Description

Technical Field

[0001] This utility model relates to the field of printer technology, specifically a material receiving device for stacking and collecting single-sheet printing media, and a high-speed printer including the material receiving device. Background Technology

[0002] High-speed commercial or industrial printers, as sheet-fed inkjet printing devices, are widely used for large-volume continuous printing of stacked paper (i.e., several sheets of paper stacked together, such as commercially available copy paper and printer paper). In this large-volume continuous printing process, to facilitate subsequent sorting, binding, and other processing, the printed output paper needs to be sorted / copies (hereinafter usually referred to as sorting) according to set requirements during collection. This means that, according to the set classification, the paper is stacked in a staggered manner along the height direction at the paper collection point (staggered stacking is a misalignment in the transverse direction of the paper transport direction). The misalignment distance for staggered stacking is typically 5–20 mm. Figure 16 The laterally staggered stacking medium C is shown. Based on this, the paper delivery section of the aforementioned high-speed printer should have a paper delivery device capable of staggering the printed output paper.

[0003] In the existing technology, there are two main structural forms disclosed regarding misaligned paper delivery and collection devices.

[0004] The first structural form involves arranging a transverse paper-tapping mechanism above a liftable paper receiving platform. This transverse paper-tapping mechanism has a crossbar transverse to the paper conveying direction, with a reference side plate connected to one end of the crossbar and a paper-tapping side plate connected to the other end of the crossbar.

[0005] The process by which this technology performs staggered stacking of papers entering the receiving platform is as follows:

[0006] The reference side plate of the transverse paper-feeding mechanism is positioned at a set reference point on the crossbar. The paper-feeding side plate is pulled away from the reference side plate on the crossbar by a distance sufficient to allow the printed output paper to enter, thus forming a collection channel for the printed output paper. When paper is detected entering the paper receiving platform, the paper-feeding side plate of the transverse paper-feeding mechanism moves axially along the crossbar according to a set stroke, pushing the current paper flat to abut against and align with the reference side plate. This process is repeated, meaning that for each sheet of paper, the paper-feeding side plate needs to perform a return stroke on the crossbar, thus forming the currently set paper stacking unit (i.e., a stack of papers that should be neatly stacked).

[0007] When entering the next set paper stacking unit, the reference side plate of the transverse paper-tapping mechanism is axially displaced on the crossbar according to the setting and positioned at reference point two. The paper-tapping side plate is pulled open on the crossbar and the reference side plate to allow the printed output paper to enter. When paper is detected entering the paper delivery platform, the paper-tapping side plate of the transverse paper-tapping mechanism is axially displaced along the crossbar according to the set stroke, pushing the current paper flat to abut against and align with the reference side plate. This process is repeated to form the current set paper stacking unit.

[0008] This allows the horizontal paper-feeding mechanism to switch back and forth between the set reference point one and reference point two, so as to achieve staggered stacking and collection of different groups of paper-feeding units in the height direction of the paper collection platform.

[0009] It is obvious that the above-mentioned first structural solution has the following main technical problems:

[0010] 1. The horizontal paper feeding mechanism involves a lengthy and time-consuming process of pushing and resetting each printed sheet during the horizontal alignment process. During this process, subsequent paper cannot be received. Therefore, this limits the overall paper transport efficiency of the printer and prevents the printer from achieving high-efficiency paper delivery.

[0011] 2. The latter set of paper stacking units uses the former set of paper stacking units as the stacking support surface. Therefore, during the stacking process of the latter set of paper stacking units on the former set of paper stacking units (especially the initial stacking process of the latter set of paper stacking units), there will be unavoidable reciprocating friction contact between the side plates of the transverse paper-tapping mechanism, especially the paper-tapping side plates, and the former set of paper stacking units. This reciprocating friction contact will cause the stacked paper of the former set of paper stacking units to shift, resulting in poor neatness and obvious messiness of the ultimately misaligned stacked paper.

[0012] 3. There is no travel stop structure at the paper head entering the paper receiving platform. Due to the inertia of the paper being transported and the frictional pushing of the paper entering the paper receiving platform, the alignment of the paper stacked on the paper receiving platform in the transport direction is also obviously poor.

[0013] Therefore, the paper stacking at the paper receiving platform using the above technology exhibits severe disorder both in the conveying direction and laterally.

[0014] The second structural form is exemplified by the technology disclosed in Chinese patent literature, titled "A Misaligned Paper Delivery Mechanism for a Digital Printer," with publication number CN 222757610 U and publication date April 15, 2025. The specific implementation of this technology is as follows:

[0015] The liftable paper delivery platform is configured as a movable structure in the transverse direction corresponding to the paper delivery direction of the printed output;

[0016] Above the paper receiving platform, a conveyor side baffle assembly similar to the aforementioned transverse paper feeding mechanism is arranged. The bottom of the two side plates of the conveyor side baffle assembly has a bent structure that can support the printed output paper.

[0017] A paper-side paper stop assembly is connected to the conveyor side paper stop assembly, located between the two side plates, and used to stop and constrain the sequentially entering paper from the paper head.

[0018] The conveyor side baffle assembly and the paper side baffle assembly together form a temporary storage and stacking mechanism capable of stacking incoming paper.

[0019] The process of misaligned paper stacking on the receiving platform in this technology is as follows:

[0020] S1. The current batch of paper collected by the temporary storage and stacking mechanism is used as a group of paper stacking units. According to the set classification, the temporary storage and stacking mechanism should stack the paper that is currently entering in sequence neatly.

[0021] S2. According to the set classification, after the temporary storage and stacking mechanism completes the current collection, the paper receiving platform moves laterally according to the set stroke.

[0022] S3. The temporary storage and stacking mechanism releases the two side plates of the conveyor side board assembly and places the currently collected stacking paper units on the receiving platform;

[0023] S4. Repeat steps S1 to S3, and by moving the paper receiving platform in different directions in the horizontal direction, the temporary storage and stacking mechanism can stack the paper units collected in different batches in a staggered manner in the height direction of the paper receiving platform.

[0024] It is obvious that the technical solution of the second structural form mentioned above has the following main technical problems:

[0025] 1. The conveyor side baffle assembly that constitutes the temporary storage and stacking mechanism has a long time-consuming action execution process when unloading and resetting each batch of collected and stacked paper units. During this action execution process, subsequent paper cannot be received. Therefore, this limits the overall paper transmission efficiency of the printer and prevents the printer from achieving high-efficiency paper delivery.

[0026] 2. The latter set of paper stacking units uses the former set of paper stacking units as the stacking support surface. Therefore, during the stacking process of the latter set of paper stacking units on the former set of paper stacking units, there will be unavoidable frictional contact between the two side plates of the conveyor side board assembly and the former set of paper stacking units. This frictional contact will cause the stacked paper of the former set of paper stacking units to shift, resulting in poor neatness of the ultimately misaligned stacked paper.

[0027] 3. The paper receiving platform uses lateral translation to achieve staggered stacking of each group of paper stacking units. When the stacked paper on the paper receiving platform is too high, the stacked paper is prone to displacement and collapse during the lateral translation process, which is not conducive to the collection of paper stacks with greater height (larger batch).

[0028] 4. The stacking space of the conveyor side baffle assembly constituting the temporary storage and stacking mechanism does not gradually decrease as paper continues to enter. To accommodate the sequential stacking of paper, there is a significant height difference between the stacking space of the temporary storage and stacking mechanism and the printing output port. The temporary storage and stacking mechanism collects and stacks the paper in sequence by the sequential falling of the printed output paper within the stacking space formed by the conveyor side baffle assembly. Furthermore, there is no paper pressing structure or basis for intervention during the temporary storage process. This makes it easy for the falling paper to misalign, warp, or even fall out of the stacking space due to uncontrollable factors such as wind resistance and material elasticity, resulting in stacking failure. Consequently, the final misaligned paper is not neatly stacked.

[0029] In summary, existing staggered paper delivery devices generally cannot effectively stack and collect the printing media output by the printer at high efficiency, thus creating a technical constraint on the development of printers with higher transmission efficiency. Furthermore, the stacking and collection neatness of existing staggered paper delivery devices is poor. Therefore, existing staggered paper delivery devices need improvement. Utility Model Content

[0030] The technical objective of this utility model is to address the unique characteristics of high-speed printers in collecting printed output paper through staggered stacking, as well as the shortcomings of existing technologies, by providing a material collection device for collecting single-sheet printed media that can reliably achieve staggered stacking and collection of printing media output by printers with high efficiency, good stacking neatness, and stable stacking, and a high-speed printer including the material collection device.

[0031] The technical objective of this utility model is achieved through the following technical solution: a material collection device for stacking and collecting single-sheet printing media, including a material collection frame and stop components and a material collection platform arranged on the material collection frame;

[0032] The receiving frame is arranged at the printer's output port;

[0033] The stop assembly is arranged above the receiving platform and is used to stop and constrain each sheet of printing media that enters the receiving platform sequentially from the travel head.

[0034] The receiving platform is mounted on the receiving frame with a liftable structure, and works with the stop assembly to stack and collect the sequentially entering printing media.

[0035] Upstream of the receiving platform, there is an output path offset mechanism that sequentially connects the printing media conveying path of the printer. The output path offset mechanism has at least an inclined conveying mechanism. The inclined conveying mechanism has guide side blocks arranged along the printing media conveying direction, and the drive roller of the inclined conveying mechanism is engaged with the guide side blocks at an acute angle in the conveying direction. The printing media entering the inclined conveying mechanism moves forward along the guide side blocks.

[0036] The discharge path offset mechanism can translate the printing medium conveying path laterally along the printing medium conveying direction to change the trajectory of the printing medium entering the receiving platform in the lateral direction of the printing medium conveying direction.

[0037] The discharge path offset mechanism shifts the printed media laterally, causing the printed media that enter the receiving platform sequentially to be stacked in a laterally staggered manner according to a set configuration.

[0038] Furthermore, the discharge path offset mechanism is arranged on the receiving frame and is located upstream of the receiving platform.

