, which is not conducive to the effective use of the equipment space, and even causes the size of the equipment to exceed the width and height limit requirements, affecting handling and logistics; second, the printed matter is conveyed at a high speed, and may float directly from the downward tilting guide plate under the action of inertia, and cannot enter the lower paper collection unit, which is prone to miscollection or blockage of printed matter. Therefore, the existing layered paper collection device has certain inconveniences in use. Summary of the invention

[0005] The object of the present invention is to provide a layered paper collection device and a layered paper collection method to solve the inconvenience of using the existing layered paper collection device, such as low effective utilization of equipment space and easy occurrence of printed matter miscollection or blockage.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: A layered paper collection device comprises a frame and a paper distribution mechanism, a paper transfer mechanism and a paper collection mechanism all mounted on the frame; The dynamic paper discharging end of the paper distributing mechanism is matched with the paper feeding end of the paper guiding mechanism and the paper feeding end of one of the paper receiving mechanisms; The paper output end of the paper delivery mechanism is matched with the paper input end of the other paper receiving mechanism; The paper distribution mechanism includes a telescopic cylinder, a fixed plate, a fixed roller, a paper feeding roller and a paper pressing roller. The fixed roller is rotatably mounted on the frame. The two fixed plates are symmetrically arranged and rotatably connected to the two ends of the fixed roller. The two ends of the telescopic cylinder are respectively hinged to the frame and the fixed plate. The paper feeding roller and the paper pressing roller are both rotatably mounted on the fixed plate. A dynamic paper output channel is formed between the fixed roller, the paper feeding roller and the paper pressing roller.

[0007] A further technical solution is that the minimum roller distances among the fixed roller, the paper feeding roller and the paper pressing roller are consistent.

[0008] A further technical solution is: a paper pressing belt machine corresponding to the two paper collecting mechanisms is also arranged on the frame.

[0009] A further technical solution is that the paper transfer mechanism is a belt conveyor.

[0010] A further technical solution is: the paper receiving mechanism includes a paper receiving platform, a fork platform, a rodless cylinder, a load-bearing plate, a slider, a screw, a motor and a paper stop assembly, the paper receiving platform is tiltedly installed on the frame, the fork platform is installed on the movable end of the rodless cylinder, and the fork platform is adapted to the paper receiving platform, the rodless cylinder is installed on the load-bearing plate, the load-bearing plate is installed on the slider, the slider is threadedly connected to the screw, the screw is rotatably installed on the frame, the motor is installed on the frame, and the power output end of the motor is transmission-connected to the screw through a transmission structure, the paper stop assembly is installed on the frame, and the paper stop assembly is adapted to the fork platform.

[0011] A further technical solution is: the paper blocking assembly includes a first cylinder and a fork plate, the first cylinder is installed on the frame, the fork plate is installed on the power output end of the first cylinder, and the fork plate is adapted to the fork platform.

[0012] A further technical solution is that a paper pusher driven by a second cylinder is slidably installed in the slide groove of the paper receiving table.

[0013] A further technical solution is: a turning table adapted to the paper collecting mechanism is rotatably mounted on the frame, and the turning table and the frame are respectively hinged to two ends of the third cylinder.

[0014] A further technical solution is: a paper baffle is slidably installed on the turning table, and the paper baffle is connected to the power output end of the fourth cylinder.

[0015] The layered paper collection method uses a layered paper collection device, comprising the following steps: S1. The controller on the layered paper receiving device identifies the paper receiving mechanism without paper under the signal feedback from the material sensor on the paper receiving mechanism; S2. The telescopic cylinder on the paper distribution mechanism rotates with the fixed plate to control the direction of the dynamic paper output channel between the paper feeding roller and the paper pressing roller, so that the printed matter is transported toward the paper collection mechanism without paper; S3. The printed matter enters the paper distribution mechanism through the conveyor belt, and then enters the paper collection mechanism without paper, and the paper collection and stacking process is completed on the paper collection mechanism, while the removal and bundling of the paper stacks on the other paper collection mechanisms are not affected.

