Description

Technical Field

[0001] This utility model belongs to the technical field of calendar production equipment and relates to an automatic calendar cutting and stacking device. Background Technology

[0002] A calendar is a printed publication that displays information about a day on each page. It mainly records information such as year, month, day, week, solar terms, and holidays, and is widely used in people's daily lives.

[0003] Currently, calendar production mainly involves processes such as plate making, printing, cutting, and binding. Specifically, a large printing plate for the entire year's days must first be made. Each large plate consists of multiple smaller plates for the same day. A certain number of large-format sheets are then printed from these large plates. The sheets from each plate are then taken sequentially, stacked, cut, and bound to obtain the finished calendar. Because this process requires a large number of printing plates and a large number of sheets with different content, fully automated production is impossible. Instead, general-purpose printing equipment is used to print each plate individually, followed by manual stacking of the sheets. This results in low automation and low production efficiency, and the process is highly susceptible to errors such as misplaced or missing pages due to worker negligence, affecting the quality of the finished product. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an automatic calendar cutting and stacking device. The technical problem to be solved by this invention is: how to achieve automatic cutting and stacking of calendars.

[0005] The objective of this utility model can be achieved through the following technical solution: an automatic calendar cutting and stacking device, characterized in that it includes a frame;

[0006] The first production line, which is set on the frame, is used to receive and transport large sheets of paper;

[0007] A staggered stacking mechanism is provided on the first production line for sequentially stacking large sheets of paper in a staggered manner and then intermittently conveying them backward.

[0008] The first cutting mechanism is set on the first production line and located behind the staggered stacking mechanism. The first cutting mechanism is used to cut the staggered stacked large sheets of paper into long strips of paper.

[0009] The second production line is used to receive the long strips of paper from the first production line, so that the long strips of paper are stacked in a staggered manner and intermittently conveyed to the rear.

[0010] The second cutting mechanism is located on the second production line and is used to cut staggered stacks of long strips of paper into single sheets of paper.

[0011] This utility model adopts an innovative process design. During operation, large sheets of printed paper with multiple calendar pages arranged are first sent to the first production line. Then, under the action of the staggered stacking mechanism, the large sheets of paper are staggered and stacked, and the calendar pages on the large sheets of paper form a continuous stack from top to bottom. Then, through the first cutting mechanism, the stacked large sheets of paper are cut horizontally to form long strips of paper with a single row of calendar pages. The cut strips of paper then enter the horizontally set second production line. For each strip of paper cut by the first cutting mechanism, the second production line is fed horizontally a distance of one page size, so that the strips of paper are staggered on the second production line. The staggered stacks of paper form a calendar page stack containing a continuous set of pages for the whole year from top to bottom. Then, the second cutting mechanism cuts the paper for subsequent binding. This achieves fully automated production, with better production continuity, higher efficiency, and no missing pages or other issues, resulting in more stable and reliable quality.

[0012] In the aforementioned automatic calendar cutting and stacking device, the first production line includes a first conveyor section and a second conveyor section arranged sequentially along its length. The first conveyor section includes an upper conveyor belt and a lower conveyor belt arranged vertically along the length of the first production line, forming a conveying channel for large sheets of paper to pass through. The second conveyor section includes a horizontally arranged conveyor table located below the conveying channel. The first conveyor section provides the power to convey the large sheets of paper to the second conveyor section through the upper and lower conveyor belts working in tandem. The conveyor table of the second conveyor section itself does not have the power to convey large sheets of paper backward. Furthermore, due to the height difference between the second conveyor table and the conveying channel of the first conveyor section, the large sheets of paper are stacked on the conveyor table.

[0013] In the aforementioned automatic calendar cutting and stacking device, a separation mechanism is provided between the first and second conveying sections. This separation mechanism includes a rotating shaft and a drive motor for rotating the shaft. The rotating shaft is mounted above the conveying table along its width. Several eccentrically positioned dials are fixed on the rotating shaft, spaced apart along its length. When the dials rotate, they intermittently contact the large sheets of paper passing below. Since consecutive large sheets of paper may stick together during transport due to their close proximity, when the large sheets enter the second conveying section from the first, the upper dials rotate and contact the tail of the large sheets, propelling them forward. This ensures that the continuously transported large sheets are completely separated and stacked on the conveying table.

