Description

Technical Field

[0001] The present application relates to the field of printing and binding, and in particular to a digital printing booklet stacking device. Background Art

[0002] As the demand for books continues to grow, book binding automation equipment is becoming more and more mature. The text content is digitally printed on the roll, and the roll passes through the book binding automation equipment after folding, cutting, gluing, stacking and wrapping to produce a successfully bound book.

[0003] In the existing technology for roll-to-roll digital printing, book pages are folded and cut into book sheets. During the high-speed transmission of the book sheets and the stacking of them into book cores, the vibration or impact of the book sheets during the high-speed transmission process may cause them to shift or become unstable, resulting in inaccurate alignment during stacking. It is also easy for the speed of the conveyor belt and the action of the stacking device to be uncoordinated, and the book sheets may not have enough time to be accurately positioned when they are transmitted to the stacking position, resulting in uneven stacking. In response to this problem, it has been proposed to reduce the transmission speed so that the equipment can spend more time to more accurately position the book sheets.

[0004] However, the above technical solution reduces the transmission speed of book pages, thereby taking more time to stack the book pages, which greatly reduces the production efficiency of books. Therefore, a digital printing book page stacking device is needed that can accurately stack the book pages without reducing the transmission speed of the book pages. Summary of the invention

[0074] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0075] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and similar expressions used herein are for illustrative purposes only.

[0076] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0077] Before going into detail, it should be noted that this device is used in a high-speed book binding device, and the binding process of the high-speed book binding device is as follows:

[0078] Place the printed paper roll in the unwinding device and unwind it to form a continuous paper strip. (The printed paper roll is: Using high-speed digital printing equipment, multiple pages can be printed on a continuous roll at the same time to ensure efficient production.)

[0079] In order to facilitate the subsequent book forming, the paper roll will be folded along the width direction. This folding process can be understood as arranging the pages in the order required by the final book, which is convenient for subsequent binding.

[0080] After folding, the book is cut to the required length. Through precise cutting steps, "signatures" are formed. Each signature is usually a signature of a book, including multiple pages folded together.

[0081] The above content is prior art, and therefore, it will not be described in detail.

[0082] See also Figure 1-Figure 22 Specifically, the sliding direction of the upper conveyor belt 11 and the lower conveyor belt 12 is the conveying direction F1. The signatures are arranged in a fish scale shape and conveyed between the upper conveyor belt 11 and the lower conveyor belt 12. The upper and lower conveyor belts clamp the signatures and continuously convey the signatures along the conveying direction F1. The paths along which the upper and lower conveyor belts convey the signatures form a conveying area 13. The signatures are arranged in a fish scale shape and conveyed, which makes the conveying efficiency of the signatures higher.

[0083] In the sliding direction where the upper conveyor belt 12 and the lower conveyor belt 12 work together, there are tension wheels and equidistant guide wheels. The tension wheel is usually installed at a fixed position or an adjustable position of the conveyor belt, and the tension of the conveyor belt is adjusted by a mechanical device (such as a spring or a pneumatic device). During the conveying process, the tension wheel will be dynamically adjusted according to the actual state of the conveyor belt to ensure that the conveyor belt always maintains appropriate tension.

[0084] Guide wheels are usually installed at specific locations along the conveyor path, especially in areas where the conveyor belt is prone to deviation or requires additional support. The installation position of the guide wheels is precisely calculated to ensure that the conveyor belt always runs along the designed path at high speeds, avoiding deviation or slack.

[0085] The signature is conveyed to the conveying area 13 , in which a detection assembly 30 , a glue dispensing mechanism 40 and a book separation mechanism 50 are sequentially arranged along the conveying direction F1 .

[0086] The book section first passes through the detection component 30, and the book section camera 31 captures the book section content on the book section (such as the printed QR code and the number of book section pages and other information) to generate a book section signal. When the printed content is incomplete, the counting sensor 32 detects the number of book sections clamped and conveyed by the upper and lower conveyor belts 12. The upper and lower conveyor belts 12 clamp and convey the book section so that the book section will not fall off the conveyor belt due to the weight of the book section during high-speed transmission, making the counting sensor 32 more accurate, and the book section is fixed between the upper conveyor belt 11 and the lower conveyor belt 12, so that the book section camera can accurately capture the book section content printed on the book section.