[0039] The aforementioned technical measures address the unique characteristic of high-speed printers in collecting printed output media (including but not limited to paper, and possibly single flat sheets of film; in short, any single flat printable medium is applicable) using a staggered stacking method. A liftable receiving platform, in conjunction with an upper stop assembly, aligns and stacks the printed media sequentially entering the receiving platform in the conveying direction. Furthermore, a specially structured discharge path offset mechanism is arranged upstream of the receiving platform. This mechanism can translate laterally along the printing media conveying direction. This lateral translation of the discharge path offset mechanism correspondingly shifts the continuously conveying printed media in the conveying direction, altering the conveying trajectory of the continuously conveying printed media into the receiving platform. This naturally results in a staggered lateral stacking of the printed media sequentially entering the receiving platform according to a pre-defined stacking unit (i.e., the aforementioned paper stacking unit, hereinafter the same). Specifically, when stacking the same set of stacking units, the lateral translation of the discharge path offset mechanism keeps the guide sidebar in a specific position. Under this state, the printing media guided by the sidebar enter the receiving platform sequentially in the conveying direction, forming an aligned stack in the lateral direction. When stacking another set of stacking units, the lateral translation of the discharge path offset mechanism changes the position of the guide sidebar. Under this state, the printing media guided by the sidebar enter the receiving platform sequentially in the conveying direction, forming a corresponding aligned stack in the lateral direction. In this way, by changing the position of the guide sidebar correspondingly through the lateral translation of the discharge path offset mechanism, the printing media output by this guide forms a laterally staggered stacking collection in the height direction.

[0040] Therefore, the aforementioned technical measures achieve lateral staggered stacking of printing media entering the receiving platform according to a set stacking unit. This is achieved by using a single lateral translation of the discharge path offset mechanism with a specific structure to change the continuous transport trajectory of the printing media. During the continuous stacking process within the same stacking unit, there are no redundant stacking actions performed on the printing media entering the receiving platform, thus not affecting the continuous reception of subsequent materials. This reliably and significantly improves the printer's transmission efficiency of printing media. When switching to different stacking units, the discharge path offset mechanism only needs a single stroke (existing technologies require processes such as lifting the paper-tapping assembly, translating the receiving platform, and lowering the paper-tapping assembly) to achieve lateral staggered stacking of the printing media, greatly reducing the action time. Therefore, the aforementioned technical measures, while achieving the effect of lateral staggered stacking of printing media, can reliably receive the printing media output by the printer at high efficiency, which is beneficial to improving the overall paper transmission efficiency of the applied printer and provides effective technical support for the development of printers with higher transmission efficiency. Meanwhile, the aforementioned technical measures achieve lateral staggered stacking by using different conveying trajectories of the printing media entering the receiving platform. There is no unnecessary frictional contact force during stacking and collection, thus ensuring high-quality alignment of the printing media constituting the stacking units during natural stacking. The stacking units in the lateral staggered stacking are neatly stacked in the height direction, reliably guaranteeing the final neatness of the staggered stacking, resulting in good stacking uniformity. Furthermore, since the lateral staggered stacking of the printing media on the receiving platform is achieved by changing its own trajectory, the receiving platform itself only performs a descent to adapt to changes in stacking height. There is no other structure generating pressure on the sides of the printing media stacking structure. This ensures that the printing media forms a stable stack on the receiving platform, thus facilitating the collection of stacks with greater height (larger batches).

[0041] In the aforementioned technical measures, the discharge path offset mechanism can be arranged either on the receiving frame and upstream of the receiving platform, or on the main frame of the printer body and upstream of the receiving platform. When the discharge path offset mechanism is arranged on the receiving frame, the "corresponding frame" mentioned above is the receiving frame; when the discharge path offset mechanism is arranged on the main frame of the printer body, the "corresponding frame" mentioned above is the main frame of the printer body.

[0042] As one of the preferred technical solutions, the inclined conveying mechanism of the discharge path offset mechanism is an inclined roller conveying mechanism;

[0043] The inclined roller conveying mechanism has multiple rotatable drive inclined rollers that are sequentially assembled on the corresponding frame along the printing media conveying direction, a guide side block arranged at one end of these drive inclined rollers along the printing media conveying direction to guide the conveyed printing media, a sliding drive assembly that drives the guide side block to move laterally along the printing media conveying direction on the corresponding frame, and a rotation drive assembly that drives these drive inclined rollers to rotate along a set conveying direction.

[0044] Each drive roller is engaged with the guide side at an acute angle in the printing media conveying direction. The drive rollers, which rotate along the set conveying direction, drive the incoming printing media to move towards the guide side and convey it to the receiving platform with the guide side as the alignment reference.

[0045] The guide side is mounted on the corresponding frame in a translatable structure via the sliding drive assembly.

[0046] The aforementioned technical measures utilize a slanted roller conveyor mechanism with an adjustable conveying trajectory to form a discharge path offset mechanism. Based on the edge-conveying characteristics of the slanted roller conveyor, guide side barriers guide the printing media conveyed along the edge during transport, thus guiding the trajectory of the continuously transported printing media. This ensures that printing media forming the same stacking unit on the receiving platform enter the platform along the same trajectory, naturally resulting in highly uniform stacking. Based on this, by altering the trajectory of the continuously transported printing media through guide side barriers, stacking units from different batches during continuous transport form highly uniform, laterally staggered stacks along the height of the receiving platform.

[0047] Furthermore, the inclined roller conveying mechanism has a bridge plate arranged around the outer periphery of the drive inclined roller, which works in conjunction with the drive inclined roller to carry the conveyed printing medium;

[0048] The bottom of the guide side block has a bent transition bottom edge, which overlaps and fits into the bottom edge of the side of the bridge plate that is fitted with the guide side block;

[0049] When the guide side block moves laterally in the direction of printing media transport, the bottom edge of the side block transitions and the corresponding edge of the bridge plate are fitted together in a nested relationship.

[0050] The above technical measures are based on the characteristics of the inclined roller conveyor mechanism for side conveying and the structural special characteristics of the guide side block for lateral translation with reference to the drive inclined roller. While not interfering with the rotational movement of the drive inclined roller, they can effectively prevent the printing medium conveyed side from getting stuck in the joint gap of the guide side block's lateral translation, thus reliably meeting the technical requirements of the guide side block's lateral translation changing the trajectory of the printing medium.

[0051] Furthermore, at least one set of linear sliding components corresponding to the translational direction of the guide side is also provided between the guide side and the corresponding frame;

[0052] Driven by the sliding drive assembly, the guide side block moves in translation along the linear sliding assembly on the corresponding frame.

[0053] The above-mentioned technical measures can ensure that the guide side of the lateral translation can move smoothly and accurately on the corresponding frame (such as the receiving frame) with the transmission inclined roller as a reference.

[0054] As an alternative technical solution, the inclined conveying mechanism of the discharge path offset mechanism is an inclined roller conveying mechanism;

[0055] The inclined roller conveying mechanism has an inclined roller support mounted on the corresponding frame with a lateral translation structure, multiple rotatable transmission inclined rollers sequentially mounted on the inclined roller support along the printing media conveying direction, guide side blocks arranged at one end of these transmission inclined rollers along the printing media conveying direction to guide the conveyed printing media, a sliding drive assembly that drives the inclined roller support to lateral translation along the printing media conveying direction on the corresponding frame, and a rotation drive assembly that drives these transmission inclined rollers to rotate along a set conveying direction.

[0056] Each drive roller is engaged with the guide side at an acute angle in the printing media conveying direction. The drive rollers, which rotate along the set conveying direction, drive the incoming printing media to move towards the guide side and convey it to the receiving platform with the guide side as the alignment reference.

[0057] The guide side stop is fixedly mounted on the inclined roller support.

[0058] The aforementioned technical measures utilize a slanted roller conveyor mechanism with an adjustable conveying trajectory to form a discharge path offset mechanism. Based on the edge-conveying characteristics of the slanted roller conveyor, guide side barriers guide the printing media conveyed along the edge during transport, thus guiding the trajectory of the continuously transported printing media. This ensures that printing media forming the same stacking unit on the receiving platform enter the platform along the same trajectory, naturally resulting in highly uniform stacking. Based on this, by altering the trajectory of the continuously transported printing media through guide side barriers, stacking units from different batches during continuous transport form highly uniform, laterally staggered stacks along the height of the receiving platform.

[0059] As one of the preferred technical solutions, the receiving device also includes an automatic translation control system for controlling the lateral translational movement of the corresponding structure of the discharge path offset mechanism. The automatic translation control system mainly consists of a counting sensor, a sliding stroke sensor, a motor constituting the sliding drive assembly, and a controller.

[0060] The counting sensor is used to detect the number of printing media that enter the receiving platform sequentially, and to feed back a detection signal to the controller according to a set counting cycle.

[0061] The sliding stroke sensor is used to detect the lateral translational stroke position of the corresponding structure of the discharge path offset mechanism driven by the sliding drive assembly, and to feed back the detection signal to the controller.

[0062] The motor constituting the sliding drive assembly, under the control command of the controller, is used to drive the sliding drive assembly to move in a set direction and stroke, so as to drive the corresponding structure of the discharge path offset mechanism to move laterally and reciprocate.

[0063] The above technical measures are designed to meet the automated control of horizontal staggered stacking. They enable the printing media continuously output by the printer to automatically form stacking units according to the designed number of sheets, thereby forming horizontal staggered stacking with high automation and precision.

[0064] Furthermore, the counting sensors are arranged at the output end of the discharge path offset mechanism;

[0065] The printing medium output by the discharge path offset mechanism passes through the detection range of the counting sensor during its entry into the receiving platform.

[0066] Using a counting sensor with the aforementioned technical measures to trigger the controller's command output action, the system is easy to implement and has low technical difficulty while meeting high accuracy requirements.

[0067] As one of the preferred technical solutions, the discharge path offset mechanism also has a wind-powered mechanism;

[0068] The wind power mechanism can generate wind on the conveying working surface of the inclined conveying mechanism, and the direct area of ​​the wind power generated by the wind power mechanism on the conveying working surface of the inclined conveying mechanism is close to the guide side.

[0069] When the printing medium is conveyed to the inclined conveyor, the wind force generated by the wind mechanism acts on the currently conveyed printing medium, forcing the currently conveyed printing medium to move forward on the inclined conveyor with the guide side as the alignment reference and be conveyed to the receiving platform.