[0014] In the aforementioned automatic calendar cutting and stacking device, the staggered stacking mechanism includes a movable frame, a baffle, a translation drive mechanism, and a lifting drive mechanism. The movable frame is movably disposed below the conveyor table. The translation drive mechanism is used to drive the movable frame to reciprocate along the conveyor table. The baffle is movably connected to the movable frame and is horizontally disposed above the conveyor table. The lifting drive mechanism is used to drive the baffle to move up and down relative to the movable frame. After the baffle moves down relative to the movable frame, it can cooperate with the movable frame to form a clamp, and the front end of the baffle can abut against the large sheet of paper conveyed by the first conveyor section. Before a new sheet of paper enters the conveyor table, the moving frame first moves the baffle forward, then the baffle moves down and works in conjunction with the moving frame to clamp and fix the stacked sheets of paper on the conveyor table. When the front end of the new sheet of paper enters the conveyor table and stacks on top of the sheets of paper on the conveyor table, the moving frame moves the stacked sheets of paper backward by a calendar page distance and stops. Then, the new sheet of paper is pushed into the second conveyor section by the first conveyor section and its front end abuts against the front end of the baffle, ensuring that the adjacent sheets of paper are staggered by a calendar page distance after stacking. Then the baffle moves up and moves forward again with the moving frame. This cycle repeats, so that the staggered stacked sheets of paper are intermittently conveyed in the second conveyor section.

[0015] In the aforementioned automatic calendar cutting and stacking device, a pre-knife paper pressing mechanism is also provided between the staggered stacking mechanism and the first cutting mechanism. The pre-knife paper pressing mechanism includes a pressure plate located above the conveyor table and a pressing drive mechanism for driving the pressure plate to move up and down. The pre-knife paper pressing mechanism can press down and fix the large sheet of paper after the staggered stacking mechanism has conveyed it, so that the large sheet of paper can still maintain a stable fit after the staggered stacking mechanism is released.

[0016] In the aforementioned automatic calendar cutting and stacking device, the end of the conveyor table facing the baffle has several clearance slots arranged along the length of the conveyor table. These clearance slots are spaced apart along the width of the conveyor table. The moving frame has several sliding rods that correspond one-to-one with the clearance slots. These sliding rods are embedded in their respective clearance slots and can move back and forth along the slots. In this way, the stop bar and the sliding rod can cooperate to clamp the large stack of paper sheets and move the large stack of paper sheets.

[0017] In the aforementioned automatic calendar cutting and stacking device, the rearward end of the upper conveyor belt extends to the rear side of the staggered stacking mechanism. A blowing assembly is provided on the front side of the conveyor table, which supplies air to the conveyor table and pushes the large sheets of paper upwards. The blowing assembly blows air onto the conveyor table, allowing the air to support the lower surface of the large sheets of paper as they enter the conveyor table, ensuring that the upper surface of the large sheets of paper contacts and engages with the upper conveyor belt. This guarantees that the large sheets of paper are stably conveyed to the front of the baffle to form a staggered stack.

[0018] In the aforementioned automatic calendar cutting and stacking device, the lower end face of the baffle has several clearance grooves for the upper conveyor belt to pass through, and these clearance grooves are spaced apart along the length of the baffle. The clearance grooves prevent the up-and-down movement of the baffle from interfering with the upper conveyor belt.

[0019] In the aforementioned automatic calendar cutting and stacking device, the first cutting mechanism includes a gantry suspension, a first cutter, two eccentric shafts, and a third drive motor. Each eccentric shaft includes a rotating shaft body rotatably connected to the gantry suspension and an eccentric wheel portion eccentrically positioned relative to the rotating shaft body. The first cutter is horizontally positioned, and the two eccentric wheels are rotatably connected to both ends of the first cutter. The third drive motor is driven by the two eccentric shafts and can drive the first cutter to twist and swing up and down. By cooperating with the two eccentric shafts, the first cutter can twist and swing up and down to cut the large stack of paper below, reducing the contact area and extending the cutting path when the first cutter cuts the large stack of paper, ensuring a smooth and flat cut surface, and avoiding the impact of the wide width of the large stack of paper on the cutting effect.

