Description

Technical Field

[0001] The present invention relates to a paper processing method and equipment, in particular to a multi-machine printing and post-printing processing online production process and equipment. Background Art

[0002] Using roll paper and rotary printing for printed forms offers high production efficiency and reliable quality, making it a common method for producing printed forms. After printing, rotary presses can simultaneously process feed holes, divider lines, and fold lines, as well as fold and cut sheets. After folding, sheets can be divided into fixed volumes, and then undergo post-press processes such as shrink wrapping, boxing, and packaging to form finished products. After cutting, sheets are vibrated and stacked, divided into semi-finished products before being sent for post-press processing. Post-press processing varies depending on product specifications, with the following common processes: First, for single-sheet finished products, a slitter removes excess material, followed by shrink wrapping, boxing, and packaging; second, for coverless finished products, a slitter removes excess material from the spine, then glues, separates the sheets, trims the other three edges, shrink wraps, boxes, and packaging; and third, for cover-bound books, a slitter removes excess material from the spine, then glues, separates the sheets, binds, trims the other three edges, shrink wraps, boxes, and packaging. The production equipment in the above process is shared. The current situation is that after each process is completed, the semi-finished products are transported to the next process for production. If the products of the above specifications are produced at the same time, the workshop production scheduling will be complicated, the semi-finished products will be piled up, the labor cost will be high, and the production cycle will be long.

DETAILED DESCRIPTION

[0041] In order to make the implementation objectives, technical solutions and advantages of the present invention more clear, the present invention will be described in detail below in conjunction with the accompanying drawings by way of embodiments.

[0042] Example 1, as shown in Figure 1, is a process flow chart of multi-machine printing and post-press processing for producing single and book-type products. Figure 3 The production equipment layout shown in the figure shows the production process as follows:

[0043] 100 Printing and cutting into single sheets: Multiple printing presses 1 perform rotary printing simultaneously, with each printing press 1 printing forms, cutting the forms into single sheets for output, and marking the sheets according to the set number of pages. Here, multiple printing presses 1 produce simultaneously, and the products produced by each printing press 1 may be of the same or different specifications. Since it is rotary printing, roll-type base paper is used, which has high printing efficiency. After printing, the cross-cutting device on the printing press 1 is used to cut the continuous paper into single sheets of semi-finished products. The cutting and printing are synchronized, with high precision, which is particularly suitable for multi-part products that require high overlap of upper and lower table lines.

[0044] 200 Stacking and Booklet Sorting: Single semi-finished products are stacked neatly through vibration and sorted into large books according to booklet markings. Booklet sorting is based on the thickness required for the subsequent trimming process. Generally, large books are multiples of the thickness of the finished small books. This booklet sorting method uses the counting feedback signal from the printing press 1 to control the paper stop device to intercept the paper and prevent it from entering the vibrating paper delivery table 2. At the same time, it sends a signal to the robot 3 to grab the paper.

[0045] 300 Transfer and Conveying: The neatly stacked semi-finished products are conveyed to the predetermined position of conveyor belt I3 or conveyor belt II4 by robot arm 3; this predetermined position refers to the set position where the semi-finished products are placed on the conveyor belt. Since multiple printing machines 1 are used for printing at the same time, the products produced by each printing machine 1 may be of the same specification or different specifications. Therefore, two conveyor belts are used in parallel. Before production, the position where the semi-finished products of each printing machine 1 are placed can be set according to the specifications of the products.

[0046] 400 Fixed-batch conveying: When the number of semi-finished products coming out of each printing machine 1 on conveyor belt I3 or conveyor belt II4 reaches the set number of copies, conveyor belt I3 or conveyor belt II4 starts to convey the semi-finished products to the next process; the setting of this number of copies is determined based on the number of copies that can be trimmed simultaneously by the paper cutter I7 of the next process, that is, the set number of copies is equal to the number of copies cut side by side. For example, if the paper cutter I7 can cut four copies side by side at the same time, then the number of copies is four, and the semi-finished products conveyed to the trimming process each time are four copies.

[0047] 500 Edge trimming: Use paper cutter Ⅰ7 to cut off the excess edge of the semi-finished product according to the required size of the product to make the edge smooth.

[0048] 600. Divide into small books: Divide the large book into small books according to the bookmarks marked by the printing machine 1, that is, divide the books on the transition table 6 according to the number of pages required for the finished product, and put the divided books into the laminating machine II 16.

[0049] 700 Shrink film: Small products are wrapped in heat shrink film using the laminating machine II 16. This laminating machine II 16 has the functions of automatic conveying, laminating, cutting and heating the shrink film.

[0050] 800 Packing: Pack the shrink-wrapped products into boxes according to the number required by the customer.

[0051] 900 Packing: Pack the products with strapping tape on the baler 15 according to the number of boxes required by the customer. Different products are packed in different quantities. Some are packed with strapping tape per box, some are packed with strapping tape two boxes, and some are packed with strapping tape three boxes. After the packing is completed, it can be stacked on the stacking rack and stored in the finished product warehouse.