[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: The present invention proposes a layered paper collection device, which can use a paper feeding mechanism to accurately control the conveying direction of printed products, is not affected by the hardness, size and conveying speed of the printed products, ensures that the paper collection mechanisms can accurately collect the corresponding printed products, and can achieve the purpose of high-speed production; and the two paper collection mechanisms do not interfere with each other, that is, the paper collection and stacking process is carried out on one paper collection mechanism, while not affecting the removal and bundling of paper stacks on other paper collection mechanisms.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Embodiment 1: In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a layered paper collection device comprises a frame 1 and a paper distribution mechanism 2, a paper transfer mechanism 3 and a paper collection mechanism 4, all of which are installed on the frame 1; The dynamic paper discharging end of the paper distributing mechanism 2 is matched with the paper feeding end of the paper guiding mechanism 3 and the paper feeding end of one of the paper receiving mechanisms 4; The paper output end of the paper delivery mechanism 3 is matched with the paper input end of another paper receiving mechanism 4; The paper distributing mechanism 2 comprises a telescopic cylinder 5, a fixed plate 6, a fixed roller 7, a paper feed roller 8 and a paper pressing roller 9. The fixed roller 7 is rotatably mounted on the frame 1. The two fixed plates 6 are symmetrically arranged and rotatably connected to the two ends of the fixed roller 7. The two ends of the telescopic cylinder 5 are hinged to the frame 1 and the fixed plate 6 respectively. The paper feed roller 8 and the paper pressing roller 9 are both rotatably mounted on the fixed plate 6. A dynamic paper discharge channel is formed between the fixed roller 7, the paper feed roller 8 and the paper pressing roller 9.

[0033] It should be pointed out that the device is equipped with an industrial controller and sensors, such as a material sensor compatible with the paper collection mechanism 4 installed on the frame, and a photoelectric counter set at the paper distribution mechanism 2. The material sensor is used to feedback the material situation on the paper collection mechanism 4, and the counter is used to identify the amount of material distributed each time, so as to achieve the purpose of accurately controlling the paper collection work.

[0034] The working process of the device is as follows: printed matter or paper etc. arrive at the sheet distributing mechanism 2 through the external conveyor. At this time, first, the controller on the layered paper receiving device identifies the paper receiving mechanism without paper under the signal feedback of the material sensor on the paper receiving mechanism, and the paper receiving mechanism is ready for paper receiving; then, the telescopic cylinder 5 on the paper distributing mechanism 2 rotates with the fixed plate 6, and then controls the direction of the dynamic paper discharge channel between the paper feeding roller 8 and the paper pressing roller 9. The printed matter is constrained and guided by the dynamic paper discharge channel to accurately control the conveying direction and conveying posture of the printed matter, so that the printed matter can be smoothly conveyed in layers without being affected by the hardness, size and conveying speed of the printed matter, ensuring that the paper receiving mechanism can accurately collect the corresponding printed matter and achieve the purpose of high-speed production; finally, the printed matter is conveyed toward the paper receiving mechanism without paper, and the printed matter enters the paper distributing mechanism through the conveyor belt, and enters the paper receiving mechanism without paper, and the paper collecting and stacking process is completed on the paper receiving mechanism, while not affecting the removal and bundling of the paper stacks on the other paper receiving mechanisms.

[0035] It is worth noting that the fixed roller 7 of the paper feeding mechanism 2 remains stationary and is always flush with the external conveyor.

[0036] It is worth noting that: Figure 3 As shown, the fixed roller 7, the paper feeding roller 8 and the paper pressing roller 9 are in a triangular shape, that is, the fixed roller 7 and the paper feeding roller 8, the paper feeding roller 8 and the paper pressing roller 9 can all form a paper discharge channel. When the telescopic cylinder 5 micro-drives the fixed plate 6 to rotate at a small angle, the printed matter can pass through any one of the two paper discharge channels, and the angles of the two paper discharge channels differ greatly, thereby achieving a small rotation and an amplification effect of the paper conveying direction.

[0037] Preferably, the minimum roller distances among the fixed roller 7, the paper feeding roller 8 and the paper pressing roller 9 are consistent.

[0038] On the basis that the fixed roller 7 and the paper feeding roller 8, the paper feeding roller 8 and the paper pressing roller 9 can all form a paper discharge channel, it is ensured that printed products of the same specification can pass smoothly when any paper discharge channel is selected.

[0039] Preferably, the frame 1 is also provided with a paper pressing belt machine 10 corresponding to the two paper receiving mechanisms 4 on a one-to-one basis.

[0040] The paper pressing belt machine 10 is composed of a plurality of belt rollers and thin belts stretched on the belt rollers. The active belt rollers are driven by a motor to rotate, thereby pressing the paper passing under the paper pressing belt machine 10 to prevent high-speed paper from floating and playing a certain guiding role.

[0041] Preferably, the paper conveying mechanism 3 is a belt conveyor.

[0042] The belt conveyor is equipped with a rotatable boat-shaped paper presser to press the paper passing over the belt conveyor to prevent high-speed paper from floating.