[0070] The aforementioned technical measures utilize a wind-powered mechanism arranged at a specific location in conjunction with an inclined conveyor to form a discharge path offset mechanism. This increases the lateral component of the contact friction force between the printing medium entering the inclined conveyor and the guide side. This forces the printing medium, during continuous transport, to accelerate and move towards the edge, using the guide side as an alignment reference. This improves the accuracy of the edge alignment of the printed medium output by the inclined conveyor, thereby enhancing the neatness of the printed medium stacked on the receiving platform. Simultaneously, using a wind-powered mechanism to force the printing medium to move towards the edge of the inclined conveyor does not interfere with the mechanical movement of the transported printing medium or cause time consumption. In other words, this accelerated edge-movement method does not affect the high-efficiency transport of the printing medium, meeting the technical requirements for high-efficiency printing medium transport.

[0071] Furthermore, the wind force generated by the wind mechanism directly acts on the conveying working surface of the inclined conveying mechanism within 2 / 3 of the width of the currently conveyed printing medium, with the guide side as the conveying reference.

[0072] Furthermore, the printing medium is any one of the following single-sheet, flat printing media specifications: A3, A4, B3, B4, 8K, and 16K.

[0073] The wind force generated by the wind power mechanism directly affects the conveying working surface of the inclined conveying mechanism within a range of 200mm in width from the guide side as the conveying reference, and is located in the conveying direction.

[0074] Furthermore, the printing medium is printing paper;

[0075] The wind force generated by the wind power mechanism directly acts on the printing medium being transported, and the wind pressure is within the range of 2 to 50 Pa.

[0076] The aforementioned technical measures enable the wind-powered mechanism to reliably cooperate with the inclined conveyor mechanism, ensuring that the dynamically conveyed printing media is reliably accelerated to the edge, thus guaranteeing that the printing media is aligned with the guide edge on the inclined conveyor mechanism. Simultaneously, these technical measures prevent excessive wind force from causing impact, floating, displacement, denting, bending, or deformation of the printing media on the inclined conveyor mechanism, ensuring smooth conveying while achieving accelerated edge alignment.

[0077] Furthermore, the air vents of the wind power mechanism are arranged above the conveying working surface of the inclined conveying mechanism. The wind force through the air vents acts on the conveying working surface of the inclined conveying mechanism in a blowing manner, and the wind force through the air vents directly conveys the path, with the guide side as a reference, and is in a right-angle or obtuse-angle relationship with the plane of action of the currently conveyed printing medium.

[0078] Alternatively, the inclined conveying mechanism is an inclined roller conveying mechanism, and the air inlets of the wind power mechanism are arranged below the conveying working surface of the inclined roller conveying mechanism. The wind force through the air inlets acts on the conveying working surface of the inclined roller conveying mechanism in a suction manner, and the wind force through the air inlets directly conveys the path, with the guide side as the reference, and the plane of action of the currently conveyed printing medium is in a right angle or acute angle relationship with it.

[0079] In the aforementioned technical measures, if the direct delivery path of the airflow from the wind turbine is substantially parallel to the guide side, the contact friction between the printing medium and the inclined conveying mechanism is increased, ensuring that the printing medium moves closer to the edge more quickly during transport. If the direct delivery path of the airflow from the wind turbine forms an obtuse angle (for cases where the air outlet is above) / an acute angle (for cases where the air outlet is below) with the plane of the printing medium on the side facing the guide side, this not only increases the contact friction between the printing medium and the inclined conveying mechanism but also applies a certain pushing / suction force towards the guide side to the printing medium. This, combined with the dynamic transport process of the printing medium by the inclined conveying mechanism, results in more efficient and faster movement to the edge.

[0080] Furthermore, the wind power mechanism has a fan bracket and multiple small electric fans arranged on the fan bracket;

[0081] The fan bracket is fixed on the corresponding frame where the inclined conveying mechanism is located;

[0082] Each small electric fan is arranged sequentially on the fan bracket in the direction of printing media delivery.

[0083] The wind power mechanism composed of the above-mentioned technical measures has the following technical characteristics: firstly, it has the advantages of simple structure, easy molding, low manufacturing cost and low maintenance cost, and convenient maintenance; secondly, it can effectively match the conveying range of the inclined roller conveyor mechanism, so that the printing medium can accelerate to the edge with the guide side as the alignment reference during the continuous conveying process of the inclined roller conveyor mechanism.

[0084] As one of the preferred technical solutions, a pressing transmission mechanism that drives in the direction of printing medium conveying is arranged above the receiving platform and / or the discharge path offset mechanism.

[0085] The material pressing transmission mechanism has a front shaft that first engages with the printing medium being conveyed, a rear shaft that then engages with the printing medium being conveyed, and multiple media guide belts that are fitted between the front shaft and the rear shaft and circulate in a continuous transmission. These media guide belts are arranged at intervals along the axial direction of the front shaft and the rear shaft.

[0086] During the cyclic transmission process, the media guide belt, together with the lower receiving platform and / or the discharge path offset mechanism, forms a channel that allows the currently conveyed printing media to enter and prevents drift.

[0087] The material pressing and transmission mechanism of the above-mentioned technical measures, together with the receiving platform and / or the discharge path offset mechanism below, forms a conveying channel for the printing medium, thereby ensuring that the printing medium below is stable to prevent drift and improving the final stacking neatness.

[0088] As one of the preferred technical solutions, the stop assembly has a material-blocking crossbeam mounted on the receiving frame and located above the receiving platform. The material-blocking crossbeam is arranged on the receiving frame in a structure transverse to the printing media conveying direction.

[0089] The bottom of the baffle beam is arranged with multiple downward-protruding baffle protrusions. The downward protrusion height of these baffle protrusions, at least in the horizontal direction, can cover the discharge port of the discharge path offset mechanism. The surfaces of these baffle protrusions that meet the printing medium are coplanar, and the arrangement distance between adjacent baffle protrusions is less than the width dimension of the printing medium in the conveying direction. The printing medium entering the receiving platform covers at least two baffle protrusions in the width direction of the conveying direction.

[0090] When the receiving platform rises to its highest position on the receiving frame, the bearing plane of the receiving platform and the lowest end of the material blocking protrusion form an alternating upper and lower position. The surface of the material blocking protrusion that receives the printing media forms a space on and above the bearing plane of the receiving platform for stacking the sequentially entering printing media.

[0091] The above-mentioned technical measures use multiple baffle protrusions at the bottom of the crossbeam to make multi-point contact stops on the printing media entering the receiving platform in the lateral direction. This ensures that the printing media entering the receiving platform is stably stressed at the traveling head, preventing the printing media from being tilted or displaced by impact in the traveling direction, which helps to improve the final stacking neatness.

[0092] Furthermore, the guide beam corresponds to the printing media conveying direction and is mounted on the receiving frame in a sliding structure;

[0093] Correspondingly, the receiving platform has multiple clearance grooves on its bearing surface that run along the direction of printing media transport and match the material blocking protrusions on the material blocking beam.

[0094] The aforementioned technical measures create clearance grooves on the receiving platform that allow the material-blocking protrusions on the crossbeam to pass through, as well as a sliding structure that works in conjunction with the crossbeam. This allows the stop assembly to work with the receiving platform to create receiving spaces adaptable to different specifications, offering good flexibility. Furthermore, the clearance groove structure on the receiving platform does not hinder its ability to support the stacking of printing media, ensuring stable stacking of the media. Simultaneously, the clearance groove structure on the receiving platform facilitates reliable forklift unloading after stacking, resulting in highly convenient unloading operations.

[0095] Furthermore, the material-stopping beam is mounted on the receiving frame in a slidable structure via a slider;

[0096] The slider is connected to a pressure roller located in front of the material blocking beam to prevent the printing media from drifting when entering the receiving platform.

[0097] The above-mentioned technical measures address the slippage of the crossbeam by incorporating a pressure roller that moves with the crossbeam in its sliding structure. This ensures that the pressure roller can prevent the printing media from drifting and press down on the stack below, regardless of how the crossbeam slides. In particular, the pressure roller works in conjunction with the pressure transmission mechanism to press down the media without affecting the feeding process. This not only improves the stability of the printing media stack on the receiving platform but also enhances the neatness of the stack.

[0098] Furthermore, the receiving platform extends from the receiving frame in accordance with the direction of printing media transport;

[0099] Correspondingly, the stop assembly also has a material stop bracket for mounting the material stop beam. The material stop bracket is fixed on the receiving frame and located above the receiving platform. The material stop bracket is at least a cantilever structure extending along the printing media conveying direction.

[0100] The material-stopping beam is mounted on the cantilever of the material-stopping bracket in a sliding structure.

[0101] The aforementioned technical measures extend the receiving platform into a receiving frame, which, without hindering stable stacking and receiving, opens up the operating space on the receiving platform, facilitating unloading operations.

[0102] As one of the preferred technical solutions, the receiving device also includes an automatic lifting control system for controlling the lifting movement of the receiving platform. The automatic lifting control system mainly consists of a receiving detection sensor, a lifting stroke sensor, a motor constituting the lifting drive assembly, and a controller.

[0103] The receiving detection sensor is arranged above the receiving platform, forming an input channel for sequentially conveying printing media between the receiving platform's bearing plane and the uppermost layer of printing media during continuous stacking. The receiving detection sensor is used to detect the stacking height of the printing media continuously stacked on the receiving platform and to feed back a detection signal to the controller.

[0104] The lifting stroke sensor is used to detect the vertical lifting stroke position of the receiving platform driven by the lifting drive assembly and to feed back the detection signal to the controller.

[0105] The motor constituting the lifting drive assembly is used to drive the lifting drive assembly to move according to the set motion direction and stroke under the control command of the controller, so as to drive the receiving platform to perform vertical lifting and reciprocating motion on the receiving frame.

[0106] The above-mentioned technical measures are designed to meet the automated control of printing media stacking and collection. They enable the receiving platform to descend smoothly according to the dynamic changes in the continuous stacking height of the printing media, so as to ensure the smoothness of feeding and the neatness and stability of stacking. The system is highly automated and accurate.

[0107] A high-speed printer has a printer body, wherein the printer body has a sequential transport path for a single sheet of printing media from supply to receipt.

[0108] At the discharge port of the sequential conveying path of the printer body, a receiving device of any of the above structures is arranged to collect and stack the printing media output by the printer body according to a set stacking method.

[0109] The high-speed printer with the above-mentioned technical measures has a receiving device with the above-mentioned structure arranged at the discharge port, and therefore has the technical advantages of the above-mentioned receiving device.

