Description

Technical Field

[0001] The invention relates to an online processing system for sheet materials, belonging to the technical field of financial equipment. Background Art

[0002] Banknote printing plants and other organizations face a large volume of banknote processing, and banknote bundling is a crucial component, shouldering the heavy responsibility of ensuring both digital security and product packaging quality. Currently, widely used bundling equipment suffers from several issues: First, it's impossible to adjust bundles on demand during the bundling process, resulting in significant height differences between the two sides of the bundled banknotes, making storage difficult and impacting subsequent operations. Second, the bundling tightness can't be adjusted in real time, resulting in inconsistent tightness between bundles, creating the risk of looseness (too loose) and breakage (too tight), leading to various security issues. Third, the bundling process involves only one strap, which can be unsafe and potentially prone to scattering. Fourth, most bundling equipment is individually configured, occupying a large footprint and spanning a large production line.

[0003] In existing technology, bundling equipment is primarily categorized as separate and integrated. Separate bundling equipment utilizes separate devices, including the sorter, collector, and strapping equipment. This production approach presents drawbacks: Each device is independently configured, resulting in long production lines and a large footprint. Power and control systems require independent setup, leading to a complex system. Bundles are exposed to the conveyor belt, posing a digital safety risk. Furthermore, products from various small bins are mixed during transport, preventing independent bundling in each bin. The shortcomings of integrated bundling equipment are: it cannot realize the on-demand U-turn of hundreds of packages; it does not have the function of sorting hundreds of packages, and the neatness of the bundled thousands of packages is poor; the bundling tightness of the products is fixed during the bundling process and cannot be adjusted adaptively according to the products; the tightness of the bundled thousands of packages is inconsistent, and the failure rate of looseness and broken straps in actual applications is very high, which reduces production efficiency and affects the digital security of products; the equipment does not have an integrated labeling function, and the product labeling action is completed by a separate device; the bundled products are freely transported from the previous conveyor belt to the labeling equipment, and under certain abnormal conditions, the product barcode and the actual product may be mismatched. In the bundling equipment in the above layout, the bundling mechanisms of different hundreds of packages are designed as a whole, which is inconvenient to separate from each other and is not conducive to flexible configuration according to actual needs.

[0027] The technical content of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] In one embodiment of the present invention, an online processing system for sheet materials is provided, which is configured to interface with various types of sorting machines and perform a U-turn and bundle operation on the 100-sheet packages delivered by the sorting machines. The packages are then delivered by the bundling module 200 and the output conveyor 300. Because the thickness of the two sides of the sheet material is different, a quantitative U-turn is required when bundling the packages. For example, the metal security thread of the RMB is located on one side of the long side of the RMB (not on the line of symmetry along the long side). Therefore, when 100 RMB notes are stacked together to form a bundle, the side with the security thread is significantly thicker than the side without the security thread. Therefore, when bundling, the direction of the bundles needs to be changed every five bundles (i.e., the security thread of the first five bundles is on the left, and the security thread of the last five bundles is on the right) before the bundles are bundled together. Therefore, the online processing system for sheet materials provided by the embodiments of the present invention needs to have a function that enables the sheet materials to be automatically U-turned.

[0029] For ease of understanding, Figure 1 A schematic diagram of the structure of a sorting machine interfaced with the above-mentioned online processing system for sheet materials is provided. The sorting machine 100 includes a sorting module and a bin; the bin of the sorting machine 100 is connected to the bundling module 200. The sorting machine 100 is used to sort banknotes and notes, bundle the sorted banknotes into bales, and transport them to the bin for storage. The bundling module 200 is connected to the bin of the sorting machine 100 to receive the bales stored in the bin, adjust and aggregate the bales, and generate bales. The transmission head end of the output conveyor belt 300 is connected to the bundling module 200 to output the bales conveyed by the bundling module 200.

[0030] After bundling, labeling can also be performed. Labeling involves attaching a barcode or QR code to the bundled packages, or printing information about the package and individual packages (including plain text or encrypted QR codes) on the paper pad. Label input involves the system reading the package identifier and linking it with the corresponding package information, such as clearing information, denomination and total amount, and serial number, and uploading it to the management system. Output involves transporting the bundled packages to the conveyor belt for subsequent processing.

[0031] In one embodiment of the present invention, Figures 2 to 5 As shown, the bundling module 200 includes a frame 210, a lifting component 211, a centering component 212, a rotating component 213 and a limiting component 214, wherein: the lifting component 211 and the limiting component 214 are fixed on the frame of the bundling module 200, the rotating component 213 and the centering component 212 are attached to the lifting component 211, and the rotating component 213 and the centering component 212 move synchronously with the lifting component 211 in the vertical direction.