[0087] The book signatures then pass through the glue dispensing assembly, and the glue gun 42 connected to the glue production assembly 41 continuously dispenses glue and dispenses glue to the book signatures in the conveyor belt.

[0088] The glued book passes through the book separation mechanism 50, which is electrically connected to the detection component 30 to receive the book separation signal. When the glued book separation mechanism 50 receives the book separation signal, the connecting rotating shaft in the electromagnet 51 rotates to drive the hook plate 52 connected to the rotating shaft to move downward until it abuts against the book, so that the abutted book is separated from the book transmitted at the last moment. When the glued book separation mechanism 50 does not receive the book separation signal, the book separation mechanism 50 does not work. The glued book is transmitted to the stacking area 23 connected to the transmission area 13.

[0089] The book receiving and stacking mechanism 20 (including the plurality of position limiting components and the book receiving component 22) and the book pushing mechanism 60 are sequentially arranged along the guide direction F2, and the guide direction F2 is arranged vertically downward with the conveying direction F1. The stacking area 23 is arranged side by side with the stacking area 23 along the conveying direction F1, but the stacking area 23 is located below the conveying area 13.

[0090] A plurality of limiting components 21 are provided according to the number of edges of the signature.

[0091] In one embodiment, the book is rectangular and includes four edges. The glued book signature is transported from the book outlet end of the upper conveyor belt 11 to the stacking area 23. By setting the positions of the front, rear, left, and right limiter components 214 in advance, one limiter component is attached to one edge of the book signature, and four limiter components surround the four edges of the book signature. In addition, a book receiving conveyor belt 2112 is provided in each limiter component. The book receiving conveyor belt 2112 is attached to the book signature. When the book receiving conveyor belt 2112 slides along the guide direction F2, it drives the book signature to slide along the guide direction F2 to the book receiving component 22 to form a book receiving platform 2212. The book signatures are stacked on the book receiving platform 2212, and a plurality of book signatures are stacked to form a book block.

[0092] The four limiting components are enclosed and pasted to form a stacking area 23. When viewed along the guide direction F2, the area of ​​the stacking area 23 is equal to the flat area of ​​the signature when it is transported.

[0093] The limiter components prevent the signatures from being misplaced or slipping during the conveying process, and they are kept neatly arranged, which is crucial for the smooth progress of the subsequent stacking process.

[0094] The four limiting components are arranged in a rectangular shape and correspond to the four edges of the signature. During the transmission process, the four edges of the signature are respectively in contact with the front, rear, left and right limiting components 214 to stabilize the position of the signature.

[0095] The front stopper assembly 211 is connected to the lower conveyor belt 12 and mainly controls the front edge of the book signature to ensure that the book signature can accurately enter the designated position when being conveyed to the stacking area 23 .

[0096] The rear stopper assembly 212 blocks and stabilizes the rear edge of the signature to prevent the signature from shifting when the conveyor belt stops.

[0097] The left limit assembly 213 and the right limit assembly 214 are perpendicular to the conveying direction F1 and are mainly used to control the left and right edges of the signature to ensure that the left and right positions of the signatures on the conveyor belt are accurate.

[0098] The position of the stopper can be fine-tuned according to the size of the signature to accommodate signatures of different sizes. This flexibility ensures that the conveying and stacking process is suitable for signatures of different sizes.

[0099] When the book signature is delivered to the stacking area 23 , the limiting assembly will automatically adjust its position to fit the four edges of the book signature to provide an enclosed frame to prevent the book signature from tilting or sliding during the stacking process.

[0100] During the stacking process, the stopper not only fixes the book, but also ensures its vertical alignment by enclosing the edges of the book. This means that each book is kept on the same horizontal line when stacked, without offset or overlap, thus forming a neat book block.