[0020] In the aforementioned automatic calendar cutting and stacking device, a cutter pressing mechanism and a post-cutter pressing mechanism are respectively provided on the front and rear sides of the gantry suspension. Both the cutter pressing mechanism and the post-cutter pressing mechanism can move up and down to press against the large stack of paper below. During the first cut, the cutter pressing mechanism and the post-cutter pressing mechanism can fix the two sides of the large stack of paper respectively, ensuring stability during cutting.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. This utility model adopts an innovative calendar production process design. Through the collaborative operation of various mechanisms, it can automatically stack and cut the printed large sheets of paper in a staggered manner, and then stack and cut the cut strips of paper in a staggered manner to form single-page stacks for subsequent binding. This utility model adopts a fully automated design, resulting in better production continuity, higher efficiency, elimination of human influence, and a significant reduction in the occurrence of misprinted or missing pages, leading to more stable and reliable product quality.

[0023] 2. This utility model has an ingenious design. The first production line adopts a two-section design with high and low distribution. It is then precisely coordinated with the staggered stacking mechanism so that the large sheets of paper are staggered and stacked in the second conveying section, and then intermittently conveyed to the rear so as to cooperate with the first cutting mechanism to cut them into long strips of paper.

[0037] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0038] An automatic calendar splitting and stacking device, such as Figures 1-3 As shown, this utility model adopts a fully automated production line design, including a frame 1. A first production line 2 and a second production line 7 are mounted on the frame 1. The first production line 2 receives and transports large sheets of paper 91. The second production line 7 is horizontally positioned at the tail end of the first production line 2. A staggered stacking mechanism 4 and a first cutting mechanism 6 are sequentially arranged along the transport direction on the first production line 2. A second cutting mechanism 83 is arranged on the second production line 7. The printed large sheets of paper 91 can move backward along the length of the first production line 2, and are stacked by the staggered stacking mechanism 4 to form staggered stacks of large sheets of paper, which are then intermittently transported backward. The large sheets of paper are cut into long strips 92 by the first cutting mechanism 6 and enter the second production line 7. The second cutting mechanism 83 then cuts them into single-page stacks 93 for subsequent binding.

[0039] Specifically, such as Figures 1-4 As shown, the first production line 2 includes a first conveying section and a second conveying section. The first conveying section includes a lower conveyor belt 21 arranged along the length of the first conveying section and an upper conveyor belt 22 located above the lower conveyor belt 21, so that a conveying channel 2a is formed between the upper side of the lower conveyor belt 21 and the lower side of the upper conveyor belt 22. The lower conveyor belt 21 and the upper conveyor belt 22 are driven by the same motor, so that the upper conveyor belt 22 and the lower conveyor belt 21 are kept synchronized. After the printed large sheet of paper 91 enters the conveying channel 2a, it can be stably conveyed to the second conveying section under the clamping of the upper conveyor belt 22 and the lower conveyor belt 21.

[0040] like Figure 4 As shown, the second conveying section includes a conveying table 23, which is a horizontally placed long strip. The height of the conveying table 23 is slightly lower than that of the conveying channel 2a and is adjacent to the conveying channel 2a, so that the large sheets of paper 91 entering the second conveying section are stacked on the conveying table 23.

[0041] Furthermore, to prevent the large sheets of paper 91 from sticking together during continuous transport, a separation mechanism 3 is provided between the first and second transport sections. The separation mechanism 3 includes a rotating shaft 31 and a drive motor 32 for driving the rotating shaft 31 to rotate. The rotating shaft 31 is mounted above the transport table 23 along the width direction of the transport table 23. Several eccentrically arranged dials 33 are spaced along the length direction on the rotating shaft 31. When the tail of the large sheet of paper 91 reaches below the dial 33, the drive motor 32 can drive the dial 33 to rotate, so that the end of the dial 33 farther from the rotation center contacts and abuts against the tail of the large sheet of paper 91, and moves the large sheet of paper 91 to ensure that adjacent large sheets of paper 91 are completely separated for stacking.