[0032] Lifting assembly 211 is used to adjust the vertical position of the bag and includes a lifting power source 2110 and a support plate 2111. Lifting power source 2110 is fixed to frame 210, allowing support plate 2111 to rise as lifting power source 2110 extends and descend as lifting power source 2110 contracts. Support plate 2111 is located below bag adjustment plate 1, and the two are configured to rotate relative to each other.

[0033] The centering assembly 212 is used to adjust the horizontal position of the bag and includes a pair of centering plates 2122 and a centering power source (not shown). These plates are mounted on either end of the bag adjustment plate 1 and above the support plate 2111. The centering plates 2122 are configured to rotate with the bag adjustment plate 1. The centering plates 2122 are configured to move relatively farther or closer to each other under the power of the centering power source.

[0034] The limiting assembly 214 is used to adjust the horizontal position of the bag and includes a limiting power source 2141 and a limiting plate 2142. The limiting plate 2142 is located on one side of the bag adjustment plate 1. Specifically, the two centering plates 2122 and the limiting plate 2142 are located on three sides of the bag adjustment plate 1, forming a C-shaped limiting structure to position the sheet material above the bag adjustment plate 1 in two dimensions in the horizontal direction.

[0035] The rotating assembly 213 is used to realize the 180° turn-around of the bag. The rotating assembly 213 is fixed on the frame 20 and is configured to drive the bag adjustment plate 1 to rotate relative to the supporting plate 2111.

[0036] The external push assembly 215 includes an external push force source 2151 and a push rod 2152. The push rod 2152 is located on one side of the baibao adjustment plate 1 and, along with the stop plate 2142, on opposite sides of the baibao adjustment plate 1. Therefore, the push rod 2152, the stop plate 2142, and the two centering plates 2122 are located on the four sides of the baibao adjustment plate 1, surrounding the baibao adjustment plate 1. However, the push rod 2152, the stop plate 2142, and the two centering plates 2122 are located on different horizontal planes. The three side edges of the Baibao adjustment plate 1 in the waiting position are in contact with the limit plate 2142 and the two centering plates 2122, but are not coplanar and in contact with the push rod 2152 (the Baibao adjustment plate 1 is higher than the push rod 2152); the two opposite side edges of the Baibao adjustment plate 1 in the high position are in contact with the two centering plates 2122, but are not in contact with the limit plate 2142 or the push rod 2152 (that is, the Baibao adjustment plate 1 is higher than the limit plate 2142 or the push rod 2152); the three side edges of the Baibao adjustment plate 1 in the low position are in contact with the two centering plates 2122 and the push rod 2152 respectively, but are not in contact with the limit plate 2142 (that is, the Baibao adjustment plate 1 is lower than the limit plate 2142). In other words, the push rod 2152 is lower than the limit plate 2142, and the two centering plates 2122 can be raised and lowered along with the supporting plate 2111 at two positions higher than the limit plate 2142 or not lower than the limit plate 2142.

[0037] In one embodiment of the present invention, the left and right saddle adjustment assemblies are symmetrically arranged. In the initial position, the lifting power source is retracted, the saddle adjustment plate 1 is in the waiting position, the centering power source is extended, the limit power source is extended, the limit plate is aligned with one side of the saddle adjustment plate 1, and the external driving power source is extended.

[0038] The workflow is as follows: Figure 2 As shown, the Baicang of the sorting machine 100 will push the Baibiao 400 onto the Baibiao adjustment plate 1 (which is in the waiting position at this time) to reach a position where the Baibiao 400 is blocked by the limit plate 2142 (at this time the limit power source 2141 is extended, and the limit plate is located on the side of the Baibiao adjustment plate 1 opposite to the sorting machine 100).

[0039] like Figure 3 As shown, if the bag 400 needs to turn around, the lifting power source 2110 extends, driving the support plate 2111 to push the bag adjustment plate 1 upward to a high position (above the waiting position). Simultaneously, the centering power source 2121 retracts to complete the centering of the bag 400, and the bag 400 is clamped in place by the centering assemblies 2122 located at both ends of the bag adjustment plate 1. The limiting power source 2141 retracts, causing the limiting plates 2142 to move away from the bag adjustment plate 1.

[0040] like Figure 4As shown, the rotation power source 2131 rotates 180 degrees, causing the bag adjustment plate 1 to rotate accordingly. The centering assembly 2122 installed on the bag adjustment plate 1 keeps the bag 400 clamped during the rotation process and also rotates accordingly.

[0041] like Figure 5 As shown, after the rotary power source 2131 rotates the bag adjustment plate 1 180 degrees (i.e., the bag 400 has been turned around), the lifting power source 21 retracts, causing the bag adjustment plate 1 to drop to the low position (lower than the waiting position). The low position is coplanar with the transition fork 20.

[0042] like Figures 6 to 8 As shown, after the bag adjustment plate 1 descends to its lowest position, the centering power source 2121 extends, causing the centering assembly 2122 to open and release the bag 400. The external driving force source 2151 drives the push rod 2152, pushing the bag 400 toward the buffer fork 20. Once the bag 400 is pushed onto the buffer fork 20, it is delivered to the workstation of the bag stacking assembly. The power sources are then reset, completing the processing flow for one bag.