[0110] The beneficial technical effects of this utility model are as follows: Addressing the unique characteristic of high-speed printers in collecting printed media through staggered stacking, the above-mentioned technical measures, based on a liftable receiving platform and an upper stop assembly, include a specially structured discharge path offset mechanism arranged upstream of the receiving platform. This mechanism can laterally shift along the conveying direction of the printed media. Through this lateral shift, the continuously conveying printed media are correspondingly laterally shifted in the conveying direction, altering the conveying trajectory of the continuously conveying printed media entering the receiving platform. This naturally results in the sequentially entering printed media forming a laterally staggered stack according to a set stacking unit. Since the above technical measures eliminate redundant stacking actions for the printed media entering the receiving platform, while achieving the laterally staggered stacking effect, it reliably receives the high-efficiency printed media output by the printer, improving the overall paper transport efficiency of the applied printer and providing effective technical support for developing printers with higher transport efficiency.

[0111] Meanwhile, the above-mentioned technical measures can ensure that the printing media constituting the stacking unit forms a high-quality alignment in natural stacking, and that each group of stacking units stacked laterally in a staggered manner is neatly stacked in the height direction, thereby reliably ensuring the neatness of the final staggered stacking; it can also ensure that the printing media forms a stable stack on the receiving platform, which is conducive to achieving stacking collection of larger heights (larger batches).

[0142] This utility model relates to the field of printer technology, specifically a material collection device for stacking and collecting single-sheet printing media, and a high-speed printer including the material collection device. The main technical solution of this utility model will be described in detail below with reference to several embodiments. Embodiment 1 is illustrated in conjunction with the accompanying drawings—that is… Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 The technical solution of this utility model is clearly and thoroughly explained.

[0144] 1. The accompanying drawings of this utility model are schematic, and unnecessary details have been simplified in order to clarify the technical purpose of this utility model, so as to avoid obscuring the technical solution contributed by this utility model to the prior art.

[0145] 2. The printing medium of this utility model is usually a single sheet of flat paper, but it does not exclude single sheet of flat film or other printable media, that is, any single sheet of flat printable media is applicable; as for folded paper, thick plate media, etc., they are not applicable to this utility model, that is, the printing medium of this utility model does not include these.

[0146] 3. The terms "approximately" and "basically" used in the following text regarding quantity or fit relationships mean that reasonable assembly and processing errors are allowed within the industry, and do not literally describe absolute quantities or fit relationships.

[0147] Example 1

[0148] The high-speed printer of this utility model, such as Figure 17 and Figure 18 As shown, this high-speed printer is a commercial or industrial high-speed continuous printer (i.e., a sheet-fed inkjet printer, designed only for stacked printing media, not roll-fed printing media), and it has a printer body 9. The printer body 9 has a main frame 91 and a feeding mechanism 92 (paper feeding mechanism) and a receiving mechanism (paper receiving mechanism) arranged on the main frame 91 - that is, the receiving device of this utility model.

[0149] The printer body 9 is based on the length direction of the main frame 91, with the feeding mechanism 92 and the receiving device of this invention arranged at the left and right ends of the main frame 91 respectively. The feeding mechanism 92 and the receiving device of this invention form a sequential conveying path on the main frame 91 for single sheets of printing media in the stacked printing media from supply to collection.

[0150] The feeding mechanism 92 is arranged at the feed inlet of the sequential conveying path of the main frame 91. The feeding mechanism 92 is used to place and convey stacked printing media (e.g., stacked paper) one sheet at a time. In this embodiment, to achieve continuous delivery of a large amount of printing media and reduce interruptions and downtime due to lack of printing media during printing, two sets of feeding mechanisms 92 are redundantly configured. These two sets of feeding mechanisms share the same feeding bracket and are arranged in a high-low layer on the common feeding bracket.

[0151] Specifically, the first feeding mechanism is located below the second feeding mechanism, and it is sequentially connected to the upstream end of the sequential conveying path through the feeding conveying section.

[0152] At the feed inlet of feeding mechanism two, a feed bypass conveying mechanism is arranged to sequentially connect the feed inlet of feeding mechanism two with the feed conveying section. That is, the feed inlet of feeding mechanism two is connected to the junction of the feed inlet of feeding mechanism one and the feed conveying section via the feed bypass conveying mechanism, so that the printing medium conveyed by feeding mechanism two enters the first horizontal conveying section, which constitutes the sequential conveying path, via the feed bypass conveying mechanism and the feed conveying section. The feed bypass conveying mechanism is basically arranged vertically on the feeding support.

[0153] Based on the aforementioned redundant configuration of feeding mechanisms one and two, simultaneous feeding is not possible during printing; each mechanism can only feed material individually. Therefore, the feed rollers at the feed inlets of feeding mechanisms one and two only rotate during the current feeding period; otherwise, they remain stationary. Their rotation is controlled by the printer's control system, which uses pre-set commands to switch feeding between feeding mechanisms one and two. Thus, assuming feeding mechanism one feeds first and feeding mechanism two as a backup, when the stacked printing media on feeding mechanism one is depleted, the control system switches to feeding mechanism two to continue feeding. This allows the operator to freely place stacked printing media on feeding mechanism one without interfering with the printer's continuous operation, enabling feeding mechanism one to function as a backup. The same applies when feeding mechanism two is depleted.

[0154] The material receiving device of this utility model is arranged at the outlet of the sequential conveying path of the main frame 91, and is used to receive the printing media output by the sequential conveying path, and to stack and collect each printed medium according to the set requirements.

[0155] The feeding mechanism 92 and the receiving device of this invention form a sequential conveying path on the main frame 91 for single sheets of printing media from supply to collection. This path, along the height of the main frame 91, comprises a first horizontal conveying section, a first vertical conveying section, a second horizontal conveying section, a second vertical conveying section, and a third horizontal conveying section connected in sequence. The third horizontal conveying section is positioned above the second horizontal conveying section. As a transitional conveying section between the sequential conveying path and the receiving device of this invention, its horizontal position is not critical; basic horizontal conveying is sufficient. The tail end of the third horizontal conveying section is sequentially connected to the receiving device of this invention.

[0156] The second horizontal conveyor section is positioned above the first horizontal conveyor section. As described below, the second horizontal conveyor section requires the arrangement of the printing mechanism and the correction mechanism, thus the second horizontal conveyor section is basically arranged horizontally on the main frame 91.

[0157] The first end of the first horizontal conveyor section is sequentially connected to the feeding mechanism. As described below, the first horizontal conveyor section needs to accommodate the printing mechanism and the correction mechanism, so the first horizontal conveyor section is basically arranged horizontally on the main frame 91.

[0158] Thus, a sequential conveying path with an S-shaped loop structure from bottom to top is formed between the feeding mechanism 92 on the main frame 91 and the receiving device of this utility model. This not only meets the technical requirements for setting up a sequential conveying path for double-sided printing, but also effectively reduces the length of the main frame 91 and thus reduces the floor space.

[0159] Based on the structural characteristics of the feeding mechanism 92 and the sequential conveying path characteristics of the S-shaped loop structure from bottom to top on the main frame 91, in order to facilitate the arrangement of the feeding mechanism 1 on the main frame 91 and to smoothly connect with the beginning of the first flat conveying section, the feeding conveying section arranged at the feeding port of the feeding mechanism 1 is arranged on the feeding support with an inclined structure.

[0160] Because the high-speed printer of this invention is relatively large compared to a general office printer, in order to facilitate the transportation of the entire machine and reduce the high requirements for transportation space, the feeding bracket of the feeding mechanism 92 is assembled in a detachable combination structure at the corresponding end of the main frame 91. Similarly, the receiving frame of the receiving device of this invention is assembled in a detachable combination structure at the corresponding end of the main frame 91.

[0161] To accommodate double-sided printing of the conveyed printing media, a first printing mechanism is arranged on the first flat conveyor section, and a second printing mechanism is arranged on the second flat conveyor section; both the first and second printing mechanisms employ inkjet printing structures. The printing operation process is as follows, executed according to the printing task settings within the control system:

[0162] When only one side of the current printing medium needs to be printed, the printing medium conveyed by the feeding mechanism 92 will be transported in an S-shaped path along the first horizontal conveying section, the first vertical conveying section, the second horizontal conveying section, the second vertical conveying section, and the third horizontal conveying section. During the conveying process, according to the set instructions, the corresponding printing mechanism on the first horizontal conveying section / second horizontal conveying section will print graphic information on the upper surface of the printing medium. The other printing mechanism will not work, and its conveying section will only be used for conveying the current printing medium.

[0163] When double-sided printing is required on the current printing medium, the printing medium conveyed by the feeding mechanism 92 is printed on the upward-facing surface by the first printing mechanism on the first horizontal conveying section. After being conveyed by the first vertical conveying section, the printing medium with the first side printed is formed with the second side facing up and the first side facing down on the second horizontal conveying section. After the second side is printed by the second printing mechanism, double-sided printing is completed. Then, it is conveyed to the receiving device of this utility model by the second vertical conveying section and the third horizontal conveying section.

[0164] To ensure high-quality printing by ensuring consistent positioning of sequentially transported printing media by the first and second printing mechanisms, a first correction mechanism is provided upstream of the first printing mechanism to correct the deviation of individual printing media, corresponding to the set transport direction of the printing media on the sequential transport path. That is, the first correction mechanism and the first printing mechanism are located on the first flat transport section. Similarly, a second correction mechanism is provided upstream of the second printing mechanism to correct the deviation of individual printing media, that is, the second correction mechanism and the second printing mechanism are located on the second flat transport section.