[0042] like Figures 5-7 As shown, the staggered stacking mechanism 4 is located in the second conveying section and includes a movable frame 41, a baffle 42, a translation drive mechanism 43, and a lifting drive mechanism 44. Two guide rods 431 are arranged below the conveying table 23 along the length direction of the conveying table 23 and spaced apart along the width direction of the conveying table 23. The movable frame 41 is slidably engaged with the two guide rods 431. The translation drive mechanism 43 includes a transmission belt assembly 432 arranged along the length direction of the guide rods 431 and a second drive motor 433 for driving the transmission belt assembly 432. The transmission belt assembly 432 is located below the movable frame 41, and the movable frame 41 is connected to the upper transmission belt through a connector, so that the second drive motor 433 can drive the movable frame 41 to reciprocate along the length direction of the guide rods 431. The baffle 42 is elongated and located above the conveyor table 23. Both ends of the baffle 42 are slidably connected to the movable frame 41. A lifting drive mechanism 44 is provided between both ends of the baffle 42 and the movable frame 41 to drive the baffle 42 to move up and down relative to the movable frame 41, so that the baffle 42 and the movable frame 41 cooperate to clamp the large sheet of paper. In this embodiment, the lifting drive mechanism 44 is a cylinder. Through the cooperation of the drive motor 32 and the lifting drive mechanism 44, this staggered stacking mechanism 4 can intermittently clamp the stacked large sheet of paper and convey it towards the first cutting mechanism 6. After the baffle 42 moves down, its front end can abut against the newly conveyed large sheet of paper 91 on the conveyor table 23, ensuring that the newly conveyed large sheet of paper 91 forms a precise staggered stack with the large sheet of paper 91 below.

[0043] To ensure that the movable frame 41 and the baffle 42 cooperate while avoiding interference with the conveyor table 23, in this embodiment, the rear end of the conveyor table 23 is provided with several clearance grooves 23a arranged along the length direction. The clearance grooves 23a are distributed at intervals along the width direction of the conveyor table 23. Correspondingly, the movable frame 41 has several sliding rods 411, all of which are arranged along the length direction of the conveyor table 23. The number of sliding rods 411 is the same as that of the clearance grooves 23a and they correspond one-to-one. The sliding rods 411 are respectively embedded in the corresponding clearance grooves 23a and can move back and forth along the length direction of the clearance grooves 23a. The upper end surface of the sliding rod 411 is a smooth plane. After the sliding rod 411 is embedded in the clearance groove 23a, the upper end surface of the sliding rod 411 is basically flush with the conveyor table 23 so as to form a clamping fit with the pressure plate 51.

[0044] like Figure 4 As shown, in this embodiment, the rearward end of the upper conveyor belt 22 extends to the rear side of the staggered stacking mechanism 4. A blower assembly 24 for supplying air to the conveyor platform 23 is also provided on the front side of the conveyor table. The blower assembly 24 can be a blower or a nozzle connected to an air source, creating a certain air pressure on the lower surface of the large sheet of paper 91 entering the conveyor platform 23 and pushing the large sheet of paper 91 upwards. This causes the large sheet of paper 91 to contact the upper conveyor belt 22 extending above the conveyor platform 23, facilitating continued power supply from the upper conveyor belt 22 and moving the large sheet of paper 91 towards the staggered stacking mechanism 4. Furthermore, since the air pressure decreases with distance from the blower assembly 24, once the large sheet of paper 91 abuts against the baffle 42, there is essentially no longer contact between the large sheet of paper 91 and the upper conveyor belt 22. The large sheet of paper 91 can then stably stop in front of the baffle 42 and form a staggered stack with the large sheet of paper 91 below.