[0043] The lifting assembly 211 cooperates with the structural parts and the power source to form a limit block to realize the position adjustment of the assembly in the vertical direction, so as to provide the large space required for the bag to rotate after it rises to a high position; the centering assembly 212 can realize the adjustment of the position of the bag in the horizontal direction, ensuring that the bag will not shift during the rotation process. Since the bag can be of different specifications (for example, the specifications of 100 yuan banknotes and 10 yuan banknotes are different), the positions of the bag conveyed by the sorting machines of different specifications are not uniform. Therefore, this assembly, combined with the lifting assembly 211 and the centering assembly 212, can be connected to various specifications of sorting machines and process various specifications of bag, with a wide range of applications and strong passability. Therefore, the system of the present invention reduces the number of equipment configurations, reduces the equipment installation space, and has a better overall layout. The bag is bundled inside the equipment, avoiding the bag being exposed on the conveyor belt, and digital security is further guaranteed. The above system only retains the conveyor belt for conveying bags, reducing the number of conveyor belts.

[0044] In one embodiment of the present invention, the driving element is mainly a cylinder or a motor. Here, the cylinder is used as an example for description, but this does not constitute a limitation.

[0045] In one embodiment of the present invention, the working process of the bundle module 200 is as follows: the bag conveying component delivers the bag stack to the specified position on the bag pallet, the bag pressing component rises to the specified height to lift the bag stack, the conveying component resets, the bag pressing component continues to rise until the top plate pre-pressure sensor is triggered, the transverse and longitudinal belt groove components move outward to form transverse and longitudinal closed belt grooves, the transverse and longitudinal belts are threaded, the bag pressing component continues to rise to press, the transverse and longitudinal belts are retracted and tightened, the transverse and longitudinal belt groove components retract to the initial position, the ironing component completes the ironing and cutting of the belts, the bag conveying component's outward-turning electric cylinder rotates inward, the bag pressing component descends, and the bundled bag falls on the bag output tray, the bag conveying component's outward-turning electric cylinder rotates outward, driving the bag to fall sideways on the bag pallet, the side-turning electric cylinder rotates a specific angle, and the bag slowly slides down.

[0046] In one embodiment of the present invention, the labeling motor on the labeling and code reading module rotates to drive the lower end of the labeling paper to stick to the bag, and the smoothing brush smoothes the label stuck to the bag and increases the adhesion strength. The bag continues to slide down, the code reader completes reading the label information and uploads it to the system, and the bag continues to slide down to the conveyor belt and is transported to the next process.

[0047] In one embodiment of the present invention, the lifting assembly 211 of the bundle adjustment assembly 210 of the bundling module 200 also includes a first-level cylinder and a second-level cylinder. The first-level cylinder and the second-level cylinder are vertically fixed on the frame of the bundling module 200, and the first-level cylinder and the second-level cylinder are used to drive the lifting assembly 211.

[0048] In one embodiment of the present invention, the bale centering assembly 220 of the bundling module 200 includes a transverse centering mechanism and a longitudinal centering mechanism, which are used to adjust the position of the bales in the transverse and longitudinal directions respectively to achieve centering of the bales.

[0049] In one embodiment of the present invention, the bundling assembly of the bundling module 200 is used to receive the centered bales output by the bale centering assembly 220 and perform double cross symmetrical bundling on the bales with two horizontal passes and one vertical pass.

[0050] In one embodiment of the present invention, the bundling module 200 adopts an integrated design. First, the bundling function of every two small bins is integrated into one bunkling module 200 (every two small bins correspond to one bin of the sorting machine 100), and is connected to one bin in the sorting machine 100; the bundling modules 200 between bins are independent of each other and can be flexibly configured according to customer needs. This design allows the individual bundling and output of the bales in each small bin. At the same time, the separate configuration of the bins also facilitates operation and maintenance, making it very easy to use. Second, the collection and adjustment of the bales and the arrangement of the bales are integrated into the bundling module 200, and all bundling operations can be completed within the module. In this module, the bales can be accumulated according to the preset quantity, the direction of the bales can be adjusted according to the process requirements, and the bales are automatically arranged and aligned horizontally and vertically before bundling.

[0051] Compared with the existing technology, the online processing system for sheet materials provided by the present invention automates the steering operations in the sorting machine and bundling operations, thereby realizing a comprehensive fully automatic layout of the sorting machine, bundling module and conveyor belt, improving the degree of bundling automation and enhancing digital security.

[0052] The above describes the online processing system for sheet materials provided by the present invention in detail. For those skilled in the art, any obvious changes made to it without departing from the essence of the present invention will constitute infringement of the patent rights of the present invention and will result in corresponding legal liability.