[0165] The first and second correction mechanisms described above have the same structure. In this embodiment, the correction mechanism includes a cooperating inclined conveying mechanism and a wind-powered mechanism. Specifically, the inclined conveying mechanism is an inclined roller drive structure with multiple rotatable drive rollers sequentially mounted on the main frame 91 along the printing media conveying direction. These drive rollers are rotatably mounted on the same plane on the main frame 91, and adjacent drive rollers maintain essentially the same fit clearance and tilt angle. The inclined conveying mechanism also has a guide side that protrudes on one side of the inclined conveying mechanism along the printing media conveying direction. This guide side is fixedly connected to the main frame 91 and is stationary relative to the drive rollers. The guide side aligns with the positioning reference of the downstream printing mechanism that it cooperates with. Each drive roller engages with the guide side at an acute angle in the printing media conveying direction. The wind-powered mechanism has a fan bracket and multiple sets of electric fans arranged on the fan bracket. The fan bracket is supported and fixed on the main frame 91 and is located above the inclined conveying mechanism. Each set of electric fans is arranged on the fan bracket along the direction of printing media transport, and the arrangement of these electric fans basically corresponds to the longitudinal length of the transport working surface of the inclined conveyor mechanism. The air outlet of the fan mechanism faces the transport working surface of the inclined conveyor mechanism, and the direct transport path of the air force blown by the fan mechanism, with the guide side as the reference, is perpendicular to the plane of action of the inclined conveyor mechanism. That is to say, the direct transport path of the air force blown by the fan mechanism is basically parallel to the guide surface of the guide side. In the cooperation between the fan mechanism and the inclined conveyor mechanism, the air force blown by the fan mechanism cannot cover the lateral width of the currently transported printing media in the transverse direction (with the printing media transport direction as the longitudinal direction). It can only have an effect on the area of ​​the currently transported printing media close to the guide side. That is, the direct area of ​​action of the air force blown by the fan mechanism in the transport working surface of the inclined conveyor mechanism should be close to the guide side. Only in this way can it cooperate with the inclined conveyor mechanism to dynamically turn and correct the printing media during transport. Typically, the air pressure exerted by each electric fan of the wind power mechanism on the printed medium being transported should be controlled within the range of 2 to 50 Pa, preferably within the range of 5 to 10 Pa.

[0166] As described above, a sequential conveying path is formed on the main frame 91 between the feeding mechanism 92 and the receiving device of this utility model. This path consists of a feeding conveying section, a first horizontal conveying section, a first vertical conveying section, a second horizontal conveying section, a second vertical conveying section, and a third horizontal conveying section, connected in sequence from bottom to top. This path is used to convey the printing media output by the feeding mechanism 92. Therefore, each conveying section must be equipped with a conveying mechanism that conveys the printing media in a set direction. These conveying mechanisms do not have specific structural requirements and can use commonly used paper conveying mechanisms, as long as they meet the requirements for conveying the printing media (such as paper).

[0167] As described above, the material receiving device of this utility model is arranged at the material outlet of the sequential conveying path of the main frame 91 of the printer body 9, and is used to receive the printing media output by the sequential conveying path, and to stack and collect each received printing media according to the set requirements.

[0168] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, the material receiving device of this utility model includes a material receiving frame 1 and a stop assembly 2, a material receiving platform 3, a material receiving detection sensor 4, a first pressing transmission mechanism 5, a discharge path offset mechanism 6, a counting sensor 7, a second pressing transmission mechanism 8, and a corresponding automatic control system arranged on the material receiving frame 1.

[0169] Specifically, the receiving frame 1 is detachably assembled at the discharge port of the main frame 91 of the printer body 9, and is used to receive the printing media output from the sequential conveying path within the main frame 91.

[0170] like Figure 15 and Figure 16 As shown, the receiving platform 3 serves as a carrier for receiving printing media and stacking the received printing media. To ensure that the printing media enters the receiving platform 3 smoothly and to accommodate the batch collection and stacking of printing media continuously output by the printer body 9, the receiving platform 3 is mounted on the receiving frame 1 with a liftable structure.

[0171] More specifically, the receiving platform 3 is mounted on the receiving frame 1 in a vertical linear sliding structure, and the receiving platform 3 is connected to a lifting drive assembly that controls the linear sliding motion. This lifting drive assembly is a screw drive structure, mainly composed of a transmission screw, a drive motor, and a nut; the lifting drive assembly also has an automatic receiving control system, which controls the lifting motion of the receiving platform 3 by driving the screw drive pair.

[0172] The transmission screw of the lifting drive assembly is vertically mounted on the receiving frame 1 in a rotatable structure, and the bottom end of the transmission screw is connected to the drive motor. The nut of the lifting drive assembly is fixedly connected to the receiving platform 3 and threadedly connected to the transmission screw. During the rotation of the transmission screw, the nut is driven, and the receiving platform 3 is linearly displaced and lifted on the receiving frame 1 by the linear sliding assembly of the receiving platform 3 on the receiving frame 1.

[0173] The automatic receiving control system mainly consists of a receiving detection sensor 4, a lifting stroke sensor, a drive motor constituting the lifting drive assembly, and a controller. The receiving detection sensor 4 is positioned above the receiving platform 3, forming an input channel for sequentially conveying printing media between itself, the bearing plane 31 of the receiving platform 3, and the uppermost layer of printing media during continuous stacking. The receiving detection sensor 4 detects the stacking height of the printing media continuously stacked on the receiving platform 3 and sends a detection signal back to the controller. The lifting stroke sensor detects the vertical lifting stroke position of the receiving platform 3 driven by the lifting drive assembly and sends a detection signal back to the controller. The drive motor constituting the lifting drive assembly, under the control command of the controller, drives the lifting drive assembly to move according to the set motion direction and stroke, thereby driving the receiving platform 3 to perform vertical lifting and reciprocating motion on the receiving frame 1.

[0174] To improve the ease of unloading printing media stacked on the receiving platform 3, the receiving platform 3 extends into a receiving frame 1 corresponding to the printing media conveying direction, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 15 , Figure 17 and Figure 18 As shown. That is to say, the part of the receiving platform 3 close to the printer body 9 is within the space restricted by the receiving frame 1, and the part of the receiving platform 3 away from the printer body 9 extends out of the space restricted by the receiving frame 1, so that the stacking collection space formed by the receiving platform 3 is relatively open, which facilitates the unloading operation of the collected stacked media.

[0175] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 13 , Figure 14 , Figure 15 , Figure 17 and Figure 18As shown, the stop assembly 2 is arranged above the receiving platform 3 to constrain each sheet of printing media entering the receiving platform 3 sequentially from the travel head (paper head, the same below). On the one hand, it prevents the printing media from slipping out due to conveying inertia after entering the receiving platform 3; on the other hand, the stop constraint ensures that each sheet of printing media forms a reference alignment in the travel direction (conveyor direction, the same below), thereby improving the neatness of stacking. The stop assembly 2 mainly consists of a material blocking bracket 21 and a material blocking crossbeam 22.

[0176] More specifically, such as Figure 3 , Figure 7 , Figure 13 and Figure 14 As shown, the stop assembly 2 has two material-blocking brackets 21, arranged laterally and spaced apart from the receiving frame 1. They are fixed to the receiving frame 1 and positioned above the receiving platform 3, forming a cantilevered arrangement on the receiving frame 1, meaning each material-blocking bracket 21 extends along the printing media conveying direction. The two ends of the stop assembly 2's material-blocking beam 22 are connected to the corresponding material-blocking brackets 21 on both sides, positioned relatively away from the printer body 9 and also above the receiving platform 3. The material-blocking beam 22 is arranged laterally to the printing media conveying direction on the receiving frame 1.

[0177] To ensure that the printing media entering the receiving platform 3 is stopped and constrained by the stop assembly 2, when the receiving platform 3 rises to its highest position on the receiving frame 1, the bearing plane 31 of the receiving platform 3 should form an interlocking fit with the material-stopping beam 22 structure of the stop assembly 2 in the upper and lower positions (e.g., Figure 4 (As shown in Figure 14), and the structure of the baffle beam 22 should be able to cover the path into the receiving platform 3 in the horizontal direction through its orthogonal projection—that is, the discharge port of the discharge path offset mechanism 6 described below, such as... Figure 4 , Figure 5 As shown. Therefore, the bottom of the baffle beam 22 is provided with multiple downwardly protruding baffle protrusions 23. The downward protrusion height of these baffle protrusions 23, at least in the horizontal direction, can cover the discharge port of the discharge path offset mechanism 6. The surfaces of these baffle protrusions 23 that meet the printing medium are coplanar, and the arrangement distance between adjacent baffle protrusions 23 is less than the width of the printing medium in the conveying direction. This ensures that the printing medium entering the receiving platform 3 can cover at least two baffle protrusions 23 in the width direction of the conveying direction. Figure 14 As shown. When the receiving platform 3 rises to its highest position on the receiving frame 1, the bearing plane 31 of the receiving platform 3 and the lowest end of the blocking protrusion 23 form an alternating upper and lower position. The surface of the blocking protrusion 23 that receives the printing media forms a space for stacking the sequentially entering printing media on and above the bearing plane 31 of the receiving platform 3.

[0178] As can be seen from the above-mentioned cooperation structure between the receiving platform 3 and the stop component 2, the receiving platform 3 cooperates with the stop component 2 to stack and collect the printing media that enter in sequence, so that the printing media entering the receiving platform 3 are positioned under the constraint of the material blocking protrusion 23 of the stop component 2, thereby aligning the printing media that enter in sequence with the material blocking protrusion 23 as the reference in the direction of travel.

[0179] To accommodate the stacking and collection of printing media of different specifications, the two ends of the stop beam 22 of the aforementioned stop assembly 2 are slidably mounted on the stop bracket 21 via corresponding sliders 24, thereby enabling displacement relative to the printer body 9 on the stop bracket 21. Figure 3 , Figure 4 , Figure 7 , Figure 13 , Figure 14 As shown. Simultaneously, based on the misaligned fit between the bottom baffle protrusion 23 of the aforementioned baffle beam 22 and the receiving platform 3, to accommodate the relative displacement of the baffle beam 22, multiple clearance grooves 32 are formed at the bearing plane 31 of the receiving platform 3, running along the printing media conveying direction and matching the passage of each baffle protrusion 23 on the baffle beam 22, as shown. Figure 1 , Figure 7 , Figure 13 , Figure 14 , Figure 16 As shown. With this matching structure, when the receiving platform 3 rises to its highest position, the material-blocking protrusion 23 at the bottom of the material-blocking beam 22 is inserted into the clearance groove 32 of the receiving platform 3, as shown. Figure 14 As shown, the through-and-through structure of the retaining protrusion 23 and the clearance groove 32 demonstrates that it does not hinder the stacking and collection of the incoming printing media by the bearing plane 31 of the receiving platform 3, as... Figure 16 As shown, the material blocking beam 22 can also slide relative to each other to adjust the collection space of different sizes.