[0101] Since the stacking area 23 formed by the limiting assembly is equal to the paving area, the limiting assembly provides a precise spatial constraint to ensure that each signature will not move outward or lose control when stacking, thereby greatly improving the stacking accuracy.

[0102] The book receiving conveyor belt 2112 is a part of the limiting assembly, and a limiting assembly is attached to one edge of the signature to further ensure that the signature remains stable during the conveying process. The book receiving conveyor belt 2112 guides the signature from the conveyor belt to the stacking area 23, and when the signature enters the stacking area 23, it helps it slide to the correct position to avoid jamming or deviation in the final stage of conveying.

[0103] The front stopper assembly 211 is connected to the lower conveyor belt 12 and is located at the book outlet end of the conveying area 13. The book receiving conveyor belt 2112 provided on the front stopper assembly 211 is formed by bending the lower conveyor belt along the guide direction F2. One edge of the signature has been in contact with the conveyor belt (the upper and lower conveyor belts and the book receiving conveyor belt 2112) before being stacked, so that the signature completes the transition from the conveying area 13 to the stacking area 23.

[0104] When the book reaches the end of the lower conveyor belt 12, the bent book receiving conveyor belt 2112 can catch the edge of the book to prevent the book from falling or sliding due to loss of support. This ensures that the book smoothly transitions from the conveyor belt to the stacking area 23, forming a continuous conveying process.

[0105] The book receiving conveyor belt 2112 is bent along the guiding direction F2, so that the book signature can be transferred from horizontal to vertical transmission, and the book signature can be gradually guided into the stacking area 23. The guiding direction F2 is perpendicular to the main transmission direction F1, and this bending structure ensures that the book signature changes the transmission path at the end of the conveyor belt and accurately enters the stacking area 23 without deviation or misalignment.

[0106] The bent book receiving conveyor belt 2112 fits one edge of the signature, and plays a role in precise positioning. The bending structure ensures that the signature always keeps in contact with the book receiving conveyor belt 2112 and moves smoothly along the conveying direction F1, avoiding left and right deviation of the signature during the conveying process.

[0107] The book receiving conveyor belt 2112 in the front limiting assembly 211 can also ensure that the edges of the book signatures are aligned before stacking, so that each book signature maintains a consistent direction, providing an accurate basis for subsequent stacking.

[0108] A limiting assembly is used in conjunction with a book receiving conveyor belt 2112 and in contact with an edge of a book signature, so that the transmission of the book signature in the guide direction F2 is precisely controlled, ensuring that each book signature can be stacked together according to a predetermined path and sequence. This can avoid problems such as uneven stacking and tilting of the book signatures, and improve the accuracy and quality of stacking.

[0109] In the process of transferring the book signature to the book receiving platform 2212, the book receiving conveyor belt 2112 pushes the book signature to the correct position by continuously sliding, so as to ensure that the book signature will not tilt or be stacked unevenly when stacked. Each book signature is stacked smoothly under the guidance of the book receiving conveyor belt 2112.

[0110] The book receiving conveyor belt 2112 ensures that the book signatures can be smoothly transferred when being conveyed to the stacking area 23, and will not be misplaced or slipped due to inertia or friction. This improves the stability and accuracy of book signature stacking, ensures that the book signatures are clearly layered and neatly aligned when stacked, and reduces production problems caused by uneven stacking.

[0111] In the specific implementation, the various parts of the entire limiting assembly are closely connected to form an automatic adjustment, limiting and precise stacking system. The fixed plate 2111 provides a basic limiting structure to enclose the book to ensure that it does not deviate during the stacking process; the book receiving conveyor belt 2112 is responsible for accurately conveying the book to the stacking area 23; the vibrator 2113 fine-tunes the book through vibration force to ensure that each layer of the book is stacked neatly; the adjustment motor 2114 and the sliding member 2115 work together to enable the position of the fixed plate 2111 to be dynamically adjusted according to the book of different specifications, ensuring that the equipment can handle book of various sizes.

