Description

Technical Field

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

[0002] As demand for books continues to grow, automated bookbinding equipment is becoming increasingly sophisticated. Text is digitally printed onto a roll, which then passes through automated bookbinding equipment, where it undergoes folding, cutting, gluing, stacking, and wrapping, resulting in a successfully bound book.

[0003] In existing roll-to-roll digital printing, book pages are folded and cut into signatures. During the high-speed conveyance of signatures and their stacking into book blocks, vibrations or shocks can cause them to shift or become unstable, resulting in inaccurate alignment during stacking. Furthermore, the speed of the conveyor belt and the movement of the stacking device may not be coordinated, so signatures may not have enough time to be accurately positioned when they are delivered to the stacking position, resulting in uneven stacking. To address this issue, it has been proposed to reduce the conveyor speed so that the equipment can spend more time accurately positioning the signatures.

[0004] However, the above technical solution reduces the transmission speed of the book pages, which takes more time to stack the book sheets, which greatly reduces the production efficiency of the book. Therefore, there is a need for a digital printing book sheet stacking device that can accurately stack the book sheets without reducing the transmission speed of the book sheets.

[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 can be directly connected to the other component or there may be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and similar expressions used herein are for illustrative purposes only.

[0076] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0077] Before we get into the details, it's important to note that this device is used in high-speed bookbinding equipment, and the binding process for high-speed bookbinding equipment is as follows:

[0078] The printed paper roll is placed in the unwinding device and unwound to form a continuous paper strip. (The printed paper roll is: Using high-speed digital printing equipment, multiple pages can be printed simultaneously on a continuous web, ensuring efficient production.)

[0079] To facilitate the subsequent shaping of the book, the paper roll is folded along its width. This folding process can be understood as arranging the pages in the order they will eventually be needed for the book, making it easier to bind the pages.

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

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

[0082] See also Figure 1-Figure 22 Specifically, the upper and lower conveyor belts 11 and 12 slide in a conveying direction F1. Signatures are arranged in a fish-scale pattern and conveyed between the upper and lower conveyor belts 11 and 12. The upper and lower conveyor belts clamp the signatures and continuously convey them along the conveying direction F1. The path along which the upper and lower conveyor belts convey the signatures forms a conveying area 13. The fish-scale pattern of signatures allows for more efficient conveying.

[0083] The upper and lower conveyor belts 12 are equipped with tensioning pulleys and equidistant guide pulleys in the direction of their sliding motion. The tensioning pulley is typically mounted at a fixed or adjustable position on the conveyor belt, adjusting the belt tension through a mechanical device (such as a spring or pneumatic device). During the conveyor belt's operation, the tensioning pulley dynamically adjusts based on the actual belt condition to ensure the appropriate belt tension is maintained.

[0084] Guide rollers are typically installed at specific locations along the conveyor path, particularly where the belt is prone to deviation or requires additional support. Precisely calculated guide roller locations ensure the conveyor belt remains on its designed path, avoiding deviation or slack at high speeds.

[0085] The signatures are conveyed into the conveying area 13 , where 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 signature first passes through the detection component 30, and the book signature camera 31 captures the book signature content (such as the printed QR code and the number of book signature pages) on the book signature to generate a book signature signal. Among them, when the printed content is incomplete, the counting sensor 32 detects the number of book signatures clamped and conveyed by the upper and lower conveyor belts 12. The upper and lower conveyor belts 12 clamp and convey the book signature so that the book signature will not fall off the conveyor belt due to the weight of the book signature during high-speed transmission, making the counting sensor 32 more accurate, and the book signature is fixed between the upper conveyor belt 11 and the lower conveyor belt 12, so that the book signature camera can accurately capture the book signature content printed on the book signature.

[0087] The 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 signatures in the conveyor belt.

[0088] After glue application, the signatures pass through the sorting mechanism 50, which is electrically connected to the detection assembly 30 to receive a sorting signal. Upon receiving the sorting signal, the rotating shaft connected to the electromagnet 51 rotates, driving the hook plate 52 connected to the rotating shaft downward until it contacts the signature, separating it from the previously transferred signature. If the sorting mechanism 50 does not receive the sorting signal, it remains inoperative. The glued signatures are then transferred to the stacking area 23, which is connected to the transfer area 13.

[0089] The book receiving and stacking mechanism 20 (including the plurality of limit assemblies and the book receiving assembly 22) and the book pushing mechanism 60 are sequentially arranged along the guide direction F2, which is perpendicular to the conveying direction F1 and arranged downward. 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] The plurality of limiting components 21 are provided according to the number of edges of the signature.

[0091] In one embodiment, the book is rectangular with four edges. After glue application, signatures are transported from the book exit end of the upper conveyor belt 11 to the stacking area 23. The front, rear, left, and right limiting assemblies 214 are positioned in advance so that one limiting assembly fits one edge of the signature, and four limiting assemblies enclose the four edges of the signature. Each limiting assembly is provided with a book receiving conveyor belt 2112. The book receiving conveyor belt 2112 fits the signature and, when the book receiving conveyor belt 2112 slides along the guide direction F2, it drives the signature to slide along the guide direction F2 to the book receiving assembly 22, forming a book receiving platform 2212. The signatures are then stacked on the book receiving platform 2212, and multiple signatures, when stacked, form a book block.

[0092] The four limiting components are enclosed and glued together 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 limiting components prevent the signatures from being misplaced or slipping during transport, keeping them neatly arranged. This is crucial for the smooth progress of the subsequent stacking process.

[0094] The four limiting assemblies 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 assemblies 214 to stabilize the position of the signature.

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

[0096] The rear stop 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 limiting assembly 213 and the right limiting 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 signature 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 signatures are delivered to the stacking area 23 , the limiting components will automatically adjust their positions to fit the four edges of the signatures to provide an enclosed frame to prevent the signatures from tilting or sliding during the stacking process.