[0180] To ensure the stability and prevent drift of the printing media entering and stacking on the receiving platform 3, rotatable pressure rollers 25 are spaced apart on the front side of the aforementioned retaining beam 22 to prevent drift of the printing media entering the receiving platform 3. These pressure rollers 25, as they rotate in the direction of printing media travel, form a channel for the printing media to enter and stack on the receiving platform 3. This is particularly effective in conjunction with the second pressure transmission mechanism 8 described below. Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 13 , Figure 14As shown. Based on this, the relative positions of the pressure roller 25 and the stop beam 22 should be such that the stop beam 22 is at the head of the currently stacked printing media in the direction of travel, and the pressure roller 25 is at the middle of the currently stacked printing media in the direction of travel. To accommodate the sliding nature of the stop beam 22, the pressure roller 25 is mounted on the slider 24 where the stop beam 22 is located.

[0181] Based on the aforementioned receiving structure, to ensure the printing media smoothly enters the receiving platform 3 and prevents curling and drifting, and to ensure the neatness of stacking, a second pressing transmission mechanism 8 is also arranged on the receiving frame 1 above the receiving platform 3, which drives along the printing media conveying direction. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 15 , Figure 17 and Figure 18 As shown. The second pressing transmission mechanism 8 has a front shaft—the third shaft 81—that first engages with the currently conveyed printing medium, and a rear shaft—the fourth shaft 82—that subsequently engages with the currently conveyed printing medium. It also includes multiple second media guide belts 83, which are circulated and driven between the third shaft 81 and the fourth shaft 82. These second media guide belts 83 are arranged at intervals along the axial direction of the third shaft 81 and the fourth shaft 82, and their positions generally correspond to the positions of the material-blocking protrusions 23 on the aforementioned material-blocking beam 22. The pressing roller 25 on the front side of the aforementioned material-blocking beam 22 is located within the circulating transmission space of the second media guide belts 83 and contacts and engages with the second media guide belts 83 located at the bottom position during circulating transmission. The aforementioned third axis 81 or fourth axis 82, acting as the drive axis of the driven component, drives the second media guide belt 83 and other associated axes to rotate in the direction of printing media transport. During the cyclic transmission process, the second media guide belt 83, together with the lower receiving platform 3 and the upper stacked media, forms a channel that allows the currently transported printing media to enter and prevents drift. Typically, to ensure the reliability of the printing media entering this transport channel, the third axis 81 of the second pressing transmission mechanism 8 is positioned slightly higher than the fourth axis 82. Of course, this height difference is relatively minor and inconspicuous.

[0182] As described above, the printing media output by the printer body 9 are neatly stacked at the travel head in the traveling direction. If the printing media output by the printer body 9 enters the receiving platform 3 along the same trajectory, they will also be neatly stacked in the lateral direction relative to the traveling direction, thus forming neat stacking in all four directions of the traveling direction.

[0183] To classify and stack the printing media during large-volume continuous printing—that is, to classify and stack them according to a set number of units (one unit as a stacking unit) for subsequent sorting operations—it is necessary to arrange the printing media stacked on the receiving platform 3 in a horizontally staggered manner along the height direction during continuous material receiving. Figure 16 The laterally misaligned stacking medium C is shown. Therefore, the discharge path offset mechanism 6 exists in conjunction with the aforementioned receiving platform 3 and the blocking assembly 2, as shown... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 15 , Figure 17 and Figure 18 As shown.

[0184] The discharge path offset mechanism 6 is arranged on the receiving frame 1 upstream of the receiving platform 3, serving as the sequential connection point for the printing media transport path of the printer body 9. This discharge path offset mechanism 6 can be translated laterally along the printing media transport direction to alter the trajectory of the printing media entering the receiving platform 3. Through these changes in trajectory, the printing media entering the receiving platform 3 forms a shape similar to... Figure 16 The lateral staggered stacking shown is the final stacking structure, which is the lateral staggered stacking medium C.

[0185] More specifically, the discharge path offset mechanism 6 includes an inclined roller conveyor mechanism 61 and a pneumatic mechanism 3, such as... Figure 3 and Figure 4 As shown.

[0186] like Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12As shown, the inclined roller conveying mechanism 61 has a bridge plate 611 connected to the discharge port of the printer body 9, and multiple rotatable drive inclined rollers 616 sequentially assembled in the opening area of ​​the bridge plate 611 along the printing media conveying direction. At one end of these drive inclined rollers 616, a guide side plate 612 is arranged along the printing media conveying direction to guide the conveyed printing media. These drive inclined rollers 616 are rotatably assembled on the same plane on the receiving frame 1. The adjacent drive inclined rollers 616 maintain basically the same fitting clearance and inclination angle. Each drive inclined roller 616 fits with the guide side plate 612 at an acute angle in the printing media conveying direction. The specific included angle is selected in the range of 70° to 85°, preferably 80°. This included angle should not be too large or too small, so that the printing media entering the inclined roller conveying mechanism 61 is conveyed along the guide side plate 612 under the rotation of each drive inclined roller 616, and enters the receiving platform 3 with the guide side plate 612 as the forward reference. The aforementioned bridge plate 611, together with the drive slant roller 616, constitutes the conveying working surface of the slant roller conveying mechanism 61 for conveying the printing media.

[0187] The aforementioned inclined roller conveyor mechanism 61 also has a rotary drive assembly 618 that drives the inclined rollers 616 to rotate. This rotary drive assembly 618 mainly consists of a motor, a synchronous pulley, a tensioner, and a synchronous belt. The motor, synchronous pulley, and tensioner are mounted on the receiving frame 1 below the inclined rollers 616. The output shaft of the motor is connected to the synchronous pulley. The synchronous belt is fitted between the synchronous pulley and the tensioner. The inner ring wall of the synchronous belt meshes with the synchronous pulley and the tensioner in a toothed structure. The outer ring wall of the synchronous belt frictionally engages with each inclined roller 616. During the transmission of the synchronous belt, friction drives each inclined roller 616 to rotate. Figure 4 As shown.

[0188] Since the aforementioned inclined roller conveying mechanism 61 guides the trajectory of the printing medium entering the receiving platform 3 to ensure that the printing medium follows the trajectory of the guide side 612 when entering the receiving platform 3, and since it is necessary to change the trajectory of the printing medium entering the receiving platform 3, the aforementioned guide side 612 is not fixedly arranged on the receiving frame 1, and its position can be laterally translated relative to the transmission inclined roller 616. Based on this, the guide side block 612 is movably mounted on the receiving frame 1 via a sliding drive assembly 614 (such as a motor and rack, where the fixed motor drives the movable rack via gears) and multiple sets of linear sliding assemblies 613 (such as slide rails and sliders). Guided by the linear sliding assembly 613, and driven by the sliding drive assembly 614, the guide side block 612 moves along the linear sliding assembly 613 on the receiving frame 1, thereby moving closer to or away from the end of the corresponding drive slant roller 616, thus changing the reference position of the drive slant roller 616 for side conveying. Figure 3 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown.

[0189] In other words, the inclined roller conveying mechanism 61, the bridge plate 611 and the transmission inclined roller 616 of the above structure are relatively fixed on the receiving frame 1 (except for the rotation of the transmission inclined roller 616) and cannot be moved laterally, while the guide side block 612 is movably mounted on the receiving frame 1 and can be moved laterally at the corresponding end of the transmission inclined roller 616.

[0190] Because the aforementioned inclined roller conveyor mechanism 61 has the characteristic of conveying the printing media to the side, and needs to be close to the guide side stop 612; and because the guide side stop 612 is movably assembled relative to the bridge plate 611 and the drive inclined roller 616, there is a lateral movement gap in the guide side stop 612, which can obstruct the printing media conveyed to the side. Therefore, the area of ​​the bridge plate 611 adjacent to the guide side stop 612 has a flat edge forming a planar structure, such as... Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown; the bottom of the guide side stop 612 has a bent transition bottom edge 617, which overlaps and fits laterally at the bottom edge of the side of the bridge plate 611 that mates with the guide side stop 612, as shown. Figure 12 As shown. Under the drive of the sliding drive assembly 614, when the guide side block 612 moves laterally in the printing media conveying direction, the bottom edge 617 of the side block transitions and the corresponding edge of the bridge plate 611 are fitted together in a nested relationship. This results in the guide side block 612 having a limited lateral offset adjustment distance H in the lateral direction. The value of this lateral offset adjustment distance H is usually in the range of 5 to 20 mm. The guide side block 612 can be laterally translated within this lateral offset adjustment distance H range to meet the technical requirements of the lateral misalignment distance of the printing media in the lateral staggered stacking. In the aforementioned mating structure, the printing media conveyed by the bridge plate 611 and the drive inclined roller 616 abuts against the guide side block 612 with one edge of its traveling direction. Since the lateral translation movement gap of the guide side block 612 is located at the bottom of the bridge plate 611, the lateral translation of the guide side block 612 will not cause obstruction to the conveying of the printing media.

[0191] In order to enable the guide side 612 of the inclined roller conveying mechanism 61 to move laterally to adapt to the high-speed conveying of printing media and to form an automated operation, the discharge path offset mechanism 6 has an automatic translation control system for controlling the lateral translation of the inclined roller conveying mechanism 61. The automatic translation control system mainly consists of a counting sensor 7, a sliding stroke sensor 615, a drive motor constituting the sliding drive assembly 614, and a controller.

[0192] More specifically, the counting sensor 7 is located at the output end of the discharge path offset mechanism 6, specifically embedded downstream of the bridge plate 611 of the inclined roller conveyor mechanism 61, close to the guide side 612. This ensures that the printing media conveyed along the guide side 612 will inevitably pass through the detection range of the counting sensor 7 during its journey from the inclined roller conveyor mechanism 61 to the receiving platform 3. The counting sensor 7 is used to detect the number of printing media sequentially entering the receiving platform 3, and feeds back a detection signal to the controller according to a set counting cycle (e.g., 20 sheets per unit, forming a stacking unit, the counting sensor 7 will accumulate 20 sheets and then reset to zero and start accumulating again). The sliding stroke sensor 615 is located at the aforementioned linear sliding assembly 613, and is used to detect the lateral translational stroke position of the guide side 612 driven by the sliding drive assembly 614, and feeds back a detection signal to the controller. The drive motor constituting the sliding drive assembly 614 is used to drive the sliding drive assembly 614 to move in a set direction and stroke under the control command of the controller, so as to drive the guide side block 612 to perform lateral translational reciprocating motion.