[0045] Furthermore, such as Figure 7 As shown, a guide roller 45 is also provided on the movable frame 41. The guide roller 45 is located in front of the baffle 42 and is mounted above the conveyor table 23 along the width direction of the conveyor table 23. The lower side of the upper conveyor belt 22 passes under the guide roller 45 and abuts against the guide roller 45, so that the lower side of the upper conveyor belt 22 is slightly inclined downward along the conveying direction of the first assembly line 2, with an inclination angle of about 1°. Several clearance grooves 42a are opened on the lower end face of the baffle 42. The clearance grooves 42a are distributed at intervals along the length direction of the baffle 42. The width of the clearance grooves 42a is slightly larger than the width of the upper conveyor belt 22, so that the upper conveyor belt 22 passes through the clearance grooves 42a and extends to the rear side of the staggered stacking mechanism 4, avoiding interference.

[0046] Furthermore, a front-knife pressing mechanism 5 is provided between the staggered stacking mechanism 4 and the first cutting mechanism 6 for cooperating with the staggered stacking mechanism 4. The front-knife pressing mechanism 5 includes a pressure plate 51 and a downward pressing drive mechanism. The pressure plate 51 is located above the conveying table 23, and the lower end surface of the pressure plate 51 is a smooth plane. The downward pressing drive mechanism can drive the pressure plate 51 to move up and down. When the staggered stacking mechanism 4 clamps the stacked large sheet of paper and conveys it to the rear position, the front-knife pressing mechanism 5 can take over from the staggered stacking mechanism 4 and continue to press the large sheet of paper.

[0047] like Figure 2 , Figure 8 As shown, the first cutting mechanism 6 is located at the tail of the first production line 2, and includes a gantry suspension 61, a first cutter 62, two eccentric shafts 63, and a drive motor 64. The gantry suspension 61 is mounted above the conveyor table 23 and has two spaced-apart crossbeams 611. The first cutter 62 is laterally movable in the gap between the two crossbeams 611 via the two eccentric shafts 63. Specifically, as... Figure 9 As shown, the eccentric shaft 63 includes a shaft body 631 and an eccentric wheel 632. The shaft body 631 is elongated, and the eccentric wheel 632 is disc-shaped. The eccentric wheel 632 is located in the middle of the shaft body 631 and is eccentrically positioned relative to the shaft body 631. Both eccentric shafts 63 are mounted between two crossbeams 611, and both ends of the shaft body 631 are rotatably connected to the two crossbeams 611. Both ends of the first cutter 62 are rotatably connected to the eccentric wheel 632 of the two eccentric shafts 63, and there is a certain angle difference between the eccentric wheel 632 of the two eccentric shafts 63. The drive motor 64 is connected to the shaft body 631 of the two eccentric shafts 63 through chain drive or gear drive, so that the drive motor 64 can drive the first cutter 62 to perform up-and-down twisting cutting motion on the large stack of paper below.

[0048] Furthermore, such as Figure 8 As shown, to ensure the stability of the large sheet of paper during cutting, a cutter pressing mechanism 65 and a post-cutter pressing mechanism 66 are respectively provided on the front and rear sides of the gantry suspension 61, so that the first cutter 62 is located between the cutter pressing mechanism 65 and the post-cutter pressing mechanism 66. In this embodiment, the structure of the cutter pressing mechanism 65 is basically the same as that of the front-cutter pressing mechanism 5. The post-cutter pressing mechanism 66 adopts two hydraulic cylinders arranged at intervals, with the hydraulic cylinders facing downwards and located directly above the second production line 7. This allows the cutter pressing mechanism 65 and the post-cutter pressing mechanism 66 to press the front and rear sides of the large sheet of paper to be cut before cutting. Moreover, before cutting, the tail of the large sheet of paper is directly fixed to the conveyor belt of the second production line 7 by the post-cutter pressing mechanism 66, so that the cut long strip of paper 92 is directly formed on the second production line 7 for easy subsequent conveying.