[0100] During the stacking process, the stoppers not only secure the signatures but also ensure vertical alignment by enclosing their edges. This means that each signature remains horizontal when stacked, without shifting or overlapping, thus forming a neatly arranged book block.

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

[0102] The receiving conveyor belt 2112 is part of the stopper assembly, which fits over one edge of the signature to further ensure that the signature remains stable during transport. The receiving conveyor belt 2112 guides the signature from the conveyor belt to the stacking area 23 and helps it slide into the correct position once it enters the stacking area 23, preventing it from getting stuck or shifting during the final stages of transport.

[0103] The front stop assembly 211 is connected to the lower conveyor belt 12 and is located at the book exit end of the conveyor area 13. The book receiving conveyor belt 2112, attached to the front stop assembly 211, is formed by bending the lower conveyor belt along the guide direction F2. One edge of the signature is in contact with the conveyor belts (the upper and lower conveyor belts and the book receiving conveyor belt 2112) before being stacked, ensuring the transition of the signatures from the conveyor area 13 to the stacking area 23.

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

[0105] The receiving conveyor belt 2112 is bent along the guide direction F2, which changes the horizontal transport of signatures to vertical transport, guiding the signatures gradually into the stacking area 23. The guide direction F2 is perpendicular to the main transport direction F1. This bending structure ensures that the signatures change their transport path at the end of the conveyor belt and enter the stacking area 23 accurately without deviation or misalignment.

[0106] The bent book receiving conveyor belt 2112 fits one edge of the signature, playing a role in precise positioning. The bending structure ensures that the signature always maintains contact with the book receiving conveyor belt 2112 and moves smoothly along the conveying direction F1, preventing the signature from shifting left or right 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 signatures are aligned before stacking, so that each signature maintains a consistent direction, providing an accurate basis for subsequent stacking.

[0108] A limiting assembly, coupled with a book-receiving conveyor belt 2112 and aligned with one edge of the signature, precisely controls the delivery of the signature in the guide direction F2, ensuring that each signature is stacked along the predetermined path and sequence. This prevents uneven or tilted stacking and improves stacking accuracy and quality.

[0109] During the process of the signature being delivered to the receiving platform 2212, the receiving conveyor belt 2112 continuously slides to push the signature to the correct position, ensuring that the signature will not tilt or be stacked unevenly when stacked. Each signature is stacked smoothly under the guidance of the receiving conveyor belt 2112.

[0110] The book receiving conveyor belt 2112 ensures a smooth transition of signatures as they are transported to the stacking area 23, preventing them from being misaligned or slipping due to inertia or friction. This improves the stability and accuracy of signature stacking, ensuring that signatures are clearly layered and neatly aligned during stacking, and reduces production problems caused by uneven stacking.

[0111] In practice, the various components of the entire limiting assembly are tightly connected, forming a system for automatic adjustment, limiting, and precise stacking. The fixed plate 2111 provides the basic limiting structure, enclosing the book sheets and ensuring they do not shift during stacking. The book receiving conveyor belt 2112 is responsible for accurately transporting the book sheets to the stacking area 23. The vibrating element 2113 fine-tunes the book sheets through vibration to ensure that each layer is neatly stacked. The adjustment motor 2114 and the sliding element 2115 work together to dynamically adjust the position of the fixed plate 2111 according to the different sizes of the books, ensuring that the equipment can handle books of various sizes.

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

[0114] In a specific embodiment, the digital printing signature stacking device 100 further includes a book pushing mechanism 60, which comprises a placement platform 61, a slide rail 62, a book pushing lever 63, and a cam member 65. The placement platform 61 is located below the book receiving platform 2212 and receives book blocks. The slide rail 62 is fixed below the placement platform 61. The book pushing lever 63 is slidably connected to the slide rail 62, with one book pushing lever 63 slidably connected to one slide rail 62, and the other book pushing lever 63 slidably connected to the other slide rail 62. A pushing motor 64 is connected to the book pushing lever 63, generating 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 retracting force. One cam member 65 is connected to one slide rail 62, and the other cam member 65 is connected to the other slide rail 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 platform 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 placement table 61 receives the book block, the push motor 64 drives the book push lever 63 to slide on the slide rail 62, pushing the book block to the next station. After the book push lever 63 completes its pushing action, the cam member 65 acts on the book push lever 63 to reset it. Each feature plays a key role in ensuring the precise and rapid pushing of the book block. A set of push lever power devices are located on each side of the placement table 61. When one push lever 63 is driven to push the book, the other push lever 63 is driven to reset, and the two push levers 63 achieve alternating pushing action.

[0117] In a specific implementation, the digital printing signature stacking device 100 further includes a pressing 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. The pressing mechanism 70 includes:

[0118] The book discharging assembly 71 is arranged side by side with the placement table 61. 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 provided 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. The function of the book delivery component 71 is to receive the book core and convey it to the clamping mechanism 70 for clamping.

[0121] The first detection member 712 is located on the side of the book delivery conveyor belt 711 and is responsible for detecting whether the book block has reached the specified position. Its function is to monitor the status of the book block in real time. When the book block passes, the detection member will trigger subsequent operations, such as starting the pressing assembly 72.

[0122] The pressing assembly 72 is located next to the book output assembly 71 and is arranged side by side with the conveyor belt 721. Its main function is to perform vertical pressing on the book blocks conveyed to the pressing position to ensure that the book blocks are compacted and flat, providing conditions for subsequent stacking or binding.

[0123] The second detection member 723 is located at the starting end of the conveyor belt 721 and is responsible for detecting whether the book block has been compacted and is ready for the next step of transmission.