[0193] For example, suppose that the horizontally staggered stacked media C collected by the receiving platform 3 is composed of multiple sets of stacking units stacked horizontally in a staggered manner, with the horizontal stagger distance between two adjacent sets of stacking units being 10mm, and each set of stacking units consisting of 20 sheets of printed media stacked in layers. Thus, under the control of the translational automatic control system, the guide sidebar 612 is positioned at a set position, causing the incoming printing media to travel and be output with the guide sidebar 612 as the reference. During this output process, the counting sensor 7 counts the output printing media until it reaches 20 sheets, and then sends a signal back to the controller. Based on this signal, the controller instructs the guide sidebar 612 to move laterally to a set position two. The set position two is 10mm apart from the set position one. At the set position two, the guide sidebar 612 causes the incoming printing media to travel and be output with the guide sidebar 612 as the reference. During this output process, the counting sensor 7 counts the output printing media until it reaches 20 sheets, and then sends a signal back to the controller. Based on this signal, the controller instructs the guide sidebar 612 to move laterally to a set position one, and so on. Thus, by the lateral translation of the guide side 612, the trajectory of the printing media entering the receiving platform 3 under the guide is changed, so that the printing media entering the receiving platform 3 in sequence are stacked in a lateral staggered manner according to the settings, and finally the lateral staggered stacked media C is formed.

[0194] In other words, in this embodiment, the relative positions of the inclined roller conveying mechanism 61, which constitutes the discharge path offset mechanism 6, and the transmission inclined roller 616 on the receiving frame 1 are fixed; only the guide side 612 can move laterally. Therefore, the motor constituting the sliding drive assembly 614, under the control command of the controller, drives the sliding drive assembly 614 to move according to a set direction and stroke, thereby driving the guide side 612 of the discharge path offset mechanism 6 to perform lateral reciprocating motion.

[0195] like Figure 2 , Figure 3 , Figure 15 As shown, the wind power mechanism 62 is arranged above the inclined roller conveyor mechanism 61 and is used to apply a local lateral force to the printing medium in the direction of travel at the guide side 612 of the inclined roller conveyor mechanism 61, so as to force the printing medium to accelerate and move to the side during the conveying process on the inclined roller conveyor mechanism 61.

[0196] Specifically, the wind power mechanism 62 includes a fan bracket 621 and multiple sets of small electric fans 622 arranged on the fan bracket 621. The fan bracket 621 is fixedly supported on the receiving frame 1 and located above the inclined roller conveyor mechanism 61. The sets of small electric fans 622 are arranged on the fan bracket 621 along the direction of printing media conveying, and the arrangement of these small electric fans 622 basically corresponds to the longitudinal length of the conveying working surface of the inclined roller conveyor mechanism 61. The air outlet of the wind power mechanism 62 faces the conveying working surface of the inclined roller conveyor mechanism 61, and the direct conveying path of the air force blown by the wind power mechanism 62, with the guide side 612 as a reference, is perpendicular to the plane of action of the inclined roller conveyor mechanism 61. That is to say, the direct conveying path of the air force blown by the wind power mechanism 62 is basically parallel to the guide surface of the guide side 612.

[0197] In the cooperation between the aforementioned wind power mechanism 62 and the aforementioned inclined roller conveyor mechanism 61, the air force blown by the wind power mechanism 62 cannot cover the lateral width of the currently conveyed printing medium in the transverse direction (with the printing medium conveying direction as the longitudinal direction) of the inclined roller conveyor mechanism 61. It can only act in the area of ​​the currently conveyed printing medium near the guide side 612. That is, the direct action area of ​​the air force blown by the wind power mechanism 62 in the conveying working surface of the inclined roller conveyor mechanism 61 should be close to the guide side 612. Only in this way can it cooperate with the inclined roller conveyor mechanism 61 to generate a strong lateral side-adjusting torque on the printing medium being conveyed, forcing the printing medium to quickly move to the side in the inclined roller conveying, thereby ensuring that the printing medium output by the aforementioned inclined roller conveyor mechanism 61 travels along the guide side 612 to the receiving platform 3.

[0198] For stacked paper printed by a conventional high-speed printer, which is either A3 or A4 paper, regardless of whether the paper is fed along its length or width, the direct area of ​​the air force of the wind mechanism 62 on the conveying working surface of the inclined roller conveyor 61 should be within a range of 200mm, preferably 150mm, transverse to the paper conveying direction, with the guide side 612 as the reference. That is, when acting on the currently conveyed printing medium, it is within a range of 200mm transverse to the printing medium conveying direction with the guide side 612 as the reference. In other words, the width of the direct air force action area is 200mm, starting from the guide side 612. When the printing medium being conveyed arrives at the inclined roller conveyor 61, the air force of the air mechanism 62 acts on the area of ​​the printing medium near the guide side 612. During the continuous conveying of the inclined roller conveyor 61, the printing medium being conveyed is forced to move towards the edge of the inclined roller conveyor 61 with the guide side 612 as the alignment reference.

[0199] The small electric fans 622 of the aforementioned wind power mechanism 62 can be driven synchronously by the same motor, or driven independently by different motors but operating in coordination. Regardless of the operating mode, the wind force blown by each small electric fan 622 of the wind power mechanism 62, directly acting on the currently conveyed printing medium, should be controlled within the range of 2 to 50 Pa, preferably within the range of 5 to 10 Pa. The specific setting of the wind pressure of the wind power mechanism 62 on the printing medium should be based on the material stiffness of the current printing medium. Generally, printing media with lower stiffness can withstand lower wind pressure, while printing media with higher stiffness can withstand higher wind pressure. The stiffness of the printing medium is related to its basis weight, manufacturing process, etc. A wind pressure range of 5 to 10 Pa can basically meet the reliable and stable transmission of different basis weights (60 to 300 gsm) of paper used in conventional printers.

[0200] Based on the aforementioned material path offset mechanism, to ensure smooth and stable transport of the printing media and prevent it from curling or drifting, thus guaranteeing the reliability of side-mounted transport, a first pressing transmission mechanism 5, which drives along the direction of printing media transport, is also arranged on the receiving frame 1 above the aforementioned inclined roller conveyor mechanism 61. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 15 , Figure 17 and Figure 18 As shown. The first pressing transmission mechanism 5 has a front shaft—the first shaft 51—that first engages with the currently conveyed printing medium, and a rear shaft—the second shaft 52—that later engages with the currently conveyed printing medium. It also includes multiple first media guide belts 53, which are circulated between the first shaft 51 and the second shaft 52. These first media guide belts 53 are spaced apart along the axial direction of the first shaft 51 and the second shaft 52. The aforementioned first shaft 51 or second shaft 52 acts as the drive shaft of the driven assembly, driving the first media guide belts 53 and other associated shafts to rotate in the direction of printing medium transport. During the circulatory transmission, the first media guide belts 53, in conjunction with the conveying working surface of the lower inclined roller conveyor mechanism 61, form a channel that allows the currently conveyed printing medium to enter and prevents drift. Typically, to ensure the reliability of the printing medium entering this conveying channel, the first shaft 51 of the first pressing transmission mechanism 5 is positioned slightly higher than the second shaft 52; however, this height difference is relatively negligible and inconspicuous. Thus, the aforementioned wind power mechanism 62 is arranged within the circulating transmission space of the first medium guide belt 53 of the first pressing transmission mechanism 5.

[0201] In the aforementioned receiving structure, the initial height of the receiving platform 3 is lower than the discharge port of the discharge path offset mechanism (skew roller conveyor mechanism) (typically with a height difference of about 20mm). The second pressing drive mechanism 8 of this structure needs to form a channel for the printing media to enter with the bearing plane 31 of the receiving platform 3, and the first pressing drive mechanism 5 of this structure needs to form a channel for the printing media to enter with the conveying working surface of the skew roller conveyor mechanism 61. Therefore, the first pressing drive mechanism 5 and the second pressing drive mechanism 8 of this structure are arranged on the receiving frame 1 with a slightly inclined structure, with the upstream slightly higher and the downstream slightly lower. If the first pressing drive mechanism 5 and the second pressing drive mechanism 8 are arranged completely independently on the receiving frame 1, there will usually be an interruption in the sequential direction between them, creating a gap where the printing media may deviate from the designated conveying channel during transport. Therefore, the second shaft 52 of the first pressing drive mechanism 5 and the third shaft 81 of the second pressing drive mechanism 8 are staggered in the direction of printing media transport. Specifically, the third shaft 81 of the second pressing drive mechanism 8 contacts the current printing media before the second shaft 52 of the first pressing drive mechanism 5. The second shaft 52 of the first pressing drive mechanism 5 is positioned approximately above the inlet of the receiving platform 3, and the third shaft 81 of the second pressing drive mechanism 8 is positioned approximately above the outlet of the inclined roller conveyor 61. Thus, the first media guide belt 53 of the first pressing drive mechanism 5 bypasses the third shaft 81 of the second pressing drive mechanism 8 and is fitted onto the second shaft 52 of the first pressing drive mechanism 5. Similarly, the second media guide belt 83 of the second pressing drive mechanism 8 bypasses the second shaft 52 of the first pressing drive mechanism 5 and is fitted onto the third shaft 81 of the second pressing drive mechanism 8. Figure 2 , Figure 3 , Figure 4As shown. Of course, based on the slightly inclined arrangement of the first pressing drive mechanism 5 and the second pressing drive mechanism 8, the second shaft 52 of the first pressing drive mechanism 5 is positioned slightly lower than the third shaft 81 of the second pressing drive mechanism 8. However, based on the aforementioned cooperation relationship between the first pressing drive mechanism 5 and the second pressing drive mechanism 8, and based on the initial position of the bearing plane 31 of the receiving platform 3 being lower than the conveying working surface of the inclined roller conveyor mechanism 61, in order to accommodate the height difference between the conveying working surface of the inclined roller conveyor mechanism 61 and the bearing plane 31 of the receiving platform 3, and to form a reliable conveying channel, the first pressing drive mechanism... The height difference between the second shaft 52 of the first pressing drive mechanism 5 and the third shaft 81 of the second pressing drive mechanism 8 becomes relatively significant. In this arrangement with a significant height difference, the first medium guide belt 53 and the second medium guide belt 83 between the second shaft 52 and the third shaft 81 risk interfering with the higher-positioned inclined roller conveyor mechanism 61. Therefore, an intermediate shaft is provided at the junction of the first pressing drive mechanism 5 and the second pressing drive mechanism 8, positioned at the bottom. This intermediate shaft is located at the bottom of the area between the second shaft 52 and the third shaft 81, and it deflects and tensions the first medium guide belt 53 and the second medium guide belt 83. Figure 4 and Figure 5 As shown.