[0043] Embodiment 2: Based on the above embodiments, this embodiment Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the paper receiving mechanism 4 includes a paper receiving platform 11, a fork platform 12, a rodless cylinder 13, a bearing plate 14, a slider 15, a screw 16, a motor 17 and a paper stop assembly 18. The paper receiving platform 11 is tiltedly installed on the frame 1, the fork platform 12 is installed on the movable end of the rodless cylinder 13, and the fork platform 12 is adapted to the paper receiving platform 11, the rodless cylinder 13 is installed on the bearing plate 14, the bearing plate 14 is installed on the slider 15, the slider 15 is threadedly connected to the screw 16, the screw 16 is rotatably installed on the frame 1, the motor 17 is installed on the frame 1, and the power output end of the motor 17 is transmission-connected to the screw 16 through a transmission structure, the paper stop assembly 18 is installed on the frame 1, and the paper stop assembly 18 is adapted to the fork platform 12.

[0044] Before receiving the paper, the motor 17 drives the lead screw 16 to rotate, thereby adjusting the slider 15 and the components thereon (the fork platform 12, the rodless cylinder 13 and the load-bearing plate 14) to rise together, that is, away from the paper receiving platform 11, and adjusting the position of the fork platform 12 with the help of the rodless cylinder 13. Specifically, for example, the length of the head of the fork platform 12 from the paper stop assembly 18 is adjusted to adapt to the size of the printed matter or to ensure that the printed matter can completely fall on the head position of the fork platform 12, and then the papers fall one by one and continuously on the head position of the fork platform 12. At this time, because the fork platform 12 is tilted and has a paper stop assembly 18 at the lower end, the printed matter is Under the action of gravity, the paper stack is aligned when it falls. As the paper stack on the fork platform 12 rises, the motor 17 drives the screw 16 to rotate, controlling the fork platform 12 to descend until the printed matter collected on the fork platform 12 meets certain requirements (such as quantity, height or weight, etc., and corresponding sensors collect corresponding information). At this time, the fork platform 12 returns to the paper receiving platform 11, and under the action of the rodless cylinder 13, the fork platform 12 moves away from the paper blocking assembly 18, and then places the paper stack on the paper receiving platform 11, completing the paper collection work. When using other paper collection mechanisms 4 without objects to collect paper, the collected paper stack can be removed.

[0045] Preferably, the paper blocking assembly 18 includes a first cylinder 19 and a fork plate 20 , the first cylinder 19 is mounted on the frame 1 , the fork plate 20 is mounted on the power output end of the first cylinder 19 , and the fork plate 20 is adapted to the fork platform 12 .

[0046] The fork plate 20 is lifted up under the driving of the first cylinder 19, and the fork plate 20 passes through the gap on the fork platform 12 and rises, playing the role of blocking and aligning the paper.

[0047] Preferably, a paper pusher 22 driven by a second cylinder 21 is slidably installed in the slide groove of the paper receiving platform 11 .

[0048] After the corresponding paper receiving mechanism 4 has completed the stacking of paper, the second cylinder 21 can be used to drive the paper pusher 22 to slide in the slide groove of the paper receiving platform 11 to push the paper stack out of the paper receiving mechanism for easy paper removal.

[0049] Preferably, a turning table 23 adapted to the paper receiving mechanism 4 is rotatably mounted on the frame 1 , and the turning table 23 and the frame 1 are hinged to two ends of the third cylinder 24 , respectively.

[0050] The paper stack in the paper collecting mechanism 4 can be guided to the turning platform 23. At this time, the paper stack is in an inclined state. The turning platform 23 is leveled with the help of the third cylinder 24 to straighten the paper stack.

[0051] Preferably, a paper baffle 25 is slidably mounted on the turning platform 23 , and the paper baffle 25 is connected to the power output end of the fourth cylinder 26 .

[0052] The fourth air cylinder 26 drives the paper stopper 25 to stop the inclined paper stack on the turning platform 23 .

[0053] The layered paper collection method uses a layered paper collection device, comprising the following steps: S1. The controller on the layered paper receiving device identifies the paper receiving mechanism without paper under the signal feedback from the material sensor on the paper receiving mechanism; S2. The telescopic cylinder on the paper distribution mechanism rotates with the fixed plate to control the direction of the dynamic paper output channel between the paper feeding roller and the paper pressing roller, so that the printed matter is transported toward the paper collection mechanism without paper; S3. The printed matter enters the paper distribution mechanism through the conveyor belt, and then enters the paper collection mechanism without paper, and the paper collection and stacking process is completed on the paper collection mechanism, while the removal and bundling of the paper stacks on the other paper collection mechanisms are not affected.

[0054] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