[0049] like Figure 2 , Figure 10 As shown, the second production line 7 uses a conveyor belt 71 for conveying. The height of the conveyor belt 71 is slightly lower than the height of the conveyor table 23, and the conveyor belt is arranged horizontally below the first cutting mechanism 6 relative to the conveyor table 23. By controlling the drive motor of the conveyor belt 71, the conveyor belt 71 can achieve intermittent conveying. That is, every time the first cutting mechanism 6 cuts, the conveyor belt 71 feeds a certain distance, so that the long strip paper stack 92 forms a continuous staggered stack, and the staggered stack of long strip paper stack 92 is conveyed to the second cutting mechanism 83 for cutting, and the long strip paper stack 92 is cut into a single-page stack 93 containing a year's calendar pages.

[0050] Furthermore, in this embodiment, the second production line 7 is provided with a positioning plate 81 and an alignment mechanism 82 on both sides of the conveyor belt 71. The positioning plate 81 is in the shape of a long strip and is located on the side of the conveyor belt 71 near the conveyor table 23 along the length direction of the conveyor belt 71. The alignment mechanism 82 is located on the other side of the conveyor belt 71 and includes a push plate 821 and a transverse drive mechanism 822 for driving the push plate 821 to move back and forth relative to the positioning plate 81. The long strip of paper stack 92 formed after being cut by the first cutting mechanism 6 can fall between the positioning plate 81 and the push plate 821. By driving the push plate 821 to laterally squeeze the long strip of paper stack 92 and make the long strip of paper stack 92 fit against the side wall of the positioning plate 81, the long strip of paper stack 92 is kept neat.

[0051] Furthermore, in order to ensure the neatness of the long strip of paper stack 92 when the second cutting mechanism 83 cuts it, a similar cutter pressing mechanism 65 is also provided on the front side of the second cutting mechanism 83 in this embodiment.

[0052] like Figure 11 , 12As shown, the working principle of this utility model is as follows: First, the printed large sheets of paper 91 are continuously input from the front end of the first production line 2. The large sheets of paper 91 enter the conveyor table 23 with the cooperation of the upper conveyor belt 22 and the lower conveyor belt 21, and abut against the falling baffle 42, so that the large sheets of paper 91 are stacked in a staggered manner. Then, the paper pressing mechanism 5 drives the pressure plate 51 to move down, replacing the baffle 42 to fix the stacked large sheets of paper 91 on the conveyor table. The staggered stacking mechanism 4 drives the baffle 42 to move up and drives the moving frame 41 to move forward a distance of one calendar page size. Then, the baffle 42 descends and cooperates with the moving frame 41 to clamp the newly stacked large sheets of paper. The paper pressing mechanism 5 drives the pressure plate 51 to move up, and the staggered stacking mechanism 4 drives the moving frame 41 and drives the clamped large sheets of paper to move backward a distance of one calendar page size, so that the front end of the large sheets of paper passes through the first cutting mechanism 6 and extends into On the conveyor belt of the second production line 7, the cutting and pressing mechanism 65 and the post-cutting pressing mechanism 66 fix the two sides of the large sheet paper stack to be cut. The first cutting mechanism 6 drives the first cutter 62 to cut, so that the part of the large sheet paper stack that extends into the second production line 7 forms a long strip paper stack 92, and the newly formed long strip paper stack 92 forms a staggered stack with the previously formed long strip paper stack 92. Then, the alignment mechanism 82 drives the push plate 821 to press the side of the long strip paper stack 92 once, so that the long strip paper stack 92 is aligned with the positioning plate 81 on the other side. Then, the conveyor belt drives the staggered stack of long strip paper stack 92 forward a distance of one page size, so that the front end of the long strip paper stack 92 passes through the second cutting mechanism 83. After the second cutting mechanism 83 is fixed by the cutter pressing, it cuts the long strip paper stack 92, so that the front end of the long strip paper stack 92 forms a single-page stack 93, ready for subsequent binding.

[0053] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this invention. Those skilled in the art to which this invention pertains may make various modifications to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this invention or exceeding the scope defined by the appended claims.

[0054] Although this document frequently uses terms such as frame 1, lower conveyor belt 21, upper conveyor belt 22, conveyor table 23, paper pressing mechanism 5, first cutting mechanism 6, and conveyor belt 71, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