[0052] After the above production process, single-sheet printed forms are produced without binding. From the time the base paper enters the printing press to the final packaged product, there is no backlog of semi-finished products or manual transportation in between, eliminating process waiting time and improving production efficiency.

[0053] In the second embodiment, based on the first embodiment, the processes from 100 to 400 are the same. In the trimming process at 500, the paper cutter I7 is used to cut off the excess part of the spine edge of the semi-finished product according to the required size of the product to make the edge flat. Each semi-finished product is placed on a flatbed cart 9 and pushed onto the conveyor belt III8 for rear transportation. Since the flatbed cart 9 has four small wheels below, it is very convenient to push it, and then enter the following process:

[0054] 510 Glue brushing: Brush a layer of quick-drying glue on the spine and use conveyor belt III8 to transport it backward. This glue is generally water-based glue, which is environmentally friendly and dries quickly. After drying, the products can be glued together and the paper will not be damaged after tearing.

[0055] 600. Divide into small books: Drag the glued product onto the book dividing table 10, and divide the large book into small books according to the book dividing marks marked by the printing machine 1, that is, according to the number of pages required for the finished product.

[0056] 650 Trimming the three edges: Use the paper cutter II 11 to trim the excess portions of the three edges except the spine edge according to the finished product size requirements to form the finished product. The subsequent processes 700 to 900 are the same as those in the first embodiment.

[0057] After the above steps, a coverless, easily-tearable, glue-bound, booklet-style printed form is produced. From the time the base paper enters the printing press to the final packaged product, as in the previous embodiment, there is no backlog of semi-finished products or manual transport, eliminating waiting time and improving production efficiency.

[0058] Example 3: Based on Example 2, steps 100 to 600 are the same, and the following steps are further implemented:

[0059] 620 Glue Binding: The separated booklets, or cores, are transported via conveyor belt IV 19 to the inlet of the binder 20. The binder 20 then bonds the covers and cores together using hot-melt adhesive. This binder 20 can be either oval or linear, with automatic cover feeding and stacking capabilities. Hot-melt adhesive is typically used for bonding, which provides a more secure core. The bound products are stacked according to the set number of books and transferred to the paper cutter II 11 via conveyor belt V 21.

[0060] The subsequent steps 650 to 900 are the same as those in the second embodiment.

[0061] After the above steps, a printed form with a perfect cover is produced. From the entry of the base paper into the printing press to the final packaged product, as in the previous embodiment, there is no backlog of semi-finished products or manual transportation, eliminating waiting time and improving production efficiency.

[0062] Example 4, as shown in the attached Figure 3The embodiment shown is a process flow chart of multi-machine printing and post-press processing online production of folding form printing products, which also uses the attached Figure 3 The production equipment layout shown is as follows:

[0063] 101 Printing and folding: Multiple printing presses 1 rotate and print simultaneously. Each printing press 1 performs the following processes: printing forms, punching feed holes, punching equal dividers, punching fold lines, marking the pages according to the number of pages required for the finished product, and folding the pages to produce a folded semi-finished product. Here, multiple printing presses 1 produce simultaneously, and the products produced by each printing press 1 may be of the same or different specifications. This type of printing press 1 has the functions of both folding and cutting individual sheets, so the only requirement is to change the processing mode of the printing press 1.

[0064] 201 Stacking and sorting: The folded continuous products coming out of the printing machine 1 are stacked by the semi-finished products on the rear baffle, and the sorting is done according to the sorting mark. Here, the sorting is done according to the number of pages required for the finished product.

[0065] 300 Transfer and conveying: The neatly stacked semi-finished products are conveyed to the predetermined position of conveyor belt I3 or conveyor belt II4 by the robot 5.

[0066] 400 Fixed copy conveying: When the number of semi-finished products coming out of each printing machine 1 on conveyor belt Ⅰ3 or conveyor belt Ⅱ4 reaches the set number, the conveyor belt starts to transport the semi-finished products to the next process.

[0067] 601 Arrangement: The products are manually arranged on the transition table 6 and put into the laminating machine II 16 according to the number of books at a time.

[0068] 650 Pressing: Use the pressing device 17 on the laminating machine II 16 to press the semi-finished product once. Since the folded semi-finished product is naturally warped and loose at the folded edge, it is easy to deform the product when shrink film is passed through. It is necessary to press the warped part of the folded edge to reduce the warping and facilitate smooth film passing.

[0069] 700 Shrink film: The product is wrapped with heat shrink film through the laminating machine Ⅱ16.

[0070] 800 Packing: On the packing table 18, the products wrapped with shrink film are packed into packaging boxes according to the number required by the customer.

[0071] 900 Packing: Pack the boxes in the number required by the customer using strapping machine 15.