[0112] In a specific implementation, the book receiving component 22 is composed of a first book receiving component 221 and a second book receiving component 222; the book receiving component 22 includes two book receiving rods 2211 that are relatively and staggered, and the two book receiving rods 2211 slide toward each other in the stacking area 23 to form a book receiving platform 2212, and the book signatures are stacked on the book receiving platform 2212; the two relatively arranged fixing plates 2111 are provided with two corresponding and staggered through holes 21111, one of the book receiving rods 2211 passes through the one through hole 21111 and is located in the stacking area 23, and the other book receiving rod 2211 passes through the other through hole 21111 and is located in the stacking area 23.

[0113] The first book receiving assembly 221 and the second book receiving assembly 222 work alternately to reduce the waiting time.

[0114] In a specific implementation, the digital printing book stacking device 100 further includes a book pushing mechanism 60, which includes: a placement table 61, a slide rail 62, a book pushing lever 63 and a cam member 65. The placement table 61 is located below the book receiving platform 2212 to receive the book block. The slide rail 62 is fixed below the placement table 61. The book pushing lever 63 is slidably connected to the slide rail 62, and one of the book pushing levers 63 is slidably connected to one of the slide rails 62, and the other of the book pushing levers 63 is slidably connected to the other of the slide rails 62. The pushing motor 64 is connected to the book pushing lever 63, and the pushing motor 64 generates a horizontal pushing force. One end of the cam member 65 is electrically connected to the pushing motor 64, and the other end of the cam member 65 is connected to the slide rail 62 to generate a vertical rod retracting force, and one of the cam mechanisms is connected to one of the slide rails 62, and the other of the cam mechanisms is connected to the other of the slide rails 62.

[0115] When the book receiving rod 2211 slides in a direction away from the stacking area 23, the book block is transferred to the placement table 61 below according to gravity, ensuring that the book block is in the correct position to prepare for the book pushing action.

[0116] After the placing table 61 receives the book block, the pushing motor 64 drives the book pushing lever 63 to slide on the slide rail 62, pushing the book block to the next station. After the book pushing lever 63 completes the book pushing action, the cam member 65 acts on the book pushing lever 63 to reset it. Each feature plays a key role in ensuring the accurate and fast pushing of the book block. A set of push rod power devices are provided on both sides of the placing table 61. When one of the book pushing levers 63 is driven to push the book, the other book pushing lever 63 is driven to reset, and the two book pushing levers 63 realize the action of alternately pushing the book.

[0117] In a specific implementation, the digital printing signature stacking device 100 further includes a clamping mechanism 70, which is arranged side by side with the book pushing mechanism 60 along an end away from the clamping and conveying assembly 10, and the clamping mechanism 70 includes:

[0118] The book discharging assembly 71 is arranged side by side with the placing table 61, and the horizontal pushing direction of the book pushing lever 63 is the direction in which the book pushing mechanism 60 approaches the pressing mechanism 70. The book discharging assembly 71 includes: a book discharging conveyor belt 711 sliding along the horizontal pushing direction and a first detection member 712 located on the side of the book discharging conveyor belt 711 and receiving the book block;

[0119] The pressing assembly 72 is arranged side by side with the book output assembly 71. The book output assembly 71 is located between the book pushing mechanism 60 and the pressing assembly 72. The pressing assembly 72 includes:

[0120] The conveyor belt 721 is arranged side by side with the book delivery conveyor belt 711, and the sliding direction of the conveyor belt 721 is arranged in the same direction as the book delivery conveyor belt 711. The book pressing member 722 is located above the conveyor belt 721, and slides vertically downward to fit the book core. The second detection member 723 is arranged above the conveyor belt 721 and is located at the starting end of the conveyor belt 721. The book delivery component 71 is located on the side of the placement table 61 and is arranged side by side with the book pushing mechanism 60. When the book pushing lever 63 pushes the book core horizontally, the book core is conveyed to the direction close to the clamping mechanism 70.