[0202] Based on the linkage relationship between the first pressing transmission mechanism 5 and the second pressing transmission mechanism 8, the two adopt the same driving component. The driving component connects any one shaft as the driving shaft, and drives the other shaft as the driven shaft through the medium guide belt.

[0203] In the above technical solution, based on automated control, the controllers of the above-mentioned automatic material receiving control system (automatic lifting control system) and automatic translation control system can be integrated into the same controller and operate according to their respective control logic. They do not necessarily have to be arranged independently, although they can be arranged independently.

[0204] Example 2

[0205] The rest of the contents of this embodiment are the same as those of embodiment 1, except that the inclined roller conveyor mechanism constitutes the discharge path offset mechanism.

[0206] Specifically, the inclined roller conveying mechanism includes an inclined roller support mounted on the receiving frame with a lateral translation structure, multiple rotatable drive inclined rollers sequentially mounted on the inclined roller support along the printing media conveying direction, a bridge plate mounted on the inclined roller support and located around the drive inclined rollers, guide side blocks arranged at one end of these drive inclined rollers along the printing media conveying direction to guide the conveyed printing media, a sliding drive assembly that drives the inclined roller support to lateral translation along the printing media conveying direction on the receiving frame, and a rotation drive assembly that drives these drive inclined rollers to rotate along a set conveying direction; the guide side blocks are fixedly connected to the inclined roller support and have a relatively fixed structure with the drive inclined rollers and the bridge plate, and cannot be displaced.

[0207] Compared to Embodiment 1, this embodiment involves laterally shifting the entire inclined roller conveyor mechanism to change the trajectory of the printing medium being conveyed along the edge. In other words, in this embodiment, the motor constituting the sliding drive assembly, under the control command of the controller, drives the sliding drive assembly to move according to a set direction and stroke, thereby causing the entire inclined roller conveyor mechanism of the discharge path offset mechanism to perform lateral reciprocating motion.

[0208] In this embodiment, since the lateral translation distance of the inclined roller conveyor is relatively small, i.e., reciprocating within the range of 5 to 20 mm, the pneumatic mechanism and the first pressing drive mechanism that work in conjunction with the inclined roller conveyor can be directly arranged on the receiving frame without translating with the lateral movement of the inclined roller conveyor. Alternatively, the pneumatic mechanism and the first pressing drive mechanism can be arranged on the inclined roller support, translating with the lateral movement of the inclined roller conveyor. In this case, the first pressing drive mechanism should not be connected to the second pressing drive mechanism above the receiving platform.

[0209] Example 3

[0210] The rest of the content of this embodiment is the same as that of embodiment 1, except that:

[0211] The direct transmission path of the wind force blown by the wind power mechanism takes the guide side of the inclined roller conveyor mechanism as a reference and matches the acting plane of the inclined roller conveyor mechanism at an obtuse angle. That is to say, the extension line of the direct transmission path of the wind force blown by the wind power mechanism matches the extension line of the guide surface of the guide side. Of course, the direct transmission path of the wind force blown by the wind power mechanism should not act on the guide side.

[0212] In this embodiment, the wind power mechanism is limited by the increased height caused by the inclined arrangement of the small electric fan on the fan bracket. The wind power mechanism is arranged above the first pressing transmission mechanism (if the space formed by the circulating transmission of each medium guide belt of the first pressing transmission mechanism is large enough, it can also be installed in the space formed by the circulating transmission of each medium guide belt of the first pressing transmission mechanism).

[0213] Example 4

[0214] The rest of the content of this embodiment is the same as that of embodiment 1, except that:

[0215] The wind-powered mechanism is arranged below the inclined roller conveyor mechanism. The wind-powered mechanism generates negative pressure adsorption at the air outlet, and exerts force on the printing medium conveyed by the inclined roller conveyor mechanism in the form of negative pressure adsorption.

[0216] Of course, since the first pressing transmission mechanism can only be located above the inclined roller conveyor mechanism, the cooperation between the wind power mechanism and the first pressing transmission mechanism is terminated.

[0217] In addition, if the direct action path of the wind force generated by the wind mechanism is arranged at an angle with reference to the guide side, then it is matched with the surface of the printing medium conveyed by the inclined roller conveyor in an acute angle relationship, that is, the air outlet is inclined to the inclined roller conveyor near the guide side.

[0218] Example 5

[0219] The rest of the content of this embodiment is the same as that of embodiment 1, except that:

[0220] Remove the material-blocking protrusion at the bottom of the material-blocking beam, forming a single, integrated stop structure at the bottom of the material-blocking beam to receive the printing media.

[0221] Therefore, if the guide beam in this embodiment slides forward, a large clearance groove needs to be formed on the bearing surface of the receiving platform, which will inevitably damage the bearing function of the bearing surface for the printing media. Therefore, in this embodiment, the guide beam is fixed to the guide bracket and cannot slide, i.e., the slider structure is eliminated.

[0222] Correspondingly, the clearance groove on the receiving platform can be removed; the pressure roller of the stop assembly is directly mounted on the stop bracket in a rotatable structure.

[0223] Example 6

[0224] The rest of the content of this embodiment is the same as that of embodiment 1, except that:

[0225] The receiving platform does not extend into a receiving frame;

[0226] The receiving frame has a groove formed for the sliding of the stop assembly. The material blocking beam and pressure roller of the stop assembly are directly assembled on the receiving frame via a slider, and the material blocking bracket of the stop assembly is removed.

[0227] Example 7

[0228] The rest of the content of this embodiment is the same as that of embodiment 1, except that:

[0229] The guide side of the inclined roller conveyor is driven to move linearly by a screw drive pair structure / synchronous belt drive structure.

[0230] Similarly, the receiving platform uses a rack and pinion drive structure / synchronous belt drive structure to drive linear lifting.

[0231] Example 8

[0232] The rest of the content of this embodiment is the same as that of embodiment 1, except that:

[0233] The pneumatic mechanism of the discharge path offset mechanism is removed, and the discharge path offset mechanism is only conveyed to the side by the inclined roller conveyor mechanism.

[0234] Of course, the corresponding functions will be eliminated once the wind turbine is removed.

[0235] Example 9

[0236] The rest of the content of this embodiment is the same as that of embodiment 1, except that:

[0237] The counting sensors of the translation automatic control system are arranged upstream of the inclined roller conveyor mechanism.

[0238] Example 10

[0239] The rest of the content of this embodiment is the same as that of embodiment 1, except that:

[0240] The counting sensors of the translation automatic control system are arranged upstream of the inclined roller conveyor mechanism.

[0241] Example 11

[0242] The rest of the content of this embodiment is the same as that of embodiment 1, except that:

[0243] The translational automatic control system has two sets of counting sensors: one set is located upstream of the inclined roller conveyor, and the other set is located downstream. The upstream counting sensor is used to periodically count the moving print media, while the downstream sensor detects the output end of the last print media in the current counting cycle. This ensures that the inclined roller conveyor performs the corresponding lateral translational movement when all print media in the current counting cycle has been output.

[0244] Based on this, the counting sensor of the translation automatic control system can also be linked with the printing control system of the printer body. For example, a set of stacking units can be used as a set of printing objects. The number of pages to be printed for each set can be set for the printing control system of the printer body. The printing control system can perform periodic counting of the printing media stacked and printed according to the number of pages printed for each set. The downstream sensor is used to detect the output end of the last printing media of the current counting cycle.

[0245] Alternatively, the printer's own printing control system can directly perform periodic counting and detection of the printing media in the stacking unit, eliminating the need for counting sensors at the receiving device. For example, a set of stacking units can be considered as a set of printing objects. The printer's own printing control system can be set to print the number of pages for each set. The printing control system can then perform periodic counting of the printing media in the stacking unit based on the number of pages printed for each set, and send a corresponding delay to the translation automatic control system according to the set conveying efficiency.

[0246] Example 12

[0247] The rest of the content of this embodiment is the same as that of embodiment 1 or 2, except that:

[0248] The inclined roller structure of the inclined roller conveyor mechanism is replaced by an inclined belt structure, that is, the inclined roller conveyor mechanism is changed to an inclined belt conveyor mechanism.

[0249] This substitution in this embodiment is only a replacement of the transmission structure for the side conveying of the inclined roller conveyor mechanism; the lateral displacement structure of the remaining guide side blocks or the overall lateral displacement structure of the inclined roller conveyor mechanism (inclined conveying mechanism) all adopt the original structure.

[0250] Regarding replacing the drive slant roller structure with a belt structure, two shafts are arranged on the corresponding bracket according to the conveying direction spacing, and a conveyor belt is fitted on the two shafts; it is required that the two shafts form an acute angle fit with the guide side in the printing media conveying direction.

[0251] Example 13

[0252] The rest of the content of this embodiment is the same as that of embodiment 1 or 2, except that:

[0253] The discharge path offset mechanism is arranged upstream of the receiving platform and works in conjunction with the main frame of the printer body.

[0254] In other words, in this embodiment, the discharge path offset mechanism is independent of the receiving platform and is arranged on the main frame of the printer body, at the end of the sequential conveying path of the printer body. The receiving frame is arranged at the discharge port of the discharge path offset mechanism, that is, the discharge path offset mechanism on the main frame cooperates with the receiving platform on the receiving frame.

[0255] Example 14

[0256] The rest of the content of this embodiment is the same as that of embodiment 1, except that:

[0257] The height difference between the bearing plane of the initial receiving platform and the conveying working surface of the inclined roller conveyor is slightly smaller, for example, within 10mm (such as 5mm or 3mm).

[0258] The height difference between the second shaft of the first pressing transmission mechanism and the third shaft of the second pressing transmission mechanism is negligible and inconspicuous. There is no risk of positional interference between the first medium guide belt and the second medium guide belt between the second and third shafts and the higher inclined roller conveyor mechanism. The intermediate shaft set at the connection between the first pressing transmission mechanism and the second pressing transmission mechanism is removed.

[0259] The above embodiments are only used to illustrate the present invention and are not intended to limit it.

[0260] Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications can still be made to the above embodiments, or equivalent substitutions can be made to some of the technical features. For example, the applicable printing media can be any one of the single and flat A3, A4, B3, B4, 8K, and 16K printing media specifications. Or, the printer body can be any other high-speed printer with any other structural form (provided that the material is fed in a stacking manner). These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the present invention.