[0072] After the above production process, the folding form printing product is produced. From the raw paper entering the printing press to the final packaged product, there is no backlog of semi-finished products and manual transportation in between, eliminating process waiting time and improving production efficiency.

[0073] As attached Figure 3 The figure shows the production equipment layout for implementing the production processes of the above-mentioned embodiments 1 to 4. By adopting this equipment layout, a variety of production methods can be formed, different production processes can be realized, and products of various specifications can be produced. The detailed implementation examples are described below.

[0074] Example 5. This production equipment is divided into a front section and a rear section. The front section includes multiple printing machines 1 installed side by side. A vibrating paper collection platform 2 is connected to the head of each printing machine 1. A conveyor belt I3 and a conveyor belt II4 of the same size are installed side by side behind the vibrating paper collection platform 2. A robot 5 is also installed on the vibrating paper collection platform 2, conveyor belt I3 and conveyor belt II4. The length of conveyor belt I3 and conveyor belt II4 runs through all printing machines 1. The rear section includes a transition platform 6 connected to the tail ends of conveyor belts Ⅰ3 and conveyor belts Ⅱ4. The left side of the transition platform 6 is connected to one side of a paper cutter Ⅰ7. The other side of the paper cutter Ⅰ7 is connected to the conveyor belt Ⅲ8 at a right angle. There are multiple flatbed trucks 9 placed on the conveyor belt Ⅲ8. The right side of the conveyor belt Ⅲ8 is connected to a distribution platform 10. The tail end of the conveyor belt Ⅲ8 is connected to one side of the paper cutter Ⅱ11 at a right angle. The other side of the paper cutter Ⅱ11 is connected to an operating table 12. The operating table 12 is connected to the inlet of the laminating machine Ⅰ13. The outlet of the laminating machine Ⅰ13 is connected to a packing table Ⅰ14. There is a baling machine 15 behind the packing table Ⅰ14.

[0075] In this embodiment, the front section also includes an electrical control system, comprising a control box 51, a position detection sensor 52 mounted on the robot 5, a position sensor 53 mounted on conveyors I3 and II4 corresponding to each printing position, an accumulation sensor 54 mounted at the tail of conveyors I3 and II4, and a start button 55 and a stop button 56 mounted on the side of the tail end of conveyor I3. Control box 51 is electrically connected to the other components and houses the components that control the automatic operation of conveyors I3 and II4, including a setting keyboard, display, and alarm. Operating parameters can be set on control box 51. This electrical control system controls conveyor belt I3 and conveyor belt II4 to operate automatically and efficiently: the feedback from the position detection sensor 52 controls the robot 5 to accurately place the product on the specified position of conveyor belt I3 or conveyor belt II4, the number of products placed is detected by the location sensor 53 to control the operation of conveyor belt I3 or conveyor belt II4, and the feedback from the location sensor 54 controls whether conveyor belt I3 or conveyor belt II4 is started. When there is a backlog of products on the conveyor belt, causing a certain workstation to fail to operate normally, an alarm will be used to prompt.

[0076] According to this equipment technical solution, the process flow of the aforementioned embodiment 2 can be implemented to produce easy-to-tear, glue-bound, cover-less, book-style form printing products.

[0077] In Example 6, in the aforementioned Example 5, the rear section further includes a laminator II 16 connected at right angles to the right of the transition table 6. A pressing device 17 is mounted on laminator II 16. The outlet of laminator II 16 is connected to a boxing table II 18, which is then followed by a baler 15. This equipment solution allows for simultaneous use of the paper cutter I 7 for in-line production, enabling the production processes of Examples 1 and 4 to be implemented, producing unbound single-sheet and folding form printed products.

[0078] In Example 7, in Example 5 above, the upper end of the sub-table 10 is further connected to a conveyor belt IV 19, which is connected to the inlet of a perfect binder 20. The outlet of the perfect binder 20 is connected to a conveyor belt V 21, and the rear end of the conveyor belt V 21 is connected to the paper cutter II 11. This equipment connection allows the production process of Example 3 above to be implemented, producing a book-style form printed product with a perfect cover.

[0079] The paper cutter I7 and paper cutter II11 described in the above embodiment adopt program control to adjust the paper cutting specifications and sequence, and can quickly switch models to produce different products.

[0080] All conveyor belts described in the above embodiments comprise a flat belt, a support, and a power system. During operation, products can be placed directly on the flat belt, which then drives the products forward. The power system of conveyor belt I3 or conveyor belt II4 is controlled by a front-end electrical control system. Conveyor belts III8, IV19, and V21 also have their own independent control systems, which are manually started and stopped, and controlled by induction switches during operation. Specifically, conveyor belts start when products are present and automatically stop when no products are present or when products accumulate at the exit.

[0081] It can be seen that according to the arrangement of the above-mentioned production equipment, all equipment can be started at the same time for production according to production needs, that is, multiple production processes can be carried out simultaneously.

[0082] The technical solution of the present invention uses common materials, is suitable for industrial production, and is feasible and practical.
